A nurse is caring for a client diagnosed with adult respiratory distress syndrome (ARDS) and being treated with positive end expiratory pressure (PEEP). How does PEEP benefit the client?

It decreases trapped oxygen in the alveoli.

It promotes independent breathing efforts.

It keeps the airways and small lung spaces open.

It facilitates weaning off the mechanical ventilator.

Answer and Explanation

The Correct Answer is C

Choice A rationale
PEEP does not decrease trapped oxygen in the alveoli. Instead, it helps to increase the volume of gas remaining in the lungs at the end of expiration, which can improve oxygenation.
Choice B rationale
PEEP does not directly promote independent breathing efforts. It is a mode of mechanical ventilation used to support a patient’s breathing.
Choice C rationale
PEEP keeps the airways and small lung spaces open by increasing the pressure in the lungs at the end of expiration. This can prevent alveolar collapse and improve oxygenation in patients with conditions like ARDS23.
Choice D rationale
While PEEP can be used in the process of weaning a patient off mechanical ventilation, its primary benefit is not facilitating weaning. It is used to improve oxygenation and prevent alveolar collapse.

Correct Answer is C

Explanation

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.

A. Medication errors are adverse events. B. Errors of execution are usually intentional and occur because of time or resource constraints. C. As many as 90% of medication errors are preventable. D. Poorly coordinated care and nosocomial infections are examples of errors.

Correct Answer is C

Explanation

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.
