A charge alone does not end a California nursing license, but a conviction can lead to discipline. The Board of Registered Nursing requires registered nurses to report most convictions within 30 days, though not an arrest without a conviction. Discipline based on a conviction requires a crime substantially related to nursing, but the Board can also act on underlying conduct, such as dangerous drug or alcohol use, without a conviction.

What you actually have to report, and when

The Board of Registered Nursing requires a licensee to report, within 30 days of occurrence, any conviction in any state, a United States territory, a military court, or another country, including a plea of no contest, according to the Board's own conviction reporting guidance. It covers misdemeanors and felonies, and infractions too, except that the Board says an infraction with a fine of less than $1,000 does not need to be reported unless it involved alcohol or controlled substances. The same guidance also requires reporting discipline taken against you by another licensing agency within the same 30 day window, which is easy to overlook if you hold more than one credential or license in a different field. These are Board of Registered Nursing rules for registered nurses; the Board's enforcement page notes that vocational nurses and nursing assistants are regulated by other agencies, such as the Board of Vocational Nursing and Psychiatric Technicians, which have their own requirements.

Does an arrest alone have to be reported

No. The Board's own guidance states that an arrest only has to be reported if it results in a conviction. An arrest that is never charged, or a charge that is dismissed outright, generally does not trigger the 30 day reporting duty by itself. Watch the actual disposition of your case closely, since the clock starts from the conviction, not the arrest date, and a charge can sit open for months before it resolves one way or the other, which makes it easy to lose track of exactly when your 30 days actually begin.

Business and Professions Code section 2761(e) allows discipline for a conviction of a felony or of any offense "substantially related to the qualifications, functions, and duties of a registered nurse," and section 490 limits every California board's conviction-based discipline to crimes substantially related to the licensed profession. The Board's regulation, 16 CCR 1444, directs it to weigh the nature and gravity of the offense, the years since it happened, and the duties of a registered nurse. Its list of substantially related crimes and acts includes theft, dishonesty, fraud, or deceit; child, elder, or dependent adult abuse; registerable sex offenses; assault, battery, or other violence; use of drugs or alcohol in a dangerous manner; harassment, trespass, or stalking; and failure to comply with mandatory reporting requirements. The firm's answer on nurses facing domestic violence charges looks at one of those categories in detail. An offense outside the listed categories, such as a minor traffic offense with no alcohol or drug element, raises a different question, but the Board still applies the same criteria to the facts.

Does a dismissal or expungement style order change anything

Not automatically. Business and Professions Code section 2765 lets the Board act on a conviction irrespective of a later order under Penal Code section 1203.4 allowing you to withdraw the plea, setting aside the verdict, or dismissing the case. Separately, section 492 says completing a diversion program does not stop a licensing board from disciplining a licensee for professional misconduct, even when the evidence of it appears in an arrest record. The Board's own reporting page says convictions "set aside or deferred pursuant to Section 1000 or 1203.4 of the Penal Code" must still be reported (Penal Code section 1000 covers drug diversion). A later dismissal can still matter to the Board's decision about discipline, but it does not erase the reporting duty or guarantee the conviction will be ignored.

What the Board's disciplinary process actually looks like

A reported conviction, or one the Board learns about another way, typically starts with an investigation by the Board's own investigators or the Department of Consumer Affairs' Division of Investigations, who gather records and statements and report their findings back to the Board. If the Board believes discipline is warranted, the matter goes to the Attorney General's Office, which can prepare a formal accusation listing the specific charges. You get an opportunity to dispute the charges at an administrative hearing that, in the Board's words, "closely resembles a court trial," after which an administrative law judge writes a proposed decision and the Board makes the final decision; a case can also be resolved by a stipulated agreement instead of a hearing. Possible outcomes range from a citation and fine, to license probation with specific conditions monitored by a Board probation monitor, to suspension, revocation, or an accepted voluntary surrender; a nurse who completes probation successfully has the license restored without restriction. The report itself also matters: the Board's guidance says failing to disclose all or part of your convictions may be grounds for discipline on its own.

What to do before your 30 days run out

Mark the conviction date, not the arrest date or the date you plan to appeal, and count 30 days from there. Gather the exact charge, the court, and the disposition in writing before you contact the Board. Its reporting page asks for a written explanation of the circumstances, arrest documents such as the police report, court documents such as the complaint and sentencing order, and any mitigating or rehabilitation evidence, so get advice on how the report should be framed, since the self-report becomes part of your file either way. Keep your own copy of exactly what you submitted and when, separate from whatever the Board keeps, in case a later question arises about timing. The firm's page on DUI and professional licenses in California and the broader overview of how a conviction affects professional and DMV licenses cover related consequences beyond nursing specifically.
