Risk pitfalls and guardrails
Equating mental illness or an unwise decision with incapacity, or applying the wrong UK legal framework.

Selecting an option that is true in isolation but does not best answer the exact clinical task.
Guardrail: Do not interpret a visual pattern without the modality, clinical context and the exact task in the stem.
