An adolescent client immobilized in a spica cast complains of having trouble breathing after meals. Which of the following actions would be best（）
A. Encourage the client to drink more between meals.
B. Teach the adolescent purse&lip breathing.
C. Give the client a laxative after meals.
D. Offer the client small feedings several times a day.
参考答案：D
解析：
A hip spica cast extends up over the abdomen. Because the abdomen is in a fixed space, abdominal distention secondary to eating pushes the abdominal contents against the diaphragm resulting in decreased chest expansion and subsequent possible respiratory distress. Because the client’s complaints are associated with meals, offering small frequent meals provides nutritional support while minimizing distention.
