Common questions
Which sections of the Mental Health Act are tested?
Those a Foundation doctor meets: section 5(2) (a doctor holding an informal inpatient), section 2 (assessment), section 3 (treatment) and section 136 (police). Questions ask which applies to a scenario.
Is alcohol withdrawal a mental health or a medical question?
Both appear on PLAB 1. In our bank, alcohol withdrawal, Wernicke encephalopathy and dependence sit in mental health, which matches the substance-misuse topics in the MLA content map.
