Which of the following measures the proportion of the population that exhibits a particular disease at a particular time and includes both new and old cases?

Correct Answer: D

Rationale: The correct answer is D, prevalence ratio. Prevalence ratio measures the proportion of the population with a particular disease at a specific time, including both new and existing cases. Choice A, proportionate morbidity rate, is not a standard term and might confuse students. Choice B, case fatality rate, measures the proportion of deaths from a specific disease compared to the total number of cases but does not include both new and old cases. Choice C, incidence ratio, measures the rate of new cases of a disease in a specific population over a defined period, not considering existing cases.

Correct Answer: C

Rationale: Community health nurses are primarily responsible for coordinating emergency response efforts during disasters. This involves organizing and implementing strategies to address the health needs of the community in crisis situations. Providing direct patient care (Choice A) is often carried out by other healthcare professionals such as doctors and paramedics during disasters. Conducting research on disaster impacts (Choice B) is important for understanding the effects of disasters but is not the primary role of a community health nurse. Developing new healthcare policies (Choice D) is typically the responsibility of policymakers and public health officials rather than community health nurses.

Correct Answer: A

Rationale: The correct nursing approach in the immediate postoperative period for a cleft lip repair in an infant is to remove protective arm devices one at a time for short periods with supervision. This approach helps prevent injury to the surgical site while ensuring the infant's comfort and safety. Choice B is incorrect as initiating oral feedings immediately after surgery may not be appropriate and could compromise the surgical site. Choice C is incorrect as introducing parents to the suture line cleansing protocol is important but not the immediate priority. Choice D is incorrect as positioning the infant on the back after feedings is not specific to the immediate postoperative period for a cleft lip repair.

Correct Answer: D

Rationale: Correct! Community health nursing involves a broad scope of activities that focus on promoting and preserving the health of populations rather than individuals. This includes leading support groups, providing home care, and educating communities. The other options represent different aspects of nursing care such as home health nursing, wound care, and maternal-child health - which are not exclusive to community health nursing.

Correct Answer: B

Rationale: The correct answer is B: Glycosylated hemoglobin (HbA1c). Glycosylated hemoglobin provides valuable information about blood glucose control over the past 2-3 months. This test measures the average blood sugar levels during this period, offering a more comprehensive view of long-term glycemic control. Choice A, blood glucose level, reflects the blood sugar concentration at the time of testing and may fluctuate throughout the day. Choice C, urine ketones, indicates the presence of ketones and is more relevant for assessing acute complications like diabetic ketoacidosis. Choice D, serum insulin level, evaluates insulin production and is not a direct indicator of long-term blood glucose control in diabetes management.

Correct Answer: B

Rationale: The most important referral for the nurse to make for the elderly, recently widowed female client who had a mild stroke and limited mobility is Meals-on-Wheels. This service will ensure she receives proper nutrition and support given her circumstances. Pastoral care may provide emotional and spiritual support but is not as essential in this scenario. Grief support group could be beneficial but addressing her nutritional needs takes precedence. Physical therapy may be important for rehabilitation but ensuring proper nutrition is more critical at this time.

Correct Answer: B

Rationale: When helping a family decide on actions to take, it is essential to identify the courses of action available to them and the resources needed for each. This empowers the family to make informed decisions based on their specific situation. Explaining the consequences of inaction (Choice A) may be necessary but does not provide a range of options. Discussing the consequences of each course of action (Choice C) is important but does not actively guide the family on the available actions. Influencing the family (Choice D) to act based on personal judgment undermines their autonomy and may not lead to the best outcome.

Correct Answer: B

Rationale: In this scenario, the community activities described focus on supporting and promoting overall well-being, which aligns with the concept of health protection. Choice A, disease prevention, is incorrect as the activities are more about supporting health rather than preventing specific diseases. Choice C, risk management, does not fit as the activities are not primarily about managing risks. Choice D, health balance, is not the most appropriate choice as the activities are aimed at protecting and enhancing health rather than achieving a balance.

Correct Answer: B

Rationale: The correct answer is B: conducting exercise classes at the community center. Regular physical activity plays a crucial role in preventing Type 2 diabetes by helping to maintain a healthy weight, improve insulin sensitivity, and regulate blood sugar levels. Distributing brochures (choice A) may raise awareness but might not lead to significant behavior change. Providing free glucose monitors (choice C) focuses on monitoring rather than prevention. Offering dietary counseling sessions (choice D) is important but focusing solely on diet may not address the comprehensive approach needed to prevent Type 2 diabetes.
