ear for a few years. The patient's mother had had the same condition when she was in her
40s, and she underwent a successful operation. Assessment is performed using the Weber
and Rinne tests.
Question
What physical exam finding is expected?

Bone conduction of the affected side is greater than air conduction. Bone conduction
of the affected side is equal to air conduction.
Air conduction of the affected side is greater than bone conduction.
Sound lateralizes to the unaffected ear.
Bone conduction of the unaffected ear is greater than air conduction.: Bone conduction of
the affected side is greater than air conduction
4. A 41-year-old woman presents to the local emergency department with a 14-day
history of nasal drainage, congestion, fever, and cheek pain. She was started on
amoxicillin/clavulanate initially, but she was switched to levofloxacin 7 days ago due to no

the right ear. Weber and Rinne tests are performed.
Question
What results are expected?

A Weber—sound is heard louder in right ear; Rinne—bone conduction exceeds air
conduction in right ear
B Weber—sound is heard louder in left ear; Rinne—bone conduction exceeds air
conduction in right ear
C Weber—sound is heard louder in right ear; Rinne—air conduction exceeds bone
conduction in right ear
D Weber—sound is heard louder in left ear; Rinne—air conduction exceeds air conduction
in right ear
E Weber—sound is equal in both ears; Rinne—bone conduction greater than




, EENT Exam Master

air conduction in right ear: C Weber—sound is heard louder in right ear; Rinne—bone
conduction exceeds air conduction in right ear
8. A 67-year-old woman presents; according to her, her husband says she never listens
to anything he says. The patient states that occasionally she has to ask people to repeat
themselves when sitting to her right. She denies any dizziness, headaches, or visual
disturbances. Her current medication is furosemide. On physical examination, the Weber
test reveals lateralization to the left ear. On the left ear, air conduction lasted for 15 seconds
and bone conduction lasted 10 seconds. On the right ear, air conduction lasted for 22
seconds and bone conduction lasted 10 seconds.

Question
What is the most likely cause of this hearing loss?

Cerumen impaction
Otosclerosis
Ototoxicity
Ménière's disease
Middle ear effusion: Ototoxicity
9. A 35-year-old woman presents with a painful swelling of her left eyelid. On physical
