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 - ANSWER B

pale. His wife takes him to the Emergency Department at

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 - ANSWER 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
, 4|Page
c. cell volume will decrease
d. all of the above - ANSWER 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. - ANSWER 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
