Which child should the practical nurse (PN) assess first?

The 18-month-old child who has cystic fibrosis and is wheezing should be assessed first because this situation indicates a potential respiratory emergency. Cystic fibrosis is a genetic disorder that affects the lungs and can lead to severe respiratory complications. Wheezing may signify bronchial obstruction or increased airway resistance, which can escalate quickly and be dangerous for a child with a compromised respiratory system.

In addition, the age of the child adds to the urgency, as infants and toddlers are particularly vulnerable to respiratory distress. In this case, the symptoms of wheezing in a child with cystic fibrosis should be prioritized for assessment to ensure timely intervention, which is crucial in preventing further complications or deterioration of the child’s condition.

The other options, while they do indicate health concerns, do not present the same immediate level of risk associated with respiratory distress in a child with cystic fibrosis, making the wheezing child the priority for assessment.
