单项选择题
A 72-year-old client seeks help for chronic constipation. This is a common problem for elderly clients due to several factors related to aging. Which of the following is one such factor ？（）
A．Increased intestinal motility.
B．Decreased abdominal strength.
C．Increased intestinal bacteria.
D．Decreased production of hydrochloric acid.
答案
参考答案：B
解析：
Decreased abdominal strength, muscle tone of the intestinal wall, and motility all contribute to chronic constipation in the elderly. A decrease in hydrochloric acid causes a decrease in absorption of iron, and an increase in intestinal bacteria actually causes diarrhea.
