In a patient, Weber test lateralizes to the right ear and Rinne test is negative in the right ear. What type of hearing loss is present?
Appeared in: NORCET 10 Mains
Explanation
- The patient has conductive hearing loss in the right ear.
- In the Weber test, sound lateralizing to the affected ear is a sign of conductive hearing loss. The external sounds are blocked, making the bone-conducted vibrations from the tuning fork more prominent in that ear.
- A negative Rinne test means that bone conduction (BC) is better than air conduction (AC). This is a hallmark of conductive hearing loss, as there is an obstruction in the outer or middle ear preventing sound from traveling efficiently through the air pathway.
- The combination of Weber lateralizing to the right and a negative Rinne in the right ear specifically localizes the conductive hearing loss to the right side.
Why Other Options Were Wrong
- Option B: For sensorineural hearing loss in the right ear, the Weber test would lateralize to the left (unaffected) ear, and the Rinne test would be positive (AC > BC) because the nerve is the problem, not the conduction pathway.
- Option C: If there were conductive hearing loss in the left ear, the Weber test would lateralize to the left ear.
- Option D: In a person with normal hearing, the Weber test would not lateralize (sound heard equally in both ears), and the Rinne test would be positive in both ears (AC > BC).

Clinical Relevance
- Nursing practice connection: Use the key finding related to Interpretation of Weber and Rinne hearing tests to guide bedside assessment, documentation, and the next nursing action.
- The Weber and Rinne tests are fundamental, low-cost, and quick bedside screening tools for nurses and doctors to differentiate between the two main types of hearing loss.
- Identifying the type of hearing loss is critical for determining the next steps in management. Conductive hearing loss is often treatable (e.g., removing impacted cerumen, treating otitis media), whereas sensorineural hearing loss is typically permanent and may require hearing aids.
- What if? If the Weber test lateralized to the right ear, but the Rinne test was positive in both ears, the diagnosis would be sensorineural hearing loss in the left ear. The sound lateralizes to the better-hearing right ear, and the AC > BC ratio remains normal in both ears.
How to Approach the Question
- First, analyze the result of the Weber test. Lateralization means the sound is louder in one ear. Note which ear.
- Recall the rules for Weber: It lateralizes to the affected ear in conductive hearing loss and to the unaffected ear in sensorineural hearing loss.
- Next, analyze the result of the Rinne test for the specified ear. A 'negative' result means bone conduction is better than air conduction (BC > AC).
- Recall the rules for Rinne: A negative test indicates conductive hearing loss. A positive test (AC > BC) is normal or seen in sensorineural loss.
- Combine the findings. Weber lateralizing to the right + negative Rinne on the right confirms a conductive problem on the right.
- Evaluate the options based on your conclusion and eliminate those that contradict the test results.
