Correct Answer: B

Rationale: The correct answer is B. Placing a gait belt around the patient for support is the safest option when assisting a patient to stand from a sitting position. This belt provides stability and support, reducing the risk of falls or injuries during the transfer. Choices A, C, and D are incorrect. Allowing the patient to pull up on the nurse's arm (Choice A) may lead to instability and compromise safety. Having the patient push off the chair with their hands (Choice C) might not provide sufficient support, especially for patients who require assistance. Asking the patient to lift themselves up without support (Choice D) can be dangerous and increase the risk of falls.

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: D

Rationale: The correct answer is D because touching a patient's skin with sterile gloves compromises the sterility of the gloves, increasing the risk of contamination. Choices A, B, and C demonstrate correct practices in standard precautions. Wearing gloves when changing bed linens and to remove a wound dressing, as well as washing hands after removing gloves, are all appropriate and necessary steps to prevent the spread of infection.

Correct Answer: B

Rationale: When a nurse discovers a discrepancy in the narcotics log, the appropriate next step is to report the discrepancy to the nurse manager. This is important to ensure that the issue is properly investigated and addressed. Choice A is incorrect because simply correcting the log and notifying the pharmacy may not address the root cause of the discrepancy. Choice C is incorrect as re-administering the narcotic without clarification could lead to potential harm or legal issues. Choice D is incorrect as disposing of the narcotic without following proper protocols and documentation could result in further complications.

Correct Answer: B

Rationale: Using bed alarms to prevent falls is the most important intervention to implement for a client with a history of falls. Bed alarms can provide timely alerts to the healthcare team, allowing for quick assistance to prevent falls. Increasing the frequency of bed checks may not necessarily prevent falls as effectively as direct intervention with bed alarms. Keeping the room well lit is important for general safety but may not address the immediate risk of falls. Encouraging the client to use a walker for mobility is beneficial but may not be as crucial as implementing bed alarms to prevent falls in this scenario.
