Correct Answer: A

Rationale: The correct answer is A because it describes a cultural belief that attributes a physical trait (cleft lip) to a specific biological event (exposure to an eclipse during pregnancy). This choice demonstrates a cultural phenomenon based on biologic variation. Choice B is incorrect because it attributes denser bones in blacks to less morbidity from osteoporosis, which is a generalization and not necessarily a cultural phenomenon. Choice C is incorrect as it describes a family dynamic related to healthcare decision-making and not a cultural belief based on biologic variation. Choice D is incorrect as it describes a family tradition related to feasting and decision-making, which does not directly involve biologic variation.

Correct Answer: B

Rationale: The correct answer is B because it demonstrates empathy by acknowledging and validating the spouse's feelings of anger. By stating, "I understand how you could feel angry about the diagnosis," the nurse shows compassion and understanding towards the spouse's emotional response. This response helps to build trust and rapport with the patient's spouse during a difficult time. Choice A is incorrect as it focuses more on providing information rather than acknowledging the spouse's emotions. Choice C is incorrect as it does not address the spouse's feelings of anger and is not relevant to the situation. Choice D is incorrect as it comes across as confrontational and may make the spouse feel defensive.

Correct Answer: B

Rationale: The correct answer is B: active listening. Active listening involves fully focusing on the speaker, making eye contact, acknowledging what they are saying, and showing genuine interest in their words. In this scenario, the nurse is attentively listening to the patient's account of the events leading to chest pain, demonstrating active listening skills by being present in the moment and engaging with the patient's narrative. A: Assertive communication involves expressing one's thoughts and feelings clearly and respectfully. This choice is incorrect because the nurse is not actively expressing her thoughts or feelings in this situation. C: Empathy involves understanding and sharing the feelings of another. While empathy is important in nursing care, the nurse in this scenario is primarily engaged in listening rather than specifically expressing empathy. D: Passive communication is characterized by a lack of assertiveness and active engagement in the conversation. This choice is incorrect because the nurse is actively listening and engaging with the patient's narrative.

Correct Answer: A

Rationale: The correct answer is A: the legal definition of standard of care. In healthcare, the standard of care refers to the level of care that a reasonably prudent healthcare professional would provide in similar circumstances. Checking potassium level and pulse before administering a drug is considered standard practice to prevent adverse reactions. The nurse's testimony is based on this standard of care requirement to ensure patient safety and avoid potential harm. Choices B, C, and D are incorrect because they do not directly relate to the concept of standard of care in healthcare practice. B pertains to patient consent, C to the doctrine of "the thing speaks for itself," and D to immunity from liability for certain actions.

Correct Answer: C

Rationale: The nurse's communication style of working independently, sharing ideas with the team, and suggesting a collaborative approach aligns with Generation X characteristics. Generation X values independence, work-life balance, and collaboration. Baby Boomers (A) tend to be more hierarchical, Traditionalists (B) prioritize loyalty and respect for authority, and Millennials (D) are known for their tech-savvy and collaborative nature, but the nurse's approach best fits Generation X.
