A patient with a severe burn is at risk of developing hypovolemic shock. Which mechanism maintains blood pressure in shock?
Q1. A patient with a severe burn is at risk of developing hypovolemic shock. Which mechanism maintains blood pressure in shock?
Answer: Baroreceptor-mediated vasoconstriction
Explanation: Baroreceptor-mediated vasoconstriction fails in hypovolemic shock due to decreased venous return. USAT, HAT and MDCAT analytical sections repeat this pattern.
