Which respiratory infection should the nurse monitor the toddler age client for based on structural difference during thus stage of development?

Since there is no options, I'm going to take a shot in the dark. I'm thinking that the answer would be epiglottitis, simply because any movement or excess probing into the child's airway could cause it to swell up and completely occlude the airway. Then, a surgical airway would have to be placed.

That's my best guess without further options.
