Question

1. a 45 - year - old male with schizophrenia has been treated with haloperidol for 6 months. he presents with restlessness, pacing, and an inability to sit still. what is the most appropriate management? a. increase the dose of haloperidol. b. add benztropine. c. discontinue haloperidol and switch to clozapine. d. administer propranolol.

Explanation:

The patient is experiencing akathisia (restlessness, pacing, inability to sit still) which is a common side - effect of typical antipsychotics like haloperidol. Propranolol is an effective treatment for akathisia. Increasing the haloperidol dose would likely worsen the akathisia. Adding benzotropine is more effective for parkinsonian - type side - effects rather than akathisia. Switching to clozapine is a more drastic measure and not the first - line approach for managing this side - effect.

Answer:

D. Administer propranolol.
