QUIZ #1 – CD

Capillary refill time during successful shock resuscitation.

Correct answer: A

Explanation:
CRT is a rapidly responsive bedside marker of peripheral perfusion. Lactate kinetics are slower and are influenced not only by tissue perfusion but also by production, adrenergic stimulation, metabolism, and hepatic clearance. Therefore, peripheral perfusion may improve while lactate remains elevated.
