Which of the following is recommended to prevent look-alike/sound-alike medication errors?

• A. Barcode scanning when available
• B. All of the above
• C. Use standardized naming
• D. Verify medication with the patient

Answer: (B)

Look-alike/sound-alike medication errors happen when drugs have very similar names or packaging, leading to the wrong drug being selected or given. To prevent these errors, use several safeguards in combination, because each one protects a different part of the process. Barcode scanning when available provides an objective check at the point of dispensing or administration, ensuring the medication matches the order and the patient’s records. Standardized naming helps everyone involved—prescribers, pharmacists, and nurses—distinguish similar drug names during selection, labeling, and administration, reducing mix-ups. Verifying the medication with the patient brings the patient into the safety process, giving them a chance to confirm they are receiving the correct medicine. When these methods are used together, they create multiple layers of protection that collectively reduce the risk of LASA errors. If barcode scanning isn’t available, the other safeguards remain valuable, and when scanning is available, it adds an important extra check.
