SECTION ONE: QUESTIONS 1–100
Question 1.
A 3-year-old child presents with fever, ear pain, and a bulging, erythematous tympanic
membrane. Which finding most strongly supports a diagnosis of acute otitis media?
A. Retracted tympanic membrane with air-fluid level
B. Bulging tympanic membrane with decreased mobility
C. Mild external canal erythema
D. Clear middle-ear effusion without inflammation
Correct Answer: B. Bulging tympanic membrane with decreased mobility
, Explanation: A bulging tympanic membrane with impaired mobility is a classic finding of
acute otitis media. Retraction is more consistent with eustachian tube dysfunction, while
external canal inflammation suggests otitis externa.
Question 2.
Which organism is a common bacterial cause of acute otitis media in children?
A. Streptococcus pneumoniae
B. Candida albicans
C. Pseudomonas aeruginosa
D. Mycoplasma pneumoniae
Correct Answer: A. Streptococcus pneumoniae
Explanation: Streptococcus pneumoniae is among the most common bacterial pathogens
causing acute otitis media. Haemophilus influenzae and Moraxella catarrhalis are also
important pathogens.
Question 3.
A child has acute otitis media and received amoxicillin during the previous month. Which
antibiotic strategy is generally appropriate when bacterial treatment is indicated and recent
amoxicillin exposure raises concern for resistant organisms?
A. Repeat the same amoxicillin regimen indefinitely
B. Use amoxicillin-clavulanate when clinically appropriate
C. Use topical ciprofloxacin ear drops alone
D. Use an antifungal medication
Correct Answer: B. Use amoxicillin-clavulanate when clinically appropriate
Explanation: Recent amoxicillin exposure is a reason to consider broader beta-lactam
coverage, commonly with amoxicillin-clavulanate, when antibiotic treatment is indicated.
Question 4.
Which assessment finding is most characteristic of otitis externa?
A. Bulging tympanic membrane
B. Pain with movement of the tragus
C. Bilateral middle-ear effusion
D. Painless hearing loss
Correct Answer: B. Pain with movement of the tragus
Explanation: Otitis externa involves inflammation of the external auditory canal. Pain elicited
by manipulation of the tragus or pinna is highly characteristic.
