A nurse is caring for a 58-year-old client who underwent a radical nephrectomy for renal cell carcinoma 24 hours ago. The client has a large abdominal incision with surgical drains in place. Which nursing intervention is the priority during the immediate postoperative period?

Monitoring respiratory status and encouraging deep breathing exercises is the priority due to the risk of respiratory complications like atelectasis or pneumothorax from the surgical site's proximity to the diaphragm. Other interventions are important but secondary to preventing life-threatening respiratory failure.

Postoperative Priority Setting After Radical Nephrectomy

The immediate postoperative period following a radical nephrectomy presents a clinical landscape where the nurse must differentiate between routine surveillance and a life-threatening emergency. The priority intervention is to monitor respiratory status and encourage deep breathing exercises.

Physiological Rationale: The Airway-First Imperative
A radical nephrectomy, particularly when performed via an open approach as described in the provided research, involves a large, upper abdominal incision close to the diaphragm. The primary pathophysiological threat in the first 24 hours is not infection or thromboembolism, but atelectasis and pneumonia. The surgical trauma and pain cause reflexive, shallow "splinting" respirations, which prevent full lung expansion. This leads to alveolar collapse, impaired gas exchange, and hypoxemia. The clinical significance of this is underscored by the analgesic studies provided. Ladjevic et al. ^[1] specifically investigated patients undergoing "open radical nephrectomy" and focused on postoperative pain intensity as a primary outcome. Uncontrolled pain directly inhibits deep breathing and coughing, creating a cycle of hypoventilation and pulmonary complication. By proactively assessing respiratory rate, depth, breath sounds, and oxygen saturation, and coaching the client through incentive spirometry or deep breathing, the nurse directly intervenes to maintain airway patency and alveolar ventilation, which aligns with the "Airway and Breathing" components of the ABC (Airway, Breathing, Circulation) priority framework.

Clinical Reasoning and Sequencing of Care
While the remaining options represent essential components of postoperative care, their urgency is secondary to respiratory compromise in the immediate 24-hour window.
- Monitoring urine output is critical for assessing renal function in the remaining kidney, but a decrease in output over a 2-hour period signals a developing acute kidney injury, which is not an immediately fatal event like a respiratory arrest.
- Assessing the surgical incision for infection is vital, but the clinical signs of infection (redness, purulent drainage, fever) typically manifest after 24 to 72 hours, making this a lower priority in the immediate phase.
- Encouraging early ambulation is a key intervention to prevent deep vein thrombosis and ileus; however, safe ambulation is contingent on a stable respiratory and hemodynamic status. A client with significant atelectasis may become dangerously hypoxic with exertion.

The research context reinforces this prioritization. The study by Zhang et al. on analgesic efficacy in laparoscopic renal surgery highlights the goal of reducing opioid consumption to enhance "recovery outcomes," a core component of which is the ability to breathe deeply and mobilize secretions without excessive sedation or pain. The nurse's role is to integrate this principle by using pain assessment to facilitate, not hinder, pulmonary toilet. Therefore, the nurse's immediate focus must be on ensuring that the client can effectively ventilate and oxygenate, as this forms the foundation upon which all other recovery activities depend.
