Question 1

Which antiarrhythmic drug requires monitoring of thyroid function due to its iodine content?

Accepted Answer

Amiodarone

Answer

Amiodarone contains iodine and can cause thyroid dysfunction, requiring regular thyroid function monitoring.

Question 2

A cardiac rehab specialist should know that diuretics may cause which electrolyte imbalance that can lead to arrhythmias?

Accepted Answer

Hypokalemia

Answer

Loop and thiazide diuretics can cause hypokalemia, which predisposes patients to dangerous cardiac arrhythmias.

Question 3

When should a cardiac rehab patient be instructed to take sublingual nitroglycerin?

Accepted Answer

At the onset of chest pain or angina

Answer

Sublingual nitroglycerin should be taken at the onset of angina symptoms to rapidly relieve chest pain.

Question 4

Aspirin therapy in cardiac rehabilitation patients functions primarily as which type of agent?

Accepted Answer

Antiplatelet

Answer

Aspirin irreversibly inhibits platelet aggregation, reducing the risk of thrombotic cardiovascular events.

Question 5

Which effect does a beta-blocker have on the target heart rate calculation during cardiac rehabilitation exercise testing?

Accepted Answer

It attenuates the heart rate response, lowering the achieved maximum

Answer

Beta-blockers blunt the heart rate response to exercise, so standard age-predicted maximal heart rate formulas are unreliable for these patients.
