Part F

Which principle of relative age dating is important for determining the relative age of igneous rock that has intruded into overlying rock?

ANSWER:

Correct

Part G

A fault (F) breaks three layers of sedimentary rock (S). An igneous intrusion (I1) has broken through the bottommost layer of rock. A second igneous intrusion (I2) has moved up the fault and pooled on top of the uppermost layer of rock. Which event would be considered the youngest?

ANSWER:

Correct

Faults A and B are about the same age, and both are older than the five layers of rock.

Fault A is younger than fault B, and both are older than the five layers of rock.

Faults A and B are about the same age, and both are younger than the five layers of rock.

Fault A is younger than fault B, and both are younger than the five layers of rock.

the principle of original horizontality

the principle of cross­cutting relationships

the principle of intrusive relationships

the principle of superposition

Faulting of rock along F is the youngest event. We know this because all three layers of sedimentary rock have been broken.

The intrusion of I2 is the youngest event. We can know this because I2 sits on top of all other rocks.

Deposition of the three sedimentary layers, S, is the youngest event. We know this because the fault underlies the igneous rocks.

The intrusion of I1 or I2 is the youngest event. Without more information, we cannot know which igneous rock is youngest.

If a sequence of sedimentary units is cut by a fault, what does the principle of cross­cutting relationships tell a geologist?

Hint 1.

Recall what the principle cross­cutting relationships states and how it is used for relative age dating.

ANSWER:

Correct

Part C

Which of the following describes the principle of original horizontality?

Hint 1.

The video showed a sequence of folded sedimentary rocks. What had to occur to form this feature?

ANSWER:

Correct

Part D

The sedimentary units on the left side of the fault are the same as those on the right side.

All of the sedimentary units must have been deposited and lithified before being cut by the fault.

The fault is older than the sedimentary sequence.

Sedimentary layers are laid down horizontally.

The oldest sedimentary unit is located at the base of the sequence, while the youngest is at the top.

Inclusions within a sedimentary rock are older than the sedimentary rock itself.

Folded sedimentary layers were originally laid down flat and later deformed.

A fault or dike that cut a sedimentary sequence is younger than the sedimentary rocks it breaks through.

Undeformed sedimentary layers present on one side of a river­cut canyon are the same as those on the opposite side.

The oldest sedimentary unit is located at the base of the sequence, while the youngest is at the top.

An undeformed sequence of sedimentary rocks is exposed in a large river canyon. Which two principles would be demonstrated by the rocks?

Hint 1.

Think back to the five principles you learned about in the video. Which two would be the most applicable to an undeformed rock sequence that has been eroded by a large stream?

ANSWER:

Correct

Part E

An igneous dike cuts through limestone, but not through the overlying sandstone. Which of the following statements is most accurate?

Hint 1.

Think about how the principles of superposition and cross­cutting relationships are used for this question.

ANSWER:

Correct

principles of lateral continuity and inclusions

principles of superposition and lateral continuity

principles of cross­cutting relationships and superposition

principles of superposition and dating by inclusions

principles of lateral continuity and cross­cutting relationships

First, the sandstone was laid down, next the limestone was deposited, and finally was cut by the igneous dike.

The limestone and sandstone were deposited and then cut by the igneous dike.

First, the limestone was laid down, then intruded by the igneous dike, and lastly the sandstone was deposited.

The igneous dike represents the oldest rock, while the sedimentary rocks are relatively younger.

First, the limestone was laid down, folded and cut by an igneous dike, and finally the sandstone was deposited.

GeoTutor: Constructing an Order of Sequence of Geologic Events ­ Geologic Time Scale

Geologists have divided the whole of history into units of increasing magnitude. This is called the geologic time scale. The entire time scale was originally based on relative dating, since radiometric dating was not available at the time. Absolute dating techniques determine a numerical age of strata given in number of years. Relative dating techniques, on the other hand, determine the age of a stratum relative to other strata (i.e., if it is younger or older), without providing any numerical data. Geologists have been able to determine the relative ages of rocks and any fossils they contain to reconstruct a history that reveals the evolution of Earth’s continents and living organisms using four laws of stratigraphy:

1. Law of Superposition: Younger strata are deposited on top of older strata. 2. Law of Original Horizontality: Strata are deposited horizontally. Tilted strata had been tilted by some geologic event after the time of deposition. 3. Law of Lateral Continuity: Layers of sediment initially extend laterally in all directions. As a result, rocks that are otherwise similar, but are now separated by a valley or other erosional feature, can be assumed to be originally continuous.

4. Law of Cross­Cutting Relationships: Magma intrudes and crystallizes (forming features such as faults and dikes). These features are younger than the strata they cut through.

The geologic time scale subdivides the 4.6­billion­year history of Earth into several units, outlining the time frames of several events of the geologic past. See below for the geologic time scale chart.

of the rocks. Use the laws of stratigraphy to rank these strata.

Rank the strata from oldest to youngest.

Hint 1. The Law of Cross­Cutting Relationships

The volcanic dike (H) must be older than any strata it does not cut through and younger than any strata it does cut through, because the strata it cuts through must have been there before the intrusion of magma.

Hint 2. The Law of Original Horizontality

Pretend the tilted strata are horizontal. That is, “D” is above “A,” “C” is above “A,” and so on. The Law of Original Horizontality states that strata are deposited horizontally in their original states. Tilted strata had been tilted by some geologic event after the time of deposition, but still retain their relative order.

All attempts used; correct answer displayed

Notice that the tilted strata are immediately overlain by horizontal strata. This can only occur if erosion has partially removed the tilted strata so they all terminate at the same depth.

Part B ­ The geologic time scale and unconformities

Gaps in the rock record are called unconformities. Unconformities are caused by periods of erosion that have occurred between periods of deposition, which have erased a portion of the rock record. There are three types of unconformities: (1) angular unconformities occur when tilted strata are overlain by horizontal strata—Click here to see an angular unconformity; (2) disconformities occur when strata are separated by an erosional surface—Click here to see a disconformity); (3) nonconformities occur when strata overlay igneous or metamorphic rocks that are resistant to erosion—Click here to see a nonconformity.

Now use the figure below, which has labeled each of the rock strata/layers from Part A with their respective geologic time periods, to fill in the gaps in the following sentences.

Hint 1. How to determine the missing time period

Identify the youngest and oldest strata in the diagram, and use the geologic time scale provided above to find all of the geologic periods between these ages.

Hint 2. The types of unconformities

The volcanic dike terminating abruptly at a stratigraphic boundary would indicate that erosion has occurred.

Hint 3. The age of unconformities

An unconformity must be at least the age of the strata overlying it and can be as old as the strata below it.

GeoTutor: Constructing an Order of Sequence of Geologic Events – Relative Dating

The ordering of events in geological history has long been a difficult task, but once simple principles were determined observation and logic could be used to determine the order of events. With these principles, one cannot calculate the exact number of years ago an event occurred, but instead the sequence of events can be determined. This is referred to as relative dating. The principles are as follows:

1. The law of superposition: In sedimentary rocks, the rock bed on the bottom must be older than the rock bed on the top. 2. The principle of original horizontality: Sedimentary rocks were originally deposited as flat­lying, horizontal layers.

Angular unconformities represent missing time, whereas nonconformities do not.

Conformities represent missing rock layers.

Nonconformities separate parallel rock layers of the same rock type.

Nonconformities separate two different rock types, whereas angular unconformities form only between strata of the same rock type.

Angular unconformities separate rock layers along nonparallel surfaces.

3. The principle of cross­cutting relationships: Any rock or feature, cutting through another rock or feature, must be younger than the material through which it cuts. (For example, with faults, igneous intrusions such as dikes, or fractures, the first rock must be there for these secondary features to cut through.)

4. Inclusions: Any rock fragments included within another rock must be older than the rock in which they are included. (For example, if eroded fragments of one rock layer become part of another sedimentary rock layer, the rock with the included fragments must be younger than the fragments themselves.)

Part A ­ Basic Principles for Relative Geologic Dating

Below is a geologic structure that illustrates the various principles of relative dating. You will identify the basic principles used in relative geologic dating by dragging labels to their corresponding targets in the image below.

Drag the appropriate labels to their respective targets.

Hint 1. Inclusions in sedimentary rock layers

According to the principle of inclusions, the layer of rock that has inclusions from another rock layer must be younger.

Hint 2. A dike cutting through sedimentary rock layers

The rock layers that the dike cut through must have been there first. This is the principle of cross­cutting relationships.

ANSWER:

2/26/2016 Homework 5 Geologic Time

https://session.masteringgeology.com/myct/assignmentPrintView?assignmentID=1211587 19/41

Correct

As you can see from above, using the logic of these principles when observing sedimentary rock, we can determine a sequence of events.

Now that we have investigated the principles of relative dating, we can use these principles to determine how to read the sequence of geologic events in a location.

Part B ­ Ordering of Geologic Events

The principles of relative dating can be used to understand the order of geologic events. A geologic event can be anything: the deposition of horizontal layers of sedimentary rock, the faulting or folding of rock layers, the tilting of rock layers, the erosion (or wearing away) of rock, the intrusion of volcanic rock within existing rock layers, and so on. Refer to these relative dating principles:

1. Inclusions: Any rock fragments included within another rock must be older than the rock in which they are included. (For example, if eroded fragments of one rock

2/26/2016 Homework 5 Geologic Time

https://session.masteringgeology.com/myct/assignmentPrintView?assignmentID=1211587 20/41

layer become part of another sedimentary rock layer, the rock with the included fragments must be younger than the fragments themselves.) 2. The principle of cross­cutting relationships: Any rock or feature, cutting through another rock or feature, must be younger than the material through which it cuts. (For example, with faults, igneous intrusions such as dikes, or fractures, the first rock must be there for these secondary features to cut through.)

3. Angular Unconformity: It consists of tilted or folded sedimentary rocks that are overlain by younger, more flat­lying strata. An angular unconformity indicates that during the pause in deposition, a period of deformation (folding or tilting) and erosion occurred.

4. Tilting or deformation could occur to an otherwise horizontally layered sedimentary rocks. Most layers of sediment are deposited in a nearly horizontal position. Thus, when we see rock layers that are folded or tilted, we can assume that they must have been moved into that position by crustal disturbances after their deposition. In such an instance, the tilted structure will be younger than the orginal horizontal layers.

Order the five images below along the timeline based on the sequence of geologic events. To find the oldest, look for the image that shows the least geologic changes. To find the youngest, look for the picture that has the most geologic changes.

Rank from oldest to youngest.

In the picture where the gray layer first appears, the layer must be younger than the layers above and below because it has inclusions of both layers of rock within it according to the principle of inclusions. Therefore, this event must have happened after the picture without the gray layer. This can occur when igneous rock intrudes between layers of sedimentary rock and incorporates pieces of the rock layers above and below into the cooling magma.

Hint 2. The oldest and the youngest geologic features/events

The oldest geologic feature should have the least geologic changes and the youngest should have all features from the previous events.

Gigapan: Virtual Fieldwork—Relative Dating and Unconformities

Geologists can determine the geologic history of an area by describing rock outcrops and analyzing the layers of rock. Today you will be a geologist visiting a rock outcrop virtually. You will be able to zoom in and out of the Gigapan image to explore the outcrop and determine the relative ages of rock layers and the geologic history of the area by applying your knowledge of the principles of geology and unconformities.

The principles of geology that you will use in this example are:

The law of superposition: A sedimentary rock bed on the bottom must be older than the rock bed on the top. The principle of original horizontality: Sedimentary rocks were originally deposited as flat­lying, horizontal layers. The principle of lateral continuity: Sedimentary layers, when formed, extended horizontally in all directions.

You will also use your knowledge of unconformities, features created when deposition stopped, uplifting and erosion occurred, and, after a period of time, sedimentation began anew above the eroded layer. There are three main types of unconformities:  

A nonconformity is found where igneous or metamorphic rocks have eroded and then sedimentary rock layers are deposited above. A disconformity is a break between parallel sedimentary rock layers above and below. Disconformities represent times when sediments were not deposited or were eroded. An angular unconformity is found where sedimentary layers were tilted and eroded and younger and more flat­laying sedimentary layers were deposited above.  

In this exercise, you will use Gigapan technology to:

become familiar with interpreting rock outcrops, understand the sequence of events that occurred as these rocks formed and changed over time, and identify the location of an unconformity in this outcrop and provide evidence for its type.

Gigapan technology mosaics thousands of photos together into a single image, allowing you to zoom in and see the tiniest of details. Imagine zooming in on a grain of sand on a photo of a beach!

Instructions for all Parts:

1. Launch the Gigapan image http://www.gigapan.com/galleries/10030/gigapans/129421 2. You can zoom into the image to take a close look at the angular unconformity.

Instructions for Part A:

1. Scroll down and click on the  Google Earth link   on the Gigapan site to launch the Gigapan image  in Google Earth. 2. Close the photo by clicking on Exit Photo to see your field site location in Google Earth. 3. Zoom in or out to determine your location. Also, on the upper right side, your will find the north arrow. If “N” is not aligned with “North” move it to North. This will ensure that the alignment of your field site is directly facing you in an east­west direction.

4. You can reopen the Gigapan image by clicking on Angular Unconformity, west of El Paso, Texas on the left pane of Google Earth. 5. Do not close Google Earth.

Part A ­ Locating your field site

As a geologist, you always want to first locate your field site on a map. It helps other geologists to locate the field site for future studies and helps you look for relationships with data from other nearby field sites. Now, determine where you are (your field site) in the world. Choose the map that best locates your field site.http://www.gigapan.com/galleries/10030/gigapans/129421

https://session.masteringgeology.com/myct/assignmentPrintView?assignmentID=1211587 26/41

Rock units tell us about Earth’s past, so if we find evidence of geologic processes that have directional components (direction of plate movement, folds and faults, mineral foliation, wind and water currents, etc.), we need to be able to accurately reconstruct those directions. Also, in terms of the scientific method, it helps other geologists to be able to recreate the field investigation step­by­step to confirm or refute any previous findings.

Imagine visiting this outcrop, standing at the location where the Gigapan image was taken, and observing the natural and built features around you. Choose the most accurate representation of the outcrop’s orientation and your vantage point (where you are standing in relation to the outcrop). The representations below depict you and the outcrop as viewed from above. Similar to how you identified the location of this outcrop in the previous part, use Google Earth at a multiple zoom levels. The yellow dot is the point where the Gigapan image was taken.

Instructions for Parts C and D:

1. Exit Google Earth and go back to the Gigapan image for Angular Unconformity, west of El Paso, Texas. 2. Examine the outcrop carefully, and make note of the orientation of the layers of sedimentation in this image. Are all of the rock layers running in the same direction? Does the formation contain layers running at different angles?

3. Recall that angular unconformities refer to the junction between sedimentary rocks at an angle and rocks that are more horizontal and represent a time when the rocks were uplifted and eroded. Can you see the evidence of uplift and erosion in the image?

Part C ­ Analysis of an outcrop sketch

Where you see layers of sedimentary rock at an angle in contact with rocks that are horizontal, they are separated by a surface called an angular unconformity. This erosion surface represents a time when rocks were eroded before new layers of rock were formed. This can also occur during a pause in deposition, when a period of deformation (such as folding or tilting) has occurred.

Part D ­ Making observations I

Simple yet thoughtful observation exposes the history of an outcrop. The sedimentary rocks in the Gigapan image were formed as sediment accumulated as layers that stacked atop older layers. As layers became lower in the stack sequence and covered by newer layers, they became rocks.

If this area had been under water, the shells of organisms would have become limestone, a rock that can’t be identified visually but can be identified using field­based tests. Underwater movement of sediment may also create mixes of fine and coarse grains. This sediment becomes conglomerate, a rock clearly identifiable given its combined

Part A ­ Calculating the Age of a Fossil Based on the Number of Half­lives Elapsed

Each isotope has a unique half­life. The half­life of an isotope is the time taken for half of the starting quantity to decay (with a ratio of 1:1). After two half­lives, there will be one­ fourth of the original parent sample and three­quarters would have decayed to the daughter product (with a ratio of 1:3). After three half­lives, the ratio becomes 1:7, and so forth.

The graph, for instance, shows that assuming the half­life of a sample is 4 months, then in 4 months, there will be 0.5 gram of the parent element and 0.5 gram of the daughter element will be produced. In month 8 (which is two­half­lives), there will be only 0.25 gram of parent element left and 0.75 gram of daughter element; that is, one­fourth of the parent sample (in red) is left, and in month 12, there is only one­eighth of the parent element.

You attend a geology lab where you are asked to estimate the age of a fossil. The ratio of parent to daughter elements in the fossil sample is 1:7. You know that fossils are the remains of living organisms, which have some amount of C­14 isotope. The C­14 isotope, which has a half­life of 5730 years, begins to decay as the organism dies.

Are You a Professional? A certified medical assistant (CMA) employed by an obstetrician/ gynecologist calls her former medical assistant instructor to inform her of an opening for a clinical assistant in the obstetrics and gynecology (OB-GYN) clinic. After describing the position and its responsibilities, the CMA says, “We really need another person in the clinical area. I’m the doctor’s only nurse.”

Surprised by the comment, the instructor inquires, “When did you go back to school to become a nurse?”

She replies, “Oh, I didn’ t, but everyone thinks I am his nurse. I do everything a nurse does.”

The title of this text, Medical Law, Ethics, and Bioethics for the Health Professions, presents three distinct topics: medical law, ethics, and bioethics. Such distinction, however, is for the sake of clarity. Discussion of any one of these topics will include the others. Any study of health law will surface themes of ethics and bioethics. Conversely, discussing ethics and bioethics without considering the law is futile.

LAW

Laws are societal rules or regulations that are prudent or obligatory to observe. Failure to observe the law is punishable by the government and/ or law enforcement agencies. Laws are designed to protect the welfare and safety of society and to resolve conflicts in an orderly and nonviolent manner. They constantly evolve in accordance with an increasingly pluralistic society. Laws have governed humankind and the practice of medicine for thousands of years. Today federal and state govern- ments have constitutional authority to create and enforce laws. A brief look at these laws, their sources, and their definitions appears in subsequent chapters.

Medical law is essential in regulating licensure of health-care professionals and institutions, pro- viding for client safety, protecting the client-provider relationship, and identifying liability for health-care professionals and institutions. Health law also regulates insurance and managed care as well as federal public health programs. It also has established standards for reproduction and birth issues as well as life and death decisions.

ETHICS

Ethics is a set of moral standards or a code for behavior to govern an individual’s interactions with other individuals and within society. Joseph Fletcher (1905-1991), an American professor who pio- neered in the field ofbioethics, differentiates morals from ethics, stating, “‘morality’ is what people do in fact believe to be right and good, while ‘ethics’ is a critical reflection about morality and the

4 Unit I Understanding the Basics

rational analysis of it.” According to Fletcher, for example, “Should I terminate pregnancy?” is a moral question, whereas “How should I go about deciding?” is an ethical concern.

Although laws are more apt to be rules applied to and observed by all, different cultures have different moral codes. Cultural differences exist relative to age, gender, sexual orientation, ethnic heritage, educational preparation, life experiences, spiritual influences, role models and mentors, economics, values, internal milieu, and health and illness. Every standard for ethics is culture-bound. Therefore, there are few if any universal truths in ethics because it is difficult to identifY customs as being either correct or incorrect. It is also true that one person’s moral code has no special status relative to another person’s moral code; it is only one among many. See Chapter 12, A Cultural Per- spective for Health Professionals, for further discussion on the influence of culture.

Ethical standards can be personal, organizational, institutional, or worldwide. Ethics refers to the various codes of conduct that have been established through the years by members of many pro- fessional organizations, including the medical profession. A number of medical codes appear in the appendices and on DavisPlus.

BIOETHICS

Bioethics refers to the ethical implications of biomedical technology and its practices. Bio refers to life, and issues in bioethics are often life-and-death issues. Edmund D. Pellegrino, Professor Emeritus of Medicine and Medical Ethics at Georgetown University, states that “bioethics, still in its infancy, is routinely called on by the government to provide political cover for controversial public health decisions involving the life and death of Americans.” In other words, political leaders often look to bioethical discussions to guide them in making decisions regarding controversial public health issues. Specialists in the field ofbioethics provide the platform for this decision making.

Since former President Clinton established a National Bioethics Advisory Commission (NBAC) in 1995, subsequent presidents have established their own commission to provide input to the pres- ident and national leaders on issues ofbioethics. In April2010, President Barack Obama appointed members to his Presidential Commission for the Study ofBioethical Issues. Obama mandated that this Commission address potential bioethical issues through advancements in biomedicine and “related areas of science and technology.” The Commission plays a key role in keeping the President informed about bioethical issues.

The challenge to bioethics created by modern medicine and research in the past few decades is staggering. Rapid changes in medicine and technology offer unique and sometimes overwhelming choices to clients and their families. Consumers more actively involved in their health care and quite knowledgeable of medical technology and its implications question medical professionals as they have never before been questioned. The public carefully scrutinizes medical technology and how it relates to their daily lives. Thus, the application ofbioethics in everyday life provides opportunities, challenges, enthusiasm, and sometimes difficult choices.

COMPARING MEDICAl lAW, ETHICS, AND BIOETHICS

Law, ethics, and bioethics are different yet related concepts. Laws are mandatory rules to which all citizens must adhere or risk civil or criminal liability. Ethics often relate to morals and set forth uni- versal goals to try to meet, but there is no temporal penalty for failing to meet ethical goals as there is apt to be in law. However, law in the United States has been and continues to be a driving force in shaping ethics.

Confusion over the interpretation oflaw, ethics, and bioethics is understandable. They sometimes conflict. Consider the following example for further clarification:

The U.S. Supreme Court addressed the issue of abortion in Roe v Wade, 410 U.S. 113, 1973. The law states that during the first trimester, pregnant women have a constitutional right to abortions, and the state has no vested interest in regulating them at this time. During the second trimester, the state may regulate abortions and insist on reasonable standards of medical practice if an abortion

Chapter 1 Medical Law, Ethics, and Bioethics 5

is to be performed. During the third trimester, the state’s interests override pregnant women’s rights to abortions, and the state may deny abortion except when necessary to preserve the health or life of the mother.

The personal ethics of a provider or health-care professional may dictate non participation in an abortion or any abortion-related activities. Bioethics and the allocation of scarce resources are evi- denced by some state statutes that have denied the use of state funds for an abortion or strive to make abortions less available. As demonstrated by this example, sometimes law, ethics, andbioethics conflict.

IN THE NEWS

As a result of two U.S. Supreme Court rulings that prohibit parents from havi ng a bsolute veto over their daughters’ decision to have an a bortio n, many state

legislatures rushed to tighten controls on abortions . As of 2011, only Washingto n, Oregon , New Yo rk, Vermont, Connecticut, Hawaii , Ma in e, and Washingto n DC had no pare nta l notifi- cation or consent laws related to minors seeking abortion (see Fig. 1-1 ). Thirty-six states re- quire some involvement in a minor’s dec is ion; 22 states require parental consent, 10 states req uire only parenta l notification , and 4 states require both parental consent and notification . This information changes yearly as state legislative bodies struggle to exercise control over a bortions in their state. Sometimes, such legislation is later overt urned by the U.S. Supreme Court . Legal attempts continue the move to rescind Roe v Wade.

Figure 1-1. U.S. map showing states requ iring no parent notification and/or consent for a minor’s abortion.

THE IMPORTANCE OF MEDICAl lAW, ETHICS, AND BIOETHICS

There are many reasons that make medical law, ethics, and bioethics important for health-care pro- fessionals. It is necessary to follow health-care laws and to examine one’s actions in light of both laws and ethics. It is helpful to learn more from the bioethical issues that clients face and to appre- ciate differences in moral reasoning among individuals and various cultures. Also, there is the need to confront personal biases and bigotry.

6 Unit I Understanding the Basics

In addition, there are political and economic factors that are relevant to the importance of medical law, ethics, and bioethics. They include:

• Demands of society for quality health care at minimal personal cost • The debate over whether health care is a right or a privilege • The equality of the distribution of and access to emerging medical technology • The controversy among the political arena, national health-care reform, and the consumer

over who pays for health care and how it is paid • The powerful role of medical insurance and managed care.

Thoughtful consideration of the reasons identified here as well as the political and economic factors fosters mature decision making and quality health care for clients.

TODAY’S HEALTH-CARE CLIMATE

There is much in today’s health-care environment to challenge any health-care professional’s ethics, values, and practices. Just a few are identified here for reflection.

• Consumers are bombarded with medical information. The media, both printed and elec- tronic, report on many aspects of health care. This immediate access of information empow- ers consumers to ask more questions of medical professionals, allowing them to be better informed about choices.

• Increasingly, hospitals and ambulatory care centers are establishing ethics committees and/or institutional review boards (IREs) that enable community resource persons, educators, and providers to grapple with ethical dilemmas both before and after they occur in the clinical setting. Laws and ethical standards designed to protect clients and establish guidelines for the medical community represent an effort to create a climate for an equitable exchange between client and provider. The primary goal of an ethics committee is to have a plan in place before a crisis occurs. IRBs have been empowered by the U.S. Food and Drug Adminis- tration (FDA) and the Department of Health and Human Services (DHHS) to monitor, review, and oversee any medical research involving human subjects. An IRB is required if there is either direct or indirect support from the DHHS.

• Medical technology is advancing at a more rapid rate than legal and ethical standards can address. Consider the time without antibiotics, when premature infants died due to lack of neonatal intensive care and when invasive surgery rather than a computed tomography scan was the only method to reveal problems with internal organs. There are a number of medical advances likely to occur in the next decade. Many may come with a flurry of ethi- cal and bioethical implications that will create debate in the medical community. They include: • Restoring irreversibly damaged hearts by replacing dead heart muscle with new laboratory-

grown muscle after a heart attack • Using harvested skin cells obtained through a small biopsy and suspended in a solution to

be sprayed directly _onto a major burn area. These cells rapidly divide to cover the wound up to 80 times larger than the donor site

• Using computer-assisted therapy sessions to identify depression and excessively negative thoughts in the treatment of clients

• Using high-technology brain scans to detect the earliest signs of both plaques and tangles found in Alzheimer disease and using a vaccine to stimulate the body’s own immune response to wipe out the plaques once identified

• Increasing numbers of specialists in medicine make it more difficult to coordinate client care. It is quite conceivable that a client has a primary care provider, a neurologist, a nephrologist, and an oncologist, all providing care. If hospitalization is necessary, is the pri- mary care provider or a hospitalist in charge? Who coordinates, and who approves care? Who decides the appropriate course of action in the case of conflicting medical opinions?

Chapter 1 Medical law, Ethics, and Bioethics

Although specialization may enhance quality health care, it demands greater coordination for clients to benefit, and it increases the cost of medical care. Managed care policies and providers will in part dictate how medical choices are made.

• Costs of medical care have risen exponentially. In 1940, a normal infant delivery cost

7

$35 for 10 days of inpatient hospital care. The delivering physician received an additional $35. In 1990, a normal delivery cost an average of $3300 for a 2- to 3-day inpatient hospital stay. In 2005, hospitalization for normal delivery and a 1- to 2-day hospital stay was $5200. The factors affecting the cost of a birth are: whether it is a vaginal or cesarean delivery, if there are complications, and the length of the hospital stay. Infant delivery is most expen- sive in the Northeast and on the West coast and least expensive in the South. In 2010, the typical cost of a vaginal delivery without complications ranged from about $9000 to $17,000 or more. The typical cost for a cesarean delivery without complications or a vaginal delivery with complications ranged from $14,000 to $25,000 or more. .

The importance of these issues is further evidenced by the struggle that has been made through the past couple of decades to pass some form of a national health-care reform in the nation’s capital. It finally happened in 2010, but not without a great deal of political maneuvering and posturing.

ETHICAL ISSUES IN MODERN MEDICINE

Many situations arise in the practice of medicine and in medical research that present problems requiring moral decisions. A few of these can be illustrated by the following questions.

Should a parent be able to refuse a mandated immunization for his or her child? Does public safety supersede an individual’s right? Is basic health care a right or a privilege? Who dictates client care- the client, the provider, or the health insurance company? Who pays for the care of children with very serious and life-threatening birth defects? Should more medical attention be paid to a “cure” or for “prevention?” How should legal abortions be funded? Is it important that everyone receive equal treatment in medical care? What are the issues related to prolonging life or assisted death for individuals with terminal illnesses? What criteria determine who receives donor organs? Should stem cell research be limited or advanced?

None of these questions has an easy answer, and most individuals do not even think about them unless suddenly and personally faced with one or more of them. These questions and other possi- bilities are the reason for entering into a discussion of pertinent bioethical issues. For some, answers can be found in ethical codes.

CODES OF ETHICS

For generations ethical codes have been written to further clarify medical law and ethics. Many codes have become law. Professional codes have evolved throughout history as practitioners grappled with various ethical and bioethical issues. Increasingly, groups of medical professionals have defined how members of their profession ought to behave. Below are a few examples.

The Hippocratic Oath (see Appendix 1), although not prominent in medical schools today, still carries significant weight among the medical community. The oath, which was first written in the fifth century B.C., was Christianized in the lOth or 11th century A.D. to eliminate reference to pagan gods. The Hippocratic Oath protected the rights of clients and appealed to the inner and finer instincts of the physician without imposing penalties.

The Geneva Convention Code of Medical Ethics, established by the World Medical Association in 1949, is similar to the Hippocratic Oath. This code refers to colleagues as brothers and states that religion, race, and other such factors are not a consideration for care of the total person. This code reflects the fact that medicine was becoming available to all during this era.

The Nuremberg Code was established between 1946 and 1949 as a result of the trials of war criminals after World War II. This code suggests guidelines for human experimentation and is

8 Unit I Understanding the Basics

directed to the world. The writers hoped that the code would ensure the safety of humans in the years to come.

The Declaration ofHelsink1~ written between 1964 and 1975, is an update on human experimen- tation. Much more detailed than the Nuremberg Code, it includes guidelines for both therapeutic and scientific clinical research. Unlike the Nuremberg Code, the Declaration of Helsinki is directed to the world of medicine rather than the world at large.

The American Medical Association (AMA) established the Principles of Medical Ethics in 1847 and updated it in 1957, 1980, and again in 2001 (see Appendix 1). The preamble and nine princi- ples have served as guidelines for physicians for many years. The document “Current Opinions of the Judicial Council of the American Medical Association” is intended as an adjunct to the revised Principles of Medical Ethics. Both documents are pertinent to physicians and their assis- tants today.

The number of professional medical organizations with written ethics codes is numerous. The codes are available on the Internet by searching the particular association and then for its code of ethics. A few are identified here:

• American Academy of Professional Coders (AAPC) • International Medical Informatics Association (IMIA) • National Association of Emergency Medical Technicians (NAEMT) • American Osteopathic Association (AOA) • American Association of Naturopathic Physicians (AANP) • American Chiropractic Association (ACA) • National Certification Commission for Acupuncture and Oriental Medicine (NCCAOM) • National Medical Association (NMA) • American Nurses Association (ANA)

By far the most important code directed to the ambulatory care professional is the AAMA Medical Assistant Code of Ethics and AAMA Medical Assistant Creed directed to the medical assistant (MA) in the ambulatory setting (see Appendix 1). The code was adopted by the American Association of Medical Assistants and appears in its constitution and bylaws. It provides guidelines to assist MAs in serving their profession in an ethical and professional manner. This code, as well as most other ethical codes, identifies to society at large what the standards are for the profession.

A number of codes have appeared that deal more with the rights of clients than the responsibil- ities and guidelines for health-care providers. They include numerous Patient Bill of Rights estab- lished by the American Hospital Association (AHA) and federal and state governments as well as individual hospitals and institutions. Contact the hospital nearest you for a sample of a patient bill of rights, or refer to DavisPlus for the sample from the AHA; they are all quite similar in content. Increasing in popularity are patient bills of rights specific for ambulatory health care. They are usu- ally written by specific clinics and generally include the right to be respected, right to access your medical record, right to receive a second opinion, right to participate in your health care, and the right to have your privacy protected at all times. A number of samples can be seen on the Internet by searching for entities such as the Cleveland Clinic and the Mayo Clinic.

The 2010 Healthcare Reform Bill includes a Patient Bill of Rights that has an entirely different scope. This portion of the bill is designed to ensure that there is affordable health care for everyone; it is designed to put consumers back in charge of their health coverage and prevent insurance carriers from certain practices to ban clients from coverage. The purpose of any patient bill of rights is to make certain clients know their rights. It can be helpful to recognize that in some cases clients always had these rights but were not aware of them.

The most challenging aspect of any ethical code is its personal application. Many books have been written on the subject, and decades of scholarly debate have sought effective criteria for making ethical decisions. No one method is the result. What is certain, however, is that how each individual makes an ethical decision is very personal. The Ethics Check questions identified below may be helpful as you begin to think about medical law, ethics, and bioethics as a health- care professional. ·

Chapter 1 Medical Law, Ethics, and Bioethics

ETHICS CHECI< Blanchard and Peale, in The Power of Ethical Management, developed a set of questions to serve as an “ethics check” that is a useful tool for a person facing an ethical dilemma. These

questions suggest that ethics is a very personal concept and a personal decision. Consider Blanchard and Peale’s three questions to include in a personal code of ethics:

1. Is it legal or in accordance with institutional or company policy? 2. Does it promote a win-win situation with as many individuals (client/employee/employer)

as possible? 3. How would I feel about myself ifi read about my decision or action in the daily newspaper?

How would my family feel? Could I look myself in the mirror? (Fig. 1-2.) e According to Blanchard and Peale, if the answer to any one of the three questions is no, consider

the action unethical. If the answer to all three questions is yes, the action is ethical. The identification of such a simple personal code of ethics can help to clarify actions, and these Ethics Check questions may provide further guidelines on how to act when in a difficult situation.

An individual will have greater difficulties remaining ethical in an organization in which the highest leaders are not ethical in their actions. It helps if the leader of a group is ethical, setting the standard and making it easier for everyone else to be ethical. However, ethical actions may and should come from anyone, regardless of status.

Case Study You are the clinic manager in a large multi provider medical center. There is no upward mobil- ity in this center, and you relish a new challenge. It is a rather slow day, and you use your office computer to access the Internet to do a job search. You find four jobs that are exciting, and you send your resume via the Internet. As you disconnect from the Internet, you recall that it is easy to trace access to sites on the Internet that you have just used for personal business.

Apply the Ethics Check to this case study. What is your conclusion?

Figure 1-2. Ethics Check question: How would I feel if I saw my decision in the newspaper?

10 Unit I Understanding the Basics

APPLYING MEDICAL LAW, ETHICS, AND BIOETHICS AS A PROFESSIONAL HEALTH-CARE EMPLOYEE

The significant conflict that often arises among medical law, ethics, and bioethics mandates that individuals choosing the health professions be people of high moral standards. They should be clear, open, and knowledgeable about their personal choices and beliefs and be able to recognize vast diversity in a pluralistic society. Health-care professionals must feel comfortable in a “servant” role while maintaining their own integrity and the respect of their clients.

Individuals employed in a service-oriented industry such as health care are expected to have cer- tain characteristics. The health professional must always be tactful and should know instinctively when speaking is wise and when listening is better. The health-care employee is an important com- munication link between the client and the provider.

Anyone in a health-care profession is in a nonreciprocal relationship with clients. The professional serves the client and gives the client full respect even when the client is disrespectful. Health-care professionals will want to act and speak nonjudgmentally of their clients and their activities, offering information rather than opinions. Clients expect to be treated with courtesy and understanding. Only the most caring and sensitive of employees can handle day after day of sick, hurting, and com- plaining clients and remain objective yet compassionate and positive.

Physician- and provider-employers require that their employees be diligent and knowledgeable in every detail of the job. Such knowledge and training can come only through professional prepa- ration that is demanding and exacting and continues throughout employment. Professionals who are flexible and take initiative will be an asset to their employers.

Honesty and integrity are traits required of the employee. Health-care professionals must always remember to practice only within the scope of their professional training and never misrepresent themselves. Confidentiality must be tenaciously protected, and both the clients’ and the providers’ best interests must be guarded.

Wise and prudent health-care employees will select employers for whom they have respect and to whom they can remain loyal. Matching your personal understanding of how to care for clients to that of your employer avoids conflicts at a later time. The majority of health-care professionals have a concern for quality health care, and that concern is often reflected in community efforts and contributions.

Refer to the following Case Law that illustrates a disregard of personal and professional ethics on the part of a medical provider.

Case Law A physician in Lehi, Utah was accused in August 2009 of the following: 1. Fondling his female medical assistant (MA) while pretending to teach her how to diagnose

heart murmurs (Civil Suit) 2. Two counts of forcible sex abuse (Criminal Case) 3. Two counts of voyeurism (Criminal Case) 4. One count of obstruction of justice (Criminal Case)

Dr. Steven Pack also faces an investigation by the Division of Occupational and Professional Licensing.

Dr. Pack allegedly called his 18-year-old MA to an examination room to teach her how to diagnose heart murmurs. He asked her to lie on an examination table, lifted her shirt and bra, and fondled her breasts as he told her he was “feeling” for heart murmurs. Pack allegedly again inappropriately touched the woman while teaching her how to use a heart monitor and elec- trocardiograph machine. The MA became upset and told a nurse practitioner at the office what happened. This civil lawsuit comes 1 day after Lehi police arrested Pack for allegedly recording

Chapter 1 Medical Law, Ethics, and Bioethics

with a concealed digital camera his female patients undressing in an examination room. In August 2010, Judge Samuel McVey sentenced Steven Pack to 1 year in jail without any early release and a second year with global positioning system (GPS) monitoring. Pack’s license to practice was suspended by the Utah Division of Occupational and Professional Licensing. Civil suits brought by the victims were settled before the sentencing, but the civil remedies were not made public.

There are a number of ethical and legal issues in this case. Identify them. Describe the action you might take in a similar situation.

YOU MUST DECIDE

There is no attempt in this book to determine right or wrong for any of the ethical issues in modern medicine. The purpose is to present the law and the facts that are pertinent in the ambulatory health- care setting and to raise some questions for consideration. Most everyone has decided what is right or wrong on the majority of moral issues, but the same distinction in ethics and bioethics is more complex and not so easily identified. This is partly because oflack of accurate knowledge or infor- mation on a particular issue, but accuracy, knowledge, and information are imperative. It is also important to know how and why those opinions have been formed and to look at what is acceptable according to the legal and ethical standards of today. As health professionals, the challenge is to live and act out of respect for oneself and others and to encourage others to do the same. It is important to know what we are to become and how we can become better than we are. Even when our opinions differ from those of the clients we serve, our clients always deserve respect and dignity from us. The hope is that the forthcoming discussions on “Allocation of Scarce Medical Resources,” “Genetic Engineering,” “Reproductive Issues,” “End of Life Issues,” and “Have a Care” will offer a better understanding of what is and what may become.

In reading the following chapters and considering their effect on you personally as well as your role as a health professional, you may find the following lines from a poem by F. A. Russel (1849-1914) helpful.

REMEMBER … Seek the right, perform the true, Raise the work and life anew. Hearts around you sink with care; You can help their load to bear. You can bring inspiring light, Arm their faltering will to fight.

SUMMARY

Knowledge oflaw, ethics, and bioethics is essential for all health-care professionals. The Ethics Check questions offer one approach to address these issues on a personal level. Professional codes of ethics are further guides to performance as a health-care professional. Those who have the professional traits identified in this chapter will be successful health-care employees and will find their profession rewarding and fulfilling. There is no opportunity for boredom in such a fast-paced and rapidly changing field as health care.

TRUE OR FALSE

T F 1. Ethics is a set of moral standards or a code of behavior.

T F 2. Bioethics relates to societal rules or regulations obligatory to observe.

T F 3. Increased numbers of specialists make it more difficult to coordinate client care.

T F 4. National Healthcare Reform of2010 is likely the most historic domestic policy since Medicare was created in 1965.

T F 5. Blanchard and Peale identified a Patient Bill of Rights.

CLASSROOM EXERCISES

1. State in your own words what medical law, ethics, and bioethics mean to you.

2. What is the difference between law and ethics? Can a law be unethical? Can an ethic be unlawful? Justify your response.

3. What would you do if your personal code of ethics does not agree with that of your employer?

phosphoric acid is a triprotic acid with the following pka values

Phosphoric acid is a triprotic acid with the following pKa values:

pka1: 2.148 pka2: 7.198 pka3: 12.375

You wish to prepare 1.000 L of a 0.0100 M phosphate buffer at pH 7.45. To do this, you choose to use mix the two salt forms involved in the second ionization, NaH2PO4 and Na2HPO4, in a 1.000 L volumetric flask and add water to the mark. What mass of each salt will you add to the mixture?

?? grams NaH2PO4
?? grams Na2HPO4

Hint: Use the Henderson-Hasselbalch equation to get the molar ratio of Na2HPO4 to NaH2PO4 required, then the fraction of each form from the ratio. The total moles needed will be 1.000 L × 0.0100 M = 0.0100 moles. Use the formula mass to calculate the mass needed. (FM NaH2PO4 = 119.98; FM Na2HPO4 = 141.96).

I am completely lost on how to solve this problem.

asked by Sam
Feb 22, 2013
pH=pka+log({A-]/[HA])

pH=7.45
pka=12.375

Solve for ratio:

10^(7.45-12.375)={A-]/[HA]=1.19×10^-5

Since you have a total of 0.01 moles,

1.19×10^-5*(0.01moles)= moles of Na2HPO4

0.01 moles-moles of Na2HPO4= moles of NaH2PO4

Use the formula weights to solve for the number for each that Dr. Bob222 gave you.

**** Not sure about that pKa value that I chose.

Use the HH equation to solve for the ratio base/acid.
One equation you need is base/acid.
The other equation you need is
base + acid = 0.01
That two equations in two unknowns; solve for acid concn and base concn and convert to grams. Post your work if you gets stuck.

Setup is correct, but substitute 7.198. That should change 1.19×10^-5 to 1.78 and do what Dr.Bob222 told you to do.

After you get the ratio. From the
0.01 moles-moles of Na2HPO4= moles of NaH2PO4
=> (0.01 – Na2HPO4)/(Na2HPO4) = (ratio of pka2 from hasselbalch)
unit will be mol, convert to g

using general trends, predict the stability of the following nuclei.

A magic number is the name given to certain numbers of protons or neutrons that have a high correlation to stability in nuclei.

Magic # of protons: 2,8,20,28,50,82
Magic # of neutrons: 2,8,20,38,50,82,126, 184

Using general trends, predict the stability of the following nuclei.
Either STABLE or RADIOACTIVE

A)arsenic-82
B)calcium-40
C)radium-233
D)potassium-44
E)zinc-64

(I figured B would be stable because it falls under the magic numbers list. Also I think C would be radioactive because it does not seem to fit with the others)
