What is the measurement of the systemic vascular resistance?

Cardiac beat pressure
Diastolic blood pressure
Systemic blood pressure
Arterial pressure

Explanation

Answer: B - The measurement of the systemic vascular resistance is the diastolic blood pressure. The narrow pulse pressure (systolic minus the diastolic) and pale, cool, clammy skin are indicative of peripheral vasoconstriction, which causes an increased systemic vascular resistance. These signs results from a decreased perfusion of peripheral skin and subcutaneous tissue.
