What are common postoperative pulmonary complications and strategies to prevent atelectasis and pneumonia?

• A. Atelectasis is the only concern; prevention includes deep breathing and incentive spirometry.
• B. Pulmonary edema is most common; prevention includes early ambulation only.
• C. Atelectasis, pneumonia, and pulmonary edema are possible; prevention includes incentive spirometry, deep breathing, early ambulation, adequate pain control, coughing technique, hydration.
• D. Pneumonia prevented solely by prophylactic antibiotics; no ambulation.

Answer: (C)

Postoperative lung problems come from multiple sources, and prevention works best with a combination approach that supports lung expansion, airway clearance, and pain control. After surgery, shallow breaths and mucus buildup can cause alveolar collapse (atelectasis) and set the stage for pneumonia. Pulmonary edema can also occur in some patients, especially with fluid shifts or cardiac strain, so it’s realistic to consider more than one pulmonary issue.

The strongest answer recognizes that several complications are possible and that prevention includes a bundle of strategies: incentive spirometry and deep breathing to re-expand and keep the airways open; early ambulation to promote ventilation and mucus clearance; adequate pain control so patients can take deep breaths and cough effectively; coughing technique to mobilize secretions; and hydration to keep mucus thin and easier to clear. Together, these measures address the root causes of atelectasis and help prevent pneumonia, while also acknowledging that edema is a potential concern in the postoperative period.

Options that focus on only one issue or rely on a single measure miss the breadth of prevention needed. For example, suggesting only deep breathing or assuming pneumonia is prevented by antibiotics alone ignores the multifactorial nature of these complications and the importance of mobilization and airway clearance strategies.
