NIHSS Score Administration and Interpretation 2 — Questions and Answers
Question 1: How does a higher NIHSS score generally relate to patient outcomes?
- Predicts better functional recovery
- Predicts worse functional outcome (Correct answer)
- Has no relationship to outcome
- Predicts shorter hospital stay
Correct answer: Predicts worse functional outcome
Higher NIHSS scores are consistently associated with worse functional outcomes, longer hospitalization, and higher mortality.
Question 2: The NIHSS was originally developed primarily for use in which context?
- Emergency triage protocols
- Clinical trials and stroke research (Correct answer)
- Primary care annual screening
- Inpatient rehabilitation planning
Correct answer: Clinical trials and stroke research
The NIHSS was developed in 1989 as a standardized tool for clinical stroke trials to allow consistent, reproducible measurement of neurological status.
Question 3: Which of the following does the NIHSS directly assess?
- Blood pressure and heart rate
- Neurological deficit severity (Correct answer)
- Stroke etiology and mechanism
- Cardiac rhythm abnormalities
Correct answer: Neurological deficit severity
The NIHSS directly measures the severity of neurological deficits caused by stroke, not vital signs or stroke etiology.
Question 4: Serial NIHSS assessments performed over time are most useful for which purpose?
- Determining stroke etiology
- Monitoring neurological improvement or deterioration (Correct answer)
- Guiding anticoagulation dosing directly
- Replacing the need for neuroimaging
Correct answer: Monitoring neurological improvement or deterioration
Repeated NIHSS assessments track real-time changes in neurological status, helping clinicians detect early deterioration or improvement after stroke.
Question 5: A patient who achieves an NIHSS score of 0 at 24 hours after stroke onset most likely has experienced:
- An incorrect initial stroke diagnosis
- Excellent neurological recovery (Correct answer)
- Permanent severe disability
- A worsening prognosis
Correct answer: Excellent neurological recovery
An NIHSS of 0 at 24 hours indicates complete or near-complete neurological recovery, which is associated with favorable functional outcomes.
Question 6: Large vessel occlusion strokes typically present with NIHSS scores in which range?
- 0-4
- 4-9
- 10 or higher (Correct answer)
- 1-8
Correct answer: 10 or higher
Large vessel occlusions commonly cause severe, multifocal neurological deficits resulting in NIHSS scores typically 10 or higher.
Question 7: The NIHSS is best described as which type of clinical tool?
- A diagnostic test differentiating hemorrhagic from ischemic stroke
- A validated standardized severity scale for acute stroke (Correct answer)
- A tool predicting 90-day mortality exclusively
- A rehabilitation assessment for post-acute care only
Correct answer: A validated standardized severity scale for acute stroke
The NIHSS is a validated, widely used standardized scale for measuring the severity of acute stroke neurological deficits in clinical and research settings.
