1. A Florida dentist asks a dental assistant to take an impression
that will be used solely to fabricate a study cast. Which statement
best describes this task?
A. It is always an irremediable task that may never be delegated.
B. It is a remediable task that may be delegated when the applicable
training and supervision requirements are satisfied.
C. It may only be performed by a licensed dental hygienist.
D. It may only be performed by a dental laboratory technician.
Answer: B. It is a remediable task that may be delegated when the
applicable training and supervision requirements are satisfied.
Rationale: Florida law specifically identifies taking impressions for
study casts as a remediable and delegable task. The distinction is
important: the statutory authorization is for study casts, not for
impressions intended to fabricate intraoral restorations or orthodontic
appliances. The assistant must also satisfy applicable Board training
and supervision requirements.
2. Which procedure is specifically identified by Florida statute as a
remediable and delegable task?
1
,A. Diagnosis of dental caries
B. Treatment planning
C. Removal of sutures
D. Prescription of antibiotics
Answer: C. Removal of sutures
Rationale: Florida Statutes §466.024 expressly lists removing sutures
among remediable tasks that may be delegated. Diagnosis, treatment
planning, and prescribing drugs requiring a prescription remain
outside the dental assistant's delegated authority.
3. A dental assistant is asked to diagnose whether a patient has
irreversible pulpitis before the dentist enters the operatory. What is
the appropriate response?
A. Perform the diagnosis if the assistant has completed an expanded-
functions course.
B. Perform the diagnosis only under indirect supervision.
C. Perform the diagnosis only if the patient has previously been treated
in the office.
D. Do not perform the diagnosis because diagnosis may not be delegated
to a dental assistant.
Answer: D. Do not perform the diagnosis because diagnosis may not
be delegated to a dental assistant.
Rationale: Expanded-functions training does not convert a dental
assistant into a licensed dentist. Florida law specifically prohibits
delegation of diagnosis for treatment or treatment planning to anyone
other than another licensed dentist.
4. Which statement most accurately describes the dentist's
responsibility for delegated procedures?
2
,A. The assistant assumes all legal responsibility after accepting the task.
B. The dental laboratory assumes responsibility.
C. The dentist remains primarily responsible for procedures delegated by
the dentist.
D. Responsibility automatically transfers to the supervising dental
hygienist.
Answer: C. The dentist remains primarily responsible for
procedures delegated by the dentist.
Rationale: Florida Statutes §466.024 states that the dentist is primarily
responsible for procedures delegated by the dentist. Delegation
therefore does not eliminate the dentist's professional responsibility.
5. A dental assistant has never received the training required for an
intraoral procedure but tells the dentist that she has observed the
procedure many times. What is the most appropriate conclusion?
A. Observation alone automatically qualifies her.
B. She may perform it because the dentist is present.
C. She may perform it only after receiving the training prescribed by
Board rule.
D. She may perform it if the patient signs a waiver.
Answer: C. She may perform it only after receiving the training
prescribed by Board rule.
Rationale: Florida law provides that a dental assistant may not
perform an intraoral procedure until receiving the formal or on-the-
job training prescribed by the Board. Merely observing the procedure
is not automatically equivalent to qualifying training.
6. Which of the following is NOT a task that Florida law permits a
dentist to delegate to a dental assistant?
3
, A. Placing a rubber dam
B. Removing a temporary restoration
C. Applying a cavity liner
D. Diagnosing periodontal disease
Answer: D. Diagnosing periodontal disease
Rationale: Placing or removing rubber dams, removing temporary
restorations, and applying cavity liners are identified as remediable
tasks. Diagnosis is not a delegable dental-assistant function.
7. A dentist asks an expanded-functions dental assistant to polish an
amalgam restoration. What is the primary legal consideration?
A. Whether the assistant has the appropriate training and the task is
performed under the required supervision.
B. Whether the assistant has a dental hygiene license.
C. Whether the patient is over age 18.
D. Whether the procedure is performed in a hospital.
Answer: A. Whether the assistant has the appropriate training and
the task is performed under the required supervision.
Rationale: Polishing amalgam restorations is specifically identified as
a remediable task. The assistant must nevertheless comply with
applicable Board training and supervision requirements.
8. Which action is specifically prohibited from being delegated by a
dentist to a dental assistant?
A. Placing a matrix
B. Removing a periodontal dressing
C. Prescribing a medication requiring a prescription
D. Taking a study-cast impression
