Can a registered nurse inject Botox or filler in Hawaii?

Short answer
The cited rules do not settle this — they put the prescription and selection of therapeutic measures in APRN scope, which supersedes RN scope, and describe RN practice as carrying out a licensed prescriber's medical orders; no cited rule names Botox or filler.

The nursing act sections cited here describe each level of nursing and give the advanced practice registered nurse a scope of its own. Registered nurse practice is the full scope of nursing guided by the chapter, the board’s rules, and board-recognized standards, and includes carrying out prescribed medical orders of a physician, an advanced practice registered nurse, or a supervised physician assistant; licensed practical nurse practice is a directed scope under the direction of a registered nurse, advanced practice registered nurse, physician, or other authorized provider. An advanced practice registered nurse’s scope includes advanced assessment, telehealth, and the diagnosis, prescription, selection, and administration of therapeutic measures including legend drugs and controlled substances within the nurse’s role and certification, supersedes the registered nurse scope, and, once the board grants prescriptive authority, includes prescribing and administering legend drugs and controlled substances and dispensing manufacturers’ prepackaged samples of over-the-counter and non-controlled legend drugs, never controlled-substance samples; only a board-licensed advanced practice registered nurse may use that title. A physician assistant’s supervising physician must review a set share of the physician assistant’s medical records within thirty days during the first year and audit a sample for at least thirty minutes each month thereafter. None of the sections cited here mentions injectables, neuromodulators, or fillers by name.
