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: B

Rationale: A fracture near the epiphysis can result in retarded bone growth, so this should be communicated to the parents.

Correct Answer: D

Rationale: The most critical action for the LPN/LVN to take in this situation is to ask security to ensure the room is safe. This step is crucial to prevent any further harm to the unconscious client or others. While it is important to assess the client's condition, ensuring safety takes precedence. Calling security from the room may expose the LPN/LVN to potential danger without confirming the safety of the environment first. Finding out if anyone else is in the room can wait until safety is established to avoid unnecessary risks.

Correct Answer: A

Rationale: The correct approach when measuring a client's blood pressure, especially for a client with hypertension, is to obtain the blood pressure under the same conditions each time. Consistency in measurement conditions helps ensure accurate and comparable blood pressure readings. Using a different arm for each measurement (Choice B) is not ideal as it can lead to variations in readings. Measuring the blood pressure while the client is standing (Choice C) is not the standard practice and may not provide accurate results. Taking multiple readings at different times of the day (Choice D) may be useful for monitoring blood pressure trends but is not the priority when ensuring accurate individual readings.

Correct Answer: A

Rationale: The correct instruction to prevent back injuries while lifting is to spread your feet apart to provide a wide base of support. This helps in maintaining stability and reduces the risk of back injury. Choice B is incorrect as lifting objects with your back straight and using your legs is the recommended technique. Choice C is incorrect because assistive devices can actually help prevent back injuries by providing support. Choice D is incorrect as bending at the waist to reach objects can strain the back muscles and increase the risk of injury.
