A 4-year-old is admitted to the ER and is being assessed by a nurse. What are the clinical findings of epiglottitis? (Select All that Apply.)

A. Stridor is a hallmark sign of upper airway obstruction and is commonly present in epiglottitis. B. A dry, barking cough is more characteristic of croup (laryngotracheobronchitis), not epiglottitis. C. Difficulty swallowing (dysphagia) occurs due to inflammation and swelling of the epiglottis. D. Drooling is a key symptom because the child is unable or unwilling to swallow secretions due to pain and obstruction. E. Hoarseness and difficulty speaking (muffled or "hot potato" voice) are common due to swelling near the vocal cords and larynx. F. Epiglottitis typically presents with a sudden high-grade fever, not a low-grade one.
