In the case of a suspected epiglottitis in a 3-year-old child, the nurse should prioritize the following actions:
1. **Prepare to assist with intubation:** Epiglottitis is a serious condition where the epiglottis, a flap of tissue that covers the trachea during swallowing to prevent food from entering the airway, becomes inflamed and can obstruct the airway. Intubation may be necessary to secure the child's airway and ensure adequate breathing.
2. **Obtain a throat culture:** A throat culture can help confirm the presence of bacteria causing the epiglottitis, which can guide appropriate treatment with antibiotics.
It is crucial to act swiftly and efficiently in suspected cases of epiglottitis to ensure the child's airway is protected and appropriate treatment is initiated promptly. The nurse should closely monitor the child's respiratory status and be prepared to take further actions as necessary in consultation with a healthcare provider.
