CCB Quiz: Can You Master The -dipines?

1. Which calcium channel blocker is preferred in a hypertensive patient with concurrent migraine headaches?

Nifedipine

Verapamil

Amlodipine

Isradipine

2. The primary advantage of using calcium channel blockers in angina pectoris is:

Increased myocardial oxygen demand

Decreased coronary vasodilation

Reduced myocardial oxygen demand and improved coronary blood flow

Increased heart rate and contractility

3. A patient on calcium channel blocker therapy for hypertension becomes pregnant. Which action should the nurse recommend?

Continue the current calcium channel blocker safely

Immediately discontinue without medical guidance

Contact the provider for medication review and possible adjustment

Double the dose for better BP control during pregnancy

4. Which calcium channel blocker has the longest half-life and allows once-daily dosing for better compliance?

Immediate-release nifedipine

Amlodipine

Verapamil immediate-release

Diltiazem immediate-release

5. A patient on verapamil reports severe bradycardia. The nurse should prepare for which potential intervention?

Immediate calcium gluconate administration

Atropine or pacing if symptomatic

Increase the verapamil dose

Administer a dihydropyridine agent

6. Nifedipine extended-release is preferred over immediate-release formulations for chronic hypertension primarily because it:

Prevents reflex tachycardia and provides more stable BP control

Has fewer drug interactions

Does not cause peripheral edema

Improves renal function

7. Which patient population requires the most careful monitoring when initiating calcium channel blockers?

Patients with hypertension only

Elderly patients and those with hepatic impairment

Patients on aspirin therapy

Patients with a history of migraines

8. A patient's blood pressure is well-controlled on amlodipine monotherapy. Which assessment indicates the drug is working as intended?

Increased heart rate and decreased peripheral vascular resistance

Decreased systolic/diastolic BP with stable heart rate

Increased cardiac contractility

Enhanced AV node conduction velocity

9. Diltiazem and verapamil should be used cautiously in combination with which antiarrhythmic class?

Class I agents

Class II agents (beta-blockers)

Class III agents

Class IV agents

10. A nurse assesses a patient on calcium channel blocker therapy. Which finding would warrant immediate notification of the provider?

Heart rate of 55 bpm with symptoms of dizziness

Mild ankle edema

Slight headache

Constipation for 2 days

11. Which of the following best describes the mechanism of action of calcium channel blockers?

Inhibit L-type calcium influx into cardiac and vascular smooth muscle cells

Block sodium channels in the cardiac conduction system

Inhibit the sympathetic nervous system directly

Prevent potassium efflux from myocardial cells

12. A patient taking nifedipine for hypertension develops reflex tachycardia. Which additional medication might be prescribed to counteract this effect?

Another dihydropyridine

A beta-blocker

An ACE inhibitor

A thiazide diuretic

13. Grapefruit juice significantly increases serum levels of certain calcium channel blockers. Which mechanism explains this interaction?

Increased renal clearance of the drug

Inhibition of CYP3A4 enzyme in the intestinal wall

Enhanced protein binding in plasma

Decreased gastric pH affecting absorption

14. A patient on diltiazem reports constipation. Which nursing intervention is most appropriate?

Discontinue the medication immediately

Increase fluid intake, dietary fiber, and monitor bowel movements

Switch to a dihydropyridine calcium channel blocker

Administer a laxative without consulting the provider

15. Which calcium channel blocker is contraindicated in a patient with acute decompensated heart failure and reduced ejection fraction?

Amlodipine

Verapamil

Diltiazem

Felodipine

16. A patient develops peripheral edema after starting amlodipine. What is the most likely cause?

Pulmonary edema from negative inotropic effects

Fluid retention from renal dysfunction

Vasodilation causing fluid extravasation into tissues

Hyperaldosteronism induced by the drug

17. Which non-dihydropyridine calcium channel blocker is most commonly used to control ventricular rate in atrial fibrillation?

Diltiazem

Amlodipine

Felodipine

Isradipine

18. A patient taking verapamil reports dizziness and fatigue. Which adverse effect is most likely responsible?

Hypertensive crisis

Negative inotropic and chronotropic effects

Acute coronary syndrome

Severe hyperkalemia

19. Nifedipine is classified as a dihydropyridine calcium channel blocker. Which effect predominates with this drug class?

Negative inotropic effect

Vasodilation and reduced peripheral vascular resistance

Slowed AV node conduction

Increased heart rate and contractility
