Which factor is a key limitation of solely using moral rules in ethical decision making?

• A. Cultural differences and lack of guidance for new situations
• B. They always fit every scenario
• C. They are universal across all cultures
• D. They eliminate the need for professional judgment

Answer: (A)

Relying on moral rules alone emphasizes duties, but clinical ethics unfolds in diverse cultures and evolving situations. A rule that seems clear in one context may clash with a patient’s values, local norms, or unique circumstances, leaving gaps when a case is novel or ambiguous. That’s why rule-based ethics can be rigid and require professional judgment to interpret the duty, weigh competing principles, and consider real-world outcomes for patient welfare. So, cultural differences and lack of guidance for new situations are the primary limitation of using moral rules by themselves. The other ideas—rules fitting every scenario, being universal across cultures, or eliminating the need for professional judgment—aren’t accurate in practice.
