【正确答案】 A

【答案解析】The passage of liquid or semiliquid stools results from seepage of unformed bowel contents around the impacted stool in the rectum. Clients with fecal impaction don't pass hard, brown, formed stools because the stool can't move past the impaction. Clients usually report the urge to defecate--although they can't pass stool--and decreased appetite.
