Which measure is optimal in order to prevent abdominal distention following a cesarean birth?
Correct Answer: C
Rationale: The correct answer is C: Early and frequent ambulation. This measure is optimal to prevent abdominal distention following a cesarean birth because it helps promote bowel motility and gas expulsion. Ambulation stimulates peristalsis, preventing gas accumulation and reducing the risk of distention. Rectal suppositories (A) may help with constipation but do not address the root cause of distention. Carbonated beverages (B) can exacerbate bloating and gas production. Tightening and relaxing abdominal muscles (D) may provide some relief but are not as effective as promoting ambulation for preventing abdominal distention.
