Correct Answer: D

Rationale: The correct answer is to eat a light snack before bedtime. Consuming a light snack can help promote sleep by preventing discomfort from hunger. Choice A is incorrect because staying in bed for too long when unable to fall asleep can lead to frustration and worsen insomnia. Choice B is incorrect as taking a nap during the day can interfere with nighttime sleep. Choice C is incorrect as exercising before bed can increase alertness and make falling asleep more difficult.

Correct Answer: C

Rationale: The correct instruction for a client prescribed metformin is to take the medication with meals to improve absorption and reduce gastrointestinal upset. Metformin is typically recommended to be taken with food to minimize side effects. Option A is incorrect as taking metformin on an empty stomach may increase the risk of gastrointestinal side effects. Option B is unrelated as metformin does not interact with potassium-rich foods. Option D is also incorrect as metformin does not cause drowsiness, so there is no need to take it before bed.

Correct Answer: B

Rationale: Administering morphine for pain relief is crucial for postoperative clients following a cholecystectomy to manage pain effectively. Placing the client in a supine position may not be ideal as it can cause discomfort and hinder breathing. Applying a warm compress to the incision site can increase the risk of infection. Placing a pillow under the client's knees is not a priority intervention compared to pain management.

Correct Answer: A

Rationale: The correct recommendation for a client with hypertension is to limit sodium intake to no more than 1,500 mg per day. This helps manage hypertension by reducing fluid retention and lowering blood pressure. Choice B is a good recommendation as well, but the primary focus for hypertension management in this scenario is limiting sodium. Choices C and D are incorrect as dairy products and carbohydrates are not directly linked to hypertension.

Correct Answer: D

Rationale: Administering a local anesthetic at the injection site can help reduce pain during immunizations in infants. Options A, B, and C are incorrect. Administering the immunization in the deltoid muscle may not provide pain relief. Applying a cold compress or pressure to the injection site is not as effective as using a local anesthetic to reduce pain.
