Introduction
The Florida Dental Assistant Infection Control Examination evaluates a candidate's
ability to apply evidence-based infection prevention principles in everyday clinical
practice. The examination emphasizes patient safety, occupational health, sterilization
procedures, environmental asepsis, exposure prevention, documentation, regulatory
compliance, and professional judgment. Candidates are expected to interpret realistic
clinical situations, identify appropriate corrective actions, and demonstrate
knowledge consistent with current CDC recommendations, OSHA Bloodborne
Pathogens requirements, and accepted infection control standards applicable to
dental settings. Success requires more than memorization—it demands critical
thinking, risk assessment, and consistent application of infection control protocols to
protect patients, dental personnel, and the public.
Question 1
,A dental assistant discovers that the biological monitoring test for a steam sterilizer
indicates sterilization failure. Several instrument packs processed since the last
negative spore test have already been used. What is the MOST appropriate
immediate action?
A. Continue using the sterilizer while repeating the biological test.
B. Remove the sterilizer from service, investigate the cause, and evaluate patient
notification based on risk assessment.
C. Increase sterilization time for future loads without documenting the incident.
D. Use only chemical indicators until the next scheduled spore test.
Correct Answer: B
Explanation: A failed biological indicator requires immediate removal of the
sterilizer from service, investigation, corrective action, and evaluation of potentially
affected patients according to established protocols.
Question 2
A patient reports active pulmonary tuberculosis and requires urgent dental
treatment. Which approach BEST minimizes transmission risk?
A. Schedule the patient during regular office hours.
B. Perform treatment using only a surgical mask.
C. Defer elective treatment and refer urgent care to an appropriately equipped
facility using airborne infection precautions.
D. Increase room ventilation by opening windows.
Correct Answer: C
Explanation: Active tuberculosis requires airborne infection precautions that are
generally unavailable in routine dental offices.
,Question 3
While removing contaminated gloves, a dental assistant accidentally touches the
outer glove surface with bare fingers. What should occur NEXT?
A. Continue working carefully.
B. Apply alcohol sanitizer over the contamination.
C. Remove gloves completely, perform hand hygiene, and don new gloves before
patient care.
D. Wipe hands with disinfectant.
Correct Answer: C
Explanation: Any glove removal contamination requires immediate hand hygiene
before donning fresh gloves.
Question 4
Which sterilization monitoring method provides the MOST direct evidence that
microorganisms have been destroyed?
A. Mechanical monitoring
B. Chemical indicator strips
C. Biological indicator testing
D. Instrument color change
Correct Answer: C
Explanation: Biological indicators verify microbial destruction and are considered
the gold standard for sterilization monitoring.
Question 5
, Following treatment, visible blood remains on an instrument before sterilization.
What is the greatest concern?
A. Sterilization temperature will increase.
B. Organic debris may interfere with sterilization effectiveness.
C. Instrument corrosion will immediately occur.
D. Packaging integrity improves.
Correct Answer: B
Explanation: Organic material can shield microorganisms and reduce sterilization
effectiveness.
Question 6
Which statement BEST reflects Standard Precautions?
A. They apply only to patients known to have infectious diseases.
B. They apply to all patients regardless of diagnosis.
C. They are optional during routine examinations.
D. They replace instrument sterilization.
Correct Answer: B
Explanation: Standard Precautions assume that every patient may harbor
transmissible pathogens.
Question 7
During ultrasonic instrument cleaning, the assistant notices heavy splashing from the
tank. What is the BEST corrective measure?
A. Remove the lid permanently.
B. Reduce solution level and operate with the lid closed according to manufacturer
