Answer 1: (e) None of the above.
Typical Antipsychotics should be avoided in above mentioned conditions.

Patient presented to ED with shakes, body ache, hallucination and history of drinking unknown amount of alcohol: This patient is in alcohol withdrawal, and use of typical antipsychotics will increase the risk of seizure.

Patient presented to ED with Phencyclidine (PCP) intoxication: additive anticholinergic effects of PCP and typical antipsychotics. Benzodiazepines should be used.

Patients with rigid form of Huntington's disease: Pt may experience acute EPS.

Answer 2: (b) Epinephrine

Hypotension is produced by alpha adrenergic blockage property of typical antipsychotics, & these drugs also block the alpha adrenergic stimulating property of epinephrine, leaving beta adrenergic stimulating property untouched. As a result epinephrine will cause paradoxical worsening of hypotension and hence epinephrine is contraindicated in antipsychotic induced hypotension.
