Final answer:
To find out how many 0.5 mg tablets of benztropine make up a 3.5 mg dose, divide the total dose by the dosage per tablet. The nurse should administer 7 tablets per dose.
Step-by-step explanation:
The question asks us to calculate the number of tablets a nurse should administer per dose for a client with Parkinson's disease who is prescribed benztropine 3.5 mg PO twice daily, with each tablet containing 0.5 mg of the medication.
To solve this, we divide the total dose needed (3.5 mg) by the amount per tablet (0.5 mg):
3.5 mg รท 0.5 mg/tablet = 7 tablets.
Therefore, the nurse needs to administer 7 tablets per dose. The correct answer is c) 7.
