A nurse is caring for a client who is 1 day postoperative following a laparoscopic hysterectomy and is reporting nausea and abdominal pain. Which of the following actions should the nurse take first?

Choice A reason: Ambulation promotes peristalsis and reduces postoperative complications, but it should not be encouraged before assessing the underlying cause of nausea and pain. Without assessment, ambulation could worsen discomfort or mask complications. Choice B reason: Inserting an NG tube is an invasive intervention reserved for confirmed cases of bowel obstruction or severe ileus. Performing this without assessment risks unnecessary trauma and patient distress. Choice C reason: Auscultating for bowel sounds is the priority because it provides critical information about gastrointestinal motility and potential complications such as ileus or obstruction. Assessment must precede interventions to ensure safety and appropriateness of care. Choice D reason: Administering an antiemetic addresses symptoms but not the underlying cause. Symptom relief without assessment could delay recognition of serious complications.
