1. What is the cause of saddle numbness and urinary retention?
Correct Answer: Cauda equina syndrome
1. Cauda equina syndrome is a surgical emergency caused by compression of the nerve roots
below the conus medullaris.
2. Classic triad: saddle anesthesia, urinary retention/incontinence, and bilateral leg weakness or
areflexia.
3. Requires emergent MRI and surgical decompression to prevent permanent paralysis and
bladder dysfunction.
2. How does retinal detachment typically present?
Correct Answer: Sudden visual loss that is unilateral and painless
1. Retinal detachment often presents with sudden, painless monocular vision loss, often described
as a curtain or shadow over the visual field.
2. Patients may also report flashes of light (photopsia) or floaters.
3. Immediate ophthalmology referral is required as delayed treatment leads to permanent vision
loss.
3. Describe an obtunded patient.
Correct Answer: Patient opens eyes and looks at you but responds slowly and is somewhat confused.
Alertness and interest in environment are decreased.
1. Obtunded is a level of consciousness between lethargy and stupor.
2. Patients have decreased alertness, slow responses, confusion, and diminished interest in
surroundings.
3. This contrasts with lethargic (drowsy but arousable) and stuporous (arousable only with painful
stimuli).
, 4. Which cranial nerve controls lateral gaze?
Correct Answer: CN VI (Abducens)
1. CN VI innervates the lateral rectus muscle, which abducts the eye.
2. CN VI palsy presents with inability to abduct the affected eye (esotropia).
3. The mnemonic "LR6" helps recall lateral rectus = CN VI.
5. What information is included in Adult Illnesses section of health history?
Correct Answer: Medical illnesses (diabetes, hypertension, hepatitis, asthma, HIV), hospitalizations,
sexual history, surgical history (dates, indications, types), obstetric/gynecologic history, psychiatric
history (diagnoses, hospitalizations, treatments).
1. Past medical history includes acute and chronic conditions, hospitalizations, surgeries, and
psychiatric history.
2. This section establishes baseline health and identifies risk factors for current complaint.
6. What is included in the Present Illness section?
Correct Answer: Chronologic description of the problem including: location, quality, quantity/severity,
timing (onset/duration/frequency), setting, aggravating/relieving factors, associated manifestations. Also
includes medications, allergies, tobacco, alcohol, and drug use.
1. HPI uses the seven attributes of a symptom to fully characterize each problem.
2. This narrative guides differential diagnosis and diagnostic testing.
7. What does absence of red reflex indicate?
Correct Answer: Opacity of the lens (cataract) or vitreous; less commonly detached retina or
retinoblastoma in children.
1. Red reflex is caused by light reflecting off the retina.
2. Absent or asymmetric red reflex requires ophthalmology evaluation.
3. In children, leukocoria (white pupil) can indicate retinoblastoma, a life-threatening malignancy.
8. What are signs and symptoms of seasonal allergies?
Correct Answer: Itching, watery eyes, sneezing, ear congestion, postnasal drainage
1. Allergic rhinitis presents with pruritus, clear rhinorrhea, sneezing, and conjunctival injection.
2. Differentiated from infectious rhinitis by absence of fever and presence of itching.
9. How does optic neuritis present?
Correct Answer: Enlarged blind spot, vision loss in one eye, loss of color vision, hole in center of
vision (central scotoma), trouble seeing to the side, eye pain (especially with movement).
1. Optic neuritis is often associated with multiple sclerosis.
2. Pain with eye movement is a distinguishing feature from other causes of vision loss.
