The World Health Organization defines health as:

Correct Answer: B

Rationale: Step 1: The definition of health according to the World Health Organization (WHO) includes physical, mental, and social well-being. Step 2: It emphasizes that health is not just the absence of disease but a holistic state of well-being. Step 3: This definition aligns with the modern understanding of health as a multi-dimensional concept. Step 4: Option B directly mirrors the WHO definition, making it the correct answer. Summary: Option A is too vague and lacks the specific components mentioned by WHO. Option C focuses on the ecosystem, not the individual's well-being. Option D describes public health efforts, not the definition of health itself.

Correct Answer: C

Rationale: The correct answer is C: Dr. C. E. Winslow. Dr. Winslow is known for defining public health as "the science and art of preventing disease, prolonging life, and promoting health through organized efforts of society." He published this definition in his book in 1920, which became a cornerstone in defining public health. Ruth B. Freeman and Lilian Wald were notable figures in public health, but they did not originate the classic definition. The World Health Organization Expert Committee on Nursing is not directly associated with the classic definition of public health.

Correct Answer: B

Rationale: The correct answer is B: Public health nurse. Public health nurse specifically refers to nurses working in local/national health departments or public schools, focusing on promoting and protecting the health of communities. Choice A, public health nursing, is a broader term encompassing various nursing roles in public health settings. Choices C and D, registered midwives and registered nurses, do not specifically indicate nurses working in public health departments or schools.

Correct Answer: A

Rationale: The correct answer is A: Public health nursing. Community health nursing practiced in the public sector focuses on promoting health and preventing diseases within communities. Public health nursing specifically addresses the health needs of the population at large, aiming to improve overall health outcomes. Registered nurse (C) and registered midwives (D) are specific roles within the healthcare system, but they do not encompass the broader scope of community health nursing in the public sector. Public health nurse (B) is a close choice, but it specifically refers to the individual healthcare professional rather than the practice itself.

Correct Answer: B

Rationale: The correct answer is B: Statistics. Statistics is the systematic approach of obtaining, organizing, and analyzing numerical facts to draw conclusions. Vital statistics (A) refer to data related to births, deaths, marriages, and divorces. Morbidity (C) refers to the incidence of illness in a population. Mortality (D) refers to the incidence of death in a population. Therefore, the other choices are incorrect as they do not specifically pertain to the systematic approach of analyzing numerical facts.
