Safe Insulin Administration When Barcode Scanner Fails

Scenario

The barcode system is temporarily offline. You must administer Humalog 6 units subcutaneously to a patient before a meal.

Question: Describe your steps to ensure patient safety and correct administration.

Best Practice Answer

• Verify manually:
  • Two patient identifiers (name, MRN).
  • Medication, dose, route, timing, and indication (the five rights).
• Independent double-check:
  • Another RN confirms vial type and dose using MAR.
• Inspect and prepare:
  • Confirm U-100 syringe, correct vial (Humalog vs Lantus).
  • Draw correct dose, avoid air bubbles.
• Administer and document:
  • Rotate injection site, reassess BG in 15–30 min.
  • Chart manually and reconcile once system is up.

Interview Tip: Mention fallback safety procedures and “just culture” if a near-miss occurs.
