A nurse is teaching about benztropine to a client who has schizophrenia. Which of the following statements should the nurse include in the teaching?
A.
“This medication is given to help with extrapyramidal side effects.”
B.
“Benztropine helps alleviate your hallucinations.”
C.
“This medication is given to help with your depression.”
D.
“Benztropine is used to counteract your tachycardia.”
The Correct Answer and Explanation is:
The correct answer is A. “This medication is given to help with extrapyramidal side effects.”
Explanation:
Benztropine is an anticholinergic medication commonly used to manage symptoms associated with extrapyramidal side effects of antipsychotic medications. Extrapyramidal side effects (EPS) are a group of symptoms that are similar to symptoms of Parkinson’s disease and can occur as a result of taking typical antipsychotics, which are used to treat schizophrenia. These symptoms include tremors, rigidity, bradykinesia (slowness of movement), and tardive dyskinesia (involuntary, repetitive movements).
- Mechanism of Action: Benztropine works by restoring the balance of neurotransmitters in the brain. It does this by blocking acetylcholine, a neurotransmitter that is often overactive in patients experiencing EPS. By reducing the effects of acetylcholine, benztropine helps to alleviate the motor symptoms associated with EPS.
- Not for Primary Schizophrenia Symptoms: Benztropine does not treat the core symptoms of schizophrenia, such as hallucinations, delusions, or disorganized thinking. These symptoms are managed by antipsychotic medications, such as risperidone or olanzapine. Benztropine is specifically used to address side effects that result from the use of antipsychotics.
- Not for Depression: Benztropine is not used to treat depression. Antidepressant medications or therapies are used for managing depression. Depression and schizophrenia may coexist, but benztropine does not address depressive symptoms.
- Not for Tachycardia: Benztropine is not used to manage tachycardia (rapid heart rate). Tachycardia management might involve beta-blockers or other medications, depending on the underlying cause.
In summary, benztropine is specifically indicated for managing extrapyramidal symptoms resulting from antipsychotic medications. It is not used to treat the primary symptoms of schizophrenia, depression, or tachycardia. This targeted use helps to ensure that patients experiencing EPS can better tolerate their antipsychotic treatment and maintain their overall treatment regimen.
