Can a registered nurse inject Botox or filler in Wisconsin?

Whoever performs a delegated medical act in Wisconsin, the supervising physician remains answerable for it under the adequate-supervision test — which reaches licensed and unlicensed personnel alike. A nurse carrying out a delegated act is therefore working inside the physician’s duty, not outside it.

Wisconsin grants the physician assistant the act itself, in words that reach an injection directly. Subject to the limitations in subsection (2), and to the physician assistant’s own experience, education and training, a physician assistant may “Examine into the fact, condition, or cause of human health or disease, or treat, operate, prescribe, or advise for the same, by any means or instrumentality” and may “Penetrate, pierce, or sever the tissues of a human being.” On drugs the grant is equally direct: “consistent with his or her experience, education, and training”, “a physician assistant may order, prescribe, procure, dispense, and administer prescription drugs, medical devices, services, and supplies.”
