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: C

Rationale: The correct answer is to lock the wheels on the bed and wheelchair. This action helps prevent accidents by stabilizing the equipment during the transfer process. Having the patient use a gait belt for support (choice A) can be helpful but is not directly related to equipment safety. Encouraging the patient to hold onto a walker (choice B) is beneficial for ambulation but does not address the safety of equipment. Asking the patient to transfer independently (choice D) can pose risks, especially for a patient with limited mobility, and may not ensure safety during the transfer.

Correct Answer: D

Rationale: The correct answer is to use a dedicated blood pressure cuff that stays in the room and is used for that patient only. Patients on contact precautions require dedicated equipment to prevent the spread of disease. Using one blood pressure cuff exclusively for the patient on contact precautions helps minimize the risk of transmitting infections to other patients. Choices A, B, and C are incorrect because while wearing protective gear and isolating the patient in a room with negative airflow are important infection control measures, using dedicated equipment for the patient on contact precautions is specifically recommended to prevent the spread of disease in this scenario.

Correct Answer: B

Rationale: The correct answer is B: Nonmaleficence. Nonmaleficence is the ethical principle that emphasizes the obligation to do no harm, making it crucial in medical decision-making. In the context of a bone marrow transplant for a client with leukemia, the primary concern is to minimize harm and avoid causing any unnecessary suffering or adverse effects. Choices A, C, and D are incorrect: Justice relates to fairness in resource allocation and treatment decisions, Autonomy involves respecting the patient's right to make decisions about their own care, and Beneficence refers to the obligation to act in the patient's best interest and promote their well-being, which may involve some level of risk or harm for overall benefit.

Correct Answer: B

Rationale: When a nurse is uncomfortable documenting a verbal prescription, the best course of action is to clarify the prescription with the healthcare provider. This is crucial to ensure that the information is accurate and to provide safe and appropriate care. Option A is incorrect because blindly documenting without seeking clarification can lead to errors. Option C is incorrect as refusing to document the prescription altogether is not in the best interest of the patient. Option D is also incorrect as speaking with the client's family is not the appropriate step to clarify a verbal prescription; the healthcare provider should be the primary source for this clarification.
