Practice Protocol for Registered Nurses in California
Registered Nurses practice independently in California. A practice protocol is voluntary; here is what one covers and what the state does require.
FULL for general nursing scope (Bus. & Prof. Code §2725) — no physician-supervision requirement for baseline RN practice. SUPERVISED_ONLY carve-out for medical-aesthetic delegation (Botox/fillers/laser): treated as a delegated medical act, not baseline RN scope, per Medical Board of California guidance and 16 CCR §1364.50.
What a voluntary Registered Nurse protocol covers in California
California requires no written protocol for registered nurses. These are the clauses a practice includes when it chooses to put one in writing. The California Board of Registered Nursing governs registered nurses here.
The Registered Nurse ("RN") shall practice under the orders of the Physician and, where applicable, under standardized procedures developed collaboratively by Practice administration and health professionals, including the Physician and the Registered Nurse, as authorized under Business and Professions Code § 2725(c) and Title 16, California Code of Regulations §§ 1470–1474. The Physician shall be available to the Registered Nurse for consultation regarding clinical and patient care issues arising under any such order or standardized procedure.
- A voluntary protocol also carries 2 scope, 2 education and 2 registration clauses, authored in the document itself.
What California does require
The supervision and prescribing rules that apply to registered nurses regardless of any protocol.
Proximity
physician-delegated elective cosmetic procedure using a laser or intense pulsed light device: Available remotely (no on-site requirement)
16 CCR §1364.50 (confirmed verbatim via direct fetch): the delegating physician need not be on-site but must be 'immediately available' — defined as 'contactable by electronic or telephonic means without delay, interruptible, and able to furnish appropriate assistance and direction throughout the performance of the procedure.' The regulation says 'licensed health care provider' generically rather than naming RNs by profession, though MBC's own Medical Spas guidance describes this standard as applying to RN-performed procedures.
Supervision ratio
Not codified — no cap on file
Chart review
Not codified
Meeting cadence
Not codified
Prescriptive authority
No agreement needed to prescribe · no controlled-substance authority
Confirmed: general RNs (non-APRN) have no independent prescriptive authority — §2725 ties medication administration to orders from a physician, dentist, podiatrist, or clinical psychologist.
Written agreement
Not required
Unconditional for general nursing practice. For medical-aesthetic delegation, a written delegation order/standardized procedure from a supervising physician is required — legal hook is 16 CCR §1474 (general standardized-procedure content rules) plus §1364.50 (physician-availability standard specific to laser/IPL). The Medical Board's own 'Medical Spas' guidance page confirms: medical-scope procedures 'must be owned by physicians,' and qualified personnel are limited to physicians, RNs under physician supervision, and PAs under physician supervision.
Practice ownership (corporate practice of medicine)
Licensee-only ownership required — An RN CANNOT own the medical-scope portion of a med-spa business outright (Bus. & Prof. Code §2400). Corp. Code §13401.5(a), CONFIRMED via direct fetch, allows RNs (among 15 listed allied professions) to hold shares in a MEDICAL professional corporation as a minority (≤49%) shareholder, capped further at not exceeding the number of physician shareholders — distinct from an RN wholly owning their OWN nursing-scope entity (fine for nursing services, not for medical services like injectables).
Corp. Code §13401.5(a)'s RN-inclusion and percentage structure are confirmed via a dedicated follow-up fetch, superseding the original secondary-sourced hedge (an early fetch attempt had incorrectly suggested RNs were absent from the list; two later, independent fetches confirmed they are included).

About California's rules
California's NPs reach genuine full independence (AB 890/SB 1451, ~6 years total) and CNMs need zero physician involvement for definitionally 'low-risk' pregnancy care — no hours threshold. NPs/PAs may also majority-own their own practice corporations (Corp. Code §13401.5), cutting against the assumption that CA's strict, actively-enforced CPOM regime (2026 AG settlements against Carbon Health, Aspen Dental) blocks all non-physician ownership. CRNA is order-based, not supervision-based. Esthetician laser use is a flat criminal misdemeanor — no delegation pathway exists.
