, 1. PRIORITY NEUROLOGIC ASSESSMENT
Q1. What is the first priority when caring for a client with acute neurologic dysfunction?
Use an ABC approach: ensure airway patency, adequate breathing and oxygenation, and circulation. A neurologic injury
can rapidly compromise protective reflexes and ventilation.
Q2. What should be established during a baseline neurologic assessment?
Level of consciousness, orientation, speech, pupil size/reactivity, motor strength, sensation, facial symmetry, coordination
when appropriate, vital signs, and any focal deficits.
Q3. Why is trending neurologic findings important?
A single assessment provides a snapshot. Serial examinations reveal deterioration or improvement. A subtle change in
consciousness or pupil response can be clinically significant.
Q4. What is a focal neurologic deficit?
A localized abnormality such as unilateral weakness, facial droop, aphasia, visual-field loss, or a unilateral sensory change
that can help identify the area of neurologic dysfunction.
Exam trap
Do not focus on a dramatic but non-life-threatening finding while ignoring airway compromise, rapidly declining
consciousness, or new focal deficits.
2. GLASGOW COMA SCALE
Q5. What does the Glasgow Coma Scale assess?
It provides a standardized assessment of level of consciousness using eye opening, verbal response, and motor response.
Q6. What are the three GCS components?
Eye opening (E), verbal response (V), and motor response (M). The total score ranges from 3 to 15.
Q7. A client opens eyes to pain, uses incomprehensible sounds, and withdraws from pain. What is the score?
Eye = 2, verbal = 2, motor = 4. Total = 8.
Q8. Why is a declining GCS concerning?
A decrease can indicate worsening cerebral function and may signal increasing intracranial pressure, expanding
hemorrhage, edema, hypoxia, or another deterioration.
Memory aid
Think E-V-M: Eyes, Voice, Movement. Record the individual components when communicating a change, not only the total.
3. INCREASED INTRACRANIAL PRESSURE
Q9. What is intracranial pressure?
Pressure within the rigid cranial vault produced by brain tissue, cerebrospinal fluid, and intracranial blood.
Q10. What is the Monro-Kellie concept?
The skull contains relatively fixed total volume. If one intracranial component increases, compensation must occur through
reduction of another component; once compensatory mechanisms are exhausted, ICP can rise rapidly.
Q11. What early finding can occur with increased ICP?
Change in level of consciousness is particularly important. Headache, nausea/vomiting, pupillary changes, and other
neurologic alterations may occur.
