b. alteration in the genetic material of myocardial cells
c. reduced energy production in myocardial cells
d. activation of the complement system - ✔ ANSWER ✔ C

membrane pump may be impaired. Which of the following
may then result?

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?
