During which phase would the community health nurse (CHN) determine the ability of specific interventions to achieve an increase to at least 90% in the proportion of all pregnant women who receive first-trimester prenatal care?

Correct Answer: D

Rationale: The correct answer is D: Evaluation phase. During the evaluation phase, the CHN assesses the effectiveness of interventions in achieving the desired outcome of increasing the proportion of pregnant women receiving first-trimester prenatal care to at least 90%. This phase involves systematically collecting and analyzing data to determine if the interventions are successful. In contrast, the assessment phase (choice A) focuses on gathering information about the community's health needs, planning phase (choice B) involves developing strategies to address those needs, and implementation phase (choice C) is about putting the planned interventions into action. Therefore, the evaluation phase is the most appropriate stage to determine the success of the interventions in reaching the specified goal.

Correct Answer: A

Rationale: The correct answer is A. Public health focuses on preventing disease, promoting health, and protecting populations through a population-based approach. This involves addressing social determinants of health, implementing interventions at the community level, and working towards health equity. Choice B is incorrect because it describes the provision of health care services in various settings, not specifically focused on population health. Choice C is incorrect as it refers to health care services provided in community institutions, not necessarily focused on population health. Choice D is incorrect as it describes the nursing process and evidence-informed practice, which are important in healthcare delivery but not specific to the broad scope of public health.

Correct Answer: B

Rationale: Health promotion is distinct from health protection because it focuses on empowering individuals to have increased control over factors influencing their health. This includes education, lifestyle changes, and creating supportive environments. Choice A is incorrect as quality of care is not the primary focus of health promotion. Choice C is incorrect as health promotion is not limited to the delivery of care by healthcare providers. Choice D is incorrect as health promotion is broader than just social marketing campaigns, encompassing a range of strategies to improve health outcomes.

Correct Answer: D

Rationale: The correct answer is D: Commentator. This role involves tracking group process in writing and providing information to the group. A Coordinator focuses on organizing tasks, an Encourager offers positive reinforcement, and an Orienter sets the direction for the group. Commentator's role aligns closely with tracking and conveying information, making it the most suitable choice.

Correct Answer: B

Rationale: The correct answer is B because limited knowledge can lead to pregnancy complications in pregnant adolescents. Having adequate knowledge about prenatal care, nutrition, and potential risks is crucial for ensuring a healthy pregnancy. Incorrect choices: A: Not all adolescent pregnancies are high risk. Risk factors vary based on individual circumstances. C: While some pregnant adolescents may struggle with proper nutrition, it is not a general rule. D: Socioeconomic status can influence health outcomes, but it is not the most important factor in caring for pregnant adolescents.
