CCRP CCRP Pharmacology 1 — Questions and Answers
Question 1: Which class of medications is most commonly used to reduce heart rate and myocardial oxygen demand in cardiac rehabilitation patients?
- Beta-blockers (Correct answer)
- ACE inhibitors
- Calcium channel blockers
- Nitrates
Correct answer: Beta-blockers
Beta-blockers reduce heart rate and myocardial oxygen demand, making them a cornerstone therapy in cardiac rehabilitation.
Question 2: A cardiac rehab patient on warfarin should be monitored for which of the following during exercise?
- Hypoglycemia
- Excessive bleeding risk from minor injuries (Correct answer)
- Bronchospasm
- Renal impairment
Correct answer: Excessive bleeding risk from minor injuries
Warfarin is an anticoagulant that increases bleeding risk, so minor injuries during exercise require careful monitoring.
Question 3: Which medication class lowers LDL cholesterol by inhibiting HMG-CoA reductase and is commonly prescribed to cardiac rehab patients?
- Fibrates
- Statins (Correct answer)
- Bile acid sequestrants
- Niacin
Correct answer: Statins
Statins inhibit HMG-CoA reductase, reducing LDL cholesterol and cardiovascular risk in cardiac patients.
Question 4: Nitroglycerin is prescribed to cardiac rehab patients primarily to treat which condition?
- Hypertension
- Angina pectoris (Correct answer)
- Heart failure
- Arrhythmia
Correct answer: Angina pectoris
Nitroglycerin dilates coronary vessels to relieve angina pectoris by reducing myocardial oxygen demand.
Question 5: A patient taking an ACE inhibitor in cardiac rehab may develop which notable side effect that should be documented?
- Bradycardia
- Persistent dry cough (Correct answer)
- Hyperkalemia only
- Edema
Correct answer: Persistent dry cough
ACE inhibitors commonly cause a persistent dry cough due to increased bradykinin levels.
Question 6: Digoxin is used in cardiac rehab patients primarily for which purpose?
- Pain management
- Rate control in atrial fibrillation and heart failure management (Correct answer)
- Anticoagulation
- Blood pressure reduction
Correct answer: Rate control in atrial fibrillation and heart failure management
Digoxin slows the ventricular rate in atrial fibrillation and increases myocardial contractility in heart failure.
