Correct Answer: B

Rationale: The correct answer is 'B: Protective environment.' Rubella requires placing the client in a protective environment due to its airborne precautions. Airborne precautions are typically used for diseases that are spread through tiny droplets that remain in the air for an extended period, like tuberculosis. Contact precautions are used for diseases that are spread by direct or indirect contact, such as MRSA. Droplet precautions are implemented for diseases transmitted through respiratory droplets, like influenza. Therefore, in the case of rubella, airborne precautions in a protective environment are necessary.

Correct Answer: A

Rationale: The correct answer is A: Patient outcomes. In a performance model, one of the key indicators that a nurse manager would focus on is patient outcomes. Patient outcomes are a direct reflection of the quality of care provided by the staff, making it a crucial aspect of evaluating performance. Choice B, rapport with staff, though important for team dynamics, is not directly related to a performance model that primarily assesses job performance. Choice C, daily job performance, is relevant but more of an outcome rather than an indicator itself. Choice D, flexibility, is a valuable trait but not specifically highlighted in the context of a performance model.

Correct Answer: B

Rationale: The correct answer is 'Unfreezing the system.' In Lewin's Force-Field Model, unfreezing is the stage where the existing equilibrium is disrupted to motivate participants and prepare them for change. Building trust and recognizing the need for change are essential components of this stage. Choice A, 'Moving the system to a new level,' does not specifically address the initial stage of disruption. Choice C, 'Refreezing the system,' comes after change has been implemented, not before. Choice D, 'Institutionalization,' refers to the stage where the change becomes the new norm, which is different from unfreezing.

Correct Answer: A

Rationale: Commitment to others involves accountability for one’s actions, lifelong learning, and commitment to colleagues.

Correct Answer: B

Rationale: The concept of evidence-based management involves combining managerial expertise with the latest research evidence to make informed decisions. Choice A is incorrect because relying solely on personal experience may not align with the best available evidence. Choice C is incorrect as it emphasizes intuition over research evidence. Choice D is incorrect because evidence-based management involves not only peer-reviewed literature but also incorporating managerial expertise.
