This is typically a substituted decision, but not the legal basis for involuntary admission, which requires meeting legal criteria like dangerousness.

C. a person exhibiting behavior that is dangerous to themself or others is compelled into treatment regardless of their own desires:
Involuntary admission is based on risk of harm to self or others or inability to care for oneself due to mental illness.

D. a mother wants to admit her child for a fever and the doctor does not want the child admitted:
This is unrelated to mental health or involuntary psychiatric admission and refers instead to a disagreement over general medical care.

A. Paranoid delusions:
Delirium tremens (DTs) may cause paranoid or persecutory delusions.

B. Grandiosity:
Typically associated with mania or certain personality disorders, not alcohol withdrawal.

D. Tremors:
Tremors are a hallmark early sign of alcohol withdrawal and can persist into withdrawal delirium.

E. Visual hallucinations:
Alcohol withdrawal delirium often includes vivid visual (and tactile) hallucinations.
