Correct Answer: B

Rationale: To administer 10 mg of metoclopramide, the nurse should administer 2 mL (10 mg / 5 mg per mL). Therefore, the correct answer is 2 mL. Choice A (1 mL) is incorrect because it would only deliver 5 mg of metoclopramide, which is half the required dose. Choice C (3 mL) and D (4 mL) are incorrect as they would provide more than the required dose of 10 mg.

Correct Answer: B

Rationale: The correct teaching point is to maintain two points of support on the ground at all times when using a cane. This ensures stability and helps distribute weight evenly. Choice A is incorrect because the cane should be used on the stronger side of the body to provide support to the weaker leg. Choice C is incorrect as advancing the cane too far with each step can lead to imbalance. Choice D is incorrect as advancing the cane and the strong leg simultaneously may not provide adequate support for the weaker leg.

Correct Answer: C

Rationale: The best intervention for a client with dementia who frequently attempts to get out of bed unsupervised is to use a bed exit alarm system (Choice C). A bed exit alarm can alert staff when the client tries to leave the bed, helping to prevent falls. Using restraints (Choice A) is not recommended as it can lead to physical and psychological harm. While having family members present (Choice B) can be beneficial, it may not be feasible at all times. Keeping the client's room dark and quiet (Choice D) may not address the immediate safety concern of the client attempting to get out of bed.

Correct Answer: B

Rationale: The correct answer is B: 'Avoid drinking grapefruit juice.' Grapefruit juice can increase the risk of toxicity when taken with simvastatin. Instructing the client to avoid grapefruit juice helps prevent this interaction. Choice A is incorrect because the timing of medication administration for simvastatin is usually in the evening. Choice C is unrelated to simvastatin therapy. Choice D is not necessary for monitoring while taking simvastatin.

Correct Answer: C

Rationale: Administering oral acetaminophen is the appropriate intervention for a client with hyperthermia. Acetaminophen helps to reduce fever by lowering the body's temperature. Submerging the client's feet in ice water can lead to shock and is not recommended. Using a thermal blanket may worsen the condition by trapping heat. Initiating seizure precautions is not directly related to managing hyperthermia.
