MULTIPLE CHOICE

1. Which medication combinations may be beneficial in treating angina pectoris?
a.
Antidysrhythmics and platelet active agents
b.
ACE inhibitors and statins
c.
Vasoconstrictors and diuretics
d.
Analgesics and thrombolytics

ANS: B
ACE inhibitors and statins are often combined to treat angina pectoris. Antidysrhythmics and platelet active agents are not used in combination to treat angina because angina does not typically result in rhythm disturbances. Vasoconstrictors would exacerbate angina and are not used with diuretics. Analgesics and thrombolytics are not used in combination to treat angina because angina is not caused by a clot, so thrombolytics are not necessary.

2. A patient has been diagnosed with angina pectoris and an elevated LDL cholesterol level. The health care provider has prescribed HMG CoA reductase inhibitor. What is the primary indication in using this medication?
a.
Reduce coronary vessel spasm.
b.
Simplify oxygen requirements of the cardiac cells.
c.
Lower cholesterol levels.
d.
Dilate the coronary arteries.

ANS: C
HMG CoA reductase inhibitor, a statin, has become standard therapy to be used with elevated cholesterol levels. This medication prevents added atherosclerotic vessel build up and further narrowing of the coronary arteries. Statins do not affect vascular spasms or oxygen requirements of cells. Statins do not dilate coronary arteries.
