ATI RN Exit Exam Test Bank

Correct Answer: B

Rationale: The correct answer is B: PT/INR. When a patient is on warfarin therapy, healthcare providers monitor the PT/INR levels to evaluate the effectiveness of the treatment and assess the risk of bleeding. Monitoring potassium, sodium, or calcium levels is not directly related to warfarin therapy and would not provide the necessary information needed to manage the medication effectively.

Correct Answer: B

Rationale: The correct answer is Hypokalemia. Furosemide is a loop diuretic that can lead to potassium depletion by increasing its excretion in the urine. Hypokalemia is a common and concerning side effect of furosemide therapy. Hyperkalemia (Choice A) is less likely as furosemide tends to lower potassium levels. Hyponatremia (Choice C) is more commonly seen with thiazide diuretics. Hypercalcemia (Choice D) is not directly associated with furosemide use.

Correct Answer: C

Rationale: The correct answer is C because clients taking metformin should avoid alcohol as it increases the risk of lactic acidosis. Choices A, B, and D are incorrect. Choice A is not specific to metformin but rather a general recommendation for some medications. Choice B is a good practice for medication adherence but does not relate specifically to metformin. Choice D is inaccurate as weight gain is not an expected side effect of metformin.

Correct Answer: A

Rationale: The correct action to prevent aspiration in a client with a nasogastric tube is to elevate the head of the bed to 45 degrees during feedings. This positioning helps reduce the risk of regurgitation and aspiration of gastric contents. Placing the client in the left lateral position after feedings does not directly prevent aspiration. Flushing the tube with sterile water before each feeding is important for tube patency but does not specifically prevent aspiration. Checking gastric residuals every 8 hours is necessary to monitor the client's tolerance to feedings but is not a direct preventive measure against aspiration.

Correct Answer: A

Rationale: Naloxone is the correct answer. Naloxone is specifically used to reverse the effects of opioid overdose by binding to opioid receptors and blocking the effects of opioids. Epinephrine is mainly used to treat severe allergic reactions, Atropine is used for certain types of heart conditions and to reduce salivation or respiratory secretions, and Lidocaine is a local anesthetic used for numbing purposes. Therefore, choices B, C, and D are incorrect in the context of reversing opioid overdose.
