A nurse assessing the results of a Rinne test sees the notation of BC > AC. How should the nurse translate this result?
Normal hearing
Cochlear defect
Conductive hearing loss
Sensorineural hearing loss
The Correct Answer is C
a) Normal hearing: In normal hearing, air conduction (AC) should be greater than bone conduction (BC), meaning BC > AC is not a normal finding.
b) Cochlear defect: A cochlear defect would result in sensorineural hearing loss, which would show a normal Rinne test (AC > BC).
c) Conductive hearing loss: BC > AC indicates conductive hearing loss, where sound transmission through the external or middle ear is impaired, allowing bone conduction to be heard more clearly than air conduction.
d) Sensorineural hearing loss: Sensorineural hearing loss typically shows a normal or positive Rinne test (AC > BC), as the issue lies with the inner ear or auditory nerve, not the conduction of sound.

Correct Answer is B
Explanation
a) Fever: Fever is not a common adverse effect of mannitol.
b) Fluid overload: Mannitol is an osmotic diuretic, and while it helps reduce fluid in the brain, it can sometimes lead to fluid retention and overload in other parts of the body.
c) Bradycardia: Bradycardia is not a typical adverse effect of mannitol.
d) Anaphylaxis: Although rare, anaphylaxis is a potential but not common adverse effect of mannitol. It is more likely to cause fluid and electrolyte disturbances.
Correct Answer is A
Explanation
a) A red, dull, thick, and immobile tympanic membrane: In acute otitis media, the tympanic membrane typically appears red, dull, thickened, and may be immobile due to fluid and infection in the middle ear.
b) A transparent and clear tympanic membrane: This would suggest a healthy, non-infected ear, which is not expected in acute otitis media.
c) A pink-colored tympanic membrane: This is not a typical finding in acute otitis media; a pink membrane is more characteristic of a healthy ear.
d) A pearly colored tympanic membrane: A pearly color is normal for the tympanic membrane, indicating a healthy ear with no infection.
