What method does a hospital use to control inventory and patient charges for supplies?

• A. Central processing unit
• B. Bar coding
• C. Graphic sheet
• D. Use of passwords

Answer: (B)

Bar coding is the method used. By placing barcodes on supplies and on patient identifiers, staff scan items at the point of use and at receipt. Each scan updates real-time records that tie the exact quantity used to the patient’s bill and to current inventory levels. This automates charge capture and stock management, reduces manual data entry and errors, and helps ensure accurate billing.

The other options don’t fit this purpose: a central processing unit is a computer component rather than a system for tracking inventory and charges; a graphic sheet isn’t a recognized method for managing supplies or linking them to patient accounts; and passwords relate to security access, not inventory control or patient billing.
