A 75-Year-Old Patient Is Received into the Postanesthesia Recovery Room

A 75-year-old patient is received into the postanesthesia recovery room (PACU) following a 6-hour abdominal surgery. The patient's hemodynamic status is stable. Based on knowledge of the patient's surgery and the common postoperative complications the patient might be at risk for, the recovery room nurse would perform which interventions?

A) Keep the room temperature at 70 degrees, consider supplemental oxygen, and provide warm blankets.
B) Consider increasing the IV fluids, assess for urine output, and monitor the oxygen saturation.
C) Assess the patient's blood pressure more frequently than for younger clients and provide oxygen.
D) Provide postoperative instructions to avoid straining and eat a low-fiber diet.
