A nurse is assessing a client for conductive hearing loss. When using the Rinne test, which of the following results should the nurse identify as an indication that the client has conductive hearing loss of the left ear?
Sound is lateralizing to the right ear.
Sound is lateralizing to the left ear.
Air conduction is greater than bone conduction in the left ear.
Air conduction is less than bone conduction in the left ear.
The Correct Answer is D
Choice A rationale
Sound lateralizing to the right ear during the Rinne test does not indicate conductive hearing loss in the left ear. This result suggests that the right ear may have better hearing or that there is an issue with the left ear, but it does not specifically diagnose conductive hearing loss.
Choice B rationale
Sound lateralizing to the left ear during the Rinne test indicates that the left ear is perceiving the sound better, which could be due to conductive hearing loss in the left ear. However, this option does not provide a definitive result for conductive hearing loss.
Choice C rationale
Air conduction being greater than bone conduction in the left ear is a normal finding and does not indicate conductive hearing loss. In conductive hearing loss, bone conduction is typically better than air conduction.
Choice D rationale
Air conduction being less than bone conduction in the left ear is indicative of conductive hearing loss. This result means that the sound is being conducted through the bones of the skull more effectively than through the air, which is a hallmark of conductive hearing loss.

Correct Answer is D
Explanation
Choice A rationale
This statement is incorrect. While the tubes are designed to allow air to enter the middle ear and prevent fluid buildup, water can still enter through the tubes and potentially cause infections or other complications. Therefore, it is important to take precautions to keep water out of the ears, especially during activities like swimming or bathing.
Choice B rationale
This statement is incorrect. Tympanostomy tubes are not designed to be removed every night. They are small tubes inserted into the eardrum to allow air to enter the middle ear and prevent fluid buildup. They remain in place until they naturally fall out on their own, which typically happens within 6 to 12 months.
Choice C rationale
This statement is incorrect. The tubes do not need to be replaced every 2 years. Tympanostomy tubes usually fall out on their own within 6 to 12 months. If they do not fall out naturally, a healthcare provider may need to remove them. However, routine replacement every 2 years is not necessary.
Choice D rationale
This statement is correct. Tympanostomy tubes are designed to fall out on their own, usually within 6 to 12 months after insertion. This natural process allows the eardrum to heal without the need for additional surgical intervention.
Correct Answer is C
Explanation
Choice A rationale
Pitting edema of the hands and fingers is not a typical finding in clients with systemic lupus erythematosus (SLE). Edema can occur in SLE, but it is more commonly associated with renal involvement and not specifically pitting edema of the hands and fingers.
Choice B rationale
Subcutaneous nodules on the ulnar side of the arm are more commonly associated with rheumatoid arthritis rather than SLE. SLE does not typically present with subcutaneous nodules.
Choice C rationale
A dry, red rash across the bridge of the nose and on the cheeks, known as a “butterfly rash,” is a classic sign of SLE. This rash is caused by inflammation of the small blood vessels in the skin and is often exacerbated by sun exposure.
Choice D rationale
A grey-colored, non-purpuric papular rash is not characteristic of SLE. The typical rash in SLE is the butterfly rash, which is dry, red, and raised.
