Final answer:
The dentist writes the age of the patient in the prescription to aid the pharmacist in checking for the appropriate dose.
Step-by-step explanation:
The statement is correct but the reason is not. The dentist writes the age of the patient in the body of the prescription to help the pharmacist check for any potential drug interactions or contraindications that may be specific to certain age groups. This information is important for the pharmacist to ensure that the prescribed dose is appropriate for the patient's age and overall health condition.
