Which outcome criterion would the nurse prioritize for a child with cystic fibrosis who has ineffective airway clearance?

Prioritizing respiratory outcomes is crucial for a child with cystic fibrosis, especially when faced with ineffective airway clearance. The child’s respiratory system is highly affected by the disease, which leads to thick mucus production and consequently airway obstruction. Maintaining a respiratory rate and rhythm within the expected range is vital for ensuring adequate gas exchange and preventing hypoxia.

By focusing on this specific outcome criterion, the nurse addresses an immediate and significant concern related to the child's respiratory health. A normal respiratory rate and rhythm indicate effective ventilation and oxygenation, which are critical to the child’s overall wellbeing. Monitoring this parameter can help gauge the effectiveness of interventions aimed at improving airway clearance.

Engagement in age-related activities, absence of chills and fever, and the ability to tolerate a usual diet are also important aspects of care. However, they do not address the most acute issue at hand—the child's ability to maintain an effective airway and adequate respiratory function. Prioritizing outcomes that stabilize and improve respiratory function will have a more immediate impact on the child's health.
