A nurse performs a variety of tasks as part of the nurse's position at a hospital. Whichtask best exemplifies public health?

Correct Answer: D

Rationale: The correct answer is D because facilitating a community-wide smoking cessation program directly impacts public health on a larger scale by addressing a common health issue at a community level. This task focuses on preventive measures and health promotion, which are key aspects of public health initiatives. In contrast, choices A, B, and C primarily involve individual patient care and education, which do not have the same broad impact on public health. Reading nursing journals and instructing a client on wound care are important for individual patient outcomes, while participating in a videoconference call with a remote client focuses on improving access to care but does not necessarily address broader public health concerns.

Correct Answer: B

Rationale: The correct answer is B because reducing health inequity, decreasing disparities, and improving the health of certain groups align with the Healthy People 2020 goal of achieving health equity. This goal focuses on addressing social determinants of health to ensure everyone has the opportunity to achieve their full health potential. Choices A, C, and D do not specifically address health equity or disparities, making them incorrect for this question. A focuses on preventable diseases, C on creating healthy environments, and D on promoting healthy behaviors for the elderly, which are important but not the primary focus of the Healthy People 2020 initiative.

Correct Answer: A

Rationale: The correct answer is A: Elimination of common infectious diseases. This is a significant public health achievement in the 20th century due to the development of vaccines and antibiotics, leading to the eradication or control of diseases like smallpox and polio. This achievement has had a substantial impact on improving population health. Summary: - Choice A is correct as it directly addresses a major public health milestone. - Choice B is incorrect as recognizing tobacco as a health hazard, while important, is not a specific public health achievement in the 20th century. - Choice C is incorrect as fluoridation of drinking water is a notable public health intervention but not one of the great achievements in the 20th century. - Choice D is incorrect as healthier mothers and babies is an important public health goal but does not represent a specific achievement in the 20th century.

Correct Answer: A

Rationale: Step 1: Increasing number of people with acute conditions implies a greater demand for continuous monitoring. Step 2: Home monitoring devices allow for convenient and cost-effective monitoring of individuals with acute conditions. Step 3: This trend is supported by the rising prevalence of chronic diseases. Step 4: Other choices are incorrect as they don't directly address the primary reason for the increasing use of home monitoring devices, which is the rising number of people with acute conditions.

Correct Answer: A

Rationale: The correct answer is A, the shorter length of stay in long-term care facilities. This has led to an increase in the number of acute and chronically ill people in the community needing professional nursing care because individuals are being discharged from long-term care facilities sooner than before. Consequently, these individuals require ongoing nursing care and support once they return to the community. This change in healthcare practices has resulted in a higher demand for professional nursing care services outside of institutional settings. Summary: - Choice B (Increase in ambulatory surgery) is incorrect as it does not directly lead to an increase in the number of individuals needing professional nursing care in the community. - Choice C (Decrease in the use of outpatient clinics) is incorrect as a decrease in outpatient clinic use does not necessarily result in more individuals needing professional nursing care in the community. - Choice D (Increase in length of stay in emergency departments) is incorrect as it focuses on emergency care rather than the transition of individuals from long-term care facilities to the
