What are limitations of using moral rules in ethical decision making?

• A. Incomplete rules, cultural differences, and lack of guidance for new or unique situations
• B. They provide comprehensive universal guidance
• C. They replace professional judgment
• D. They always ensure the best outcome

Answer: (A)

Rules in moral decision making have limitations. They tend to be incomplete, leaving gaps for situations they didn’t anticipate or fully address. They also reflect the norms of a particular culture or institution, so differences in values or practices can change how a rule should be interpreted or prioritized. Most importantly, new or unique scenarios—such as novel imaging technologies or complex patient situations—may not be covered by any existing rule, requiring you to interpret the situation, weigh harms and benefits, and apply professional judgment. Because of these factors, moral rules don’t guarantee the best outcome; they provide a useful guide but must be integrated with context, reasoning, and professional judgment. The other statements imply that rules are universally applicable, replace judgment, or always yield the best result, which isn’t accurate.
