Which drug would a nurse anticipate being given with chlorpromazine to reduce extrapyramidal side effects?

There are choices for this question namely:

A) benztropine (Cogentin)

B) dantrolene (Dantrium)

C) clonazepam (Klonopin)

D) diazepam (Valium)

The correct answer is "Benztropine (Cogentin) ". The administration of the typical antipsychotic Chlorpromazine may cause side effects characterized as involuntary repetitive movements called tardive dyskinesia (extrapyramidal symptom). The drug Benztropine is an anticholinergic drug that blocks the action of acetylcholine (as well as dopamine) in the central nervous system, restoring the neurotransmitter homeostasis.
