ATI RN Exit Exam Test Bank

Correct Answer: A

Rationale: The correct answer is to monitor aPTT in patients receiving heparin therapy. Activated Partial Thromboplastin Time (aPTT) is crucial to assess the therapeutic effectiveness of heparin and to prevent bleeding complications. Monitoring INR (Choice B) is more relevant for patients on warfarin therapy, not heparin. Platelet count (Choice C) monitoring is essential for detecting heparin-induced thrombocytopenia rather than assessing heparin therapy itself. Monitoring sodium levels (Choice D) is not directly related to heparin therapy monitoring.

Correct Answer: C

Rationale: The correct intervention for a client with deep vein thrombosis (DVT) is to elevate the affected extremity above the level of the heart. This position promotes venous return, reduces swelling, and helps prevent complications such as pulmonary embolism. Applying cold compresses (choice A) can vasoconstrict blood vessels, potentially worsening the condition. Massaging the affected extremity (choice B) can dislodge the clot and lead to serious complications. Keeping the affected extremity dependent when sitting (choice D) can hinder venous return and exacerbate the DVT.

Correct Answer: C

Rationale: Positioning the client with the head of the bed elevated at 45 degrees is crucial during enteral feedings to prevent aspiration. This position helps reduce the risk of regurgitation and aspiration of feedings into the lungs. Option A is not necessary before feedings. Placing the client in a supine position (Option B) increases the risk of aspiration. Checking gastric residuals every 8 hours (Option D) is important but not directly related to positioning during enteral feedings.

Correct Answer: D

Rationale: The correct answer is to monitor the client's respiratory rate. When a client is receiving opioids, the priority assessment is the respiratory rate since opioids can lead to respiratory depression. Monitoring urinary output, blood pressure, and constipation are also important but not the priority in this scenario.

Correct Answer: B

Rationale: The correct answer is B: 'Avoid consuming alcohol while taking this medication.' Clients taking metformin should avoid alcohol as it increases the risk of lactic acidosis. Choice A is incorrect because metformin is usually taken with meals to reduce gastrointestinal side effects. Choice C is incorrect as metformin is typically taken with meals, not at bedtime. Choice D is incorrect because muscle pain is not a common side effect of metformin.
