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 number of clients who are under his care in a hospital context. Which of the
following aspects of clients' situations best characterizes pathogenesis 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
dr.j
,TEST BANK PORTH'S ESSENTIALS OF
PATHOPHYSIOLOGY 5TH EDITION
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. Which of the following aspects 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 are 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 represents the test results that 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
