Final answer:
As a new graduate in Iowa, you cannot prescribe controlled substances without obtaining a DEA number. Licensure and being granted prescriptive authority for controlled substances involves specific processes beyond state licensing.
Step-by-step explanation:
The statement is False. As a new graduate, you do not automatically have the ability to prescribe controlled substances.
Even if you have obtained your professional state license in Iowa as a nurse practitioner or physician assistant, for instance, you still must apply for a separate DEA (Drug Enforcement Administration) number, which grants the authority to prescribe these substances. The process involves several steps including background checks and may vary depending on your specific profession within healthcare.
It's important to understand both federal and state requirements, as they can differ from one state to another and from one profession to another.
