When planning care for a 6-year-old child with cystic fibrosis, which nursing intervention should be prioritized?

The clinical management of cystic fibrosis requires addressing multisystem impairments. This scenario focuses on the prioritization of nursing interventions based on the urgency of physiological needs. Knowledge of airway clearance techniques, enzyme replacement, and preventive care is necessary to identify the most critical action. Choice A rationale Nutrition is vital as the normal range for BMI should be maintained above the 50th percentile. Malabsorption occurs due to mucus blocking ducts, but nutritional counseling is a long-term goal rather than an immediate physiological priority. Choice B rationale Maintaining airway patency is the primary concern in cystic fibrosis due to viscous secretions. Chest physiotherapy facilitates mucus mobilization and prevents respiratory failure. Airway management always takes precedence over other interventions in the acute care setting. Choice C rationale Pancreatic enzymes are required to manage exocrine insufficiency and promote absorption of fats. While necessary for growth, this intervention follows airway stabilization. Lack of enzymes leads to steatorrhea but is not immediately life-threatening like airway obstruction. Choice D rationale Prevention of respiratory infections is important, as influenza can cause severe exacerbations. However, immunization is a secondary prevention strategy. It does not address the immediate mechanical need to clear obstructive mucus from the pulmonary system.
