20 Occupational Safety & Records Practice Questions & Answers

1. 1. Under the OSHA Bloodborne Pathogens Standard (29 CFR 1910.1030), how is saliva generated during a dental procedure classified?

   • A.It is other potentially infectious material only when the saliva is visibly streaked with blood.
   • B.It is other potentially infectious material only during surgical procedures such as extractions.
   • C.It is other potentially infectious material in any dental procedure, whether or not blood is visible.✓ Answer
   • D.It falls outside the standard, because saliva is not one of the body fluids the rule lists.

   The definitions paragraph of the standard names saliva in dental procedures in its list of other potentially infectious materials, so no judgement about visible blood is needed: every dental procedure is treated as involving such material, which is why the standard applies to routine restorative and hygiene care.

2. 2. The OSHA Bloodborne Pathogens Standard (29 CFR 1910.1030) requires both engineering controls and work practice controls. Which pairing matches each item to the correct category?

   • A.The puncture-resistant sharps container is a work practice control and the one-handed scoop technique is a true engineering control.
   • B.The puncture-resistant sharps container is an engineering control and the one-handed scoop technique is a work practice control.✓ Answer
   • C.Both the sharps container and the one-handed scoop technique are engineering controls, because each one relies on equipment.
   • D.Both the sharps container and the one-handed scoop technique are work practice controls, because staff perform each of them.

   An engineering control isolates or removes the hazard from the workplace through a device, while a work practice control reduces the chance of exposure by changing the way the task is carried out; the container is a physical device, the scoop technique is a manner of working. The standard requires both, and personal protective equipment covers only the exposure that remains after them.

3. 3. Under the OSHA Bloodborne Pathogens Standard (29 CFR 1910.1030), how must a container for contaminated sharps be handled while it is in use in the operatory?

   • A.It is kept sealed between uses, carried to the chairside only when a sharp is discarded, and pressed down when full.
   • B.It is kept in a cabinet under the counter, opened only by the instrument processing staff, and closed once contents settle.
   • C.It is kept upright, stored in the sterilization area away from patients, and emptied into a red bag weekly.
   • D.It is kept upright, placed as close as is feasible to the point of use, and replaced before it overfills.✓ Answer

   The standard requires sharps containers to be easily accessible and as close as feasible to the immediate area where sharps are used, maintained upright throughout use, and replaced routinely so they are never allowed to overfill; an overfilled or distant container is what drives the reaching, transporting and compacting that cause injuries.

4. 4. A dental office is completing the annual review of its written exposure control plan. Under the OSHA Bloodborne Pathogens Standard (29 CFR 1910.1030), which two items must that annual review document?

   • A.Consideration and implementation of safer medical devices, and solicitation of input from non-managerial employees who give direct patient care.✓ Answer
   • B.Approval of the plan by the practice's liability insurance carrier, and solicitation of input from non-managerial employees who give direct care.
   • C.Consideration and implementation of safer medical devices, and the hepatitis B antibody titer result of every employee who has occupational exposure.
   • D.Approval of the plan by an outside consultant, and the result of every biological indicator that the office ran during the past calendar year.

   The plan must be reviewed and updated at least annually, and that review carries two documentation duties candidates routinely forget: it must reflect changes in technology by documenting consideration and implementation of appropriate commercially available safer medical devices, and the employer must document that it solicited input on selecting those devices from non-managerial employees responsible for direct patient care.

5. 5. After an employee's exposure incident, the evaluating health care professional sends the employer a written opinion. Under the OSHA Bloodborne Pathogens Standard (29 CFR 1910.1030), what does that opinion contain and when must the employee receive a copy?

   • A.It states that the employee was told the results and warned of any condition needing further care, and reaches the employee within 15 days of the evaluation.✓ Answer
   • B.It states the employee's own diagnosis and every laboratory result obtained in the evaluation, and reaches the employee within 15 days.
   • C.It states the source patient's test results and infection status alongside the employee's findings, and reaches the employee within 15 days.
   • D.It states that the employee was told the results and warned of any condition needing further care, and reaches the employee within 30 days.

   The employer must obtain and provide the written opinion to the employee within 15 days of the completed evaluation, and the standard deliberately limits its content to the statement that the employee was informed of the results and told of any condition resulting from the exposure that needs further evaluation or treatment; all other findings and diagnoses stay confidential and must not appear in it.

6. 6. After a needlestick, an employee agrees to have a baseline blood sample drawn but does not want an HIV test run on it at this time. Under the OSHA Bloodborne Pathogens Standard (29 CFR 1910.1030), what happens to that sample?

   • A.It is tested for HIV in any case, because consent to the blood draw counts as consent to the testing.
   • B.It is preserved for at least 90 days, so the employee may still ask that the HIV test be run on it.✓ Answer
   • C.It is discarded right away, and a fresh sample must be drawn if the employee later asks for HIV testing.
   • D.It is sent to the source patient's physician, who then decides whether the HIV test should be performed.

   The standard protects the employee's right to decide about HIV testing while still preserving the evidence a later claim would need: if the employee consents to baseline collection but declines HIV serologic testing, the sample must be preserved for at least 90 days, and if the employee changes her mind within that period the testing is done as soon as feasible.

7. 7. A dental assistant with occupational exposure tells her employer that she does not want the hepatitis B vaccine at this time. Under the OSHA Bloodborne Pathogens Standard (29 CFR 1910.1030), what must happen next?

   • A.She signs the required declination statement, which permanently gives up her right to the free vaccine.
   • B.She must sign a declination witnessed by the dentist and repeat it at each annual training session.
   • C.She must first undergo antibody prescreening, and the employer may bill her if she still declines it.
   • D.She signs the required declination statement and may still request the free vaccine later while covered.✓ Answer

   An employee who declines must sign the declination statement set out in the appendix to the standard, but declining is never final: an employee who continues to have occupational exposure may accept the vaccination at any later time, still at no cost, and the employer may not make participation in a prescreening program a condition of receiving the vaccine.

8. 8. The exposure determination in a written exposure control plan lists the job classifications and tasks that carry occupational exposure. Under the OSHA Bloodborne Pathogens Standard (29 CFR 1910.1030), on what basis is that determination made?

   • A.On the basis of the exposure incidents the office actually recorded during the previous calendar year.
   • B.On the assumption that no protective equipment is worn, so gloves and masks do not exempt a job.✓ Answer
   • C.On the basis of each employee's hepatitis B vaccination status, so vaccinated staff are left off the list.
   • D.On the basis of the protective equipment worn, so a gowned and gloved employee is left off the list.

   The determination asks who could reasonably be expected to contact blood or other potentially infectious materials if no protective equipment were used at all, so it is made without regard to gloves, masks, gowns or eyewear; treating protective equipment as a reason to leave a classification off the list would remove the very people the plan exists to protect.

9. 9. Under the OSHA Bloodborne Pathogens Standard (29 CFR 1910.1030), which set of items must appear in the record of a bloodborne pathogens training session?

   • A.The dates of the sessions, the sterilizer logs reviewed during them, and a copy of the exposure control plan handed out.
   • B.The dates, a summary of the contents, the trainer's name and qualifications, and the attendees' names and job titles.✓ Answer
   • C.The dates, a summary of the contents, the score each attendee earned on the post-test, and the signature of each attendee.
   • D.The dates of the sessions, the attendees' names and personal identification numbers, and each attendee's vaccination status.

   The standard lists exactly four items for a training record, and naming the trainer's qualifications is the one most often left out; the record has to show not only that a session happened but that the person who ran it was knowledgeable in the subject matter as it applies to this workplace.

10. 10. An employer is deciding how long to keep two records required by the OSHA Bloodborne Pathogens Standard (29 CFR 1910.1030): an employee's medical record and the bloodborne pathogens training record. Which retention pairing is correct?

    • A.The medical record for the duration of employment plus 30 years; the training record for 3 years.✓ Answer
    • B.The medical record for the duration of employment plus 5 years; the training record for 30 years.
    • C.The medical record for 30 days after the employee resigns; the training record for 5 years after the session.
    • D.The medical record for 3 years after the exposure incident; the training record for the whole of employment.

    Employee medical records follow the long retention rule for exposure and medical records, the duration of employment plus 30 years, because a bloodborne disease can surface decades after the exposure, while training records need only cover the enforcement window and are kept 3 years from the date of the session. Medical records are also confidential and released only with the employee's written consent.

11. 11. Under the OSHA Bloodborne Pathogens Standard (29 CFR 1910.1030), what information must an entry on the sharps injury log contain?

    • A.The date of the last training session, the employee's vaccination status, and the source patient's test results.
    • B.The name of the injured employee, the name of the source patient, and the treatment the employee received.
    • C.The type and brand of device involved, the work area where it happened, and how the incident occurred.✓ Answer
    • D.The type and brand of device involved, the injured employee's name and job title, and the dentist's signature.

    The log exists to show which devices and which areas are producing percutaneous injuries so that safer devices can be chosen, which is why it captures the device type and brand, the department or work area, and an explanation of how the injury happened. It must also be recorded in a way that protects the injured employee's confidentiality, so identifying details are kept out of it.

12. 12. A practice plans to meet its annual bloodborne pathogens training requirement by emailing staff a recorded video to watch on their own time at home. Under the OSHA Bloodborne Pathogens Standard (29 CFR 1910.1030), why is this not acceptable?

    • A.Training must be held in a classroom away from the office, with attendance certified by an auditor.
    • B.Training must be completed before the date of hire, so an employee already working may no longer receive it.
    • C.Training must be held during working hours and give employees a chance to ask a knowledgeable person questions.✓ Answer
    • D.Training must be delivered by a licensed physician or registered nurse and repeated twice a year.

    The standard requires training at no cost to the employee and during working hours, delivered by a person knowledgeable in the subject matter, and it requires an opportunity for interactive questions and answers with that person; a video watched alone at home provides no way to ask questions and does not meet the requirement on its own.

13. 13. A dental assistant splashes a chemical disinfectant into her eye. Under the OSHA Hazard Communication Standard (29 CFR 1910.1200), which section of that product's safety data sheet gives the immediate first-aid measures?

    • A.Section 11, which reports toxicological data such as routes of exposure and effects.
    • B.Section 8, which sets out exposure controls and personal protection for the product.
    • C.Section 4, the first-aid measures section of the standardized 16-section format.✓ Answer
    • D.Section 2, which gives hazard identification, the signal word and hazard statements.

    Every safety data sheet follows the same 16-section order, which is what makes the format useful in an emergency: Section 4 always holds the first-aid measures, so a splash sends you to Section 4 rather than to the hazard or toxicology sections, while Section 8 is consulted beforehand to decide what protection to wear.

14. 14. Under the OSHA Hazard Communication Standard (29 CFR 1910.1200), how must safety data sheets be kept for the hazardous chemicals used in a dental office?

    • A.Available from the manufacturer by telephone, so the office keeps no copies of its own on hand.
    • B.Readily accessible to employees in their work area during each work shift, on paper or electronically.✓ Answer
    • C.Filed with the local fire department, which keeps the office's official copies of the sheets it uses.
    • D.Readily accessible in a locked office, from which the owner retrieves a sheet on a written request.

    The employer must maintain safety data sheets in the workplace and ensure they are readily accessible to employees in their work areas during each work shift, because the information is useless if it cannot be reached at the moment of a splash or spill; electronic access is permitted only when nothing stands between the employee and immediate access to the sheet.

15. 15. A bottle of hazardous chemical stored in a dental office work area is not the original shipped container. Under the OSHA Hazard Communication Standard (29 CFR 1910.1200), what is the minimum information the workplace label on that bottle must carry?

    • A.The product identifier, plus the date of transfer and the initials of the employee who filled the bottle.
    • B.The full shipped-container label, since that is the only labeling the standard accepts in a workplace.
    • C.The product identifier, plus the manufacturer's address and the emergency telephone number for the product.
    • D.The product identifier, plus words, pictures or symbols conveying general information on the hazards.✓ Answer

    For containers used inside the workplace the employer may either reproduce the full shipped label or use the shorter workplace option, which is the product identifier together with words, pictures, symbols or a combination that convey general information about the hazards; the label must be legible, in English, and displayed prominently on the container.

16. 16. A practice manual cites both CDC infection prevention recommendations and the OSHA Bloodborne Pathogens Standard. What is the difference in the legal force of the two documents?

    • A.Both are voluntary, so an employer may adopt whichever parts of either document suit the practice's routine.
    • B.Both are federal regulations, so an employer may be cited and fined for departing from either of the documents.
    • C.CDC issues regulations enforced by inspection, while OSHA publishes voluntary guidance for health care employers.
    • D.CDC issues recommendations, while OSHA issues regulations an inspector can cite and fine an employer under.✓ Answer

    CDC is a public health agency that publishes evidence-based recommendations, while OSHA is a regulatory agency whose standards are codified in the Code of Federal Regulations and enforced through inspection, citation and penalty. Practices adopt CDC guidance into their own written policies, and a state may also write that guidance into rule, which is how a recommendation becomes locally enforceable.

17. 17. A dental office uses a surface disinfectant on countertops and a liquid chemical sterilant to process a heat-sensitive semicritical device. Which federal agency has authority over each product?

    • A.EPA registers the surface disinfectant, and FDA clears the liquid chemical sterilant used on devices.✓ Answer
    • B.OSHA registers both products, because employees are exposed to the chemicals while using them at work.
    • C.CDC registers both products, because its infection prevention guidelines describe how each one is to be used.
    • D.FDA registers the surface disinfectant, and EPA clears the liquid chemical sterilant used on devices.

    The two agencies split the work by where the product is used: EPA registers antimicrobial pesticides, which includes the hospital disinfectants applied to clinical contact and housekeeping surfaces, while FDA regulates medical devices and clears the liquid chemical sterilants and high-level disinfectants used to process patient-care instruments. A surface product is therefore never used to immersion-process instruments.

18. 18. Staff discover that a cassette of instruments used on a patient that morning had never gone through the sterilizer. What is the appropriate response to this infection control breach?

    • A.Note the event in that patient's chart alone, and carry on as usual because no employee was exposed to blood here.
    • B.Reprocess the instruments now, and record the correction in the sterilization log without identifying the patient involved.
    • C.Report the event to the instrument manufacturer, whose findings then decide whether the patient has to be told anything.
    • D.Take the items out of use, document the patients and the root cause, and consult the health authority on notification.✓ Answer

    A breach is a lapse in infection prevention that may have exposed patients, so the response is to stop the practice at once, remove the implicated items from service, investigate and document what happened and why, consult the health authority about whether patients should be notified and offered testing, and then correct the process, retrain and record the corrective action.

19. 19. A practice wants its sterilization records to let it identify exactly which packages are affected if a load later turns out to be suspect. Which record-keeping practice makes that possible?

    • A.Record the sterilizer, the date, the load number and the contents, and mark each package with that load information.✓ Answer
    • B.Record the operator's initials on each package, because that operator can recall which instruments went into each load.
    • C.Record only the date of each cycle, because the packages are stored by date and can be sorted off the shelf later.
    • D.Record the weekly spore test result alone, because one passing biological indicator accounts for every load that week.

    Monitoring records are only useful if they link a specific package to a specific cycle, so the log records the sterilizer, the date and load or cycle number, the contents, the cycle parameters and the operator, and each package carries the same identifying information. When a load is later found suspect, that link is what allows every affected package to be pulled and reprocessed instead of guessing.

20. 20. A practice wants evidence that its infection prevention program is actually being followed and not merely written down. Which activity does the CDC infection prevention framework describe for that purpose?

    • A.Replacement of the written policies with the manufacturer's instructions for every product in use.
    • B.Collection of patient satisfaction surveys, which show whether infection prevention procedures are being followed.
    • C.Documented observation of staff adherence to the written policies, followed by corrective action and re-evaluation.✓ Answer
    • D.Annual submission of the written policies to OSHA for review and approval before the practice may put them to use.

    The framework expects a designated, trained infection prevention coordinator to run a routine evaluation of the program that includes direct observation of personnel adherence to policies such as hand hygiene, protective equipment and instrument processing, using a checklist; a deficiency is traced to its cause, corrected, retrained on and then re-audited to confirm the improvement held.
