Inventory Management Practice Questions

20 practice questions with detailed explanations — aligned to the Sterile Processing Technician Exam.

  1. Q1.The 'Par Level' system of inventory distribution relies on:

    A.Exchanging a full cart for a used one
    B.Ordering items only when needed
    C.Establishing a standard stock level for each item and replenishing only what was used to return to that level
    D.The surgeon's preference card
