Final answer:
To be a federal pharmacist, one must indeed have a license in the US state or territory where they practice, as pharmacists must hold a doctorate in pharmacy and meet state-specific licensure requirements. This includes passing examinations and adhering to continuing education stipulations.
Step-by-step explanation:
The statement that to be a federal pharmacist, one must maintain a license in the US state or territory in which they'll be practicing is true. This is because pharmacists must adhere to the laws and regulatory systems set forth by the state in which they work. In the United States, a pharmacist is required to hold a doctorate in pharmacy, commonly referred to as a PharmD, from an accredited pharmacy school and must be licensed by the state. This licensure involves passing the North American Pharmacist Licensure Examination (NAPLEX) and, in most cases, the Multi-State Pharmacy Jurisprudence Exam (MPJE) or a state-specific equivalent. It is this license that assures the public that the pharmacist has met specific standards to practice pharmacy and dispense medications within the state.
Furthermore, to maintain their license, pharmacists usually need to complete continuing education requirements and adhere to ethical and professional standards dictated by the state's pharmacy board. Without state licensure, a pharmacist cannot legally practice in that state, whether it is in a drugstore, hospital, or as a federal pharmacist.
