QUESTION 1
What is a critical precaution that must be implemented for children
born with myelomeningocele (spina bifida) due to their high lifetime
exposure risk?
A. Strict avoidance of dairy products
B. Strict latex-free environment and precautions
C. Permanent restriction from all educational settings
D. Mandatory daily systemic antibiotic prophylaxis
Correct Answer: B. Strict latex-free environment and precautions
Detailed Rationale: Children with myelomeningocele undergo
numerous surgeries and catheterizations early in life, resulting in a high
incidence of latex sensitization and life-threatening latex allergies,
requiring a strict latex-free environment.
QUESTION 2
Which nerve is most commonly compressed at the wrist, leading to
carpal tunnel syndrome in patients who rely heavily on manual
wheelchair propulsion?
A. Radial nerve
B. Ulnar nerve
,C. Median nerve
D. Musculocutaneous nerve
Correct Answer: C. Median nerve
Detailed Rationale: Repetitive wrist extension and high-pressure
weight-bearing during wheelchair propulsion place chronic stress on the
carpal tunnel, compressing the median nerve and causing paresthesia,
pain, and eventual motor weakness in the hand.
QUESTION 3
What clinical pattern characterizes Central Cord Syndrome following a
hyperextension injury of the cervical spine?
A. Complete loss of all motor and sensory function below the lesion
level
B. Greater motor impairment in the upper extremities than in the lower
extremities, with variable sensory retention
C. Paralysis of only one side of the body with preserved sensation on
the opposite side
D. Isolated loss of bowel and bladder control with completely normal
limb strength
Correct Answer: B. Greater motor impairment in the upper extremities
than in the lower extremities, with variable sensory retention
Detailed Rationale: Central cord syndrome damages the central portion
of the cervical spinal cord, where nerve fibers controlling the arms are
anatomically positioned more medially than those controlling the legs,
resulting in greater arm weakness compared to legs.
,QUESTION 4
Which communication deficit is characteristic of Wernicke's (receptive)
aphasia resulting from a left temporal lobe stroke?
A. Slow, halting speech with preserved language comprehension
B. Fluent, rapid speech that lacks meaningful content, accompanied by
severe impairment in understanding spoken and written language
C. Complete inability to produce any vocal sounds while fully
understanding written text
D. Inability to recognize familiar faces while speech remains entirely
unaffected
Correct Answer: B. Fluent, rapid speech that lacks meaningful content,
accompanied by severe impairment in understanding spoken and
written language
Detailed Rationale: Wernicke's aphasia involves damage to the
posterior superior temporal gyrus, leading to fluent articulation that
lacks sense ("word salad") and profound deficits in comprehending
communication.
QUESTION 5
What three behavioral categories are evaluated when scoring a patient
using the Glasgow Coma Scale (GCS)?
A. Temperature, blood pressure, and heart rate
B. Eye opening response, verbal response, and motor response
C. Cranial nerve reflexes, deep tendon reflexes, and muscle tone
D. Memory, attention span, and emotional affect
, Correct Answer: B. Eye opening response, verbal response, and motor
response
Detailed Rationale: The Glasgow Coma Scale assesses level of
consciousness based on eye-opening, verbal responsiveness, and motor
performance, providing a standardized baseline for acute and
rehabilitative neurological monitoring.
QUESTION 6
What common systemic side effect should a rehabilitation nurse
monitor for when a patient is initiated on oral baclofen for spasticity?
A. Severe hypertension and tachycardia
B. Drowsiness, fatigue, dizziness, and muscle weakness
C. Hyperactive reflexes and insomnia
D. Sudden visual hallucinations
Correct Answer: B. Drowsiness, fatigue, dizziness, and muscle weakness
Detailed Rationale: Oral baclofen acts on the central nervous system to
suppress spasticity, frequently causing systemic side effects like
sedation, lethargy, dizziness, and generalized weakness.
QUESTION 7
What clinical presentation defines Brown-Séquard Syndrome resulting
from a hemisection of the spinal cord?
A. Ipsilateral motor paralysis and loss of proprioception/vibration below
the lesion, combined with contralateral loss of pain and temperature
sensation
B. Complete bilateral paralysis with preserved deep tendon reflexes
