单选题 A client is hospitalized with a diagnosis of chronic renal failure. An arteriovenous fistula was created in his left arm for hemodialysis. When preparing the client for discharge, the nurse should reinforce which dietary instruction?
A. "Be sure to eat meat at every meal. "
B. "Monitor your fruit intake and eat plenty of bananas. "
C. "Restrict your salt intake. "
D. "Drink plenty of fluids. /

【正确答案】 C

【答案解析】In a client with chronic renal failure, unrestricted intake of sodium, protein, potassium, and fluids may lead to a dangerous accumulation of electrolytes and protein metabolic products, such as amino acids and ammonia. Therefore, the client must limit his intake of sodium, meat (high in protein), bananas (high in potassium), and fluid because the kidneys can't secrete adequate urine.
