A nurse is caring for a client who is 2 days postoperative from abdominal surgery. The client reports discomfort from abdominal distension and flatus. Which of the following suggestions should the nurse include?

A. Drink cold liquids.: Cold fluids may increase gastric spasms and are not effective in reducing gas. B. Assume position with legs and rectum lower than the stomach.: This positioning does not relieve flatus or distension and may worsen discomfort. C. Use a straw.: Using a straw increases swallowed air, worsening gas and abdominal distension. D. Ambulate several times a day.: Ambulation promotes peristalsis, reduces gas buildup, and relieves postoperative abdominal distension.
