Which of the following classes of medications maximizes cardiac performance in clients with heart failure by increasing ventricular contractility?
A. Beta-adrenergic blockers
B. Calcium channel blockers
C. Diuretics
D. Inotropic agents
Correct Answer: D. Inotropic agents
Inotropic agents are administered to increase the force of the heart’s contractions, thereby increasing ventricular contractility and ultimately increasing cardiac output.
Option A: Beta blockers work by blocking the effects of the hormone epinephrine, also known as adrenaline. They cause the heart to beat more slowly and with less force, which lowers blood pressure.
Option B: Calcium channel blockers decrease the heart rate and ultimately decrease the workload of the heart.
Option C: Diuretics are administered to decrease the overall vascular volume, also decreasing the workload of the heart.
