PRACTICE QUESTIONS ON MENIERE'S DISEASE, VERTIGO,
OTITIS MEDIA, CONJUNCTIVITIS, GLAUCOMA, RETINAL
DETACHMENT, HEADACHES, SCHIZOPHRENIA, AND
THYROID-RELATED DISORDERS (EXOPHTHALMOS, PRETIBIAL
MYXEDEMA, GOITER) WITH COMPLETE SOLUTIONS AND
RATIONALES
1. What is the primary cause of Meniere's disease?
A. Viral infection of the cochlea
B. Fluid changes in the inner ear, trauma, infection
C. Autoimmune destruction of hair cells
D. Excessive cerumen impaction
Correct Answer: B
Rationale: Meniere's disease is associated with fluid changes in the
inner ear, as well as trauma and infection, leading to episodes of vertigo
and hearing loss.
2. Which of the following is a recognized cause of vertigo?
A. Dehydration, motion sickness, ear infection, head trauma, benign
paroxysmal positional vertigo
B. Hypertension
C. Hyperthyroidism
D. Anemia
Correct Answer: A
,Rationale: Vertigo can stem from various conditions including
dehydration, motion sickness, ear infections, head trauma, and benign
paroxysmal positional vertigo.
3. What diagnostic test is commonly used for vertigo?
A. Particle repositioning
B. MRI of the brain
C. Audiometry
D. CT scan of the temporal bone
Correct Answer: A
Rationale: Particle repositioning maneuvers (e.g., Epley maneuver) are
used both diagnostically and therapeutically for benign paroxysmal
positional vertigo.
4. Which of the following is a sign or symptom of vertigo?
A. Chest pain
B. Dizzy, unbalanced, lightheaded
C. Numbness in extremities
D. Blurred vision only
Correct Answer: B
Rationale: Vertigo typically presents with dizziness, a feeling of being
unbalanced, and lightheadedness.
5. What is a common cause of otitis media?
A. Bacterial pneumonia
B. URV (upper respiratory virus), mucous stuck in ear
C. Fungal infection of the external canal
D. Allergic rhinitis only
Correct Answer: B
,Rationale: Otitis media often follows an upper respiratory virus that
causes Eustachian tube dysfunction and mucous accumulation.
6. Which of the following are signs and symptoms of otitis media?
A. Ear pain, children→ increased crying, poor sleep, fever, cough
B. Ringing in the ears only
C. Clear drainage from the ear
D. Facial paralysis
Correct Answer: A
Rationale: Otitis media commonly causes ear pain; in children, it leads
to increased crying, poor sleep, fever, and cough.
7. What are the signs and symptoms of conjunctivitis?
A. Yellow sclera
B. Pink eye, increased tears, eyes stuck in the morning
C. Double vision
D. Severe eye pain
Correct Answer: B
Rationale: Conjunctivitis ("pink eye") presents with redness, excessive
tearing, and crusting or sticking of the eyes upon waking.
8. Which of the following is a sign or symptom of glaucoma?
A. Cloudy eyes
B. Red eyes
C. Itchy eyes
D. Photophobia
Correct Answer: A
Rationale: Glaucoma may cause cloudy appearance of the eyes due to
corneal edema from increased intraocular pressure.
, 9. What are risk factors for glaucoma?
A. Low blood pressure and young age
B. Increased pressure in the eye, family history, high BP
C. Diabetes and obesity
D. Smoking and alcohol use
Correct Answer: B
Rationale: Risk factors for glaucoma include elevated intraocular
pressure, positive family history, and hypertension.
10. What test is used for diagnosing glaucoma?
A. Eye puff test (tonometry)
B. Slit-lamp examination
C. Visual acuity test
D. Fundoscopic exam
Correct Answer: A
Rationale: The "eye puff test" or tonometry measures intraocular
pressure, which is elevated in glaucoma.
11. What is a cause of retinal detachment?
A. Trauma to the eye, being short-sighted (myopic)
B. Excessive eye rubbing
C. High blood sugar
D. Prolonged screen time
Correct Answer: A
Rationale: Retinal detachment can result from ocular trauma or myopia,
which predisposes the retina to tears.
12. What is a sign or symptom of retinal detachment?
A. Flashing lights only
B. Part of the retina that is detached will be black (visual field defect)
