What is the purpose of barcode scanning in pharmacy?

• A. To track inventory levels for automated replenishment.
• B. To encrypt patient data during transactions.
• C. To verify medications and enhance accuracy in dispensing.
• D. To replace the need for pharmacist verification.

Answer: (C)

Barcode scanning is used to confirm the medication being placed into the patient’s order matches the prescription, which directly enhances dispensing accuracy. Each drug has a barcode that conveys its identity (and often lot and expiration), and the scanning system cross-checks this information against the prescription data and the patient’s profile. When the scanned product matches what’s on the order, the pharmacist or technician can proceed with confidence; if there’s a mismatch, the system can flag it before the drug is dispensed, helping prevent wrong-drug or wrong-strength errors. While barcode scanning can also assist with inventory tracking and data capture, its primary purpose in the dispensing process is to verify medications and improve accuracy. It does not encrypt patient data or replace the pharmacist’s verification step.
