1. Question 1 of 25Medium

   A facility sprinkler head accidentally discharges water over several shelves of wrapped surgical instrument trays in the sterile storage room. How must these affected items be managed?

   1. AA. Consider all packages contaminated, disassemble the instruments, and repeat the full reprocessing cycle
   2. BB. Strip the damp outer wrapper, apply a new sterile barrier system, and run an immediate-use steam cycle
   3. CC. Inspect the internal chemical indicators and re-sterilize the intact packs without cleaning the instruments
   4. DD. Dry the external wrappers with sterile towels and place the trays into an aerator cabinet before issuing
   Show answer to question 1

   Answer: A. Consider all packages contaminated, disassemble the instruments, and repeat the full reprocessing cycle

   Any contact with moisture, including sprinkler discharge, compromises packaging barriers and allows microorganisms to wick inside, rendering contents unsterile. The items cannot simply be dried or re-sterilized in wet or contaminated packaging; they must be disassembled, decontaminated, re-inspected, repackaged, and completely reprocessed.

2. Question 2 of 25Medium

   An FDA recall is initiated for a commercially packaged skin prep tray due to a typographical error on the box that does not affect product integrity, sterility, or patient safety. Which recall classification applies?

   1. AA. Class I
   2. BB. Class II
   3. CC. Safety alert
   4. DD. Class III
   Show answer to question 2

   Answer: D. Class III

   A Class III recall occurs when a product violates FDA labeling or manufacturing laws but is not likely to cause adverse health consequences to patients. Class I and Class II recalls are incorrect because both indicate potential physical harm to patients ranging from reversible injury to death.

3. Question 3 of 25Easy

   Department policy, based on AAMI guidance, requires sterile storage shelving to stand at least 2 inches (5 cm) away from outside walls. What is the main reason for this clearance?

   1. AA. Moisture can condense on outside walls and wet packages that touch them
   2. BB. Outside walls carry the sprinkler pipes, which need a clear spray path around them
   3. CC. The gap lets staff wipe behind the shelving without moving packages
   4. DD. The gap keeps packages from blocking the room's supply air vents
   Show answer to question 3

   Answer: A. Moisture can condense on outside walls and wet packages that touch them

   Outside walls can be warmer or cooler than the room, so condensation may form on them. Keeping shelving away from these walls prevents moisture from wicking into packages and compromising their sterility.

   Why the other options are wrong

   • BSprinkler clearance is measured beneath the sprinkler heads, not from the walls.
   • CA gap this narrow is not designed as cleaning access; its purpose is protection from wall moisture.
   • DThe wall clearance concerns moisture from outside walls, not the location of supply air vents.

4. Question 4 of 25Medium

   A technician completes a cycle count of specialty vascular grafts and finds eight units on the shelf, but the computerized inventory management system indicates twelve units should be on hand. What is the immediate correct action?

   1. AA. Adjust the computer balance to eight immediately without conducting an investigation
   2. BB. Change the product shelf label minimum reorder point to reflect eight units
   3. CC. Write off four units as damaged and request an emergency purchase order
   4. DD. Perform a recount and review recent transaction records before adjusting inventory
   Show answer to question 4

   Answer: D. Perform a recount and review recent transaction records before adjusting inventory

   When a discrepancy is identified during a cycle count, the technician must first verify the physical count and review recent issues, receipts, or transfers to determine if unposted transactions caused the variance. Adjusting the system balance immediately without verification can mask processing errors, misplacements, or theft. Altering par levels or writing off items prematurely bypasses standard inventory reconciliation procedures.

5. Question 5 of 25Medium

   To keep matching instruments together, a technician wraps a rubber band around several sterile peel pouches before placing them in a storage bin. What is the main problem with this practice?

   1. AA. The band can crease or compress the pouches and put strain on the seals
   2. BB. The band can trap moisture between pouches unless the bin is vented
   3. CC. The band can rub the color off the indicator printed on each pouch
   4. DD. Opening one pouch in the bundle means the other pouches need reprocessing too
   Show answer to question 5

   Answer: A. The band can crease or compress the pouches and put strain on the seals

   Rubber bands squeeze and bend peel pouches, which can create creases, channels or breaks in the seals and compromise the sterile barrier. Pouches are stored loosely, without bands, in bins that do not crush them.

   Why the other options are wrong

   • BTrapped moisture is not the main hazard of a band, and a vented bin does not prevent seal damage.
   • CA band does not normally remove a printed indicator; the hazard is creasing and strain on the seals.
   • DEach pouch is a separate package, so opening one does not affect the others; the hazard is the band's pressure on the seals.

6. Question 6 of 25Easy

   Where should the break-out area for unpacking incoming external shipping boxes be located?

   1. AA. Directly inside the sterile storage area near the main exit doors
   2. BB. In an area physically separate from clean assembly and sterile storage
   3. CC. Inside the decontamination area adjacent to the ultrasonic cleaners
   4. DD. Directly on the clean assembly side adjacent to packaging workstations
   Show answer to question 6

   Answer: B. In an area physically separate from clean assembly and sterile storage

   The break-out area must be physically separate from both clean assembly and sterile storage areas to prevent airborne particulates, dust, and debris from contaminating sterile goods. Locating the break-out area inside clean assembly or sterile storage introduces foreign matter into controlled environments. Decontamination is also inappropriate because heavy bioburden and airborne aerosol contaminants could compromise incoming clean products.

7. Question 7 of 25Medium

   To reach a heavy wrapped tray at the back of a wire shelf, a technician grabs its front edge and slides it across the wires toward herself. What is the main risk of this practice?

   1. AA. The tray's internal indicator may change color from the friction
   2. BB. Sliding can shift the instruments inside so they no longer match the count sheet
   3. CC. Sliding across the wires can loosen the closure tape so the wrap falls open
   4. DD. The wire can scuff, snag or tear the wrap as the tray is dragged
   Show answer to question 7

   Answer: D. The wire can scuff, snag or tear the wrap as the tray is dragged

   Dragging a package across shelving creates friction that can abrade, snag or tear the wrap, sometimes in ways that are hard to see. Sterile packages are lifted and carried rather than slid.

   Why the other options are wrong

   • AChemical indicators react to sterilization conditions, not to the friction of handling.
   • BInstruments may shift, but none leave the tray; the main hazard is to the wrap, which the wire can tear.
   • CTape seldom loosens from sliding; abrasion of the wrap by the wire is the main hazard.

8. Question 8 of 25Medium

   A vendor delivers a loaner instrument set the evening before a scheduled spine case. The representative says the set was cleaned and sterilized at another hospital that morning and is ready to use. What should SPD do?

   1. AA. Send it to the OR as delivered, since it was sterilized that morning
   2. BB. Run it through a sterilization cycle, since it was already cleaned
   3. CC. Process it fully, from cleaning through sterilization, before its use
   4. DD. Store it in sterile storage until the case, since its wrap is intact
   Show answer to question 8

   Answer: C. Process it fully, from cleaning through sterilization, before its use

   The receiving facility cannot verify how a loaner set was handled elsewhere, so after check-in it is cleaned, inspected, packaged and sterilized following the set's IFU before use.

   Why the other options are wrong

   • AProcessing at another facility cannot be verified, and the set has been handled and transported since then.
   • BCleaning done elsewhere cannot be verified, and sterilization is not reliable on items that may not be clean.
   • DAn intact wrap from another facility does not show that the set was properly processed.

9. Question 9 of 25Medium

   A transporter pushing a cart of bagged soiled linen wants to cut through the sterile storage room because it is the shortest way to the service elevator. What should the technician tell him?

   1. AA. He may go through if the soiled linen bags are tied and the cart is covered
   2. BB. He may go through if he keeps the cart in the center aisle, away from shelves
   3. CC. He must take another route, since soiled items do not pass through this room
   4. DD. He must wait while the technician drapes the room's open shelves with sheets
   Show answer to question 9

   Answer: C. He must take another route, since soiled items do not pass through this room

   Sterile storage is a limited-access area, and traffic is controlled so that soiled items and unnecessary people stay out. Soiled linen must travel by a route that does not pass through sterile storage.

   Why the other options are wrong

   • AClosed bags and a cover reduce some risk, but soiled items still do not belong in the sterile storage room.
   • BKeeping to the center aisle still brings soiled items and extra traffic through a clean, restricted area.
   • DDraping the shelves does not make it acceptable to move soiled items through sterile storage.

10. Question 10 of 25Medium

    Department policy, based on AAMI guidance, requires sterile items to be stored at least 18 inches (46 cm) beneath the sprinkler heads. During rounds in sterile storage, a technician finds wrapped trays on a top shelf whose tops sit about 10 inches under a sprinkler head. What should the technician do?

    1. AA. Leave the trays in place and report the top shelf so it can be lowered later
    2. BB. Move the trays to a lower shelf within the limit and report the top shelf
    3. CC. Send the trays back for reprocessing, since storing them that high ends their sterility
    4. DD. Push the trays to the back of the shelf, away from the sprinkler head
    Show answer to question 10

    Answer: B. Move the trays to a lower shelf within the limit and report the top shelf

    The clearance beneath sprinkler heads is a fire safety requirement that keeps stored items from blocking the spray. The trays belong on a shelf that meets the limit, and the top shelf is reported so it can be lowered or taken out of use.

    Why the other options are wrong

    • AReporting the shelf is right, but the trays stay in the clearance zone and block the spray until the shelf is changed.
    • CThe clearance is a fire safety rule; intact, dry packages do not lose sterility by sitting too high.
    • DThe 18-inch limit applies to the top of all storage in the room, not just directly under a head, so sliding the trays back does not lower them.

11. Question 11 of 25Hard

    A department uses event-related shelf life for the items it sterilizes. In storage, a technician finds a commercially sterile suture pack that is intact and dry, but its printed use-by date passed last week. What should the technician do?

    1. AA. Keep it in stock, since event-related policy overrides the use-by date
    2. BB. Resterilize it in the department and return it to the same storage bin
    3. CC. Remove it from stock, since the product's use-by date still applies
    4. DD. Keep it in stock, moved to the front of the bin so it is used first
    Show answer to question 11

    Answer: C. Remove it from stock, since the product's use-by date still applies

    Event-related shelf life applies to items the department sterilizes. A purchased product's use-by date reflects the manufacturer's testing of the product and its materials, so expired items are removed from stock and handled through the facility's return or disposal process.

    Why the other options are wrong

    • AThe department's shelf-life policy does not override the expiration date on a purchased product.
    • BA purchased sterile product is not resterilized in-house unless its manufacturer provides validated instructions.
    • DMoving it forward would send an expired product to patient care.

12. Question 12 of 25Hard

    Use of IV start kits on a medical unit has risen sharply, although the number of patients has not changed. While restocking, the technician finds kits stashed in drawers and closets around the unit. What is the main concern, and the best response?

    1. AA. Patient needs have grown, so the technician should raise the PAR level
    2. BB. Hidden stock can expire and distort usage data, so it should be reported
    3. CC. Extra stock on the unit saves SPD trips, so no action is needed
    4. DD. Kits are being taken for personal use, so the technician should report a theft to security
    Show answer to question 12

    Answer: B. Hidden stock can expire and distort usage data, so it should be reported

    Hoarding often starts when staff do not trust the supply system. Hidden stock is not rotated, so it can expire or be damaged, and it inflates usage data; reporting it lets the supervisor work with the unit on the cause and the right PAR level.

    Why the other options are wrong

    • AThe census is unchanged and stockpiles were found, so the rise reflects hoarding, not greater patient need.
    • CStockpiles tie up money, escape rotation and lead to expired or damaged items.
    • DKits stashed around the unit point to hoarding by staff who distrust the supply system, not to theft.

13. Question 13 of 25Medium

    While unpacking a delivery, a technician finds that one side of the shipping carton was crushed and several sterile drape packs inside have punctures and torn corners. What should be done with the damaged packs?

    1. AA. Tape over the damaged areas, shelve the packs and report the damage to the vendor
    2. BB. Shelve the packs, since the maker sterilized the drapes inside
    3. CC. Keep the packs out of stock and report them as damaged on receipt
    4. DD. Repackage the drapes in-house and sterilize them in the SPD
    Show answer to question 13

    Answer: C. Keep the packs out of stock and report them as damaged on receipt

    Punctures and tears break the sterile barrier, so the contents are no longer considered sterile. Damaged packs are kept out of stock and reported so they can be returned to the vendor or replaced.

    Why the other options are wrong

    • AReporting is right, but tape does not restore a sterile barrier once a package has been punctured or torn.
    • BThe maker's sterilization no longer counts once the packaging has been breached.
    • DCommercial products are not reprocessed in-house unless their manufacturer provides validated instructions.

14. Question 14 of 25Easy

    A unique device identifier (UDI) on a device label is made up of a device identifier and a production identifier. What does the production identifier carry?

    1. AA. The labeler and the specific version or model of the device
    2. BB. Details such as the lot or serial number and the expiration date
    3. CC. The hospital's own item number and the device's assigned shelf location
    4. DD. The name of the department that ordered and received the device
    Show answer to question 14

    Answer: B. Details such as the lot or serial number and the expiration date

    The production identifier is the variable part of the UDI and carries production details such as the lot or batch number, serial number, expiration date and manufacturing date. These details let a facility trace specific units during a recall.

    Why the other options are wrong

    • AThe labeler and the version or model are carried by the device identifier, the fixed part of the UDI.
    • CInternal item numbers and locations are assigned by the hospital and are not part of the UDI.
    • DThe UDI is assigned by the labeler and does not identify the buyer or ordering department.

15. Question 15 of 25Easy

    A clinical utility room has an established par level of 24 sterile dressing trays. During morning rounds, the Central Service technician counts 7 trays remaining on the shelf. How many trays must the technician pick and deliver to meet the required replenishment?

    1. AA. 31 trays
    2. BB. 24 trays
    3. CC. 7 trays
    4. DD. 17 trays
    Show answer to question 15

    Answer: D. 17 trays

    Under a par-level system, the replenishment quantity equals the established par level minus the count on hand (24 minus 7 equals 17 trays). Delivering 24 trays would exceed the target storage limit and overstock the clinical shelf.

16. Question 16 of 25Medium

    How does a non-stock purchase fundamentally differ from a consignment item?

    1. AA. A non-stock item is exempt from purchase order and receiving documentation
    2. BB. A non-stock item remains the property of the vendor even after implantation
    3. CC. A non-stock item is purchased directly, whereas a consignment item is paid for only after use
    4. DD. A non-stock item is maintained on automated par-level exchange carts
    Show answer to question 16

    Answer: C. A non-stock item is purchased directly, whereas a consignment item is paid for only after use

    Non-stock items are purchased by the facility when ordered, with ownership transferring upon receipt, whereas consignment items remain vendor-owned property stored on-site until opened or consumed. Neither category is exempt from receiving documentation or tracking.

17. Question 17 of 25Hard

    A technician notices that several wrapped orthopedic instrument sets are stacked on top of one another on an open wire shelf. Why is this practice unacceptable?

    1. AA. The top set creates trapped moisture beneath the lower wrap
    2. BB. The weight of the top set can compress, abrade, or puncture the wrapper
    3. CC. Stacking changes the temperature of the storage area microclimate
    4. DD. The stacking of sets traps residual ethylene oxide gas inside the packaging
    Show answer to question 17

    Answer: B. The weight of the top set can compress, abrade, or puncture the wrapper

    Wrapped instrument trays should not be stacked because the downward weight and friction can cause punctures, pressure marks, or tears in the wrapping material, compromising sterility. While rigid containers may be stacked if validated by the manufacturer, wrapped trays should be placed side by side on shelves.

18. Question 18 of 25Hard

    Usage records show that a unit runs out of suction canisters two days before each weekly restock, while sterile dressing kits on the same unit keep expiring on the shelf. What is the best response?

    1. AA. Keep both PAR levels as they are, since usage records vary week to week
    2. BB. Raise the canister PAR level now and leave the dressing kit level as it is
    3. CC. Report the canister shortages, and accept expired kits as a normal cost of stocking
    4. DD. Report the usage pattern so each PAR level can be reviewed and adjusted
    Show answer to question 18

    Answer: D. Report the usage pattern so each PAR level can be reviewed and adjusted

    PAR levels should match actual use. Running out of canisters points to a level that is too low, and expiring kits point to one that is too high, so each level is reviewed with the unit and supervisor and adjusted in its own direction.

    Why the other options are wrong

    • AThe records show a steady pattern in both directions, not random weekly variation.
    • BFixing only the canisters leaves the kit level too high, so the kits keep expiring.
    • CExpired kits show a PAR level that is too high, which wastes money and must be reviewed as well.

19. Question 19 of 25Easy

    What is the correct physical technique for removing a heavy wrapped instrument tray from a wire sterile storage shelf?

    1. AA. Lift the tray completely clear of the shelf surface before bringing it forward
    2. BB. Tilt the tray onto its side edge to decrease surface contact while pulling
    3. CC. Slide the tray toward the front edge using the lower folds of the wrapper
    4. DD. Grasp the wrapper corners and pull steadily along the shelf wire
    Show answer to question 19

    Answer: A. Lift the tray completely clear of the shelf surface before bringing it forward

    Staff must lift the wrapped tray completely off the shelf surface before moving it forward to prevent the packaging material from tearing, abrading, or snagging. Sliding or dragging a wrapped tray across wire or solid shelves creates friction that easily punctures the sterile wrap. Tilting the set or pulling on wrapper corners stresses the wrap folds and risks breaching the sterile barrier.

20. Question 20 of 25Medium

    Orthopedic screws are kept in the SPD on consignment from a vendor. During a case, three of the screws are implanted. What should happen next?

    1. AA. Report the use, with lot or serial numbers, so the vendor bills and restocks
    2. BB. Wait for the vendor's next scheduled count to reveal the missing screws
    3. CC. Report the use to the vendor once the rest of the consigned screws start to run low
    4. DD. Reorder three screws through the department's usual PAR restocking
    Show answer to question 20

    Answer: A. Report the use, with lot or serial numbers, so the vendor bills and restocks

    Consigned items belong to the vendor until they are used. Reporting each use, with lot or serial numbers, lets the vendor bill the facility and replace the stock, and keeps implant traceability intact.

    Why the other options are wrong

    • BWaiting delays billing and replacement and could leave too few screws for the next case.
    • CEach use is reported promptly; holding reports until stock runs low delays billing and restocking and weakens lot tracking.
    • DConsigned screws are vendor-owned and replaced by the vendor after each reported use, so a PAR reorder buys extra stock outside the agreement.

21. Question 21 of 25Easy

    An SPD storeroom labels every bin with an aisle, section, shelf and bin code, and the same code prints next to each item on restocking and order lists. What is the main benefit of this item locator system?

    1. AA. Items can be stored with no need to check their use-by dates
    2. BB. Sterile items can be stored closer to both the floor and the ceiling
    3. CC. The location code can replace catalog numbers on the labels
    4. DD. Staff can find, pick and restock each item quickly and correctly
    Show answer to question 21

    Answer: D. Staff can find, pick and restock each item quickly and correctly

    A locator system gives every item a fixed, labeled home that matches its code on lists and screens. Staff find items faster, put them back in the right place and make fewer picking errors.

    Why the other options are wrong

    • ALocation codes do not track dates, so use-by dates still need to be checked.
    • BClearances from the floor and ceiling apply whatever labeling system is used.
    • CA location code tells where an item is kept, not exactly which product it is.

22. Question 22 of 25Easy

    A hospital moves to a just-in-time system in which its distributor delivers supplies in small amounts shortly before they are needed. What is the main advantage of this system?

    1. AA. Less money is tied up in stock, and less storage space is used
    2. BB. The hospital depends less on its distributor's delivery schedule
    3. CC. Large orders bring a lower price for each item that is purchased
    4. DD. Units can keep generous extra supplies on hand for emergencies
    Show answer to question 22

    Answer: A. Less money is tied up in stock, and less storage space is used

    Just-in-time delivery keeps on-hand inventory low, so less money is tied up in supplies and less storage space is needed. The trade-off is a greater dependence on reliable deliveries.

    Why the other options are wrong

    • BThe system depends more on the distributor, since little stock is kept to cover a late delivery.
    • CBulk-buying discounts come from large orders, which is the opposite of just-in-time.
    • DKeeping large extra supplies on units works against the low-stock goal of just-in-time.

23. Question 23 of 25Hard

    A facility uses event-related sterility for wrapped sets, but a customized procedure tray contains an internal commercially prepared disposable component with a stated manufacturer expiration date. How must the assembled tray's shelf life be determined?

    1. AA. The tray is automatically assigned a twelve-month expiration date from assembly
    2. BB. The tray must be labeled with the expiration date of the component that expires first
    3. CC. The tray expiration date is calculated strictly from the sterilization cycle parameters
    4. DD. The tray maintains indefinite event-related sterility regardless of internal contents
    Show answer to question 23

    Answer: B. The tray must be labeled with the expiration date of the component that expires first

    When an assembled pack includes components with manufacturer-assigned expiration dates, the entire pack must reflect the expiration date of the earliest-expiring component inside. Treating the pack as indefinitely event-related is unsafe because internal components, such as chemical adhesives or specialized disposable items, degrade over time irrespective of external barrier integrity.

24. Question 24 of 25Hard

    A hospital discontinues a specialty surgical program, leaving several expensive customized procedure packs on sterile storage shelves with no anticipated usage. What is the most appropriate initial step for managing this obsolete stock?

    1. AA. Open and disperse the individual instruments into general inventory sets to mask the excess count
    2. BB. Repackage the custom trays into smaller sets without consulting the surgical service committee
    3. CC. Collaborate with materiel management and surgical leaders to evaluate return, transfer, or disposition options
    4. DD. Discard all packs into biohazardous waste bins to free up necessary storage shelf space immediately
    Show answer to question 24

    Answer: C. Collaborate with materiel management and surgical leaders to evaluate return, transfer, or disposition options

    Managing obsolete stock requires cross-departmental coordination with materiel management and clinical leadership to investigate vendor buybacks, transfers to affiliate facilities, or formal write-offs. Dispersing specialized items into general sets without review can create non-standard sets, and discarding them immediately causes unnecessary financial loss.

25. Question 25 of 25Hard

    SPD receives a recall notice for one lot of sterile gauze sponges. Packages from that lot are in central storage, on two nursing units and on case carts already built for this afternoon's surgeries. What should the technician do first?

    1. AA. Pull the lot from central storage now and from the case carts after surgery
    2. BB. Pull the lot from storage and the units now, and have OR staff check carts at setup
    3. CC. Find and remove every package of the lot from all locations, including carts
    4. DD. Inspect the lot's packages and pull those that look damaged or discolored
    Show answer to question 25

    Answer: C. Find and remove every package of the lot from all locations, including carts

    A recall response starts by finding every package of the affected lot wherever it is stored or staged, including case carts that are already built, and removing it from use. Removed items are quarantined and the actions recorded while replacements are found.

    Why the other options are wrong

    • ALeaving recalled items on today's case carts could put them into use during surgery.
    • BLeaving recalled sponges on built carts until setup risks their use; the carts are cleared now.
    • DA recall covers every package of the lot, however normal the packages look.
