Correct Answer is A

Explanation

A. Shivering is a common response to cold therapy (such as a hypothermia blanket) as the body attempts to maintain its core temperature. This can increase metabolic demands and oxygen consumption, which should be closely monitored.
B. Seizures are not typically associated with the use of hypothermia blankets unless there are underlying conditions that predispose to them.
C. Dehydration could occur with any prolonged therapy but is not the immediate concern with hypothermia blankets.
D. Burns are rare but could occur if the hypothermia blanket is not properly managed. Shivering is a more immediate concern.

A. Regulation of constriction and dilation of blood vessels in the brain B. Regulation of catecholamines circulating throughout the body C. Regulation of the amount of carbon dioxide exhaled D. Regulation of how much blood is pumped from the heart

Correct Answer is A

Explanation

A. The constriction and dilation of blood vessels in the brain helps maintain appropriate cerebral blood flow and cerebral perfusion pressure (CPP) despite fluctuations in blood pressure.
B. Catecholamines regulate other systemic body functions, but they do not directly impact cerebral perfusion pressure.
C. Carbon dioxide exhalation can affect blood flow, but the primary regulation of CPP is through blood vessel constriction and dilation.
D. The amount of blood pumped from the heart can impact overall blood pressure but does not directly regulate cerebral perfusion pressure.
