1. A registered dental hygienist practicing in a community clinic in
Ontario is asked by a supervising dentist to perform a procedure
involving administration of local anesthesia despite not holding the
provincial authorization or certification required to independently
perform the controlled act. The dentist assures the hygienist that the
clinic is short-staffed and that the responsibility will rest with the
dentist. Which of the following is the most appropriate action by the
dental hygienist under Canadian professional jurisprudence principles?
A. Proceed because delegation from a dentist automatically removes all
liability from the hygienist
,B. Refuse to perform the procedure until legally authorized and
appropriately competent to do so
C. Perform the procedure if another hygienist is present in the operatory
D. Proceed because patient access to care overrides provincial scope
limitations
B. Refuse to perform the procedure until legally authorized and
appropriately competent to do so
Rationale: Canadian dental hygiene jurisprudence requires registrants to
practice within authorized scope, competence, and applicable delegation
rules. A supervising dentist cannot eliminate the hygienist’s professional
accountability. Performing unauthorized controlled acts may constitute
professional misconduct and place patient safety at risk.
2. A dental hygienist receives a subpoena requesting copies of a patient’s
clinical records for use in a civil lawsuit involving alleged injury after
periodontal treatment. The patient has not provided consent for
disclosure. Which response best aligns with Canadian privacy and legal
obligations?
A. Refuse disclosure because patient consent is always required
B. Destroy any personal notes before responding to the subpoena
C. Provide the records in accordance with the subpoena and applicable
,legislation
D. Release only billing information because clinical records are confidential
C. Provide the records in accordance with the subpoena and applicable
legislation
Rationale: Court orders and subpoenas may legally compel disclosure of
records without patient consent. Dental hygienists must comply with
lawful legal processes while ensuring disclosure is limited to what is
required and handled according to professional and privacy legislation.
3. During an appointment, a patient reveals that they occasionally take
antibiotics obtained from family members without medical advice. The
patient requests that this information not be documented because
they fear criticism from their physician. What is the dental hygienist’s
best course of action?
A. Exclude the information because the patient requested confidentiality
B. Document the disclosure accurately because it may affect clinical care
C. Record the information only if a physician specifically requests it
D. Omit the information because it is unrelated to oral hygiene
B. Document the disclosure accurately because it may affect clinical care
Rationale: Accurate, complete, and contemporaneous recordkeeping is a
legal and professional obligation. Medication misuse may influence
, treatment planning, infection risk, and medical management. Omitting
clinically relevant information compromises patient safety and
professional accountability.
4. A dental hygienist in British Columbia posts before-and-after patient
photographs on a professional social media page after obtaining
verbal consent during the appointment. Several months later, the
patient complains they never understood the images would be
publicly accessible online. Which principle is most relevant to this
complaint?
A. Implied consent is sufficient for all educational purposes
B. Consent for public disclosure must be informed, explicit, and
appropriately documented
C. Verbal consent is legally superior to written consent
D. Educational promotion is exempt from privacy legislation
B. Consent for public disclosure must be informed, explicit, and
appropriately documented
Rationale: Public disclosure of patient information or images requires clear
informed consent that explains risks, audience, duration, and purpose.
Written documentation is strongly recommended to demonstrate the
patient understood the implications of online publication.
