Method: qualitative, descriptive and exploratory study, conducted in a public hospital in Pernambuco, Brazil. Six pediatric nurses participated. Data collection was conducted between November and February 2021 through semi-structured interviews; data analysis was conducted through content investigation. Results: three categories were identified from the analysis of the results: nurses' perception of patient safety, patient identification barriers in the pediatric unit, and identification wristbands: a strategy to mitigate errors in the pediatric unit. Final Considerations: it was possible to realize that nurses believe in the importance of patient identification as a strategy to minimize the occurrence of medication-related errors and emphasize that this act provides greater safety to professionals during the execution of procedures.
