1,000 people contract the disease yearly. The population of the country is
4,500,000. Which of the following statements is correct?
a. The prevalence of the disease is 10% and the incidence is .02%.
b. The prevalence of the disease is .02% and the incidence is 10%.
c. Neither is correct.
d. There is insufficient data >CORRECT ANS>>A
In relation to disease development, the term "etiology" refers to which of the
following?
a. number of people with the disease
b. cause of the disease
c. definition of the disease
d. outcome of the disease >CORRECT ANS>>B
Which of the following is(are) true about "symptoms"?

In 1992, there were 980 deaths in a Midwestern city with a population of
1,000,000. At the beginning of that year, 900 cases of AIDS existed in this
,population. During the year, 250 new cases of AIDS were diagnosed, and 75
people died of the disease in 1992.
Using the data given above, what was the incidence rate (per 100,000
population) at the end of 1992 for AIDS?
a. 6
b. 25
c. 88
d. 116 >CORRECT ANS>>B
What level of prevention is a blood pressure screening program for high
school students who are pregnant?
a. primary
b. secondary
c. tertiary >CORRECT ANS>>B
Mr. Forbes complains of "indigestion" and becomes sweaty and pale. His wife
takes him to the Emergency Department at Northwestern Memorial Hospital.
A cardiac catheterization 2 days later shows partial blockage of his right
coronary artery (RCA).
Blockage of the right coronary artery can lead to myocardial cell injury
because it results in which of the following?
a. bilirubin accumulation in myocardial cells
b. alteration in the genetic material of myocardial cells
c. reduced energy production in myocardial cells
d. activation of the complement system >CORRECT ANS>>C
When myocardial cells are injured, the function of the Na-K membrane pump
may be impaired. Which of the following may then result?
a. intracellular sodium will increase
,b. extracellular potassium will decrease
c. cell volume will decrease
d. all of the above >CORRECT ANS>>A
Mr. Forbes is being prepared for open heart surgery when he suffers a
myocardial infarction in which a large part of his left ventricle has suffered
lethal cell injury.
Mr. Forbes' CPK-MB and LDH1, enzymes associated with myocardial cells,
are significantly elevated. What is the best explanation for this?
a. It is a sign that necrotic myocardial cells have released their
cytoplasmic contents into the blood.
b. It is a sign of reversible fatty accumulation in the myocardial cells
c. It is a sign that the myocardial cells are undergoing hypertrophy.
d. None of the above. >CORRECT ANS>>A
If a tissue specimen of myocardial cells were obtained for examination from
Mr. Forbes, which of the following findings would indicate irreversible cell
injury?
a. cellular swelling
b. decreased ATP production
c. decreased intracellular calcium
d. dissolution of nuclear material >CORRECT ANS>>D
The accumulation of lactic acid that occurs with impaired energy production
results from which of the following?
a. increased intracellular glucose
b. increased anaerobic metabolism
, c. decreased metabolic rate
d. increased oxidative phosphorylation >CORRECT ANS>>B
A mountain climber is stranded at 23,000 feet in the Swiss Alps and has lost
all his equipment and supplies in an avalanche. Subsequently, he suffers cell
injury due to impaired ATP production. The reason for the decrease in ATP is
which of the following?
a. enzyme inhibition
b. uncoupling
c. hypoxia
d. none of the above >CORRECT ANS>>C
An elderly patient develops an obstruction in his left middle cerebral artery.
The brain tissue supplied by this artery becomes hypoxic. The best
explanation for this is which of the following?
a. the obstruction results in decreased blood flow
b. the obstruction results in decreased hemoglobin in the blood
c. while blood flow stays the same, the obstruction reduces oxygen
content in the blood
d. none of the above explain the reason for the hypoxia >CORRECT
ANS>>A
Increased mobilization and delivery of free fatty acids to liver cells can result
in fat accumulation. Which of the following problems results in increased
mobilization of free fatty acids?
a. anemia
b. hepatic toxins
c. starvation
d. hypoxia >CORRECT ANS>>C
