Registered Dental Hygienist in Alternative Practice (RDHAP) Law and Ethics Practice Exam

What must a dental hygienist in alternative practice obtain if they provide services to a patient after 18 months from the initial service?

1. Written verification from a dentist

2. Verbal confirmation from a physician

3. A new prescription from the patient

4. Referral from a dental assistant

The correct answer is: Written verification from a dentist

A dental hygienist in alternative practice is required to maintain a collaborative practice with a supervising dentist. When providing services to a patient after 18 months from the initial service, it is essential to obtain written verification from a dentist. This requirement ensures that the hygienist is operating within the guidelines of dental regulations and that any treatment or care is supported by a professional's oversight. The need for written verification indicates an ongoing evaluation of the patient's oral health status and the appropriateness of further treatment, which is a critical component of the ethical and legal practice in dentistry. The other options do not fulfill the legal requirements set forth for dental hygienists in alternative practice. Verbal confirmation from a physician, a new prescription from the patient, or a referral from a dental assistant do not establish the necessary formalized relationship with a dentist, which is crucial for patient safety and quality of care. Thus, obtaining written verification remains a vital aspect of continuing care beyond the 18-month threshold.
