Answer to Question 1
ANS: A, C, D, E
The proximity of the sinus to the tooth roots often results in tooth pain when the sinus is infected. The maxillary and ethmoid sinuses are most often involved in childhood sinusitis. Therefore the signs and symptoms of sinusitis in children are different from those in adults, depending on the age of the child and which sinus is fully developed. An acute sinusitis is suspected when an upper respiratory infection lasts longer than 10 days, with a daytime cough. Halitosis is often present. Untreated sinusitis can lead to periorbital cellulitis. Severe wheezing is not indicative of sinusitis.

The onset of epiglottitis is abrupt, and the child presents with classic symptoms. The child insists on sitting up, leans forward with the mouth open, and drools saliva because of the difficulty in swallowing. The child appears wide-eyed, anxious, and restless, and he or she may emit a froglike croaking sound on inspiration. Cough is absent. Inspection of the throat shows an enlarged, reddened edematous epiglottis much like a beefy-red thumb. However, the examining tongue blade may trigger a laryngospasm and result in sudden respiratory arrest.
