Correct Answer: A

Rationale: The correct definition of 'chain of command' is the hierarchy of authority and responsibility. This term refers to the order in which authority and power in an organization are wielded and delegated from top management to every employee at every level. Choice B, 'Relationship without authority,' is incorrect because the chain of command specifically involves authority and responsibility. Choice C, 'Activity directed through linear authority,' is not a precise definition of the chain of command, as it does not encompass the full scope of authority and hierarchy. Choice D, 'The tendency for people to perform as expected,' is unrelated to the concept of the chain of command.

Correct Answer: B

Rationale: The correct answer is B. The nurse manager is showing an effort to understand if you are coping with the demands of your new role as a nurse. This approach demonstrates empathy and concern for your well-being and professional development. Choices A, C, and D are incorrect because there is no indication of intrusion, intimidation, or authoritarian behavior in the manager's actions. Instead, the manager is engaging in supportive and constructive communication to help you adjust and grow in your new position.

Correct Answer: D

Rationale: The correct answer is D. An ethical dilemma in nursing involves deciding whether to comply with a patient's request that conflicts with professional ethics, balancing competing values and principles. Choices A, B, and C do not directly represent ethical dilemmas in nursing. Choice A describes a general ethical dilemma, choice B involves professional conduct rather than a dilemma, and choice C refers to a confidentiality issue rather than conflicting ethical principles.

Correct Answer: D

Rationale: The correct answer is D, 'Diagnostic procedure.' When a client experiences an air emboli leading to a stroke during an IV start, it falls under the category of a diagnostic procedure risk. This incident occurred during a procedure intended for diagnosis or evaluation. Choices A, B, and C are incorrect. Patient dissatisfaction refers to a client's discontent with care, service, or outcomes; a medical-legal incident involves legal issues related to healthcare practices; and a medication error pertains to mistakes in medication administration.

Correct Answer: D

Rationale: The correct answer is D: 'You can delegate only those tasks.' Delegation in nursing involves transferring responsibility for the performance of a task while retaining accountability for the outcome. The principle of delegation does not require a situation with clearly defined superiors (choice A). Delegation can exist not only with a subordinate but also with colleagues or other healthcare team members (choice B). Delegation is not exclusive to nurses and is a tool used by various healthcare professionals (choice C). Therefore, the best choice is D as it accurately reflects the principle of delegation in nursing.
