Correct Answer: B

Rationale: The correct answer is to brush the dentures with a toothbrush and denture cleaner. This action ensures effective cleaning of the dentures. Dentures should be rinsed with cool or lukewarm water, not hot water, to prevent damage. Placing the dentures in a clean, dry storage container is not the immediate next step after cleaning; they should be kept moist to prevent warping.

Correct Answer: D

Rationale: Choice D is the correct response. The body's receptors adapt to the heat over time, which can explain why the client no longer perceives the warmth from the heating pad. This phenomenon is known as thermal adaptation. Choices A, B, and C are incorrect. Choice A is inaccurate because the client not feeling the warmth does not necessarily mean they have derived the maximum benefit. Choice B incorrectly states that blood vessels dilating remove heat, which is not accurate. Choice C suggests increasing the temperature when the pad no longer feels warm, which could potentially lead to burns or discomfort for the client.

Correct Answer: A

Rationale: The correct answer is to administer insulin as prescribed. When a client with diabetes mellitus presents with a critically high blood glucose level like 600 mg/dL, the priority action is to lower the blood glucose level promptly to prevent complications. Insulin is the appropriate medication to rapidly reduce high blood glucose levels. Administering oral hypoglycemic agents may not act quickly enough in this critical situation. While monitoring blood glucose levels frequently is important, immediate intervention to lower the high blood glucose level takes precedence. Providing a high-calorie diet is contraindicated in this scenario as it would further elevate the blood glucose level.

Correct Answer: A

Rationale: The correct action for the nurse to take is to gently shake the container of liquid medication before administration. Shaking the container ensures proper mixing of the medication, which is important to maintain uniformity of the dose. Transferring the medication to a medicine cup (choice B) may not be necessary for a small volume like 0.5 mL. Placing the client in a semi-Fowler's position (choice C) is not directly related to administering liquid medication orally. Verifying the dosage by measuring the liquid (choice D) is important but does not address the specific action needed to prepare the medication for administration.

Correct Answer: C

Rationale: During a Romberg's test, the nurse assesses the client's balance. Having the client stand with arms at her sides and feet together is the correct technique. This position helps the nurse observe for swaying or loss of balance, indicating alterations in balance. Choices A and B are incorrect as they are not part of Romberg's test and do not assess balance. Choice D is also incorrect as direct percussion over the kidneys is not associated with a Romberg's test.
