Correct Answer: D

Rationale: Dr. Margaret Shetland emphasized that the philosophy of public health nursing is rooted in the belief in the worth and dignity of every individual. This principle underscores the core values of public health nursing, focusing on respect for human life and the promotion of health for all individuals, regardless of their background or circumstances.

Correct Answer: A

Rationale: The primary purpose of conducting an epidemiologic investigation is to delineate the etiology of the epidemic, which involves identifying the cause or origin of the disease outbreak. This process helps in understanding how the disease spreads, its risk factors, and developing strategies for control and prevention.

Correct Answer: A

Rationale: Since each rural health midwife is typically assigned a population of about 5,000, with the municipality's total population being 20,000, the existing 3 midwives can cover the current population adequately. Therefore, the RHU would not need any more midwife positions, making option A, '1', the correct answer.

Correct Answer: D

Rationale: The most prominent feature of public health nursing is its focus on preventive services rather than curative ones. Public health nursing aims to prevent diseases and promote health within the community by implementing interventions that target the population as a whole. This focus distinguishes public health nursing from other types of nursing that primarily provide curative care to individuals. Preventive services play a significant role in improving the overall health outcomes of communities and reducing the burden of disease.

Correct Answer: D

Rationale: When the RHU requires additional midwife items, the request for approval should be submitted to the Municipal Health Board. According to R.A. 7160, basic health services have been decentralized from the national government to local government units, including municipalities. The Municipal Health Board plays a crucial role in overseeing health-related matters at the local level, making it the appropriate authority to seek approval for additional midwife items.
