Test Bank for Porth’s Pathophysiology 10th Edition Norris
1. At an international nursing conference, many discussions and breakout sessions focused
on the World Health Organization (WHO) views on health. Of the following comments
made by nurses during a discussion session, which statements would be considered a
good representation of the WHO definition? Select all that apply.
A) Interests in keeping the elderly population engaged in such activities as book
reviews and word games during social time
B) Increase in the number of chair aerobics classes provided in the skilled care
facilities
C) Interventions geared toward keeping the elderly population diagnosed with
diabetes mellitus under tight blood glucose control by providing in-home cooking
classes
D) Providing transportation for renal dialysis patients to and from their hemodialysis
sessions
E) Providing handwashing teaching sessions to a group of young children
Ans: A, B, C, E
Feedback:
The WHO definition of health is defined as “a state of complete physical, mental, and
social well-being and not merely the absence of disease and infirmity.” Engaging in
book reviews facilitate mental and social well-being; chair aerobics helps facilitate
physical well-being; and assisting with tight control of diabetes helps with facilitating
physical well-being even though the person has a chronic disease. Handwashing is vital
in the prevention of disease and spread of germs.
2. A community health nurse is teaching a group of recent graduates about the large
variety of factors that influence an individual’s health or lack thereof. The nurse is
referring to the Healthy People 2020 report from the U.S. Department of Health and
Human Services as a teaching example. Of the following aspects discussed, which
would be considered a determinant of health that is outside the focus of this report?
A) The client has a diverse background by being of Asian and Native American
descent and practices various alternative therapies to minimize the effects of stress.
B) The client has a family history of cardiovascular disease-related to
hypercholesterolemia and remains non-compliant with the treatment regime.
C) The client has a good career with exceptional preventative health care benefits.
D) The client lives in an affluent, clean, suburban community with access to many
health care facilities.
Ans: B
Feedback:
In Healthy People 2020, the focus is to promote good health to all (such as using
alternative therapies to minimize effects of stress); achieving health equity and
promoting health for all (which includes having good health care benefits); and
promoting good health (which includes living in a clean community with good access to
health care). A client’s noncompliance with treatments to control high cholesterol levels
within the presence of a family history of CV disease does not meet the “attaining lives
free of preventable disease and premature death” determinant.
3. A physician is providing care for a number of patients on a medical unit of a large,
university hospital. The physician is discussing with a colleague the differentiation
between diseases that are caused by abnormal molecules and diseases that cause disease.
Which of the following patients most clearly demonstrates the consequences of
molecules that cause disease?
A) A 31-year-old woman with sickle cell anemia who is receiving a transfusion of
packed red blood cells
B) A 91-year-old woman who has experienced an ischemic stroke resulting from
familial hypercholesterolemia
C) A 19-year-old man with exacerbation of his cystic fibrosis requiring oxygen
therapy and chest physiotherapy
D) A 30-year-old homeless man who has Pneumocystis carinii pneumonia (PCP) and
is HIV positive.
Ans: D
Feedback:
PCP is an example of the effect of a molecule that directly contributes to disease. Sickle
cell anemia, familial hypercholesterolemia, and cystic fibrosis are all examples of the
effects of abnormal molecules.
4. A member of the health care team is researching the etiology and pathogenesis of a
a number of clients who are under his care in a hospital context. Which of the following
aspects of clients’ situations bNesUtRchSaIraNctGerTizBe.s CpaOthMogenesis rather than etiology?
A) A client who has been exposed to the Mycobacterium tuberculosis bacterium
B) A client who has increasing serum ammonia levels due to liver cirrhosis
C) A client who was admitted with the effects of methyl alcohol poisoning
D) A client with multiple skeletal injuries secondary to a motor vehicle accident
Ans: B
Feedback:
Pathogenesis refers to the progressive and evolutionary course of disease, such as the
increasing ammonia levels that accompany liver disease. Bacteria, poisons, and
traumatic injuries are examples of etiologic factors.
5. A new myocardial infarction patient requiring angioplasty and stent placement has
arrived to his first cardiac rehabilitation appointment. In this first session, a review of
the pathogenesis of coronary artery disease is addressed. Which statement by the patient
verifies to the nurse that he has understood the nurse’s teachings about coronary artery
disease?
A) “All I have to do is stop smoking, and then I won’t have any more heart attacks.”
B) “My artery was clogged by fat, so I will need to stop eating fatty foods like
French fries every day.”
C) “Sounds like this began because of inflammation inside my artery that made it
easy to form fatty streaks, which lead to my clogged artery.”
D) “If I do not exercise regularly to get my heart rate up, blood pools in the veins
causing a clot that stops blood flow to the muscle, and I will have a heart attack.”
Ans: C
Feedback:
The true etiology/cause of coronary artery disease (CAD) is unknown; however, the
pathogenesis of the disorder relates to the progression of the inflammatory process from
a fatty streak to the occlusive vessel lesion seen in people with coronary artery disease.
Risk factors for CAD revolve around cigarette smoking, diet high in fat, and lack of
exercise.
6. A 77-year-old man is a hospital inpatient admitted for exacerbation of his chronic
obstructive pulmonary disease (COPD), and a respiratory therapist (RT) is assessing the
client for the first time. WhichNUofRtSheIfNolGloTwBin.gCaOspMects of the patient’s current state of health would be best characterized as a symptom rather than a sign?
A) The patient’s oxygen saturation is 83% by pulse oxymetry.
B) The patient notes that he has increased work of breathing when lying supine.
C) The RT hears diminished breath sounds to the patient’s lower lung fields
bilaterally.
D) The patient’s respiratory rate is 31 breaths/minute.
Ans: B
Feedback:
Symptoms are subjective complaints by the person experiencing the health problem,
such as complaints of breathing difficulty. Oxygen levels, listening to breath sounds,
and respiratory rate is all objective, observable signs of disease.
7. Which of the following situations would be classified as a complication of a disease or
outcome from the treatment regimen? Select all that apply.
A) Massive pulmonary emboli following diagnosis of new-onset atrial fibrillation
B) Burning, intense incision pain following surgery to remove a portion of colon due
to intestinal aganglionosis
C) Development of pulmonary fibrosis following treatment with bleomycin, an
antibiotic chemotherapy agent used in treatment of lymphoma
D) Gradual deterioration in ability to walk unassisted for a patient diagnosed with
Parkinson disease
E) Loss of short-term memory in a patient diagnosed with Alzheimer disease
Ans: A, C
Feedback:
Development of pulmonary emboli and pulmonary fibrosis following chemotherapy are
both examples of a complication (adverse extensions of a disease or outcome from
treatment). It is normal to expect incisional pain following surgery. As Parkinson
disease progresses, the inability to walk independently is expected. This is a normal
progression for people diagnosed with Parkinson’s. Loss of short-term memory in a
patient diagnosed with Alzheimer disease is an expected finding.
8. Laboratory testing is ordered for a male patient during a clinic visit for a routine
follow-up assessment of hypertension. When interpreting lab values, the nurse knows
that
A) a normal value represenNtsUtRheStIesNtGreTsuBl.tsCthOaMt fall within the bell curve.
B) if the lab result is above the 50% distribution, the result is considered elevated.
C) all lab values are adjusted for gender and weight.
D) if the result of a very sensitive test is negative, that does not mean the person is
disease free.
Ans: A
Feedback:
What is termed a normal value for a laboratory test is established statistically from
results obtained from a selected sample of people. A normal value represents the test
results that fall within the bell curve or the 95% distribution. Some lab values (like
hemoglobin) are adjusted for gender, other comorbidities, or age. If the result of a very
sensitive test is negative, it tells us the person does not have the disease, and the disease
has been ruled out or excluded.
9. The laboratory technologists are discussing a new blood test that helps establish a
differential diagnosis between shortness of breath with a cardiac etiology and shortness
of breath with a respiratory/pulmonary etiology. A positive result is purported to
indicate a cardiac etiology. The marketers of the test report that 99.8% of patients who
have confirmed cardiac etiologies test positive in the test. However, 1.3% of patients
who do not have cardiac etiologies for their shortness of breath also test positive. Which
of the following statements best characterizes this blood test?
A) Low validity; high reliability
B) High sensitivity; low specificity
C) High specificity; low reliability
D) High sensitivity; low reliability
Ans: B
Feedback:
A large number of patients would receive the correct positive diagnosis (high
sensitivity), while a significant number would receive a false-positive diagnosis (low
specificity). The information given does not indicate low reliability or low validity.
10. As part of a screening program for prostate cancer, men at a senior citizens’ center are
having their blood levels of prostate-specific antigen (PSA) measured. Which of the
following statements would best characterize a high positive predictive value but a low
negative predictive value for this screening test?
A) All of the men who had high PSA levels developed prostate cancer; several men
who had low PSA levelNsUalRsoSdIeNveGloTpBe.dCprOoMstate cancer.
B) All of the men who had low PSA levels were cancer-free; several men who had
high levels also remained free of prostate cancer.
C) Men who had low PSA levels also displayed false-positive results for prostate
cancer; men with high levels were often falsely diagnosed with prostate cancer.
D) The test displayed low sensitivity but high specificity.
Ans: A
Feedback:
The test’s inability to rule out cancer with a low PSA level indicates a low negative
predictive value. Answer B suggests a high negative predictive value, while answer C
indicates a low positive predictive value. High positive predictive value is associated
with high sensitivity.
