Correct Answer: B

Rationale: The correct answer is B. The low magnesium level and elevated creatinine suggest possible renal dysfunction, which is concerning, especially in a pregnant client with multiple risk factors such as morbid obesity, asthma, and hypertension. Immediate attention is needed to address the potential renal issues. The other choices do not indicate such urgent conditions. Hemoglobin and calcium levels in choice A are within acceptable ranges. Choice C shows elevated blood urea nitrogen and glucose levels, which may need monitoring but not immediate attention. Choice D's hematocrit and platelet levels are also within normal ranges and do not indicate an urgent issue.

Correct Answer: C

Rationale: Achieving optimal health for a community involves multiple factors and indicators. For a public health nurse to begin achieving this goal, it is essential that all relevant indicators are present, not just one or a few. While choices A, B, and D are important components of promoting community health, optimal health for a community encompasses a comprehensive approach where all indicators are considered and addressed. Therefore, the correct answer is C.

Correct Answer: D

Rationale: In this situation, the nurse should first stabilize the client's neck to prevent potential spinal cord injuries. Logrolling the client or performing other assessments should only be done after ensuring spinal stabilization. Opening the airway immediately is important in cases of airway obstruction, but stabilizing the neck takes priority in this scenario. Performing a complete neurological assessment may delay immediate stabilization, which is crucial in suspected spinal injuries.

Correct Answer: D

Rationale: The correct answer is 'D: education.' Education plays a vital role in primary prevention strategies by empowering individuals with knowledge and skills to prevent the onset of diseases. Through education, people can make informed decisions about their health, adopt healthy behaviors, and engage in preventive measures. Choice A, 'aggressive interventions,' is incorrect as primary prevention focuses on proactive measures to avoid the development of diseases rather than aggressive reactive interventions. Choice B, 'detection,' is more aligned with secondary prevention, which involves early identification of diseases. Choice C, 'culture,' while important in shaping health behaviors, is not a key component specifically in primary prevention strategies.

Correct Answer: B

Rationale: The correct answer is B: listing supervisory activities. When preparing a supervisory plan, the Public Health Nurse (PHN) needs to list the specific supervisory activities that need to be carried out. This helps in organizing and outlining the tasks that need to be accomplished to ensure effective supervision. Choices A, C, and D are incorrect because although needs assessment, identifying training needs, and formulating objectives are important aspects of supervisory planning, they are not specifically related to the act of preparing a detailed list of supervisory activities.
