Correct Answer: C

Rationale: The correct answer is C: Anxiety about unfinished business. The patient's desire to settle issues with their siblings before death indicates a concern about unresolved matters. This response aligns with the concept of psychosocial responses to death, specifically the need for closure and resolution. Restlessness (choice A) may not necessarily indicate a specific focus on unfinished business. Yearning and protest (choice B) typically refer to the initial stages of grief, not specifically related to settling unresolved issues. Fear of the meaninglessness of one's life (choice D) is more existential and philosophical, whereas the patient's focus here is on addressing specific issues with their siblings.

Correct Answer: C

Rationale: The correct answer is C: Primary nursing. Primary nursing is a care delivery model where one nurse is responsible for the total care of a group of clients over a 24-hour period. This promotes continuity of care, individualized attention, and better nurse-client relationships. In primary nursing, the nurse plans and directs care, coordinates with other healthcare team members, and serves as the main point of contact for the clients. A: Case management involves coordinating care across different healthcare providers and services, not necessarily focusing on a specific group of clients over a 24-hour period. B: Team nursing involves a team of healthcare providers working together to deliver care, rather than one nurse being responsible for a specific group of clients over a 24-hour period. D: Functional nursing divides tasks among different healthcare team members based on their specific skills, which may not provide the same level of continuity and individualized care as primary nursing.

Correct Answer: B

Rationale: The correct answer is B: Advocacy and moral agency. In this scenario, the Ethiopian man with AIDS is in a vulnerable position due to lack of health insurance and understanding of Medicaid coverage. Advocacy skills are crucial to help him navigate the complex healthcare system and access the necessary resources. Moral agency involves advocating for the patient's rights and well-being, ensuring that he receives appropriate care despite his socioeconomic status. Clinical judgment, collaboration, and systems thinking are important competencies but not as directly relevant in this specific situation of advocating for the patient's access to Medicaid coverage.

Correct Answer: C

Rationale: Step-by-step rationale for why choice C is correct: 1. Intrapulmonary shunting refers to blood bypassing the normal oxygenation process in the lungs. 2. Choice C describes blood being shunted from the right side of the heart (deoxygenated blood) to the left side without oxygenation, leading to systemic circulation without oxygenation. 3. Choices A, B, and D do not accurately describe intrapulmonary shunting as they focus on other concepts like alveolar perfusion, heart failure, and unilateral lung blood supply, respectively.

Correct Answer: B

Rationale: The correct answer is B because a low Mean Arterial Pressure (MAP) indicates inadequate perfusion, which may require adjusting the norepinephrine infusion rate to increase blood pressure. A: A heart rate of 58 beats/minute is within a normal range and may not necessarily indicate a need for adjustment. C: Elevated Systemic Vascular Resistance (SVR) may be an expected response to norepinephrine and does not necessarily indicate a need for adjustment. D: A low Pulmonary Artery Wedge Pressure (PAWP) may indicate fluid volume deficit but does not directly relate to the need for adjusting norepinephrine infusion rate.
