If a patient's peripheral arteries constrict due to hypothermia, which consequence follows regarding mean arterial pressure?

💡 Explanation

Peripheral artery constriction increases total peripheral resistance (TPR). Because mean arterial pressure (MAP) is the product of cardiac output and TPR, the MAP increases. Therefore, the correct answer is that it will increase due to TPR increase, rather than a primary change in cardiac output or stroke volume.
