PART I: THE PREVIEW
The Intro
Mastering the National Institutes of Health Stroke Scale (NIHSS) transforms the clinician into a
definitive diagnostic authority capable of instantly stratifying acute cerebrovascular crises and
guiding mechanical thrombectomy decisions. This elite gauntlet is engineered to rapidly
calibrate your clinical judgment to global board-certification standards, ensuring absolute
precision in high-stakes reperfusion environments.
The "Critical Axioms" Cheat Sheet
● Score What You See: Record the patient's actual performance in the exact moment of
testing, not their baseline or what you assume they can do.
● The First Attempt Rule: With the strict exception of Item 9 (Best Language), always
score the patient's first effort and never coach them.
● The "UN" (Untestable) Mandate: Reserve the "UN" designation exclusively for absolute
physical barriers, such as amputations, joint fusions, or endotracheal intubation for
, dysarthria.
● Coma Defaults: An unresponsive patient (Item 1a = 3) automatically defaults to
maximum deficit scores on subsequent subjective items, including Visual Fields (3),
Sensory (2), Language (3), and Inattention (2).
● The Posterior Circulation Blind Spot: The NIHSS heavily weights the anterior
circulation; isolated gait ataxia, cranial nerve deficits, or severe vertigo in posterior strokes
will artificially suppress the total score, necessitating advanced diagnostic suspicion.
PART II: THE ELITE TEST BANK
Tier 1 (Questions 1–18) - Foundational Syntax & Application
Q1: A patient requires repeated, painful sternal rubs to make non-stereotyped movements.
Based on the principles of the NIHSS Level of Consciousness (Item 1a), which score is the
MOST ACCURATE? A) 0 B) 1 C) 2 D) 3
● Answer: C (2)
● Distractor Analysis:
○ A is incorrect: The patient is clearly not alert or keenly responsive.
○ B is incorrect: A score of 1 applies to patients who arouse to minor verbal or light
physical stimulation.
○ D is incorrect: A score of 3 is strictly reserved for patients who are totally
unresponsive or respond only with reflex/autonomic posturing.
The Mentor's Analysis: The depth of obtundation directly dictates the Item 1a score, serving as
the foundation for the entire assessment. When facing an altered patient, the immediate priority
is establishing the minimum stimulus required for purposeful movement. By utilizing painful
stimulation successfully, you bypass the common trap of prematurely coding the patient as
comatose. Research confirms that accurate baseline scoring of LOC heavily predicts 90-day
mortality and functional independence. Professional Intuition: If pain elicits non-reflexive
movement, the score is 2; if pain yields only posturing or nothing, the score is 3.
Q2: An 82-year-old patient with acute right-sided weakness is asked their age and the current
month. The patient provides the correct age but states the wrong month. Based on the
principles of NIHSS LOC Questions (Item 1b), which score is CORRECT? A) 0 B) 1 C) 2 D) UN
● Answer: B (1)
● Distractor Analysis:
○ A is incorrect: The patient must answer both questions exactly correctly to score 0.
○ C is incorrect: The patient correctly answered one question, so they do not receive
a maximum impairment score of 2.
○ D is incorrect: Aphasia, dysarthria, or confusion are not valid reasons to use "UN".
The Mentor's Analysis: Item 1b tests raw orientation without coaching or leeway. When facing
partial orientation, the immediate priority is counting exact correct responses. By utilizing the
strict binary scoring of 0, 1, or 2, you bypass the common trap of giving partial credit for answers
that are "close".
Score Criterion for Item 1b (LOC Questions)
0 Answers both questions exactly right.
1 Answers one question exactly right.
2 Answers neither question correctly.
Professional Intuition: No partial credit, no coaching, no clues. Exact answers only.
, Q3: You instruct an acute stroke patient to open and close their eyes, and then to grip and
release your hand. The patient opens their eyes but fails to close them, and makes no attempt
to grip your hand. Based on the principles of NIHSS LOC Commands (Item 1c), what is the
APPROPRIATE score? A) 0 B) 1 C) 2 D) 3
● Answer: C (2)
● Distractor Analysis:
○ A is incorrect: The patient did not perform both tasks correctly.
○ B is incorrect: Opening the eyes without closing them does not constitute a full,
correct single task. They completed 0 full tasks.
○ D is incorrect: Item 1c is a 3-point scale ranging from 0 to 2; a score of 3 does not
exist.
The Mentor's Analysis: Complex commands require complete execution of all discrete steps.
When facing partial completion of a multi-step command, the immediate priority is scoring based
on fully completed tasks. By utilizing a score of 2 for failed execution, you bypass the common
trap of grading a half-finished command as a success. Professional Intuition: If the patient
cannot complete the entire sequence of a single command, they score 0 for that specific
task.
Q4: During testing of horizontal extraocular movements (Item 2), the patient exhibits a forced
deviation to the right. You perform an oculocephalic maneuver, and the patient's eyes cross the
midline to the left. Based on the principles of Best Gaze scoring, which action is the MOST
ACCURATE? A) 0 B) 1 C) 2 D) 3
● Answer: B (1)
● Distractor Analysis:
○ A is incorrect: The gaze is clearly abnormal, presenting as a forced deviation at
rest.
○ C is incorrect: A score of 2 is reserved for forced deviation that cannot be overcome
by voluntary or reflexive maneuvers.
○ D is incorrect: The maximum score for Item 2 is 2.
The Mentor's Analysis: Gaze paresis severity depends on reflexive override, distinguishing
cortical from brainstem pathology. When facing a forced gaze, the immediate priority is testing
the oculocephalic reflex. By utilizing this reflex to confirm partial motility, you bypass the
common trap of scoring a 2 just because the resting deviation looks severe. Professional
Intuition: If the eyes can cross the midline reflexively, the deficit is partial (Score 1).
Q5: You are evaluating Visual Fields (Item 3) in an obtunded patient who only responds to visual
threat and ignores your fingers in the upper and lower left quadrants. Based on the principles of
the NIHSS, which conclusion is MOST APPROPRIATE? A) Score 0 B) Score 1 C) Score 2 D)
Score 3
● Answer: C (Score 2)
● Distractor Analysis:
○ A is incorrect: Extinction to threat on one entire side indicates a definite field cut.
○ B is incorrect: Partial hemianopia (quadrantanopia) implies only one quadrant is
affected, not both upper and lower on the same side.
○ D is incorrect: The patient sees threats on the right side, ruling out bilateral
blindness.
The Mentor's Analysis: Visual threat testing is a validated fallback for aphasic or obtunded
patients. When facing poor comprehension, the immediate priority is checking reflexive blinking
to quadrant threats. By utilizing visual threat asymmetry, you bypass the common trap of
abandoning the visual field exam in confused patients. Professional Intuition: In stuporous
