Administration of a vasodilator to a patient in shock would be expected to
A) decrease vascular resistance.
B) increase contractility.
C) decrease left ventricular afterload.
D) increase tissue perfusion.

Question

Quizplus · Accepted Answer

Vasodilators are used to decrease the workload of the heart by decreasing left ventricular afterload.Nitroprusside and nitroglycerin are examples of vasodilators.Dobutamine is used to decrease vascular resistance.Positive inotropic drugs are used to increase contractility.Positive inotropes include b-adrenergic agonists,which have the ability to increase tissue perfusion.
