Correct Answer: D

Rationale: The correct answer is D: Homeless individuals. Homeless individuals are the most at risk due to the severe impact of poverty and the downward economic spiral on mental health. Homelessness is often directly linked to poverty and lack of resources, leading to increased stress, trauma, and mental health issues. Homeless individuals face constant instability, lack of access to basic necessities, and higher rates of trauma and violence, all of which significantly contribute to mental health problems. Other choices are less directly associated with the severe impact of poverty and homelessness on mental health. Older adults, individuals with physical disabilities, and single-parent families can also be at risk, but homeless individuals are the most vulnerable due to the extreme conditions they face on a daily basis.

Correct Answer: B

Rationale: The correct answer is B: Nursing process. The nursing process is the systematic framework that guides nurses in providing individualized, holistic care. It involves assessment, diagnosis, planning, implementation, and evaluation. By integrating the nursing process into clinical decision-making, psychiatric-mental health nurses ensure comprehensive and effective care for their patients. Developmental issues (A) are important considerations in mental health nursing but do not serve as the foundation for clinical decision-making. Commitment (C) and accountability (D) are essential traits for nurses but do not directly influence the clinical decision-making process. The nursing process, with its structured approach, serves as the cornerstone for organizing and prioritizing care interventions.

Correct Answer: A

Rationale: Step-by-step rationale: 1. Madeleine Leininger is known for developing the theory of cultural care diversity and universality. 2. Leininger emphasized the importance of understanding and integrating cultural beliefs and practices into nursing care. 3. This theory is particularly relevant in psychiatric-mental health nursing to provide culturally sensitive care. 4. Sister Calista Roy developed the Adaptation Model, Hildegard Peplau the Interpersonal Relations Model, and Dorothea Orem the Self-Care Deficit Theory, which are not directly related to cultural care diversity and universality. Summary: Choice A is correct as Madeleine Leininger is the nursing theorist responsible for the theory of cultural care diversity and universality. Choices B, C, and D are incorrect as they are associated with different nursing theories not focused on cultural care diversity and universality.

Correct Answer: B

Rationale: The correct answer is B (48 to 92 hours) because emergency short-term hospitalization without a court order typically ranges from 48 to 92 hours. This time frame allows for evaluation and stabilization of the patient's condition. Choice A (A maximum of 24 hours) is incorrect as it may not provide sufficient time for proper assessment and treatment. Choice C (3 to 5 days) and Choice D (One week) are also incorrect as they exceed the usual duration of emergency short-term hospitalization without a court order. Therefore, Choice B is the most appropriate option based on the typical time frame for such emergency commitments.

Correct Answer: B

Rationale: The correct answer is B: Public stigma. This is because the nurse is addressing the negative stereotype and discrimination associated with mental health conditions by engaging in a conversation with the receptionist about the derogatory term "psycho." This action aims to challenge and educate the receptionist about the harmful impact of stigmatizing language on individuals with mental health issues. Incorrect choices: A: Lack of knowledge - This choice does not align with the scenario as the nurse is not addressing a lack of knowledge but rather addressing a stigma-related issue. C: Label avoidance - This choice is not relevant to the scenario as the nurse is directly confronting the stigmatizing language used by the receptionist. D: Self-stigma - This choice is not applicable as the scenario involves the nurse addressing the stigma perpetuated by the receptionist, not self-stigma.
