3. Stephanie delegates effectively if she has authority to act, which is BEST defined as:

• A. having responsibility to direct others
• B. being accountable to the organization
• C. having legitimate right to act
• D. telling others what to do

Correct answer: A

Rationale: The correct answer is A: 'having responsibility to direct others.' Effective delegation involves entrusting tasks and responsibilities to others while still maintaining ultimate accountability. Authority to act means having the responsibility to direct others, making decisions, and overseeing the completion of tasks. This definition aligns with the core concept of delegation, where individuals are empowered and authorized to carry out specific duties. Being accountable to the organization (option B) is important but does not fully capture the proactive nature of delegation. Having a legitimate right to act (option C) is essential for effective delegation, but it is more about the formal authorization rather than the active responsibility to direct others. Simply telling others what to do (option D) is a narrow and authoritarian view of delegation that does not encompass the collaborative and empowering nature of effective delegation.

Rationale: The correct answer is B: 'system used to deliver care.' When a staff member suggests reviewing the pattern of nursing care being used, they are referring to the overall system or method in place for delivering care to patients. This includes the processes, protocols, and techniques used to provide nursing care. It goes beyond just following a job description, manual of procedure, or rules. By evaluating and potentially revising the system used to deliver care, staff can ensure that best practices are in place to provide high-quality and effective care to patients.
