单项选择题
A client with a forceful, pounding heartbeat is diagnosed with mitral valve prolapse. This client should avoid which of the following
A．High volumes of fluid intake.
B．Aerobic exercise programs.
C．Caffeine-containing products.
D．Foods rich in protein.
答案
参考答案：C
解析：Caffeine is a stimulant, which can exacerbate palpitations and should be avoided by a client with symptomatic mitral valve prolapse. High-fluid intake helps maintain adequate preload and cardiac output. Aerobic exercise helps increase cardiac output and decrease heart rate. Protein-rich foods aren't restricted but high-calorie foods are.
