Final answer:
The nurse should monitor for stridor in a client with epiglottitis in the ED.
Step-by-step explanation:
The nurse should monitor for stridor in a client with epiglottitis in the ED. Epiglottitis is a serious condition where the epiglottis becomes inflamed and can cause obstruction of the airway. Stridor is a high-pitched, noisy breathing sound that occurs when there is narrowing or obstruction of the upper airway. It is an important sign of respiratory distress and requires immediate attention.
