Correct Answer: B

Rationale: A nurse navigator's primary role is to coordinate complex care for patients, guiding them through the healthcare system. Choice A is incorrect because nurse navigators do not provide direct patient care like nurses in clinical settings. Choice C is incorrect as nurse navigators focus on patient care coordination rather than administrative tasks. Choice D is incorrect as managing clinical trials is typically not within the scope of a nurse navigator's responsibilities.

Correct Answer: A

Rationale: Satisficing is the correct decision-making strategy in this scenario. The nurse manager is not aiming for the best solution but rather choosing an alternative that is good enough given the circumstances of staff shortage. Choice B, Routine, does not apply here as the situation is not part of the manager's regular tasks. Choice C, Adaptive, involves adjusting to new conditions, which is not the primary focus in this scenario. Choice D, Rationalizing, does not fit as the decision made is more about finding an acceptable solution rather than justifying it.

Correct Answer: A

Rationale: This is an example of the ethical principle of autonomy.

Correct Answer: D

Rationale: The correct answer is D: 'Approving healthcare facilities.' The Joint Commission's primary role is to accredit and certify healthcare organizations and programs in the United States. This accreditation ensures that healthcare facilities meet specific quality and safety standards. Choices A, B, and C are incorrect because the Joint Commission focuses on evaluating and accrediting healthcare facilities rather than advocating for patients, providing direct care, or setting standards for patient care.

Correct Answer: A

Rationale: In a protective environment for a client with an allogeneic stem cell transplant, the nurse needs to wear an N95 respirator when providing direct care to the client. This precaution is essential to protect the client, whose immune system is compromised after the transplant, from exposure to potential pathogens. Placing the client in a private room with negative-pressure airflow (choice B) is more appropriate for clients with airborne infections. Ensuring the client's room has sufficient air exchanges (choice C) is important for maintaining air quality but is not the primary precaution for protecting an immunocompromised client. Making the client wear a mask when outside the room due to construction (choice D) focuses on external factors and does not directly address the risk of infection during direct care.
