A nurse is teaching a patient with hypertension about the DASH diet. What is the most important instruction to include?

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: 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.

Correct Answer: B

Rationale: The most effective intervention in preventing deep vein thrombosis (DVT) in a postoperative patient is to encourage early ambulation and leg exercises. Early ambulation helps promote circulation, preventing stasis and reducing the risk of blood clot formation. Encouraging the patient to drink plenty of fluids (choice A) is important for overall health but is not the most effective intervention for preventing DVT. Administering anticoagulants (choice C) is a valuable intervention in some cases, but it may not be suitable for all postoperative patients. Applying compression stockings (choice D) can help prevent DVT but is generally not as effective as early ambulation and leg exercises in postoperative patients.

Correct Answer: B

Rationale: The correct answer is to discontinue the medication and notify the healthcare provider when a patient is experiencing an allergic reaction to a medication. This action is crucial to prevent further harm to the patient. Monitoring blood pressure (choice A) or urine output (choice D) may be important but is not the priority when managing an allergic reaction. Administering an antihistamine (choice C) should only be done after discontinuing the medication and consulting with the healthcare provider.

Correct Answer: C

Rationale: Elevating the head of the bed to 30-45 degrees is the most appropriate intervention to prevent aspiration in a patient with an NG tube. This position helps reduce the risk of regurgitation and aspiration by promoting the proper flow of contents through the gastrointestinal tract and minimizing the chances of stomach contents entering the airway. Flushing the NG tube with water before each feeding may not directly prevent aspiration. Checking the placement of the NG tube is important but does not specifically address the prevention of aspiration. Providing oral care every 4 hours is essential for maintaining oral hygiene but is not directly related to preventing aspiration in a patient with an NG tube.
