Correct Answer: C

Rationale: The correct answer is C: Mental confusion. In this scenario, the client's high fever and pneumonia diagnosis indicate an infection. Infections, especially in older adults, can lead to mental confusion due to the body's systemic response to the infection. Flushed skin (choice A) is more commonly associated with fever but does not specifically relate to the client's condition. Bradycardia (choice B) and hypotension (choice D) are less likely findings in a client with pneumonia and a high fever; instead, tachycardia and increased blood pressure are more commonly seen in response to infection.

Correct Answer: C

Rationale: The DRG manual is used to determine the reimbursement rate for medical diagnoses and treatments under the prospective payment system used by healthcare facilities. Choice A is incorrect because the DRG manual is not used to classify nursing diagnoses, but rather to group medical diagnoses for billing purposes. Choice B is incorrect as the DRG manual is not used to identify findings related to medical diagnoses, but rather to standardize payments for medical services. Choice D is incorrect as the DRG manual is not used to implement nursing care based on case management protocol, but rather to set reimbursement rates.

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: 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: A

Rationale: The most important information for the nurse to obtain before initiating a community health program targeting teenage smoking is the incidence of smoking among the teenage population in the community. Understanding the prevalence of smoking will help in designing effective intervention strategies. Choice B about funding, while important, is secondary to understanding the scope of the issue. Choice C, the target objectives from Healthy People 2020, may provide guidance but are not as crucial as knowing the local prevalence. Choice D, satisfaction data from previous programs, does not provide essential information for planning a new program.
