A nurse is planning education for a client who is prescribed heparin. Which statement should the nurse plan to include in the teaching?

A. Increases cardiac output: Dobutamine is a beta-1 adrenergic agonist that primarily increases the strength of myocardial contractions, leading to enhanced cardiac output. It is commonly used in clients with heart failure or cardiogenic shock to improve tissue perfusion without significantly increasing heart rate.

B. Promotes diuresis: Dobutamine does not have a direct diuretic effect. While improved cardiac output may indirectly enhance renal perfusion and urine output, promoting diuresis is not its primary therapeutic action.

C. Increases blood pressure: Dobutamine may slightly increase systolic blood pressure due to improved cardiac output, but it is not primarily used as an antihypotensive agent. Its main role is enhancing myocardial contractility rather than raising blood pressure.

D. Inhibits platelet aggregation: Dobutamine has no effect on platelet function or aggregation. Its mechanism of action is limited to stimulating beta-1 receptors in the heart to improve contractility.

A. Controlled blood glucose: Verapamil is a calcium channel blocker and does not affect glucose metabolism. It has no role in managing diabetes or controlling blood glucose levels.

B. Enhanced cognitive function: Verapamil does not improve cognition or memory. Its pharmacologic action is focused on the cardiovascular system rather than the central nervous system.

C. Increased muscle strength: Verapamil does not influence skeletal muscle strength. Its mechanism targets smooth and cardiac muscle by inhibiting calcium influx, primarily affecting vascular tone and heart contractility.

D. Decreased blood pressure: Verapamil causes vasodilation by blocking calcium channels in vascular smooth muscle, which reduces systemic vascular resistance and lowers blood pressure. It is used therapeutically to manage hypertension and certain cardiac arrhythmias.
