1. Question 1 of 25Medium

   To minimize musculoskeletal fatigue during extended periods of standing at packaging workstations, which combination of environmental controls is recommended?

   1. AA. Fixed-height high tables requiring continuous upward arm reach
   2. BB. Hard concrete flooring and firm, non-cushioned safety shoes
   3. CC. Anti-fatigue floor mats and an elevated footrest to shift weight
   4. DD. Continuous use of a rigid lumbar support brace while standing
   Show answer to question 1

   Answer: C. Anti-fatigue floor mats and an elevated footrest to shift weight

   Anti-fatigue mats cushion joint impacts and stimulate subtle muscular contractions that promote venous return, while an elevated footrest allows staff to alternate foot placement and reduce static load on the lower back. Continuous rigid back bracing is not recommended for workstation ergonomics as it can weaken stabilizing core muscles over time.

2. Question 2 of 25Medium

   Condensation drips from an overhead chilled water line onto several wrapped instrument trays resting on the top wire shelf in sterile storage. What is the required corrective action for the wet trays?

   1. AA. Wipe the external wrap dry and allow the sets to aerate on the shelf
   2. BB. Replace only the outer wrap and run a flash steam cycle
   3. CC. Run the sets through an aeration cycle in an ethylene oxide chamber
   4. DD. Send the sets back to decontamination for complete reprocessing
   Show answer to question 2

   Answer: D. Send the sets back to decontamination for complete reprocessing

   External moisture compromises the sterile barrier via wicking and allows potential microbial transfer into the pack, so the items must be treated as contaminated and sent back to decontamination for full cleaning and reprocessing. Drying or wiping the outer wrap does not restore sterility once moisture contact has occurred.

3. Question 3 of 25Easy

   According to standard infection prevention guidelines, how frequently should floors in Central Service work areas be wet mopped or vacuumed?

   1. AA. At least daily or at the end of each shift
   2. BB. Only when visible spills or gross contamination occur
   3. CC. Once every month during terminal cleaning
   4. DD. Once every week during scheduled downtime
   Show answer to question 3

   Answer: A. At least daily or at the end of each shift

   Floors in both decontamination and clean processing areas must be cleaned at least daily or at the conclusion of each work shift using a dedicated wet-vacuum or clean wet mop. Delaying floor care to a weekly or monthly schedule allows soil, lint, and microbial contamination to accumulate and be dispersed by departmental foot traffic.

4. Question 4 of 25Hard

   An environmental services worker will clean three SPD areas during the night shift: decontamination, preparation and packaging, and sterile storage. Which plan is correct?

   1. AA. Decontamination first and clean areas after, using the same mop in each area with fresh water
   2. BB. Sterile storage first and decontamination last, with separate tools kept for decontamination
   3. CC. Sterile storage first and decontamination last, using the same mop in each area with fresh water
   4. DD. Decontamination first and clean areas after, with separate tools kept for decontamination
   Show answer to question 4

   Answer: B. Sterile storage first and decontamination last, with separate tools kept for decontamination

   Cleaning moves from the cleanest area to the dirtiest so that soil is not carried into clean spaces, which puts sterile storage first and decontamination last. Tools used in decontamination stay there and are not used in clean areas.

   Why the other options are wrong

   • AStarting in decontamination and using the same mop everywhere carries contamination into the clean areas.
   • CThe order is right, but a mop also used in decontamination carries its soil back to the clean areas the next time it is used.
   • DSeparate tools help, but cleaning the dirtiest area first and then entering clean areas can track soil into them.

5. Question 5 of 25Hard

   A sterile processing department observes a decline in case cart fill rates and a simultaneous rise in IUSS rates. Investigation reveals instrument sets are chronically delayed in decontamination. What is the most likely process breakdown contributing to this turnaround bottleneck?

   1. AA. Instrument storage areas were maintained at 68 degrees Fahrenheit and 40 percent relative humidity
   2. BB. Chemical indicators inside peel-pouches were placed diagonally rather than parallel to seals
   3. CC. Point-of-use pre-cleaning was omitted in the operating room, allowing bioburden to dry
   4. DD. Dynamic-air-removal sterilizers were operated using 4-minute exposure cycles at 270 degrees Fahrenheit
   Show answer to question 5

   Answer: C. Point-of-use pre-cleaning was omitted in the operating room, allowing bioburden to dry

   Failing to apply point-of-use pre-treatment in the surgical suite allows blood and tissue to dry, dramatically increasing the time, effort, and re-washing required in decontamination. This delay chokes turnaround times, causing delayed or missing sets on case carts and prompting OR teams to resort to IUSS. Indicator orientation, standard sterilization parameters, and appropriate storage climate do not delay the decontamination throughput.

6. Question 6 of 25Easy

   A newly hired technician finishes the department's orientation checklist with her preceptor. What should happen to the completed checklist?

   1. AA. It is thrown away once she starts working on her own
   2. BB. It is kept by the technician as her personal reference
   3. CC. It is signed by both of them and kept in her training file
   4. DD. It is posted in the break room so others can see her skills
   Show answer to question 6

   Answer: C. It is signed by both of them and kept in her training file

   Orientation and training records show that each employee was taught and checked on required tasks. They are signed and kept in the employee's education or personnel file so that managers and surveyors can confirm training.

   Why the other options are wrong

   • ADiscarding the checklist removes proof that orientation was completed.
   • BA personal copy is fine, but the official record stays in the department's training files.
   • DPosting training records in a public area is not proper record keeping and exposes personal information.

7. Question 7 of 25Medium

   According to ANSI/AAMI ST79 recommendations, what is the minimum clearance distance required between the bottom shelf of a sterile storage unit and the floor?

   1. AA. 8 to 10 inches
   2. BB. 12 to 14 inches
   3. CC. 2 to 4 inches
   4. DD. 4 to 6 inches
   Show answer to question 7

   Answer: A. 8 to 10 inches

   ANSI/AAMI ST79 specifies that bottom storage shelves must be at least 8 to 10 inches above the floor to facilitate adequate floor cleaning and protect packages from contamination caused by floor splashing and vacuum exhausts. A clearance of 2 to 4 inches is incorrect because it provides insufficient space for environmental services tools and leaves packages vulnerable to aerosolized mopping water.

8. Question 8 of 25Medium

   A new environmental services worker plans to clean the sterile storage floor with a dry broom. Which method should be used instead?

   1. AA. Dust mopping with a dry, untreated mop to keep moisture away from packages
   2. BB. Damp or wet mopping that holds the dust in place
   3. CC. Vacuuming with a shop vacuum that has no exhaust filter
   4. DD. Running a floor buffer over the floor to lift the dust
   Show answer to question 8

   Answer: B. Damp or wet mopping that holds the dust in place

   Dry sweeping and dusting stir dust, and the microorganisms it carries, into the air, where it can settle on sterile packages. Damp or wet mopping traps the dust instead of spreading it.

   Why the other options are wrong

   • AA dry, untreated mop stirs fine dust into the air, where it settles on packages; a damp mop does not wet packages on the shelves.
   • CA vacuum without exhaust filtration blows fine dust back into the room and onto the packages.
   • DA floor buffer polishes the surface rather than picking up dust, and its spinning pad can throw fine dust into the air.

9. Question 9 of 25Easy

   A team studying wet packs writes the problem at the head of a drawing and groups possible causes on branches labeled people, methods, equipment, materials and environment. Which quality tool is this?

   1. AA. Pareto chart
   2. BB. Fishbone diagram
   3. CC. Run chart
   4. DD. Process flowchart
   Show answer to question 9

   Answer: B. Fishbone diagram

   A fishbone, or Ishikawa, diagram sorts the possible causes of a problem into categories so the team considers every likely source before choosing which ones to test. It is often used during root cause analysis.

   Why the other options are wrong

   • AA Pareto chart ranks categories as bars from most to least frequent.
   • CA run chart plots a measure over time to show trends.
   • DA process flowchart shows the steps of a process in order, not groups of causes.

10. Question 10 of 25Medium

    A technician finds the door between the decontamination area and the SPD corridor propped open with a trash can so that soiled carts can be pushed through faster. What is the main problem with this practice?

    1. AA. Corridor air can recontaminate instruments already cleaned at the sinks
    2. BB. Corridor dust can settle on soiled instruments waiting to be cleaned
    3. CC. Humidity in decontamination can drop too low for enzymatic detergents
    4. DD. Contaminated air from decontamination can escape into the corridor
    Show answer to question 10

    Answer: D. Contaminated air from decontamination can escape into the corridor

    Decontamination is kept at negative pressure, and keeping its doors closed helps hold that pressure difference. A propped-open door weakens the airflow control, so aerosols and vapors from soiled items and cleaning can move out into adjacent areas.

    Why the other options are wrong

    • AAir is meant to flow from the corridor into decontamination; the danger of an open door is contaminated air flowing out.
    • BSoiled instruments will be cleaned anyway, so corridor dust settling on them is not the main concern.
    • CRoom humidity does not control enzymatic detergents, which work according to their dilution, temperature and contact time.

11. Question 11 of 25Hard

    A new technician asks his preceptor why he must follow every step of the department's steam sterilization procedure, which is based on ANSI/AAMI ST79, even on busy days. What is the best answer?

    1. AA. Because the FDA enforces ST79 in hospitals that sterilize medical devices
    2. BB. Because AAMI inspects SP departments and fines those that skip steps
    3. CC. Because OSHA made the ST79 steps part of its worker safety rules
    4. DD. Because the facility adopted the steps, which set the standard of care
    Show answer to question 11

    Answer: D. Because the facility adopted the steps, which set the standard of care

    ST79 is a voluntary consensus standard, but once a facility adopts its steps into its procedures, staff must follow them. Accreditors, surveyors and courts also judge sterile processing practice against recognized standards such as ST79, so its steps reflect the standard of care.

    Why the other options are wrong

    • AThe FDA regulates device manufacturers and does not enforce ST79 in hospital SP departments.
    • BAAMI develops standards but does not inspect SP departments or issue fines.
    • COSHA rules protect workers, and OSHA has not made the ST79 steps part of its regulations.

12. Question 12 of 25Medium

    The posted temperature range for the decontamination area extends lower than the range for the preparation and packaging area. What is the main reason cooler temperatures are allowed in decontamination?

    1. AA. Enzymatic detergents in the sinks break down soil faster in cool room air
    2. BB. Technicians there wear fluid-resistant gowns and other PPE that hold in heat
    3. CC. Instruments waiting to be cleaned dry out faster in cool, moving air
    4. DD. Cool room air helps the sterilizers on the clean side run efficiently
    Show answer to question 12

    Answer: B. Technicians there wear fluid-resistant gowns and other PPE that hold in heat

    Technicians in decontamination wear fluid-resistant gowns, gloves, face protection and other PPE that trap body heat. A cooler range helps prevent heat stress and keeps them comfortable while they work.

    Why the other options are wrong

    • ADetergent performance depends on the solution's dilution and temperature as the label directs, not on cool room air.
    • CSoil should stay moist until cleaning; letting it dry on instruments makes it harder to remove.
    • DDecontamination air is exhausted outdoors and is not used to cool sterilizers on the clean side.

13. Question 13 of 25Hard

    Department policy sets a maximum relative humidity of 60% for sterile storage. At the start of the shift, the sterile storage monitor reads 71%. What should the technician do first?

    1. AA. Report the reading at once to the supervisor and facilities engineering
    2. BB. Move the sterile packages into preparation and packaging, then tell the supervisor
    3. CC. Record the reading and report it at the next monthly safety meeting
    4. DD. Pull the packages from the shelves and send them for reprocessing
    Show answer to question 13

    Answer: A. Report the reading at once to the supervisor and facilities engineering

    An out-of-range reading is reported promptly so that facilities staff can correct the air handling and the supervisor, with infection prevention as policy directs, can decide what happens to the stored items. The reading and the response are also recorded.

    Why the other options are wrong

    • BMoving packages adds handling and puts sterile items in a work area not meant for storage before anyone has assessed the problem.
    • CHolding the report for a monthly meeting delays correction while excess moisture may keep affecting the packages.
    • DWhether stored items need reprocessing is decided by the supervisor and infection prevention, not by the technician alone.

14. Question 14 of 25Easy

    Which SPD work area is kept at negative air pressure compared with the spaces around it?

    1. AA. Sterile storage area
    2. BB. Preparation and packaging area
    3. CC. Decontamination area
    4. DD. Clean case cart holding area
    Show answer to question 14

    Answer: C. Decontamination area

    The decontamination area receives soiled, contaminated items, so it is kept at negative pressure. Air flows into it from surrounding spaces and is exhausted, which keeps contaminated aerosols from drifting into clean areas.

    Why the other options are wrong

    • ASterile storage is kept at positive pressure so that air from corridors does not flow in over sterile packages.
    • BPreparation and packaging is a clean area kept at positive pressure so that contaminants do not drift in from nearby spaces.
    • DA clean holding area stores clean and sterile items, so it is kept at positive pressure like other clean spaces.

15. Question 15 of 25Easy

    A technician in the preparation and packaging area uses alcohol-based hand rub between tasks. Which technique is correct?

    1. AA. Rub the palms together briefly, then wipe off the rest with a towel
    2. BB. Rub it over all surfaces of the hands and fingers until they are dry
    3. CC. Rub it in, then rinse the hands under running water
    4. DD. Apply a small drop to the palms and let it air-dry without rubbing
    Show answer to question 15

    Answer: B. Rub it over all surfaces of the hands and fingers until they are dry

    Alcohol-based hand rub works when enough product covers every surface of the hands and fingers and is rubbed in until it dries. Wiping it off or rinsing it away shortens the contact time.

    Why the other options are wrong

    • AWiping off the product with a towel removes it before it has had time to act on all surfaces.
    • CHand rub is not rinsed off; rinsing removes the product before it has finished working.
    • DA small drop does not cover all surfaces, and rubbing is needed to spread the product.

16. Question 16 of 25Medium

    After a case, a surgeon asks the SP department to clean and sterilize a device labeled for single use so that it can be used on the next patient. The hospital does not reprocess single-use devices in house. What should the technician do?

    1. AA. Process it once with a similar reusable device's IFU and label it as reprocessed
    2. BB. Process it if the supervisor and the surgeon both sign a form accepting the risk
    3. CC. Decline to process it, and return it to the surgeon to wipe and reuse in the next case
    4. DD. Decline to process it, and refer the request to the supervisor
    Show answer to question 16

    Answer: D. Decline to process it, and refer the request to the supervisor

    A single-use device has no validated instructions for cleaning and sterilizing it again, and this hospital does not reprocess such devices. The technician declines and refers the request to the supervisor, who can explain how the hospital handles single-use devices.

    Why the other options are wrong

    • AAnother device's IFU was not validated for this one, and a reprocessed label does not make it safe.
    • BSignatures do not validate a process or meet the FDA requirements that apply to reprocessing.
    • CWiping a used device does not clean or sterilize it, and reusing it would expose the next patient to contamination.

17. Question 17 of 25Easy

    An SP manager compares the department's tray error rate and set turnaround times with those of similar hospitals in the same health system in order to set improvement targets. What is this practice called?

    1. AA. Benchmarking
    2. BB. Peer review
    3. CC. Root cause analysis
    4. DD. Value stream mapping
    Show answer to question 17

    Answer: A. Benchmarking

    Benchmarking compares a department's performance measures with those of similar departments or with best practice, showing where it stands and helping it set realistic targets.

    Why the other options are wrong

    • BPeer review is an evaluation of an individual's professional performance by colleagues, not a comparison of department measures.
    • CRoot cause analysis looks for the system causes of a specific event.
    • DValue stream mapping charts the steps and delays within one process.

18. Question 18 of 25Medium

    A technician is assigned to clean a shelf in sterile storage that holds wrapped instrument sets. Which method is correct?

    1. AA. Wipe around the sets without moving them, to limit handling
    2. BB. Spray disinfectant over the shelf and the sets, then wipe both
    3. CC. Remove the sets, clean the shelf, and let it dry before reloading
    4. DD. Remove the sets, clean the shelf, and reload while it is still damp
    Show answer to question 18

    Answer: C. Remove the sets, clean the shelf, and let it dry before reloading

    The sets are removed so that the whole shelf can be cleaned without wetting them, and the shelf must be dry before they go back, because moisture can wick through packaging and compromise sterility.

    Why the other options are wrong

    • AWiping around the sets leaves dust under them and risks getting liquid on the packages.
    • BSpraying disinfectant on sterile packages wets them, which can compromise the barrier and sterility.
    • DPlacing packages on a damp shelf lets moisture wick into the packaging.

19. Question 19 of 25Easy

    When manually mixing concentrated liquid chemical disinfectants or detergents with water, what is the correct practice to prevent splashing?

    1. AA. Add the water to the chemical slowly while stirring constantly
    2. BB. Heat the water to boiling before introducing the chemical agent
    3. CC. Pour both the chemical and water simultaneously into the basin
    4. DD. Add the chemical to the water rather than water to the chemical
    Show answer to question 19

    Answer: D. Add the chemical to the water rather than water to the chemical

    When diluting concentrated chemicals, the chemical must always be added to the water to minimize violent splashing and chemical reactions. Adding water into a concentrated chemical can cause rapid heat generation, bubbling, and dangerous splashback.

20. Question 20 of 25Hard

    A monthly audit finds that 14 of 120 sterilizer printouts from the evening shift lack the operator's initials, compared with 1 of 130 from the day shift. What is the best next step?

    1. AA. Have the evening staff initial the old printouts now so the records are complete
    2. BB. Discipline each evening technician whose printout was missing initials
    3. CC. Find out why the evening shift misses the step, fix the cause and re-audit
    4. DD. Stop auditing the evening shift, since its loads were already released
    Show answer to question 20

    Answer: C. Find out why the evening shift misses the step, fix the cause and re-audit

    An audit is useful only when it leads to action: the gap is traced to its cause, such as training or workflow on that shift, a fix is put in place, and a follow-up audit checks whether it worked. This applies the plan, do, check, act cycle to documentation.

    Why the other options are wrong

    • AInitialing printouts weeks later would make the record show a review that never happened when the loads were released.
    • BDiscipline without finding the cause does not fix a shift-wide pattern and discourages honest reporting.
    • DReleased loads are the reason the gap matters, so auditing continues until compliance is shown.

21. Question 21 of 25Hard

    Under ANSI/AAMI ST79 guidelines, what is the maximum acceptable room temperature for the sterile storage area?

    1. AA. 75°F (24°C)
    2. BB. 73°F (23°C)
    3. CC. 68°F (20°C)
    4. DD. 78°F (26°C)
    Show answer to question 21

    Answer: A. 75°F (24°C)

    ANSI/AAMI ST79 specifies that the temperature in sterile storage should not exceed 75°F (24°C) to prevent premature breakdown of sterile packaging materials and adhesive seals. Temperatures up to 73°F are typically designated for preparation and packaging, but storage allows up to 75°F.

22. Question 22 of 25Medium

    During the weekly eyewash check, a technician finds a loaded supply cart parked in front of the eyewash station in decontamination. What should the technician do?

    1. AA. Leave the cart there, since staff could push it aside in an emergency
    2. BB. Move the cart so the path to the eyewash is clear and unobstructed
    3. CC. Tape a sign to the cart asking staff to move it if the eyewash is needed
    4. DD. Write the problem on the check log and leave the cart for the supervisor
    Show answer to question 22

    Answer: B. Move the cart so the path to the eyewash is clear and unobstructed

    An eyewash must be reachable at once along a clear path, because seconds count after a chemical splash. Moving the cart fixes the hazard immediately; if blocking keeps happening, the technician also reports it so it can be prevented.

    Why the other options are wrong

    • AA worker with chemical in the eyes may not see well enough to move a loaded cart.
    • CA sign does not remove the obstruction, and a person with an eye splash may not be able to read it.
    • DRecording the problem without moving the cart leaves the eyewash blocked until someone else acts.

23. Question 23 of 25Hard

    A sterile processing manager brings together technicians and surgical suite personnel for a focused, multi-day workshop to rapidly redesign the decontamination intake workflow. What is this structured, short-duration improvement effort called?

    1. AA. Benchmarking survey
    2. BB. Kaizen event
    3. CC. Failure mode and effects analysis
    4. DD. Cross-docking protocol
    Show answer to question 23

    Answer: B. Kaizen event

    A Kaizen event (also known as a rapid improvement event) is an intensive, cross-functional project typically lasting several days to quickly solve an operational problem and eliminate waste. A failure mode and effects analysis is a prospective risk-assessment technique used to analyze how a new or existing system might fail before those failures occur.

24. Question 24 of 25Medium

    A technician fell near the cart washer and twisted her ankle. Which statement belongs in the incident report she completes?

    1. AA. I slipped on water on the floor in front of the cart washer at 10:15 a.m.
    2. BB. The floor is wet most days because housekeeping does a poor job.
    3. CC. I was probably distracted, so the accident was mostly my fault.
    4. DD. The cart washer is unsafe, and the department should replace it as soon as possible.
    Show answer to question 24

    Answer: A. I slipped on water on the floor in front of the cart washer at 10:15 a.m.

    An incident report is a factual record of what happened, where, when and who was involved, written promptly and in objective terms. It should not include opinions, blame or guesses about fault.

    Why the other options are wrong

    • BBlaming another department is an opinion, not an observed fact about this event.
    • CGuessing about fault is not a factual description; fault is decided through review, not in the report.
    • DA judgment about replacing equipment is an opinion, while the report states what happened.

25. Question 25 of 25Medium

    A technician wants to know which glove material and which kind of eyewear to use when handling a new acid descaler. Which section of its safety data sheet gives this information?

    1. AA. The section with the signal word, pictograms and hazard statements
    2. BB. The section on safe handling and storage, including incompatible materials
    3. CC. The section on symptoms after exposure and the first-aid steps to take
    4. DD. The section with exposure limits and engineering controls
    Show answer to question 25

    Answer: D. The section with exposure limits and engineering controls

    The SDS section that lists exposure limits and engineering controls, titled exposure controls and personal protection, also names the PPE needed, such as the glove material and the type of eye or face protection.

    Why the other options are wrong

    • AThe hazard identification section gives the classification, signal word, pictograms and general precautionary statements, not the specific glove material or eye protection.
    • BThe handling and storage section covers safe handling practices and storage conditions, not the specific PPE to wear.
    • CThe first-aid section tells what to do after an exposure, not which PPE prevents one.
