A．hypoglycemia.
B．fluid volume excess.
C．aspiration.
D．constipation.

参考答案：C

Of the choices listed, aspiration is the most serious potential complication of tube feedings. Dehydration--not fluid volume excess--is a concern because of decreased free water intake. Hyperglycemia, not hypoglycemia, is a complication secondary to carbohydrate load of enterat feeding solutions. Constipation is a problem, but it usually isn't a serious one. The client would most likely experience diarrhea.
