, In 1992, there were 980 deaths in a Midwestern city with a B
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
What level of prevention is a blood pressure screening B
program for high school students who are pregnant?
a. primary
b. secondary
c. tertiary
Mr. Forbes complains of "indigestion" and becomes C
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
When myocardial cells are injured, the function of the A
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
Mr. Forbes is being prepared for open heart surgery A
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.
