Symptom narrative

Provider ordered Engerix-B (Hep B). Nurse prepared, had a second member of the team perform a second check, and administered the Pediatric variation, instead of the adult variation that was ordered. She was made aware of the error when she was documenting, as the lot number was not available to select. Nurse notified the provider who advised patient to return in a week to receive the adult dose. Patient notified and scheduled to return. The nurse advised that being new to primary care, was unaware that there was an adult and pediatric dose. Noted that the syringe is not clearly marked as adult or pediatric, although the packaging does indicate which it is.
