Pharmacological and Parenteral Therapies Q 105

---

The nurse is aware that one 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 blocker

     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-adrenergic blockers work by blocking beta receptors in the myocardium, reducing the response to catecholamines and sympathetic nerve stimulation.

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.
