Rhode Island Multistate Pharmacy Jurisprudence (MPJE) Practice Exam

The correct response highlights that for prescriptions categorized under Schedule III to V, the maximum allowable supply duration is indeed 90 days. This regulation aligns with federal law, which stipulates that a prescription for controlled substances in these schedules can be refilled within a timeframe that does not exceed 90 days from the date of the original prescription. This provision ensures that patients receive adequate therapy while allowing for a reasonable amount of medication to be dispensed at one time.

In contrast, the other options reflect shorter durations that do not meet the established federal guidelines, limiting the ability of patients to access their required medications for longer-term treatments or for chronic conditions that necessitate consistent management with controlled substances. Recognizing the 90-day limit helps pharmacists properly manage prescriptions and ensures compliance with legal requirements regarding controlled substances. This understanding is essential in pharmacy practice to safeguard patient care while adhering to statutory regulations.
