单项选择题
A client with chronic obstructive pulmonary disease (COPD) and cor pulmonale is being prepared for discharge. The nurse should provide which instructions
A．"Weigh yourself daily and report a loss of 1 lb in 1 day. "
B．"Eat a high-sodium diet. "
C．"Weigh yourself daily and report a gain of 2 lb in 1 day. "
D．"Maintain bedrest. "
答案
参考答案：C
解析：COPD causes pulmonary hypertension, leading to right ventricular failure or cor pulmonale. The resultant venous congestion causes dependent edema. A weight gain may further stress the respiratory system and worsen the client's condition. He should eat a low-sodium diet to avoid fluid retention and should engage in moderate exercise to avoid muscle atrophy.
