Correct Answer: D

Rationale: The correct answer is D: Assessing for symptoms of peritonitis. This intervention is crucial in managing a client with appendicitis because it indicates a possible rupture of the inflamed appendix.

Prompt recognition of these symptoms is essential for timely intervention and surgical management. Choices A, B, and C are incorrect because while assessing for pain is important, assessing for symptoms of peritonitis takes precedence due to the critical nature of appendicitis. Encouraging oral intake of clear fluids and providing discharge teaching are not immediate priorities in the management of a client with acute appendicitis.
