1. Inventory and Storage

   Question 1: AAMI ST79 recommends that sterile storage areas be kept at:

   • A) Below freezing to preserve sterility
   • B) A temperature not exceeding 75 degrees F (24 degrees C), with humidity controlled
   • C) Above 90 degrees F to discourage pests
   • D) Whatever temperature the hallway happens to be
   Answer and explanation

   Correct answer: B

   Heat and humidity degrade packaging materials and encourage microbial growth. Keeping storage at or below 75 degrees F with controlled humidity protects the sterile barrier until the package is opened. (Source: AAMI ST79)

2. Inventory and Storage

   Question 2: Cardboard shipping boxes are not allowed in sterile storage because:

   • A) They are too heavy for the shelves
   • B) They shed dust and fibers and can harbor pests
   • C) They are the wrong color
   • D) They block the sprinkler heads
   Answer and explanation

   Correct answer: B

   Corrugated cardboard generates particulate that settles on packages and shelving, and it can carry insects into a clean environment. Supplies are removed from shipping cartons before entering sterile storage. (Source: AAMI ST79)

3. Inventory and Storage

   Question 3: Open-wire shelving is preferred in sterile storage because it:

   • A) Is cheaper than any alternative
   • B) Allows air circulation and prevents dust from settling on packages
   • C) Holds more weight than solid shelving
   • D) Never needs cleaning
   Answer and explanation

   Correct answer: B

   Solid shelves trap dust and block airflow, while wire shelving lets air move and particles fall through instead of collecting under packages. Shelving is still cleaned on a schedule. (Source: AAMI ST79)

4. Inventory and Storage

   Question 4: In inventory management, a par level is:

   • A) The maximum the budget allows
   • B) The predetermined stock quantity that triggers reordering when reached
   • C) A type of sterilizer
   • D) The number of staff on each shift
   Answer and explanation

   Correct answer: B

   Par levels turn reordering from guesswork into a system: when stock drops to the par quantity, an order goes out. Set correctly, par levels prevent both stockouts and overstock. (Source: HSPA CRCST exam content outline)

5. Inventory and Storage

   Question 5: A sterile package past its expiration date must be:

   • A) Used anyway, since sterility is event-related
   • B) Not used; it is reprocessed or discarded per facility policy
   • C) Used only for training
   • D) Re-dated with a new label
   Answer and explanation

   Correct answer: B

   Some facilities assign expiration dates based on packaging materials or policy. Once the date passes, the package cannot be trusted for patient use, so it is pulled, reprocessed, or discarded according to policy. (Source: AAMI ST79)

6. Inventory and Storage

   Question 6: Clean and soiled items must be transported:

   • A) In the same cart to save trips
   • B) Separately, so soiled items never contaminate clean ones
   • C) Only by the nursing staff
   • D) In open bins for visibility
   Answer and explanation

   Correct answer: B

   Mixing clean and dirty in one cart defeats the entire decontamination workflow. Separate carts, and ideally separate routes or times, keep sterile and clean items from contacting contaminants in transit. (Source: AAMI ST79)

7. Inventory and Storage

   Question 7: When receiving sterile supplies from a vendor, the technician must:

   • A) Shelve everything immediately without checking
   • B) Inspect packages for damage and verify the shipment against the purchase order
   • C) Open every package to check the contents
   • D) Refuse all vendor deliveries
   Answer and explanation

   Correct answer: B

   Damaged packaging may mean compromised sterility, and wrong items create stockouts later. Inspection at receiving catches problems before supplies enter storage, and the purchase order confirms the right products and quantities arrived. (Source: HSPA CRCST exam content outline)

8. Inventory and Storage

   Question 8: Patient care equipment, such as IV pumps and monitors, is best managed through:

   • A) Leaving equipment wherever it was last used
   • B) A centralized system that tracks clean and soiled equipment separately
   • C) Letting each unit clean its own equipment with no oversight
   • D) Discarding equipment after each patient
   Answer and explanation

   Correct answer: B

   A central equipment pool with separate clean and dirty flows guarantees the next patient gets decontaminated equipment. Tracking also supports maintenance schedules and par levels for the fleet. (Source: HSPA CRCST exam content outline)

9. Inventory and Storage

   Question 9: A materials management information system (MMIS) is used to:

   • A) Sterilize instruments
   • B) Track inventory levels, usage, purchasing, and costs
   • C) Schedule surgeries
   • D) Train new employees
   Answer and explanation

   Correct answer: B

   The MMIS is the department data backbone for supplies: what is on hand, what was used, what was ordered, and what it cost. Good data drives par levels, budgets, and recall traceability. (Source: HSPA CRCST exam content outline)

10. Inventory and Storage

    Question 10: In a two-bin (kanban) inventory system, a reorder is triggered when:

    • A) Both bins are empty
    • B) The first bin is empty and staff begin using the second bin
    • C) The fiscal year ends
    • D) A manager remembers to order
    Answer and explanation

    Correct answer: B

    The two-bin system is visual and foolproof: the working bin empties, the reserve bin opens, and the empty bin itself is the reorder signal. Stock arrives before the reserve runs out. (Source: HSPA CRCST exam content outline)

11. Inventory and Storage

    Question 11: Loaner instrument trays must be documented in:

    • A) No records, since the vendor owns them
    • B) A loaner log capturing the vendor, tray identification, and processing records
    • C) The patient chart
    • D) A sticky note on the tray
    Answer and explanation

    Correct answer: B

    Loaners carry the same traceability burden as hospital-owned sets. The log ties each tray to its vendor, its decontamination and sterilization records, and the case it served, which is essential if a recall ever touches that tray. (Source: HSPA CRCST exam content outline)

12. Inventory and Storage

    Question 12: Sterile supplies stored in procedure rooms or satellite areas must be kept:

    • A) On open countertops for easy access
    • B) In closed cabinets or carts that protect them from dust, moisture, and handling
    • C) On the floor under the sink
    • D) In cardboard boxes on the windowsill
    Answer and explanation

    Correct answer: B

    Satellite storage faces the same contamination risks as central storage with less environmental control. Closed cabinets shield packages from dust, splashes, and casual handling that would compromise the sterile barrier. (Source: AAMI ST79)

13. Inventory and Storage

    Question 13: Soiled case carts returning from the OR must travel:

    • A) Uncovered, so everyone can see they are dirty
    • B) Covered, on a designated route that keeps them separate from clean transport
    • C) Through the sterile storage area as a shortcut
    • D) Only after midnight
    Answer and explanation

    Correct answer: B

    Covered carts contain contaminants and odors, and a designated dirty route prevents soiled carts from crossing paths with clean or sterile transport. Separation in transit is part of the one-directional workflow. (Source: AAMI ST79)

14. Inventory and Storage

    Question 14: High inventory turnover is desirable because it:

    • A) Looks impressive on reports
    • B) Reduces expired stock, frees storage space, and lowers carrying costs
    • C) Means the department never needs to order
    • D) Eliminates the need for par levels
    Answer and explanation

    Correct answer: B

    Supplies sitting on shelves tie up money, expire, and consume space. Steady turnover keeps stock fresh and the budget lean, while par levels guard against the stockouts turnover alone cannot prevent. (Source: HSPA CRCST exam content outline)

15. Inventory and Storage

    Question 15: When the OR requests a STAT tray, distribution must:

    • A) Send the first tray on the shelf without checking it
    • B) Prioritize the request while still verifying the tray is complete, sterile, and correct for the case
    • C) Tell the OR to wait for the next routine delivery
    • D) Send an unsterile tray to save time
    Answer and explanation

    Correct answer: B

    Urgency never overrides verification. The STAT request jumps the queue, but the tray is still checked against the count sheet and confirmed sterile and intact, because a wrong or compromised tray in a rush case helps no one. (Source: HSPA CRCST exam content outline)
