A client asks the nurse about the purpose of a urine test in the evaluation of appendicitis. What should the nurse explain about the relevance of a urine test in this context?

A) Correct. Rebound tenderness in the lower right abdomen is a hallmark symptom that often occurs in the later stages of appendicitis. It indicates peritoneal irritation and is a sign of potential appendix perforation.

B) Incorrect. While severe, constant abdominal pain in the lower right quadrant is a characteristic symptom of appendicitis, it may occur in both early and later stages.

C) Incorrect. A low-grade fever and elevated white blood cell count are indicative of an inflammatory response and may occur in the later stages of appendicitis, but they are not as specific as rebound tenderness.

D) Incorrect. Diarrhea and frequent bowel movements are not typically associated with appendicitis. Constipation is a more common gastrointestinal symptom in this condition.

A) Incorrect. Having a high-fiber diet rich in fruits and vegetables is generally considered beneficial for digestive health, but it is not a recognized risk factor for appendicitis.

B) Correct. A history of previous episodes of appendicitis is a known risk factor. Once a person has had appendicitis, they are at a higher risk of experiencing it again in the future.

C) Incorrect. Engaging in regular physical exercise and maintaining a healthy weight are positive lifestyle choices but are not considered risk factors for appendicitis.

D) Incorrect. Frequent consumption of spicy foods is not identified as a risk factor for appendicitis.
