Which of the following is NOT considered an objective finding in patients who have a case of suppurative otitis media?

Visualized mobility of the tympanic membrane (TM) as measured by tympanogram is not considered an objective finding in the context of a physical examination. This assessment is typically done using instrumental measurements, which provide objective data regarding the status of the middle ear.

In contrast, the other options represent observable characteristics that can be assessed during a physical examination. Erythema of the TM indicates inflammation and is visible upon examination. Displacement of the light reflex is also an observable finding that can indicate changes in the TM’s position or shape, usually a result of fluid buildup or infections like suppurative otitis media. Bulging of the TM is another key finding associated with otitis media, as it reflects pressure changes in the middle ear.

These observations help healthcare providers assess the status of the TM and make clinical decisions, unlike tympanometric measurements that rely on instruments to interpret TM mobility.
