4. After discussing the possible effects of the low patient satisfaction rate, the staff started to list
- A. Collaboration
- B. Majority rule
- C. Dominance
- D. Compromise
Correct answer: B
Rationale: The correct answer is B: 'Majority rule.' In this scenario, the staff is likely listing potential solutions or actions based on the opinion or agreement of the majority. Collaboration (A) involves working together towards a common goal, while Dominance (C) implies one person or group having control. Compromise (D) suggests finding a middle ground between different viewpoints. Majority rule best fits the situation where a decision or list of actions is being determined by what most people agree on, which is a common approach in group decision-making processes.
