Objective: to understand how nurses assess the implementation of therapeutic play by the nursing staff in the care provided to children. Method: qualitative study addressing nurses providing pediatric care in hospitals located in five Brazilian regions. Face-to-face meetings were held with nine focal groups between January and August 2018. The sessions lasted two hours on average and were audio-recorded and transcribed verbatim. Data were analyzed through inductive thematic analysis. Results: 52 nurses reported their perspectives regarding play and therapeutic play implemented in the care provided to children, which revealed The power of Play-Care implemented in nursing care: advancements and challenges and its subthemes: using puppets/dolls and dramatizing procedures; using distraction strategies to perform the procedures; wearing colorful and fun uniforms; recognizing the power of play in nursing care; and barriers challenging the connection between play and care in nursing practice. Conclusion: the power of Play-Care is manifested in the routine of nursing care through playful attitudes; however, these attitudes appear to be individual initiatives rather than systematized in the nursing process. Hence, there is a need to expand the possibilities of teaching this topic by promoting training programs, including practical activities and virtual learning environments.
