Q1 QUESTION 1 OF 72
Cause of saddle numbness and urinary retention
RESPONSE
Cauda equina syndrome
RATIONALE
Compression of the nerve roots in the lumbar sacral spine, specifically the cauda equina, impairs
nerve signals to the bladder and perineal region. This leads to the characteristic symptoms of
saddle anesthesia and urinary retention. This neurological emergency requires prompt diagnosis
and management to prevent permanent deficits.
Q2 QUESTION 2 OF 72
Presentation of retinal detachment
RESPONSE
If sudden visual loss is unilateral and painless,
RATIONALE
Sudden, unilateral, and painless visual loss is a hallmark symptom of retinal detachment. This
presentation suggests a disruption in the photoreceptor layers' connection to the retinal pigment
epithelium, leading to impaired vision without accompanying ocular pain. Prompt evaluation is
indicated to prevent permanent vision impairment.
Q3 QUESTION 3 OF 72
Cranial nerve for lateral gaze
RESPONSE
CN6: Abducens
Page 2
, RATIONALE
The abducens nerve, or CN VI, innervates the lateral rectus muscle of the eye. Contraction of this
muscle is responsible for outward movement of the eyeball, which is lateral gaze. Therefore,
dysfunction of CN VI directly impairs the ability to perform lateral gaze.
Q4 QUESTION 4 OF 72
Absence of red reflex
RESPONSE
an opacity of the lens (cataract) or, possibly, the vitreous (or even an artificial eye). Less
commonly, a detached retina or, in children, a retinoblastoma may obscure this reflex.
RATIONALE
The red reflex is the reflection of light off the retina. Its absence indicates an obstruction within the
optical pathway. This obstruction is most commonly a lens opacity like a cataract, or less
frequently, issues in the vitreous, retina, or a retinoblastoma in pediatric patients.
Q5 QUESTION 5 OF 72
Presentation of optic neuritis
RESPONSE
Enlarged blind spot, vision loss in 1 eye, loss of color vision, hole in center of vision, trouble
seeing to the side, eye pain
RATIONALE
Optic neuritis involves inflammation of the optic nerve, leading to characteristic visual field defects
and reduced visual acuity. This inflammation disrupts normal signal transmission, causing
symptoms such as unilateral vision loss, impaired color perception, and central or peripheral visual
field deficits. Pain with eye movement is also common due to nerve inflammation.
