Answer 1

The validity of prescriptions depends on their CSA schedule. CII prescriptions are valid for 90 days without refills. CIII and CIV have a 180-day validity with possible refills, and CV can be valid for up to 365 days with refills. None of the provided options match these periods exactly.

Step-by-step explanation:

The validity period of prescriptions for controlled substances varies depending on their classification under the Controlled Substances Act (CSA). For CII (Schedule II) drugs, a written prescription is generally valid for 90 days after the date of issuance. Refills of CII medications are not permitted; a new prescription is required for each issuance. For CIII and CIV (Schedule III and IV) drugs, prescriptions are valid for 6 months or 180 days from the date of issuance, with the option for up to five refills within this period. Lastly, CV (Schedule V) prescriptions may be valid for one year or 365 days, depending on state laws, with refills as authorized by the prescriber.

Applying this information to the provided options, none of the answer choices exactly match the typical prescription validity periods as outlined above. Thus, it is essential for the student to verify the current rules with their state's regulations or the DEA guidelines, as these might vary slightly or change over time.
