Mean arterial pressure can be increased by all of the following EXCEPT

Question

Quizplus · Accepted Answer

Mean arterial pressure (MAP) is determined by cardiac output and systemic vascular resistance. Increasing venous return, blood volume, heart rate, and sympathetic activity all contribute to an increase in cardiac output or systemic vascular resistance, thus increasing MAP. Decreasing end-diastolic volume, however, would reduce the stroke volume (due to the Frank-Starling mechanism), leading to a decrease in cardiac output and potentially lowering MAP, making it the correct exception.
