Correct Answer: D

Rationale: The correct answer is D, Madeleine Leininger's nursing theory. Leininger's Cultural Care Theory emphasizes the importance of providing culturally congruent care to individuals, taking into account their cultural beliefs, values, and practices. This theory is particularly relevant when caring for immigrants as it helps nurses understand and address their unique cultural needs. A: Martha Rogers' nursing theory focuses on the science of unitary human beings and energy fields, not specifically on cultural care. B: Dorothea Orem's nursing theory, the Self-Care Deficit Theory, emphasizes the individual's ability to perform self-care activities, not specifically cultural care. C: Hildegard Peplau's nursing theory, the Theory of Interpersonal Relations, focuses on the nurse-patient relationship and therapeutic communication, not specifically on cultural care for immigrants.

Correct Answer: C

Rationale: The correct answer is C because lacking consistent providers is a common issue among the poor utilizing Medicaid. This impacts continuity of care, leading to fragmented health services and poor health outcomes. Choice A is incorrect as Medicaid does provide some level of access to healthcare. Choice B is incorrect as unnecessary treatments are not a common issue among the poor on Medicaid. Choice D is incorrect as preventive services are underutilized rather than abused by the poor on Medicaid.

Correct Answer: C

Rationale: The correct answer is C: Rauwolfia serpentina. Reserpine is derived from the Rauwolfia serpentina plant. This plant contains alkaloids that act as a central nervous system depressant, reducing anxiety and lowering blood pressure. Atropa belladonna (A) contains toxic alkaloids, Digitalis purpurea (B) contains cardiac glycosides used for heart conditions, and Cephaelis ipecacuanha (D) contains emetine used for inducing vomiting, none of which are related to reserpine's effects.

Correct Answer: B

Rationale: The correct answer is B because it accurately reflects the shift in focus from tuberculosis in the 1980s to the emergence of the AIDS epidemic in the 1990s in the field of nursing. Tuberculosis was a major concern in the 1980s, and the AIDS epidemic became a primary focus in the 1990s. Choice A is incorrect because it discusses preventable diseases caused by unsafe lifestyles, which is not directly related to the comparison of nursing between the two decades. Choice C is incorrect because it mentions a decrease in ambulatory services in the 1980s leading to an increase in public health nurses in the 1990s, which is not supported by the historical context of nursing during those decades. Choice D is incorrect because it suggests that the demand for advanced practice nurses increased in both the 1980s and the 1990s due to economic reasons and national health concerns, which is not specifically relevant to the comparison between nursing in the two decades.

Correct Answer: B

Rationale: The correct answer is B: letters of commendation. Nursing professionals typically include letters of commendation in their portfolios to showcase their achievements, skills, and positive feedback from colleagues or supervisors. This demonstrates their competence and professionalism. Family pictures (A) and high school achievements (D) are not relevant to a nursing portfolio. Articles describing lack of quality in healthcare (C) could reflect negatively on the professional and are not typically included in a portfolio meant to highlight accomplishments.
