Rationale: The Professional Regulation Commission (PRC) in the Philippines requires nurses like Nurse Merle to comply with 45 units of Continuing Professional Development (CPD) in order to renew their license and continually practice nursing. This is a mandatory requirement to ensure that nurses stay updated with the latest advancements, skills, and knowledge in the field of nursing. By completing the required CPD units, Nurse Merle can enhance her competency, maintain her license, and provide quality care to her patients.

Correct Answer: B

Rationale: Dental caries, commonly known as tooth decay, is characterized by the irreversible demineralization of the enamel and dentin due to acids produced by bacterial activity. This process leads to cavitation and destruction of the tooth structure, ultimately resulting in the formation of a cavity. Gingivitis is inflammation of the gums, periodontitis is inflammation and infection of the supporting structures of the teeth (gums, bone, and ligaments), and a dental abscess is a collection of pus in the tissues surrounding the tooth, none of which are specifically related to the irreversible demineralization of enamel and dentin seen in dental caries.

Correct Answer: C

Rationale: The public health nurse's participation in the essential services that are relevant and accessible to the family and the community includes informing, educating, and empowering the people about health. This is a critical aspect of the role of a public health nurse as it involves engaging with individuals and communities to provide them with accurate information about health promotion, disease prevention, and access to healthcare services. By informing, educating, and empowering the people about health, public health nurses can help individuals and communities make informed decisions about their health and well-being, leading to improved health outcomes and overall community health.

Correct Answer: A

Rationale: Prolonged rupture of membranes (>24 hours) increases the risk of intrauterine infection for both the mother and the fetus. When the amniotic sac has been ruptured for an extended period, there is a higher likelihood of bacteria entering the uterus, leading to chorioamnionitis (inflammation of the fetal membranes due to infection). Intrauterine infection can be dangerous for both the mother and fetus, potentially causing sepsis, preterm labor, and other complications. Therefore, it is crucial for the nurse to assess for signs and symptoms of infection in both the mother and fetus when managing a woman in active labor with prolonged rupture of membranes.
