The nurse applies pressure over an area of the lower abdomen where the client reports pain. The client denies pain upon palpation but reports pain when the pressure is released. Which action should the nurse implement?

A. Distraction and relaxation techniques may help manage general discomfort but are not appropriate when a specific physical finding, such as rebound tenderness, indicates a potential acute abdominal condition. B. Catheterizing the bladder is not related to the finding of rebound tenderness, which is more likely indicative of an underlying condition such as appendicitis or peritonitis. C. Rebound tenderness is a significant finding that can indicate peritoneal irritation, such as from appendicitis. The healthcare provider should be notified immediately so that further diagnostic evaluation and appropriate treatment can be initiated. D. Administering a laxative without further assessment could exacerbate the condition if the underlying cause is an acute abdominal process, such as appendicitis, which requires surgical intervention rather than bowel stimulation.
