OBJECTIVE: to identify the challenges pediatric nursing workers face as a result of the COVID-19 pandemic. METHOD: qualitative study, using a semi-structured electronic form applied to nursing workers from pediatric services in the state of Rio de Janeiro, Brazil. Data were submitted to lexicographic analysis using the Interface de R pour Analyses Multidimensionnelles de Textes et de Questionnaires, Word Cloud technique, and Similitude Analysis. RESULTS: different challenges concerning the COVID-19 pandemic were reported, including the need to promote comprehensive and quality care while being concerned with protecting oneself and others, with an emphasis on fear. A lack of protective equipment, training, diagnostic tests, and knowledge/information concerning the disease was also reported, in addition to a reduced number of nursing workers and a lack of appreciation for the profession. CONCLUSION: managerial guidelines need to be adopted for properly allocating human and material resources in the health field, including the pediatric services, in addition to providing training on standard precautions. Actions to encourage, value, motivate, and support the nursing staff are needed during and after the pandemic to protect the physical and mental health of these professionals.
