MSRA-0558
A 7-year-old girl comes to the emergency department with a 2-day history of right-sided otalgia and otorrhoea. Her mother suspects a middle ear infection as she has had them before. During the examination, she is found to be running a fever and has tenderness behind her right ear. The affected ear appears more prominent than the other, and otoscopy reveals a red tympanic membrane with a visible tear and pus discharge. What is the typical initial treatment for this probable diagnosis?
