# California Law and Ethics practice questions: Emergency treatment

Five original California Law and Ethics practice questions on emergency treatment, each answered on this page with a rationale and a source.

Last updated: 2026-09-29.

## Question 1

During an IV moderate-sedation case, a patient develops laryngospasm; the team manages the airway and EMS transports her to the emergency department, where she recovers fully. The dentist asks the front office to "note it for the renewal file." What does BPC §1680(z) require?

- A. No report, because the transfer was the expected management of a recognized sedation complication.
- B. A written report to the Dental Board within 7 days of the unscheduled removal.
- C. A report within 30 days, the standard clock for all Board-reportable events.
- D. Disclosure on the next biennial license renewal application, and nothing more.

**Answer B:** A written report to the Dental Board within 7 days of the unscheduled removal.

BPC §1680(z) requires a written report within 7 days for an unscheduled removal to a hospital or emergency center for medical treatment after moderate sedation, deep sedation, general anesthesia, or the listed pediatric sedation. The trigger here is the qualifying removal after listed sedation—not sedation by itself.

**Common trap:** a scheduled hospitalization remains excluded; 30 days is the separate criminal-conviction-reporting clock.

## Question 2

Dr. Lin operates a solo private practice and decides to take a two-week vacation. She changes her office voicemail to state: "You have reached Dr. Lin's office. We are currently closed for vacation and will return in two weeks. If you are experiencing a medical emergency, please hang up and dial 911." On Saturday, an established patient experiences severe post-operative swelling and bleeding from an extraction performed by Dr. Lin earlier that week. According to the ADA Principles of Ethics and Code of Professional Conduct, how should Dr. Lin's voicemail instructions be evaluated?

- A. They are acceptable, because 911 is the safest universal route for any dental emergency after hours.
- B. They are unacceptable, because she made no reasonable emergency arrangement for patients of record.
- C. They are acceptable, because the duty to provide emergency access pauses during a documented vacation.
- D. They are unacceptable only because the voicemail failed to state the date of Dr. Lin's return.

**Answer B:** They are unacceptable, because she made no reasonable emergency arrangement for patients of record.

Under ADA Code Section 4.B (Emergency Service), a dentist must make reasonable arrangements for the emergency care of established patients. Delegating all after-hours dental complications to a generic 911 dispatch without providing a specific dental referral path or a covering colleague's contact information fails this ethical duty.

**Common trap:** Assuming that directing patients to 911 acts as a universal, acceptable legal shield for after-hours dental coverage.

## Question 3

A frantic walk-in patient arrives at a dental clinic at 4:30 p.m. clutching their jaw, stating they fell off a bicycle and shattered a front tooth. The patient has never been to this clinic before. The dentist is currently finishing a complex procedure in another room but wants to expedite the walk-in patient's triage safely. Under the California Business and Professions Code, what is the most legally appropriate action the dentist can take before personally examining the patient?

- A. Direct a dental auxiliary to expose emergency radiographs of the injured area before any dentist examination.
- B. Have the front desk complete a medical and dental history form, which establishes patient-of-record status.
- C. Nothing; no clinical action of any kind may occur until the dentist completes a formal oral examination.
- D. Direct an auxiliary to place a temporary splint on the fractured tooth while the dentist finishes the other procedure.

**Answer A:** Direct a dental auxiliary to expose emergency radiographs of the injured area before any dentist examination.

BPC §1684.5 generally prohibits treatment before the patient satisfies all four patient-of-record elements, but expressly allows an auxiliary to expose emergency radiographs at the dentist's direction before any dentist examination. A preliminary oral examination alone does not establish patient-of-record status; the dentist must also evaluate the medical and dental history, diagnose the oral conditions, and develop a written plan.

**Common trap:** Believing that absolutely no auxiliary action—even diagnostic X-rays—can occur until the dentist officially completes a full medical history and formal examination, or extending the narrow radiograph exception to actual treatment such as splinting.

## Question 4

Dr. Hughes is performing complex endodontic treatment on an established patient. Midway through the procedure, the patient becomes highly agitated, verbally abuses Dr. Hughes, and refuses to keep their mouth open. Dr. Hughes loses his temper, places a temporary filling, and tells the patient, "We are done. You are dismissed from this practice permanently. Do not ever return here." He provides no written notice or referral. Under California law, this action constitutes:

- A. A lawful dismissal, because the patient's abusive conduct terminated the doctor-patient relationship.
- B. A lawful dismissal, because the temporary filling left the tooth at a clinically safe stopping point.
- C. Unprofessional conduct for abandonment, because he gave no written notice before discontinuing care.
- D. A private contract dispute between dentist and patient, with no Dental Board implications.

**Answer C:** Unprofessional conduct for abandonment, because he gave no written notice before discontinuing care.

BPC 1680(u) strictly defines patient abandonment. To legally sever the relationship, a dentist must provide written notice, allow ample time for the patient to find another provider, and ensure the patient's health is not jeopardized by the discontinuation. Dismissing a patient mid-treatment for an acute issue violates these requirements.

**Common trap:** Believing that a patient's abusive or non-compliant behavior instantly voids the dentist's legal requirement to provide safe transitional care and written notice.

## Question 5

On a Tuesday morning, a patient undergoes a routine scaling and root planing procedure under local anesthesia. Immediately following the procedure, the patient experiences a severe anaphylactic reaction to the anesthetic. The dentist calls 911, and the patient is transported to the local hospital emergency center, where they are admitted overnight for observation. The patient fully recovers and is discharged the next day. What is the dentist's administrative obligation regarding this incident?

- A. No report is required, because the patient fully recovered and was discharged within 24 hours.
- B. The dentist must report the transfer in writing to the Dental Board within 7 days.
- C. The dentist must report the incident to the Board within 30 days under the licensee reporting rule.
- D. The dentist must disclose the incident to the Board at the next biennial license renewal.

**Answer B:** The dentist must report the transfer in writing to the Dental Board within 7 days.

BPC §1680(z) mandates a written report within seven days for an unscheduled removal to a hospital or emergency center for medical treatment as a result of dental treatment. The Board's reporting notice confirms the event and deadline. A scheduled hospitalization is excluded, and a removal that is the normal or expected treatment for the dental condition is excluded only when none of the listed sedation or anesthesia was administered. An anaphylactic reaction requiring emergency transport is not normal treatment for the underlying dental condition.

**Common trap:** Thinking the mandatory 7-day reporting rule only applies to deaths or incidents involving general anesthesia/conscious sedation, or confusing it with the separate 30-day clock for reporting criminal convictions under 16 CCR §1018.05.
