Which item is part of assessing patient decision-making capacity?

• A. The patient's past medical history
• B. The patient's education level
• C. The patient's decision-making capacity is assessed by understanding, appreciation of consequences, reasoning, and ability to communicate a choice
• D. The patient's religious beliefs

Answer: (C)

Assessing a patient’s decision-making capacity hinges on four practical abilities: understanding information, appreciating how it applies to one’s own situation, reasoning about options, and communicating a clear choice. Understanding means grasping the relevant facts about diagnosis, prognosis, risks, benefits, and alternatives. Appreciation is recognizing how those facts relate to one’s own life and consequences. Reasoning involves weighing options, considering risks and benefits, and reflecting on personal values. Communication means being able to express a stable, voluntary decision.

Past medical history is important for overall care but doesn’t directly measure capacity. Education level might affect communication or understanding but does not determine true capacity. Religious beliefs can guide decisions but don’t define the cognitive ability to decide. Capacity is task-specific and can vary over time, so it must be assessed for the particular decision at hand.
