Final answer:
In a patient with otitis media and serious otitis, a nurse practitioner using a tympanogram will typically note a flat or straight line, indicating the presence of fluid in the middle ear. b. Peaked shape
Step-by-step explanation:
A nurse practitioner assessing a patient for otitis media with effusion (OME) or serious otitis will use a tympanogram, which is a test that can help detect the presence of fluid in the middle ear, a common issue in these conditions. When the eustachian tubes become blocked, fluid can build up in the middle ear, creating an environment for infections and leading to OME. In a patient experiencing these conditions, the tympanogram will most commonly display a flat line or straight line, indicating that there is fluid present behind the tympanic membrane which restricts its movement. This differs from the normal peaked shape of a healthy ear's tympanogram, which shows that the tympanic membrane is moving properly. In a patient with otitis media or serous otitis, a tympanogram—a graphic representation of the relationship between air pressure in the ear canal and the movement of the eardrum—may show a peaked shape. This peaked or sharp spike indicates reduced compliance of the middle ear, which can be associated with fluid accumulation or other abnormalities in the middle ear. The other options (a, c, and d) do not typically correspond to the tympanogram findings in cases of otitis media or serous otitis.
