A nurse is caring for a patient at risk for atelectasis.

Which independent nursing measure should the nurse prioritize to prevent the development of atelectasis?

Choice A rationale
While the application of anti-embolism stockings can be beneficial in preventing deep vein thrombosis in postoperative patients, it is not the most prioritized nursing intervention in the immediate postoperative period for a patient who has undergone a left pneumonectomy. The immediate postoperative period after a pneumonectomy is critical for monitoring and managing potential complications such as respiratory distress, hemorrhage, and bronchopleural fistula.
Choice B rationale
The use of the incentive spirometer is an important nursing intervention for postoperative patients to promote lung expansion and prevent atelectasis. However, in the immediate postoperative period following a pneumonectomy, the priority is to monitor for complications and ensure the stability of the patient.
Choice C rationale
Assessment of the chest tube and pleur-evac is the most prioritized nursing intervention in the immediate postoperative period for a patient who has undergone a left pneumonectomy. After a pneumonectomy, a chest tube is placed to drain air, blood, and fluid from the pleural space to allow the remaining lung to re-expand. It is crucial to monitor the chest tube system for proper functioning and to assess for complications such as excessive bleeding, infection, or pneumothorax.
Choice D rationale
Repositioning the patient in bed is a standard nursing intervention in postoperative care to enhance comfort, promote lung expansion, and prevent complications such as pressure ulcers and deep vein thrombosis. However, it is not the most prioritized intervention in the immediate postoperative period following a pneumonectomy, where monitoring for respiratory complications and ensuring the stability of the patient are paramount.

Choice A rationale
While medication errors are indeed considered adverse events, this statement does not fully capture the scope of patient safety and prevention of harm.
Choice B rationale
Errors of execution are usually unintentional, not intentional. They often occur due to system failures rather than time or resource constraints.
Choice C rationale
It is estimated that as many as 90% of medication errors are preventable. This highlights the importance of safety measures and protocols in healthcare settings to prevent harm to patients.
Choice D rationale
Poorly coordinated care and nosocomial infections are examples of errors, but they represent only a fraction of the potential safety issues in healthcare.
