Final answer:
Benztropine is used to relieve the extrapyramidal symptoms caused by Chlorpromazine. It counteracts movement disorders by balancing neurotransmitter activity in the brain, specifically by reducing acetylcholine activity.
Step-by-step explanation:
The nurse should administer Benztropine to relieve extrapyramidal symptoms as an adverse effect of Chlorpromazine. Benztropine is an anticholinergic medication that can mitigate extrapyramidal side effects, which are movement disorders similar to those seen in diseases of the basal nuclei and involve the dopaminergic pathways.
Extrapyramidal symptoms can include muscle stiffness, tremors, bradykinesia, and dystonia. These symptoms are usually associated with antipsychotic medications, such as Chlorpromazine, due to their dopamine antagonism in the brain. Benztropine works by reducing the activity of acetylcholine in the central nervous system, which helps to balance the disrupted neurotransmitter activity.
It is important to note that while Benztropine is effective for this purpose, it would not be appropriate for treating adverse effects of Chlorpromazine such as respiratory depression, hypertension, or sedation. Understanding the correct indications for medications is critical in managing a patient's care effectively.
