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.

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.

Correct Answer: A

Rationale: The correct answer is A: Vital statistics. Vital statistics refer to the systematic study of vital events such as births, illnesses, marriages, divorce, separation, and deaths. This field focuses on collecting, analyzing, and interpreting data related to these events in a population. Choice B (Statistics) is too broad and does not specifically focus on vital events. Choice C (Morbidity) refers to the incidence of illness in a population, not the study of all vital events. Choice D (Mortality) specifically refers to deaths and does not encompass all vital events studied in vital statistics. Therefore, A is the correct answer as it directly relates to the systematic study of the listed vital events.
