Correct Answer: B

Rationale: The correct answer is to ensure that the client wears an identification bracelet at all times. This intervention helps staff recognize clients who wander and ensures their safety. Placing the client in a well-lit area (Choice A) may be helpful in some cases but does not directly address the issue of wandering. Keeping the client's bed in the lowest position (Choice C) is important for fall prevention but is not directly related to wandering behavior. Using physical restraints (Choice D) is not recommended as the first-line intervention for wandering and should be avoided due to ethical concerns and potential risks.

Correct Answer: A

Rationale: The correct answer is to monitor daily weight. Daily weight monitoring is crucial in assessing fluid balance in patients with heart failure because sudden weight gain can indicate fluid retention. Monitoring input and output (choice B) is important but may not provide a complete picture of fluid balance. Checking for edema (choice C) is a sign of fluid accumulation but may not be as accurate as daily weight monitoring. Monitoring blood pressure (choice D) is important in heart failure management but does not directly assess fluid balance.

Correct Answer: C

Rationale: Checking the client's blood glucose level every 4 hours is essential when managing a client on TPN to monitor for hyperglycemia, a common complication. Monitoring urine output (Choice A) is important but not a priority in this scenario. Administering a bolus of 0.9% sodium chloride (Choice B) is not indicated as it is unrelated to managing TPN. Flushing the TPN line with sterile water (Choice D) is necessary, but it should be done with 0.9% sodium chloride, not water.

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: B

Rationale: Digoxin is commonly prescribed to manage atrial fibrillation by controlling heart rate. While Warfarin is used to prevent blood clots, it is not primarily used for controlling heart rate in atrial fibrillation. Aspirin is not the first-line treatment for atrial fibrillation and is generally not recommended for rhythm control. Lisinopril is an ACE inhibitor used to treat high blood pressure and heart failure, but it is not typically prescribed as the primary medication for managing atrial fibrillation.
