The nurse assesses a client with lower abdominal pain who reports localized tenderness in the right lower quadrant. Which assessment should the nurse conduct next?

A. Palpating McBurney's point for rebound tenderness helps evaluate for appendicitis, which is relevant given the client’s localized tenderness in the right lower quadrant. B. Murphy's sign is used to assess for gallbladder inflammation, which is not indicated by right lower quadrant pain. C. The Tinel sign is used to assess for nerve irritation, not abdominal pain or appendicitis. D. Testing for a fluid wave is used to assess for ascites, which does not fit the presentation of localized right lower quadrant pain.
