Following a Call in Which You Treated a Pediatric Patient

Following a call in which you treated a pediatric patient suffering from croup, a new EMT who is in orientation asks you how you can differentiate croup from epiglottitis. Which one of the following responses would be most appropriate?

A) "The swelling associated with epiglottitis typically decreases with exposure to cool air; the swelling with croup does not."
B) "Epiglottitis is accompanied by a cough; croup is not associated with a cough."
C) "Croup is typically associated with wheezing; epiglottitis is typically associated with crackles in the lungs."
D) "The child with epiglottitis typically drools; the child with croup rarely, if ever, drools."
