Correct Answer: C

Rationale: The correct answer is C. Shared governance in a nursing unit involves staff nurses and CNAs having autonomy and decision-making power in aspects like scheduling, which is reflected in them making their own schedules. This scenario aligns with the philosophy of shared governance where nursing practice is best determined by nurses. Choices A, B, and D do not exemplify shared governance as they involve hierarchical delegation, managerial decision-making, and seeking advice from superiors rather than autonomous decision-making by frontline staff.

Correct Answer: A

Rationale: An environment that rewards good performance is the goal in a work environment as it promotes productivity and motivation among employees. Rewarding performance leads to improved outcomes and helps in achieving organizational objectives. Choice B, 'Turnover,' is incorrect as turnover refers to the rate at which employees leave an organization, and it is not a goal to be rewarded. Choice C, 'Strategies,' does not directly relate to rewarding good behavior but rather focuses on plans or approaches to achieve goals. Choice D, 'Stress,' is not something that should be rewarded in a work environment; instead, it should be managed and reduced to promote employee well-being.

Correct Answer: D

Rationale: The statement 'Ethical principles can serve as the foundation for laws' is correct. Ethical principles act as a standard for evaluating actions and behaviors. While ethical principles may influence the creation of laws, they are not laws themselves. Choice A is incorrect as ethics are usually upheld through societal norms and personal values rather than government enforcement. Choice B is incorrect because laws do provide standards, but those standards are legal rather than ethical. Choice C is incorrect as ethics are broad guidelines for behavior, not highly detailed rules.

Correct Answer: A

Rationale: The correct answer is A: Measure the ankle-brachial index. This task involves using a Doppler ultrasound device to assess blood flow, which can be safely delegated to UAP. Choices B, C, and D require a higher level of assessment and interpretation that should be performed by licensed nursing staff. Checking for changes in skin pigmentation (B) and assessing for foot drop (C) involve more complex assessments that require nursing judgment. Asking about symptoms of depression (D) involves a psychosocial assessment, which should be performed by licensed personnel qualified to address mental health concerns.

Correct Answer: B

Rationale: The correct answer is B: 'Nursing ethics focus on the duties and rules of behavior for professional nurses.' Nursing ethics primarily revolve around the principles and standards that guide the actions and decisions of nurses in their professional roles. Choice A is incorrect as nursing ethics are not limited to the organizational level but extend to individual conduct. Choice C is incorrect as while moral character is important, nursing ethics encompass more than just character traits. Choice D is incorrect as nursing ethics are centered on professional responsibilities rather than personal experiences and needs.
