Final Answer:
The nurse should administer a PRN dose of benztropine (Cogentin) when the client exhibits tremors and a shuffling gait.The correct option is C.) Upon experiencing tremors and shuffling gait.
Step-by-step explanation:
In the treatment of paranoid schizophrenia with chlorpromazine (Thorazine), extrapyramidal side effects (EPS) such as tremors and shuffling gait are common. Benztropine, an anticholinergic medication, is prescribed PRN to manage these EPS.
The nurse should administer benztropine when the client demonstrates these symptoms, as it helps counteract the effects of chlorpromazine on the central nervous system.
The suboptimal functioning of dopamine and acetylcholine in the brain contributes to EPS. Chlorpromazine, an antipsychotic, primarily blocks dopamine receptors, leading to an imbalance between dopamine and acetylcholine.
Benztropine, as an anticholinergic, helps restore this balance by inhibiting the effects of acetylcholine. Therefore, when the client experiences tremors and a shuffling gait, indicating an imbalance in neurotransmitters, the administration of benztropine is appropriate.
It's essential for the nurse to assess the client's symptoms accurately and administer benztropine only when the specific EPS are present.
Administering it for unrelated issues, such as constipation (Option D), would not address the underlying neurological imbalance and may expose the client to unnecessary medication. Thus, a targeted approach aligns with best practices in managing medication for mental health conditions.
The correct option is C.) Upon experiencing tremors and shuffling gait.
