Question 1 of 15Informed Consent and Patient's Rights

An adult patient agrees to quadrant scaling and root planing after the dentist's diagnosis. The hygienist explains the procedure, and the patient signs the office consent form — but no one mentions that root sensitivity and gingival recession commonly follow. The patient later sues, saying she would have chosen differently had she known. How would California law most likely characterize that claim?

No signup, no email wall — your score, weak-block map, and every rationale appear as soon as you answer the last question.

Practice-test FAQ

Free RDH practice test questions, answered

Is this California RDH Law and Ethics practice test really free?

Yes. The questions, the instant score, the weak-block map, and every answer rationale are free. There is no signup to start and no email required to see your results.

Are these real questions from the RDH Laws and Ethics Written Examination?

No. Dentovio uses original exam-style questions written against the DHBC's published 2025 examination outline. It does not reproduce official, live, recalled, or confidential DHBC or PSI exam items.

What does the practice test cover?

15 questions distributed across the seven blocks of the DHBC's official 2025 outline (1A Informed Consent through 3B Obligations within the Professional Role), so every block of the official outline is sampled. Treat a 15-question score as directional.

Is this for the RDH exam or the dentist / RDA exam?

This practice test targets the Registered Dental Hygienist (RDH) Laws and Ethics Written Examination run by the Dental Hygiene Board of California. The dentist Law and Ethics exam (Dental Board of California) and the RDA Combined Written Exam are separate exams with different outlines and different scoring rules.

What happens after I finish the practice test?

You see your score, a block-by-block breakdown against the official 2025 outline, every question's rationale, and a retest of the questions you missed. Finishing also unlocks the $89 diagnostic-completion price for the full prep instead of the regular $99 price.
