Sample itemWhat finding is typical of a perforated tympanic membrane?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
C. Visible membrane defect
Otoscopy may directly show a break or hole in the tympanic membrane when it is perforated by infection, trauma, or pressure change.
Option by option
A. Fixed dilated pupil
A fixed dilated pupil is an ocular or neurologic sign.
B. Nasal polyp
Nasal polyps arise from nasal mucosa, not the eardrum.
C. Visible membrane defect (correct)
Correct: a membrane defect is the direct otoscopic finding.
D. Laryngeal stridor
Stridor reflects upper-airway narrowing, not tympanic injury.
