NIHSS HEALTHSTREAM TEST EXAM PREP 2026 QUESTIONS
WITH VERIFIED ANSWERS DETAILED RATIONALES GRADED
A+
Part I: Foundations, Purpose & Psychometrics (Questions 1–30)
1. The National Institutes of Health Stroke Scale (NIHSS) was originally
developed for which primary purpose?
A. To determine the exact anatomical location of a cerebral infarction
B. To measure stroke severity and guide treatment decisions in acute ischemic
stroke
C. To replace neuroimaging in the diagnosis of hemorrhagic stroke
D. To assess long-term functional outcomes at 90 days post-stroke
Rationale: The NIHSS is a 15-component impairment scale designed to measure
stroke severity and neurologic deficit in acute ischemic stroke; it is not designed to
localize infarcts anatomically or replace neuroimaging .
2. What is the maximum possible total score on the standard NIHSS?
A. 31
B. 36
C. 42
D. 54
1|Page
,Page 2 of 77
Rationale: The NIHSS total score ranges from 0 to 42, with the 15 scored
components using ordinal scales of 0–2, 0–3, or 0–4 .
3. According to standard NIHSS severity stratification, a total score of 12 would be
classified as:
A. Mild stroke
B. Moderate stroke
C. Moderate to severe stroke
D. Severe stroke
Rationale: Standard NIHSS severity stratification is: 0 = no stroke; 1–4 = mild; 5–
15 = moderate; 16–20 = moderate to severe; 21–42 = severe .
4. An NIHSS score of 1–4 indicates which level of stroke severity?
A. No stroke
B. Minor stroke
C. Moderate stroke
D. Severe stroke
Rationale: Scores of 1–4 indicate a minor stroke, 5–15 moderate, 16–20 moderate
to severe, and 21–42 severe .
5. Which organization developed the NIH Stroke Scale?
A. American Heart Association
B. American Stroke Association
C. National Institute of Neurological Disorders and Stroke (NINDS)
D. Centers for Disease Control and Prevention
Rationale: The NIHSS was developed by the National Institute of Neurological
Disorders and Stroke (NINDS) in 1989 .

6. The NIHSS is best described as which type of assessment instrument?
A. A diagnostic tool for identifying stroke subtype
B. A clinical evaluation tool to quantify neurologic deficit and stroke severity
C. A functional outcome measure for long-term disability
D. A neuroimaging interpretation scale
Rationale: The NIHSS is a clinical evaluation instrument used to quantify the
effects of acute cerebral ischemia and assess stroke severity; it is not a diagnostic
tool for stroke subtype .
7. How many scored components (items) are included in the standard NIHSS?
A. 7
B. 9
C. 11
D. 15
Rationale: The NIHSS has 11 items, but several items are scored separately for
left and right (e.g., motor arm, motor leg), resulting in 15 scored components .
8. What is the primary purpose of the NIHSS in clinical practice?
A. To determine the exact cause of a stroke
B. To quantify neurologic deficit, guide treatment decisions, and monitor
changes over time
C. To replace a comprehensive neurologic examination
D. To assess only motor function
Rationale: The NIHSS quantifies neurologic deficit, aids in treatment decisions
(e.g., thrombolytic eligibility), and facilitates serial monitoring .

9. In February 2025, HealthStream added which certification course to its hStream
benefits?
A. Advanced Cardiac Life Support (ACLS)
B. NIH Stroke Scale (NIHSS) Certification
C. Pediatric Advanced Life Support (PALS)
D. Trauma Nursing Core Course (TNCC)
Rationale: HealthStream added the NIHSS Certification course to its hStream
benefits in February 2025 .
10. How long is the adult NIHSS certification through HealthStream valid?
A. 6 months
B. 1 year or 2 years
C. 3 years
D. 5 years
Rationale: HealthStream offers both 1-year and 2-year adult NIHSS certification
options, depending on organizational requirements .
11. When do the free APEX Innovations: NIH Stroke Scale Training courses
permanently expire?
A. January 31, 2026
B. March 1, 2026
C. August 5, 2026
D. December 31, 2026
Rationale: The APEX Innovations: NIH Stroke Scale Training and Certification
courses permanently expire on August 5, 2026 .
