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 A
Explanation
a) "I will bend at my knees if I need to pick something up off of the floor." This statement shows an understanding of the importance of avoiding bending over at the waist post-surgery, which can increase intraocular pressure and disrupt the healing process.
b) "I can begin lying on my operative side 24 hours after my surgical procedure." Lying on the operative side should be avoided to prevent pressure on the healing eye.
c) "I will take a dose of aspirin if I have pain in the area of my eyebrow." Aspirin should generally be avoided after cataract surgery due to its anticoagulant effects, which may increase the risk of bleeding.
d) "I can pick up a sack of groceries that weighs 15 pounds." Lifting heavy objects is discouraged after cataract surgery to avoid putting pressure on the eye and affecting healing.
Correct Answer is C
Explanation
a) Leaving the bed in the highest position: This could create a fall risk for the visually impaired person, so it is not an appropriate intervention.
b) Leaving the radio on all the time to help the patient know the time of day: While this may provide some information, it is not the most effective approach for supporting a visually impaired client.
c) Announcing your presence when you enter and leave the room: This is an essential intervention to orient a visually impaired person and help them understand the environment.
d) Keeping the door closed: This could pose a safety risk by limiting the client’s ability to orient to the surroundings. It is generally better to keep doors open for better access and awareness.
