Final answer:
Option 3: "I will sit in the sun for an hour a day to enhance medication effectiveness." This statement is incorrect because sitting in the sun will not enhance the effectiveness of benztropine mesylate.
Step-by-step explanation:
The statement that indicates that the client needs further teaching about the medication is option 3: "I will sit in the sun for an hour a day to enhance medication effectiveness."
This statement is incorrect because sitting in the sun for an hour a day will not enhance the effectiveness of benztropine mesylate. Benztropine mesylate is a medication used to treat Parkinson's disease and certain side effects of antipsychotic medications, and its effectiveness is not affected by sunlight.
It is important for the client to have accurate information about their medication and its effects, so they should be taught that sitting in the sun will not enhance the effectiveness of benztropine mesylate.
