Correct Answer: A

Rationale: The correct answer is to turn and reposition the patient every 2 hours. This intervention is crucial in preventing pressure ulcers and maintaining skin integrity by relieving pressure on bony prominences. Applying a moisture barrier (Choice B) is important for moisture-associated skin damage but is not the priority in this case. Massaging the patient's skin (Choice C) can potentially cause friction and shear, increasing the risk of skin breakdown. Applying a heating pad (Choice D) can lead to burns or thermal injuries, exacerbating skin integrity issues.

Correct Answer: C

Rationale: The primary purpose of turning and repositioning an immobile patient every 2 hours is to prevent skin breakdown and pressure ulcers. Prolonged immobility can lead to pressure ulcers, making this a crucial nursing intervention. Choice A is incorrect because while turning can help improve circulation and relieve pressure, the primary purpose is to prevent skin breakdown. Choice B is incorrect as preventing contractures and muscle atrophy is important but not the primary purpose of turning. Choice D is incorrect as improving respiratory function and preventing pneumonia are not directly related to turning and repositioning for skin integrity.

Correct Answer: B

Rationale: The correct intervention for a patient receiving a blood transfusion is to monitor the patient for signs of circulatory overload. This is crucial to prevent fluid overload, which can lead to serious complications. Administering antihistamines is not a routine intervention during blood transfusions unless the patient shows signs of an allergic reaction. Ensuring the completion of the blood transfusion within a specific time frame is not as critical as monitoring for circulatory overload. Checking vital signs every 30 minutes is essential, but the specific focus should be on monitoring for signs of circulatory overload.

Correct Answer: C

Rationale: The appropriate action when a client is wearing a necklace before surgery is to ask the patient for permission to lock it in a safe. This is in line with hospital policy to secure valuables before entering surgery. Choice A is incorrect because simply placing the necklace in a drawer may not be secure. Choice B is incorrect as taping the necklace to the patient's skin can cause skin irritation and is not a standard practice. Choice D is incorrect because the responsibility for securing valuables typically lies with the healthcare team, not the patient's family.

Correct Answer: B

Rationale: The correct answer is B: 'Use bed alarms to monitor the client's movements.' When a client with a history of falls is admitted, the nurse's initial intervention should focus on fall prevention measures. Using bed alarms to monitor the client's movements can help alert the healthcare team if the client attempts to get out of bed and reduce the risk of falls. Choice A is incorrect because increasing medication should not be the first intervention as it may not address the underlying causes of falls and can have adverse effects. Choice C may be appropriate but is not the priority over implementing safety measures like bed alarms. Choice D is incorrect as assigning the client to a nursing assistant for supervision alone may not be as effective as utilizing bed alarms for continuous monitoring.
