The critical care nurse is preparing to initiate an infusion of a vasoactive medication to a patient in shock. The nurse knows that vasoactive medications are given in all forms of shock. What is the primary goal of this aspect of treatment?

Question

A) To prevent the formation of infarcts of emboli
B) To limit stroke volume and cardiac output
C) To prevent pulmonary and peripheral edema
D) To maintain adequate mean arterial pressure

Answer 1

Ans: D
Feedback:
Vasoactive medications can be administered in all forms of shock to improve the patient's hemodynamic stability when fluid therapy alone cannot maintain adequate MAP. Specific medications are selected to correct the particular hemodynamic alteration that is impeding cardiac output. These medications help increase the strength of myocardial contractility, regulate the heart rate, reduce myocardial resistance, and initiate vasoconstriction. They are not specifically used to prevent emboli, edema, or infarcts.
