Answer
CERTIFICATION EXAMINATION INSTRUCTIONS
▸ Select the single best answer for each question based on the official NIHSS training criteria.
▸ Questions cover all 15 NIHSS items: scoring methodology, administration techniques, clinical interpretation, and the
significance of the NIHSS as an impairment measurement tool.
▸ Distinguish carefully between scoring levels: Level of Consciousness (1a–1c), Best Gaze, Visual Fields, Facial Palsy, Motor
Arms/Legs, Limb Ataxia, Sensory, Best Language, Dysarthria, and Extinction/Inattention.
▸ Correct answers and detailed rationales appear below each question for comprehensive review.
▸ All content is derived from the official NIH Stroke Scale Training and Certification program.
SECTION I — NIHSS ADMINISTRATION, SCORING & CLINICAL 15
INTERPRETATION Questions
1. When administering the NIH Stroke Scale, what is the most important principle regarding the patient's responses?
A. Coach the patient to improve their performance for a more accurate assessment
B. Rate what the patient actually does — use the patient's FIRST response and avoid coaching
C. Repeat each test three times and average the scores
D. Score based on the patient's pre-stroke baseline abilities
CORRECT ANSWER B — Rate what the patient actually does, using their first response, and avoid coaching. Score only
what the patient demonstrates, not what you believe they can do.
RATIONALE Core NIHSS principles: (1) Administer items in exact order; (2) Avoid coaching the patient; (3) Accept the
patient's FIRST effort — do not go back and change scores; (4) Score only what the patient does, not what you
think they can do; (5) Be consistent across all assessments. The NIHSS measures impairment at a specific
moment, not potential ability. Coaching invalidates the score.
, 2. Is the NIH Stroke Scale a measure of disability?
A. Yes — it measures the patient's ability to perform activities of daily living
B. No — it is a measuring tool of IMPAIRMENTS, not disability
C. Yes — it measures both impairment and disability simultaneously
D. It measures only cognitive function
CORRECT ANSWER B — No. The NIHSS is a measure of IMPAIRMENTS (neurological deficits), not disability (functional
limitations in activities).
RATIONALE The NIHSS quantifies neurological impairment — specific deficits in consciousness, language, motor function,
sensation, and visual fields caused by stroke. Disability measures (such as the Modified Rankin Scale/mRS)
assess functional outcomes — walking, eating, dressing. The NIHSS is a prognostic tool that helps predict
outcomes but does not directly measure disability.
3. What is the significance of the NIH Stroke Scale in clinical practice?
A. It is only used for research purposes and has no clinical utility
B. It is a necessary prognostic tool for discerning deficits, provides a common language for interdisciplinary
communication, and helps determine stroke severity and treatment decisions
C. It replaces the need for CT/MRI imaging
D. It is only used after discharge for rehabilitation planning
CORRECT ANSWER B — The NIHSS is a prognostic tool that quantifies deficits, provides a standardized common language
for the interdisciplinary team, and guides acute treatment decisions including thrombolytic eligibility.
RATIONALE NIHSS significance: (1) Quantifies stroke severity at presentation; (2) Guides tPA eligibility (typically NIHSS 4–
25 for thrombolysis); (3) Provides standardized communication among emergency physicians, neurologists,
and nurses; (4) Tracks improvement or deterioration over serial assessments; (5) Predicts outcomes (higher
scores = worse prognosis). It does NOT replace neuroimaging — CT/MRI is still required to rule out
hemorrhage before thrombolysis.
4. Item 1a — Level of Consciousness: A patient who requires strong or painful stimulation to respond would receive
what score?
A. 0 = Alert
B. 1 = Not alert; aroused with minor verbal stimulation
C. 2 = Not alert; requires strong or painful stimulation
D. 3 = Reflex movements only or totally unresponsive/coma
CORRECT ANSWER C — Score of 2. A patient requiring strong or repeated painful stimulation to elicit a response
(withdrawal, grimacing) receives a score of 2 for Item 1a.
RATIONALE LOC 1a scoring: 0 = Alert, keenly responsive; 1 = Not alert but arousable by minor verbal stimulation (calling
name); 2 = Not alert, requires strong or painful stimulation (sternal rub, nailbed pressure) to respond; 3 =
Responds only with reflex motor or autonomic effects, or totally unresponsive, flaccid, and areflexic (coma).
This item assesses the overall level of consciousness.
