A nurse is assisting with the care of a client who has diverticulitis. The nurse notes the following provider prescriptions: a clear liquid diet as tolerated, check stools for occult blood, blood glucose checks every 4 hr, repeat CBC in AM, acetaminophen 650 mg PO every 6 hr PRN, administer IV 0.9 percent sodium chloride at 100 mL/hr, ondansetron 4 to 8 mg IV every 8 hr PRN, hydromorphone 0.5 mg IV every 2 hr PRN, and piperacillin/tazobactam 3.375 g IV STAT then every 6 hr. Which of the following findings should the nurse monitor to evaluate if the client's condition is improving, has not changed, or has declined?

The clinical scenario presents a client with acute diverticulitis receiving antibiotic therapy, intravenous hydration, and bowel rest. To evaluate the effectiveness of these treatments, the nurse must apply knowledge of acute inflammatory processes, gastrointestinal assessment parameters, and opioid medication side effects. Choice A rationale Monitoring leukocytes tracks infection resolution, as the normal range is 4500 to 11000 cells per microliter. Respiratory rates assess for respiratory depression secondary to hydromorphone. Bowel sounds evaluate the return of peristalsis as localized bowel inflammation subsides. Choice B rationale Vital signs and fluid output evaluate systemic perfusion and hydration status rather than the localized intestinal inflammation or specific medication side effects. Normal urine output is 0.5 to 1.5 mL per kilogram per hour. Choice C rationale Client mobility, skin turgor, and sleep patterns reflect overall comfort and fluid status but do not provide objective, specific data regarding the resolution of acute diverticular inflammation or the risk of narcotic-induced hypoventilation. Choice D rationale Diet tolerance, fluid intake, and body weight monitor nutritional advancement and overall fluid balance, but they do not serve as primary indicators for tracking the resolution of an acute bacterial gastrointestinal infection.
