Answer to Question 1

ANS: B
Otitis externa (OE) is inflammation of the ear canal and outer ear. Frequent causes include pseudomonas and fungal organisms. It is frequently associated with swimming as well as trauma. Acute otitis media (AOM) involves infection of the fluid in the middle ear space. The three bacterial organisms most often associated with AOM include streptococcal pneumonia, Haemophilus influenzae, and Moraxella catarrhalis. Frequently, viral organisms coexist with one of the preceding bacterial causes.
