This learning activity examines pediatric respiratory distress through a developmental lens for nurses caring for children in acute and critical care settings. It integrates structured assessment tools, including the Pediatric Assessment Triangle and Pediatric Early Warning Score trending, with common etiologies across age groups, current evidence-based interventions such as high-flow nasal cannula therapy and updated RSV prevention strategies, and the newly updated 2025 pediatric resuscitation guidelines. The content emphasizes early recognition of the distress-to-failure continuum, the limits of relying on any single assessment tool or vital sign, and the role of family-centered communication in identifying subtle deterioration, equipping nurses to intervene before compensation fails.
