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 - 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
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.
