QUESTION 1
What does the WHO International Classification of Functioning,
Disability and Health (ICF) model emphasize in rehabilitation?
A. Sole focus on disease diagnosis and pathology
B. An interactive framework addressing body functions and structures,
activity, and participation within environmental and personal contexts
C. Complete medical cure of chronic genetic anomalies
D. Elimination of all social interaction for patients
Correct Answer: B. An interactive framework addressing body functions
and structures, activity, and participation within environmental and
personal contexts
Detailed Rationale: The ICF model shifts focus from biological disease
to a biopsychosocial framework measuring how a health condition
impacts body structures, daily activities, and societal participation.
QUESTION 2
Which clinical feature characterizes Wernicke's (fluent) aphasia
resulting from damage to the left temporal lobe?
,A. Impaired auditory comprehension, fluent speech with normal
grammatical structure, but containing paraphasias (word substitutions)
and meaningless jargon
B. Complete mutism with total paralysis of the tongue
C. Halting, telegraphic, non-fluent speech with intact comprehension
D. Isolated loss of facial recognition
Correct Answer: A. Impaired auditory comprehension, fluent speech
with normal grammatical structure, but containing paraphasias (word
substitutions) and meaningless jargon
Detailed Rationale: Damage to Wernicke's area affects language
comprehension. Speech flows effortlessly with normal rhythm and
intonation, but the content makes little sense due to word substitution
errors.
QUESTION 3
What neurological pattern defines Brown-Séquard syndrome following
a spinal cord hemisection injury?
A. Ipsilateral (same side) motor paralysis and loss of
proprioception/vibration, combined with contralateral (opposite side)
loss of pain and temperature sensation below the lesion
B. Complete bilateral paralysis and loss of all sensation from head to toe
C. Bilateral loss of pain and temperature with preserved motor function
D. Loss of motor function exclusively in upper extremities
,Correct Answer: A. Ipsilateral (same side) motor paralysis and loss of
proprioception/vibration, combined with contralateral (opposite side)
loss of pain and temperature sensation below the lesion
Detailed Rationale: Brown-Séquard syndrome involves hemisection of
the cord, disrupting the corticospinal tracts and dorsal columns on the
same side (ipsilateral motor/proprioception loss) and the spinothalamic
tract on the opposite side (contralateral pain/temperature loss).
QUESTION 4
What is the characteristic clinical presentation of Anterior Cord
Syndrome?
A. Loss of motor function, pain, and temperature sensation below the
injury, with preservation of light touch, proprioception, and vibration
sense
B. Loss of vibration sense only with normal motor function
C. Permanent recovery of total function within 2 hours
D. Preservation of lower extremity motor power with total arm paralysis
Correct Answer: A. Loss of motor function, pain, and temperature
sensation below the injury, with preservation of light touch,
proprioception, and vibration sense
Detailed Rationale: Anterior cord syndrome typically results from
compression or infarction of the anterior spinal artery, destroying the
corticospinal and spinothalamic tracts while sparing the posterior
columns.
QUESTION 5
, According to the Rancho Los Amigos Scale of Cognitive Functioning,
what behavior defines Level V (Confused-Inappropriate)?
A. Appears alert and responds to simple commands fairly consistently,
but exhibits non-purposeful behavior, highly distractible attention, and
inappropriate verbalization when structured tasks are complex
B. Deeply comatose with zero responsiveness
C. Fully oriented to all times and places with flawless executive
organization
D. Extremely aggressive, combative, and violent
Correct Answer: A. Appears alert and responds to simple commands
fairly consistently, but exhibits non-purposeful behavior, highly
distractible attention, and inappropriate verbalization when structured
tasks are complex
Detailed Rationale: Rancho Level V patients can follow simple
directions consistently, but their responses become inappropriate and
random when faced with unstructured or complex environmental
demands due to severe memory and attention deficits.
QUESTION 6
What is a critical nursing instruction for a patient prescribed oral
bisphosphonates (e.g., alendronate) for osteoporosis management?
A. Take the medication first thing in the morning with a full glass of
plain water on an empty stomach, and remain upright (sitting or
standing) for at least 30 minutes without lying down.
B. Crush the tablet and mix it into evening dessert.
