Quiz About CA Channel Blockers

1. True or False: Calcium channel blockers combined with beta blockers can cause significant hypotension and/or bradycardia.

True

False

They both lower blood pressure - and heart rate. If given together, they may produce twice the results.

Hypotension

Hypertension

Bradycardia

AV block

Signs of toxicity include hypotension, AV block, bradycardia, signs of decreased cardiac output, nausea, and generalized weakness.

6. Which of the following is NOT accomplished by calcium channel blockers?

Increased myocardial oxygen supply

Dilated coronary arteries

Increased vascular resistance

Decreased oxygen demand

Calcium channel blockers increase myocardial oxygen supply by dilating the coronary arteries. They decrease vascular resistance and decrease oxygen demand.

7. True or False: You should withhold a calcium channel blocker if the heart rate is below 70bpm.

True

False

Withhold calcium channel blockers if the heart rate is below 50 bpm.

8. True or False: Calcium channel blockers can be used to prevent an acute angina attack.

True

False

Calcium channel blockers are not effective in an acute angina attack. Use a fast-acting nitrate in that situation.
