The Assistant Who Reported the Office

Correct answer: D. OSHA

• A. The CDC issues RECOMMENDATIONS and guidelines — including the infection control guidelines for dental settings — but it has no enforcement authority and does not receive employee safety complaints.
• B. The FDA regulates devices, drugs and materials, including the clearance of sterilants and disinfectants. It does not regulate workplace practices.
• C. The state dental board licenses and disciplines dentists on matters of professional conduct and patient care. It is not the route for an employee's occupational safety complaint, though serious deficiencies may also warrant its attention.
• D. CORRECT. OSHA — the Occupational Safety and Health Administration — is the REGULATORY and ENFORCEMENT body for workplace safety. It is the agency that issues the Bloodborne Pathogens Standard and the Hazard Communication Standard, and it is the agency an employee files a complaint with when workplace practices place them at risk. OSHA can inspect and can fine.

Note: The clean division to memorise: CDC RECOMMENDS, OSHA ENFORCES (for employee safety), FDA CLEARS products, EPA registers surface disinfectants, and the state board licenses.

Correct answer: D. The employer must OFFER the vaccine free of charge to at-risk employees within 10 working days of assignment

• A. The obligation is a legal requirement, not a recommendation.
• B. Charging the employee is a direct violation. The employer bears the cost, including the post-vaccination antibody titre.
• C. The employee cannot be compelled to be vaccinated. An employee who declines must sign the specific OSHA declination form, and may request and receive the vaccine later at any time at no cost.
• D. CORRECT. Under the Bloodborne Pathogens Standard, the employer MUST make the hepatitis B vaccine series available at NO COST, at a reasonable time and place, within 10 working days of initial assignment to a job with occupational exposure. Offering it is mandatory for the employer; ACCEPTING it is voluntary for the employee.

Note: The same standard requires an exposure control plan reviewed ANNUALLY, engineering controls including safer sharps devices, employee training on hire and annually thereafter, and post-exposure evaluation and follow-up at no cost.

Correct answer: A. HIV

• A. CORRECT. Routine HIV screening of dental employees is NOT required. Testing is voluntary and confidential, and is offered as part of post-exposure evaluation after a specific incident — never as routine surveillance. There is no HIV vaccine and no routine titre to check.
• B. Post-vaccination anti-HBs titre testing IS part of the standard, performed 1–2 months after the final dose to confirm seroconversion. Non-responders are offered a second series.
• C. Hepatitis C testing IS part of the post-exposure evaluation protocol following a specific incident.
• D. TB screening at hire and periodically thereafter is required, with the frequency determined by the facility's community risk assessment.

Note: The underlying principle is that routine testing without an exposure incident stigmatises workers without protecting them. Standard precautions — treating EVERY patient as potentially infectious — is what actually provides protection.

Correct answer: A. Gown, mask, eye protection, gloves

• A. CORRECT. The CDC donning sequence is GOWN → MASK or respirator → GOGGLES or face shield → GLOVES. Gloves go on LAST so that they can be pulled over the gown cuffs, sealing the wrist. The logic runs from the body outward, ending with the hands.
• B. This sequence has gloves second, which creates the same problem.
• C. Gloves first defeats the purpose entirely — you cannot then put on a gown and mask without contaminating the gloves.
• D. This reverses the sequence and ends with the gown, leaving the cuffs unsealed.

Note: ⚑ The recall recorded 'gowns, eye wear, mask, gloves'. The order of the mask and eye protection is a minor variant between sources, but GOWN FIRST and GLOVES LAST is fixed and is what is actually tested. DOFFING is nearly the reverse and matters more for safety: gloves → goggles → gown → mask, removing the most contaminated item first and performing hand hygiene throughout.

Correct answer: C. A refrigerator storing dental materials and impression supplies

• A. Sharps containers DO require the biohazard label, and must additionally be closable, puncture-resistant, leak-proof and located as close as practical to the point of use.
• B. This DOES require labelling. Contaminated laundry must be bagged and labelled, particularly when it leaves the facility, so that handlers downstream are warned.
• C. CORRECT — this is the EXCEPTION. A refrigerator holding only DENTAL MATERIALS contains no potentially infectious material, so no biohazard labelling is required. Labelling everything indiscriminately is counterproductive: it dilutes the warning and staff stop attending to it.
• D. This DOES require labelling. Refrigerators or freezers containing blood, other potentially infectious material or patient specimens must carry the biohazard symbol.

Note: The label itself is specified: fluorescent orange or orange-red, with the biohazard symbol and the word BIOHAZARD in a contrasting colour.
