ATI Comprehensive Exit Exam

Correct Answer: C

Rationale: The correct action for the nurse to take when caring for a client with a chest tube connected to a water-seal drainage system is to add sterile water to the water-seal chamber. This is necessary to maintain the correct water level for proper chest tube function. Clamping the chest tube during ambulation (Choice A) is incorrect as it can lead to complications by obstructing drainage. Keeping the collection chamber below the level of the chest (Choice B) is incorrect because it should be kept below the chest to facilitate drainage. Emptying the collection chamber every 12 hours (Choice D) is incorrect as it should be emptied whenever it reaches the fill line or as per facility policy, not on a fixed time schedule.

Correct Answer: A

Rationale: The correct answer is A: INR. The INR (International Normalized Ratio) is the laboratory test used to monitor the therapeutic response of warfarin. It helps ensure that the client's clotting time is within the desired range to prevent complications such as excessive bleeding or clotting. Choice B, aPTT (Activated Partial Thromboplastin Time), is not typically used to monitor warfarin therapy but rather for assessing heparin therapy. Choice C, Platelet count, assesses the number of platelets in the blood and is not specifically used to monitor warfarin therapy. Choice D, Hemoglobin A1C, is a test used to monitor long-term blood sugar control in diabetic patients and is not relevant to monitoring warfarin therapy.

Correct Answer: A

Rationale: The correct answer is A because clients taking warfarin should have their INR (International Normalized Ratio) checked regularly to monitor the medication's effectiveness and adjust the dose if needed. This monitoring helps to ensure the medication is working correctly and the client is within the therapeutic range. Choice B is incorrect because clients on warfarin should not avoid leafy green vegetables but should maintain a consistent intake. Leafy green vegetables contain vitamin K, which can affect warfarin, so it's important to maintain a consistent intake to keep INR stable. Choice C is incorrect as clients should not stop taking warfarin abruptly without consulting their healthcare provider as it can lead to serious health risks like blood clots. Choice D is incorrect because while taking warfarin, it is important to avoid unnecessary aspirin use due to an increased risk of bleeding. However, this statement does not indicate an understanding of the teaching about the need for regular INR monitoring.

Correct Answer: C

Rationale: The correct answer is C. Trimming toenails straight across is essential for clients with diabetes to prevent the risk of ingrown toenails and injury. Using lotion on feet can be beneficial but should not be applied between the toes to avoid moisture buildup, which can lead to infections. Soaking feet in warm water can lead to dry skin, increasing the risk of cracks and other complications. Applying a heating pad to feet when they feel cold is not recommended for clients with diabetes due to impaired sensation, which can result in burns and other injuries.

Correct Answer: C

Rationale: The correct answer is C: 'Use a Z-track technique to administer the injection.' When administering IM injections, using a Z-track technique helps prevent medication from leaking into subcutaneous tissues. This technique involves pulling the skin laterally, injecting the medication deeply into the muscle, and then releasing the skin. Choice A is incorrect because massaging the injection site after administering the medication can lead to increased blood flow and potential leakage of the medication. Choice B is incorrect as the needle should typically be inserted at a 90� angle for IM injections to ensure proper delivery into the muscle. Choice D is incorrect as aspirating for blood before injecting the medication is not routinely recommended for IM injections.
