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) Headache: While headaches can occur with eye strain or other eye conditions, they are not a hallmark symptom of open-angle glaucoma.
b) Loss of peripheral vision: Open-angle glaucoma is characterized by gradual loss of peripheral vision, often referred to as "tunnel vision," due to increased intraocular pressure affecting the optic nerve.
c) Discomfort in the eyes: Open-angle glaucoma typically has no early symptoms, and discomfort is not usually a prominent feature unless the disease progresses.
d) Halos around lights: Halos around lights are more commonly associated with acute angle-closure glaucoma, where there is a sudden rise in intraocular pressure, not open-angle glaucoma.
Correct Answer is D
Explanation
a) Mineralocorticoids: These are not used for allergic rhinitis. They primarily regulate sodium and potassium balance in the body.
b) Cortisol: Cortisol is a hormone, not a medication prescribed specifically for rhinitis.
c) Leukotrienes: These are used for allergic rhinitis treatment when antihistamines and sympathomimetics are ineffective. Leukotriene receptor antagonists help reduce inflammation.
d) Corticosteroids: Corticosteroids are commonly prescribed for allergic rhinitis, especially for persistent symptoms that do not respond to other medications.
