SECTION I: FOUNDATIONS OF THE NIH STROKE SCALE
1.1 History, Purpose & Psychometric Properties
**Question 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
**CorreCt Answer: B**
**Rationale:** The NIHSS is a 15-item impairment scale designed to measure stroke
severity and neurologic deficit in acute ischemic stroke. It was originally developed in 1989 and
is now widely used as an outcome measure in recombinant tissue plasminogen activator (rtPA)
stroke trials. It is not designed to localize infarcts anatomically, replace neuroimaging, or assess
long-term functional outcomes (which are measured by scales such as the modified Rankin
Scale).

**Question 2**
What is the maximum possible total score on the standard 15-item NIHSS?
A) 31
B) 36
C) 42
D) 54
**CorreCt Answer: C**
**Rationale:** The NIHSS total score ranges from 0 to 42. The 15 items are scored on
ordinal scales ranging from 0 to 2, 0 to 3, or 0 to 4. The maximum score of 42 represents the
most severe neurologic deficit. A score of 0 indicates no measurable deficit.
---
**Question 3**
According to standard NIHSS severity stratification, a total score of 12 would be classified as:
A) Mild stroke
B) Moderate stroke
