Correct Answer: C

Rationale: By using expert power in the workplace, nurses increase their professional influence. Expert power is derived from an individual's knowledge, skills, or expertise in a particular area. This allows nurses to influence others based on their competence and credibility, rather than through political skills (choice A), reward power (choice B), or the combination of power and politics (choice D). While political skills and understanding power dynamics can be beneficial, expert power is particularly effective in enhancing a nurse's professional influence.

Correct Answer: B

Rationale: The correct answer is B, 'Extinction.' Extinction is a behavioral psychology technique where undesirable behavior is ignored, leading to its eventual decrease or elimination. This process involves withholding reinforcement that was previously maintaining the behavior. Choice A, 'Punishment,' involves applying negative consequences to reduce unwanted behavior, which is different from extinction. Choice C, 'Shaping,' is a method of gradually molding or reinforcing behaviors to reach a desired behavior, not ignoring negative behavior. Choice D, 'Equity,' refers to fairness and equal treatment, which is unrelated to eliminating negative behavior through ignoring it.

Correct Answer: B

Rationale: The correct answer is B, self-staffing. Self-staffing is the model where staff entirely manage staffing and scheduling themselves, without external involvement.

Management scheduling typically involves supervisors or managers creating and managing schedules for the unit.

Correct Answer: A
