Correct Answer: C

Rationale: Corrected Rationale: An increased respiratory rate is a common finding in clients with ARDS as the body attempts to compensate for impaired gas exchange. Barrel-shaped chest (Choice A) is associated with conditions like COPD, not ARDS. Bradycardia (Choice B) is unlikely in ARDS due to the body's compensatory mechanisms to improve oxygenation. Tracheal deviation (Choice D) is not typically seen in ARDS and is more suggestive of other respiratory conditions.

Correct Answer: C

Rationale: The correct answer is C. Clients on warfarin therapy need to have their International Normalized Ratio (INR) checked regularly to monitor the medication's effectiveness and prevent complications like clotting or bleeding. Option A is incorrect because increasing leafy green vegetables can affect INR levels due to their vitamin K content. Option B is incorrect as grapefruit juice is not a significant concern with warfarin. Option D is important for medication adherence but does not specifically address the monitoring aspect required for warfarin therapy.

Correct Answer: C

Rationale: The correct intervention for a client with DVT is to apply cold packs to the affected extremity. Cold packs can help reduce swelling and pain by constricting blood vessels. Massaging the affected extremity can dislodge a clot and worsen the condition. Elevating the affected extremity helps with blood flow but is not the priority intervention for DVT. Performing range-of-motion exercises on the affected extremity can also dislodge a clot and is contraindicated.

Correct Answer: C

Rationale: To prevent aspiration in clients receiving continuous enteral feedings, the nurse should elevate the head of the bed to 45 degrees. This position helps reduce the risk of regurgitation and aspiration. Flushing the tube with water every 4 hours (Choice A) is important for maintaining tube patency but does not directly prevent aspiration. Positioning the client on the left side during feedings (Choice B) is not specifically related to preventing aspiration in this context. Checking gastric residual every 2 hours (Choice D) is important to assess feeding tolerance but does not directly prevent aspiration.

Correct Answer: D

Rationale: The correct answer is D. Warfarin's effectiveness is reduced by high intake of vitamin K-rich foods, so increasing their intake would contradict the treatment plan. Choices A, B, and C are all appropriate statements for a client on warfarin therapy. Avoiding vitamin K-rich foods helps maintain the medication's effectiveness, avoiding aspirin reduces the risk of bleeding, and monitoring blood pressure is essential for overall health monitoring.
