He has been attending a daycare center for the past 5 months. His temperature is 38.4C 101.1F and pulse is 144min. Otoscopic examination in this child is most likely to show which of the following?? A: Bulging erythematous tympanic membrane, B: Retracted opacified tympanic membrane, C: Erythematous external auditory canal, D: Vesicles in the ear canal, E: Brown mass within the ear canal,  <response>: This is a clinical vignette about a 9-month-old boy with fever, irritability, crying, and ear tugging, particularly on the right side. He also had a recent history of a runny nose. The key findings are fever, ear tugging on one side, and irritability in an infant. This clinical presentation is most consistent with acute otitis media middle ear infection. The question asks about the likely otoscopic exam findings. Choices include findings consistent with otitis media bulging, erythematous tympanic membrane, otitis media with effusion retracted, opacified tympanic membrane, external otitis erythematous ear canal, herpes zoster oticus vesicles in the ear canal, and a foreign body in the ear canal. Given the clinical presentation of acute otitis media, the most likely otoscopic finding would be a bulging, erythematous tympanic membrane.A: Bulging erythematous tympanic membrane
