Correct Answer: D

Rationale: The correct answer is D: Incidence. Incidence refers to the number of new cases of a specific disease or condition within a defined time period. In this scenario, the nursing student is reviewing the number of persons newly diagnosed with major depression in the past year, which aligns with the concept of incidence. This information helps in understanding the risk of developing major depression in a given population over a specific time frame. Now, let's analyze why the other choices are incorrect: A: Rate - This term is too broad and does not specifically address the number of new cases within a defined period. B: Prevalence - Prevalence refers to the total number of cases (both new and existing) of a disease within a specific population at a given time, not just new cases. C: Point prevalence - This term specifically refers to the proportion of a population that has a particular condition at a specific point in time, not the number of new cases within a specific period.

Correct Answer: C

Rationale: The correct answer is C: Self-care. Peplau's model emphasizes the therapeutic nurse-patient relationship, where the nurse helps the patient develop self-awareness, self-understanding, and self-care skills. By identifying self-care as a key component, the nurse promotes the patient's independence and empowerment in managing their mental illness. Incorrect choices: A: Suffering - While suffering may be a part of the patient's experience, it is not a key component in Peplau's model. B: Anxiety - Although anxiety may be present in a patient with mental illness, it is not a central focus of Peplau's model. D: Nonverbal behaviors - While nonverbal behaviors are important in communication, they are not a key component in Peplau's model, which focuses more on the therapeutic relationship and patient-centered care.

Correct Answer: B

Rationale: The correct answer is B because ethical decision-making requires examining assumptions and seeking more information before making a judgment. By questioning assumptions, the nurse can avoid biases and ensure decisions are based on accurate data. This step is crucial in understanding the full context of the ethical dilemma and considering all perspectives involved. Choices A, C, and D are incorrect because focusing on personal feelings, existing knowledge, or patient values alone may not address the root of the ethical issue or lead to a comprehensive decision-making process.

Correct Answer: B

Rationale: The correct answer is B: Reflection. Self-awareness is the process of introspection and understanding one's own thoughts, feelings, and actions. Reflection is a tool that helps individuals explore their experiences, emotions, and beliefs, leading to increased self-awareness. Interdisciplinary care (A) involves collaboration among different healthcare professionals. Plan of care (C) refers to the specific actions and interventions for a patient's treatment. Clinical reasoning (D) is the process of analyzing patient data to make clinical decisions. Reflection is the most appropriate tool for developing self-awareness among healthcare professionals.

Correct Answer: C

Rationale: Axis III in the DSM-5 refers to any relevant medical conditions or physical disorders that may be impacting the patient's mental health. In this case, Chronic obstructive pulmonary disorder (COPD) would be found on Axis III as it is a physical health condition. Cocaine dependence (A) and Bipolar I disorder (B) would be found on Axis I as they are mental health disorders. Cellulitis (D) is a skin infection and would also not be found on Axis III as it is not a chronic physical health condition.
