Which action by the nurse will help prevent ventilator-associated pneumonia (VAP) in a patient on mechanical ventilation?

Correct Answer: A

Rationale: The correct answer is A. Providing oral care every 4 hours helps prevent ventilator-associated pneumonia by reducing the buildup of bacteria in the mouth that can be aspirated into the lungs. Repositioning the patient every 2 hours is important for preventing pressure ulcers but is not directly related to preventing VAP. Suctioning the patient as needed is essential for maintaining airway patency but does not specifically prevent VAP. Administering antibiotics as prescribed is a treatment for infections but does not prevent VAP.

Correct Answer: A

Rationale: The correct answer is to suction the tracheostomy as needed to maintain a patent airway. After a tracheostomy procedure, the immediate concern is airway patency to prevent respiratory compromise. Suctioning helps clear secretions and maintains a clear airway, reducing the risk of respiratory distress. Monitoring the patient's oxygen saturation (choice B) is important but not the priority compared to ensuring a clear airway. Providing humidified air (choice C) and administering pain medication (choice D) are also essential aspects of care for a patient with a tracheostomy, but they are not the priority when immediate airway management is required.

Correct Answer: C

Rationale: The correct answer is to encourage the patient to reduce sodium intake. The Dietary Approaches to Stop Hypertension (DASH) diet emphasizes reducing sodium intake to help manage hypertension. While increasing fruits and vegetables (Choice A) is important in the DASH diet, reducing sodium intake is considered more crucial. Limiting saturated fats (Choice B) is beneficial but not as critical as reducing sodium. Avoiding caffeine (Choice D) is not a specific recommendation of the DASH diet for managing hypertension.

Correct Answer: B

Rationale: The correct answer is to place the patient in a high Fowler's position. This position helps improve lung expansion and oxygenation in cases of pulmonary edema by reducing venous return to the heart and enhancing respiratory mechanics. Administering a diuretic (Choice A) can be important but is not the priority over positioning in this situation. Administering oxygen (Choice C) is essential, but the priority action for improving oxygenation is the positioning of the patient. Monitoring lung sounds (Choice D) is crucial for ongoing assessment but is not the priority action when the patient is in distress with pulmonary edema.

Correct Answer: D

Rationale: The correct answer is to respect the patient's right to refuse the medication. It is crucial to uphold the patient's autonomy and decision-making capacity when it comes to their treatment. Administering the medication later without the patient's consent (Choice B) disregards their autonomy and can lead to ethical issues. Documenting the refusal and notifying the healthcare provider (Choice A) is important for legal and continuity of care purposes but should come after respecting the patient's decision. While explaining the importance of the medication (Choice C) is valuable for promoting understanding and compliance, the immediate concern should be respecting the patient's refusal.
