Correct Answer: C

Rationale: Individuals with cognitive impairment often experience difficulties in learning new information, creative thinking, and making sound judgments. Loss of ability in hearing, speech, and sight (Choice A) is more closely related to sensory impairments rather than cognitive impairment. Endurance, strength, and mobility (Choice B) are more associated with physical capabilities rather than cognitive functions. Balance, flexibility, and coordination (Choice D) are related to motor skills and physical coordination, not cognitive impairment.

Correct Answer: C

Rationale: Studying knowledge, attitudes, and practices of the people is the best method to determine appropriate health teaching for a community. This approach provides valuable insights into the specific needs, beliefs, and behaviors of the population, allowing for tailored and effective health education interventions. Interviewing midwives may offer some insights, but focusing on the broader community is more comprehensive. Reviewing records and reports can provide historical data but may not capture current community needs as effectively as studying current knowledge, attitudes, and practices. Reviewing health statistics is important but may not provide the detailed understanding of community perceptions and behaviors that directly impact health education planning.

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: B

Rationale: Identifying populations and individuals in need of healthcare services is essential when seeking funding for an outreach program. This criterion helps demonstrate the relevance and impact of the program on specific groups requiring healthcare services. Choice A is incorrect because while addressing multiple health problems is important, identifying the target population in need of services is more critical for funding considerations. Choice C is incorrect as evaluating variations in health services and status, though valuable, is not directly related to securing funding. Choice D is incorrect as offering services in various community locations is a component of the program's implementation, not a criterion for funding.

Correct Answer: A

Rationale: Lethargy is a critical finding that requires the nurse's immediate attention when a client with a recent skull fracture is readmitted to the hospital. It can indicate increased intracranial pressure or other serious complications such as hemorrhage or infection. Addressing lethargy promptly is crucial to prevent further deterioration. Agitation, ataxia, and hearing loss are important to assess but do not signify the same level of urgency as lethargy in this context.
