<prompt> When evaluating for possible otitis media, which of the following is of the least diagnostic value?History of a new onset of ear pulling staing several days after URIPresence of the light reflexTranslucency of the tympanic membrane TMMobility in response to pneumatoscopy  <response>: The light reflex can often be visualized in an abnormal ear. Gauging, decreased translucency of the TM and evaluating for the presence of a fluid level behind the TM requires experience, but these are good indicators of infection when detected. Mobility in response to pneumatoscopy is also quite sensitive in practiced hands. New-onset ear pulling after URI is frequently associated with otitis media.
