In assessing a 2-year-old boy with croup, the practical nurse (PN) finds that he has become increasingly irritable and has developed tachypnea and resting- Which intervention is best for the PN to implement?

Croup is a viral infection that affects the upper airways, causing inflammation and narrowing of the air passages. In severe cases, it can lead to respiratory distress, including increased work of breathing and decreased oxygen saturation levels. Monitoring the child's oxygen saturation level using a pulse oximeter is an essential intervention to assess the severity of respiratory distress and the need for further interventions. A. Encouraging the child to drink cool, clear liquids can help soothe the throat and prevent dehydration. B. Instructing the mother to play with the child for stimulation and distraction can help provide comfort and alleviate anxiety. D. Administering acetaminophen as needed (PRN) can help reduce fever and discomfort. However, none of these interventions directly address the potential respiratory distress and the need for oxygenation assessment.
