Question
A client develops an intestinal obstruction postoperatively. A nasogastric tube is attached to low, intermittent suction with orders to "Irrigate NG tube with sterile saline q1h and prn." The rationale for using sterile saline, as opposed to using sterile water to irrigate the NG tube is:
Options
- AWater will deplete electrolytes resulting in metabolic acidosis.
- BSaline will reduce the risk of severe, colicky abdominal pain during NG irrigation.
- CWater is not isotonic and will increase restlessness and insomnia in the immediate postoperative
- DSaline will increase peristalsis in the bowel.

Explanation
(A) Water is a hypotonic solution and will deplete electrolytes and cause metabolic acidosis when used for nasogastric irrigation. (B) Irrigating with saline does not cause abdominal discomfort. Severe, colicky abdominal pain is a symptom of intestinal obstruction. (C) Irrigating with water will not cause restlessness or insomnia in the postoperative client. Restlessness and insomnia can be emotional complications of surgery. (D) A nasogastric tube placed in the stomach is used to decompress the bowel. Irrigating with saline ensures a patent, well-functioning tube. Irrigating with saline will not increase peristalsis.
