the end of 1992 for AIDS?
a. 6
b. 25
c. 88
d. 116
Ans: B

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?

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.
