A nurse is assisting with the care of a client in the emergency department. The nurse is reviewing the data collected. Which of the following 4 findings can indicate a recurrence of diverticulitis? Select the 4 findings that indicate a recurrence of diverticulitis.

The scenario requires identifying clinical indicators of recurrent colonic inflammation. Knowledge of diverticulitis pathophysiology, systemic inflammatory responses, and localized peritoneal manifestations must be applied to select findings that confirm active acute disease recurrence. Choice A rationale An elevated temperature indicates an active systemic inflammatory or infectious response. Normal body temperature is 36.5 to 37.5 degrees Celsius, and elevations signify the body fighting localized microperforations or diverticular infection. Choice B rationale Acute inflammatory changes stretching the colonic wall stimulate visceral pain receptors, causing severe discomfort. This typically manifests as constant left lower quadrant pain, which is the hallmark indicator of diverticular inflammation. Choice C rationale The timing and content of the last food intake do not indicate active colonic inflammation. This finding provides context for potential diagnostic testing or surgical planning but does not confirm pathological recurrence. Choice D rationale Isolated blood pressure readings are not specific indicators of diverticulitis recurrence. Blood pressure changes typically occur secondary to severe pain, dehydration, or septic shock rather than localized diverticular inflammation itself. Choice E rationale Abdominal findings including localized tenderness, guarding, or rebound tenderness indicate localized peritoneal inflammation. These objective physical assessment pieces directly reflect the anatomical site of active diverticular swelling and tissue irritation. Choice F rationale An elevated heart rate is a non-specific physiological response to pain, anxiety, or fever. While present during illness, tachycardia alone does not specifically identify or differentiate a diverticulitis recurrence from other stressors. Choice G rationale Gastrointestinal manifestations like nausea, vomiting, constipation, or diarrhea occur due to localized colonic inflammation and altered motility. These symptoms directly reflect the functional disruption caused by acute diverticular disease flare-ups..
