An older client is admitted for repair of a broken hip. To reduce the risk for infection in the postoperative period, which nursing interventions should the nurse include in the client's plan of care? Select all that apply.

Rationale: A. Teach client to use incentive spirometer every 2 hours while awake: Using the incentive spirometer promotes lung expansion and helps prevent postoperative pulmonary infections like pneumonia, which are common in older adults after surgery. B. Assess pain level and medicate PRN as prescribed: Pain management is essential for recovery but does not directly reduce infection risk. While adequate pain control may support deep breathing and mobility, it is not itself an infection-prevention intervention. C. Maintain sequential compression devices while in bed: Sequential compression devices help prevent deep vein thrombosis but do not directly reduce the risk of infection. They serve a circulatory, not an antimicrobial, purpose. D. Remove urinary catheter as soon as possible and encourage voiding: Early catheter removal minimizes the risk of catheter-associated urinary tract infections (CAUTIs), which are a major source of healthcare-associated infections in postoperative patients. E. Administer low molecular weight heparin as prescribed: This medication is used to prevent blood clots, not infection. While important in postoperative care, it does not address infection control directly.
