All suicidal patients are considered to lack capacity to understand.

• A. True
• B. False
• C. Depends on the patient
• D. Only when the patient expresses intent to harm themselves

Answer: (A)

Capacity to understand and make decisions is determined for each situation, not by a blanket label about a person’s mental state. What matters is whether the patient can understand the information relevant to a decision, appreciate how it applies to their own situation, reason about options, and communicate a clear choice. Suicidal thoughts by themselves do not automatically mean someone lacks this ability. A patient with suicidal ideation may still understand risks, benefits, and alternatives, and may be able to participate in decisions about treatment, including options like hospitalization or safety planning.

Only in cases where a mental condition, intoxication, delirium, or severe cognitive impairment undermines understanding, appreciation, reasoning, or communication would capacity be lacking for the specific decision. Therefore, capacity is not determined by the presence of suicidality alone; it depends on the individual and the particular decision at hand.
