B．Encourage rhythmic breathing exercise.
C．Administer metoclopramide (Reglan) and dexamethasone (Decadron) as prescribed.
D．Withhold fluids for the first 4 to 6 hours after chemotherapy administration.
答案
参考答案：C
解析：Administration of an antiemetic, such as metoclopramide, and an anti-inflammatory, such as dexamethasone, can reduce the severity of chemotherapy-induced nausea and vomiting. This in turn, helps prevent dehydration, a common complication of chemotherapy. The remaining options are unlikely to be as successful' in achieving this outcome.
