Correct Answer: A

Rationale: The correct answer is A: Key informant interview. Ms. Nena will use this method to gather in-depth information from knowledgeable individuals within the community. This approach allows her to gain insights and perspectives from key stakeholders, such as the primary grade teacher and barangay official, who have first-hand knowledge and experience. Key informant interviews are particularly useful for obtaining specific details, opinions, and insights that may not be easily accessible through other methods. In contrast, participant observer involves direct participation in community activities, community mapping focuses on spatial data collection, and social survey typically involves collecting data from a larger sample size rather than individual key informants.

Summary: Choice C is correct as it exemplifies incongruent communication, while Choices A, B, and D are incorrect as they describe congruent messages.

Correct Answer: C

Rationale: The correct answer is C because independence for the elderly means they have the freedom to make choices and decisions about their own lives. This empowers them to live according to their preferences and values. Choice A is incorrect because it doesn't consider individual circumstances; choice B is important but doesn't capture the essence of independence; choice D is too broad and doesn't specifically address the concept of personal autonomy and agency for the elderly.

Correct Answer: B

Rationale: The correct answer is B: establish a credit body of evidence to support and improve the delivery of care. Conducting research in nursing aims to generate a robust evidence base to inform and enhance the quality of care provided to patients. This evidence helps in identifying best practices, improving patient outcomes, and advancing the nursing profession as a whole. Choice A is incorrect because the main goal of research is not to solely justify the role of nurses, but rather to improve care delivery. Choice C is incorrect as the goal is not to justify an oversupply of nurses, but to address healthcare needs effectively. Choice D is incorrect because the focus of nursing research is on nursing-related issues, not non-nursing problems.

Correct Answer: C

Rationale: Step-by-step rationale for the correct answer (C: I and II): 1.

Choice II (Physiologically, all individuals experience pain in a similar manner) is correct because pain perception is largely influenced by biological factors that are universal. 3. Choice III (Some Asian people have a high response to pain medications) is incorrect as it focuses on a specific cultural group, which is not a general characteristic emphasized in culturally sensitive care. 4. Choice IV (Patients should be assessed for pain regardless of overt symptomatology) is incorrect as it is not specifically related to cultural sensitivity in pain management.
