NIH STROKE SCALE (NIHSS) [2026/ 2027] COMPREHENSIVE
EXAM QUESTIONS AND 100% VERIFIED ANSWERS WITH
RATIONALES GRADED A+ LATEST
1. A patient presents with sudden onset right facial droop and slurred speech. On assessment, the patient raises both arms but the right drifts downward. What is the most likely NIHSS score for arm motor function? A. 0 B. 1 C. 2 D. 3
Answer: C. 2 Rationale: NIHSS scores arm motor function as 0 (no drift), 1 (drift before 10 seconds), 2 (falls rapidly), 3 (no movement). Right arm drifts downward indicates moderate weakness, scored as 2.
2. During the NIHSS assessment, the patient cannot answer the question, "What month is it?" and "How old are you?" What score is assigned for language? A. 0 B .......................................................................................................................................................................................................... 1 C .......................................................................................................................................................................................................... 1 D .......................................................................................................................................................................................................... 1 Answer: D Rationale: Language assessment scores 0 for normal, 1 for mild aphasia, 2 for severe aphasia, and 3 for mute/nonverbal. Complete inability to answer scores 3. ................ **Error! Bookmark not defined.
- A patient has right visual field loss in both eyes. What is the NIHSS visual field score?** A. 0
B. 1
C. 2
D. 3
Answer: C. 2 Rationale: NIHSS visual field scoring: 0 = no visual loss, 1 = partial hemianopia, 2 = complete hemianopia, 3 = bilateral blindness. Right hemianopia in both eyes is complete in the right visual field, scoring 2.
4. A patient demonstrates left leg drift for 8 seconds but can hold the leg up. NIHSS lower limb motor score is: A. 0 B. 1 C. 2 D. 3
Answer: B. 1 Rationale: Score 0 = no drift, 1 = drift, 2 = falls rapidly, 3 = no movement. Drift less than 10 seconds is mild, scored as 1.
5. During NIHSS assessment, the patient is completely alert but requires repeated stimulation to respond. Level of consciousness (LOC) question score: A. 0 B. 1 C. 2 D. 3
Answer: B. 1 Rationale: LOC scoring: 0 = alert, 1 = drowsy/needs stimulation, 2 = responds only with effort, 3 = unresponsive.
6. A patient has complete left hemiplegia and cannot move the left arm or leg. NIHSS motor score for left arm and leg: A. 3 + 3 B. 2 + 2
D. 5
Answer: B. 3 Rationale: LOC = 0, best gaze = 0, visual fields = 0, facial palsy = 0, motor arm right = 1 (drift <10 sec), motor leg right = 1, dysarthria = 1 → total = 3.
10. During NIHSS assessment, patient exhibits left homonymous hemianopia. What is the score for visual field assessment? A. 0 B. 1 C. 2 D. 3
Answer: C. 2 Rationale: Complete loss in half of the visual field is scored as 2.
11. Patient cannot answer questions but can follow simple commands by gestures. NIHSS score for language: A. 0 B. 1 C. 2 D. 3
Answer: C. 2 Rationale: Severe aphasia: patient communicates minimally and cannot answer questions but can respond nonverbally.
12. During NIHSS facial assessment, the patient shows right lower facial droop only when smiling. Score: A. 0 B. 1 C. 2 D. 3
Answer: B. 1 Rationale: Facial palsy scoring: 0 = normal, 1 = minor (flattening of nasolabial fold, minor asymmetry), 2 = partial, 3 = complete paralysis.
13. A patient demonstrates severe aphasia with incomprehensible speech. NIHSS language score: A. 0 B. 1 C. 2 D. 3
Answer: C. 2 Rationale: Severe aphasia: patient speaks but is mostly unintelligible.
14. Patient is alert, oriented, follows commands, no facial palsy, no gaze deviation, mild left arm drift, mild dysarthria. NIHSS approximate total score: A. 2 B. 3 C. 4 D. 5
Answer: A. 2
Rationale: Left arm drift = 1, dysarthria = 1, other categories = 0 → total 2. Check all: LOC 0, gaze 0, visual 0, facial 0, motor arm = 1, motor leg = 0, limb ataxia = 0, sensory = 0, language = 0, dysarthria =1, extinction/inattention=0 → total = 2 (Wait calculation: arm drift =1 + dysarthria =1 → total 2). Correct total = 2 → correction needed. Rationale: Total NIHSS is sum of all subscales; only left arm drift (1) and dysarthria (1) are abnormal, other categories score 0 → total 2.
15. A patient shows forced gaze deviation to the left, left facial droop, and cannot raise the left arm against gravity. NIHSS total approximate score: A. 5 B. 7 C. 9 D. 11
Rationale: Right arm =3, right leg =3, facial droop = 3, gaze deviation =2, language =3 (mute), other items assume 0. Total = 3+3+3+2+3=14. Add sensory?
If normal 0, extinction 0 → total =14. Adjust answer closest: 18 may overestimate. Correct total = 14.
19. Which NIHSS subscale evaluates a patient’s ability to follow two commands like “open and close your eyes” and “grip and release your hand”? A. LOC B. Motor function C. Level of Consciousness – Commands D. Language
Answer: C. Level of Consciousness – Commands Rationale: LOC–Commands evaluates ability to follow simple instructions, scored 0–2.
20. Patient responds slowly to verbal stimulus, answers questions with delay, mild right facial droop. NIHSS LOC score: A. 0 B. 1 C. 2 D. 3
Answer: B. 1 Rationale: Mild delay in responsiveness indicates drowsiness, scores 1.
21. A patient exhibits right arm drift that falls before 10 seconds, right leg can be held up for more than 5 seconds, mild right facial droop, and mild dysarthria. Total NIHSS score? A. 2 B. 3 C. 4
D. 5
Answer: B. 3 Rationale: Right arm drift <10s = 1, right leg held up >5s = 0, facial droop mild = 1, dysarthria mild = 1. Total = 1+0+1+1=3.
22. During assessment, a patient cannot look left voluntarily, eyes deviate to the right. Gaze score? A. 0 B. 1 C. 2 D. 3
Answer: C. 2 Rationale: Forced gaze deviation scores 2. Partial gaze palsy scores 1. Complete inability to move eyes opposite to deviation indicates forced deviation.
23. A patient answers questions slowly and hesitantly but comprehensibly. Language score? A. 0 B. 1 C. 2 D. 3

Answer: B. 1 + 1 Rationale: Drift <10s for arm and leg = mild weakness, each scores 1.
27. During NIHSS sensory assessment, patient cannot feel light touch on the right arm and leg. Score? A. 0 B. 1 C. 2 D. 3
Answer: B. 1 Rationale: Partial sensory loss = 1. Complete loss would score 2.
28. A patient demonstrates right facial droop involving the entire right side. Facial palsy score? A. 0 B. 1 C. 2 D. 3
Answer: C. 2 Rationale: Partial or complete facial weakness of one side = 2. Minor flattening or asymmetry = 1.
29. Patient is mute and cannot follow commands. LOC verbal score? A. 0
B. 1
C. 2
D. 3
Answer: C. 2 Rationale: LOC verbal response scoring: 0 = alert/oriented, 1 = drowsy, 2 = responds only with effort or nonverbal, 3 = unresponsive. Mute but can respond nonverbally = 2.
30. Patient has severe left-sided neglect during double simultaneous stimulation. Extinction/inattention score? A. 0 B. 1 C. 2 D. 3
Answer: C. 2 Rationale: Profound neglect or extinction = 2; mild extinction =1; none =0.
31. A patient has dysarthria but is fully intelligible. Dysarthria score? A. 0 B. 1 C. 2 D. 3
Answer: B. 1 Rationale: Mild to moderate slurring that does not prevent understanding = 1. Severe = 2.
32. Patient cannot answer orientation questions but follows commands. LOC questions score? A. 0 B. 1 C. 2
35. Patient is alert, oriented, no limb weakness, no visual deficits, mild dysarthria. NIHSS total score? A. 0 B. 1 C. 2 D. 3

36. Patient cannot raise left arm against gravity; left leg drift <10s; mild left facial droop; severe aphasia. Total NIHSS score? A. 7 B. 8 C. 9 D. 10
Answer: A. 7 Rationale: Left arm = 3, left leg =1, facial =1, language =2 (severe aphasia), total =3+1+1+2=7? Also include gaze/LOC 0, visual 0, dysarthria=0, extinction=0 → total =7. Corrected total = 7 → answer = A. 7
37. Patient demonstrates partial left homonymous hemianopia. Visual field score? A. 0 B. 1 C. 2 D. 3
Answer: B. 1 Rationale: Partial hemianopia = 1; complete hemianopia = 2.
38. Patient follows one-step commands but is unable to answer two-step questions correctly. LOC commands score?
A. 0

Answer: 1 Rationale: Inability to correctly perform commands scores 1 per subitem.
39. A patient is alert, has mild right arm drift, mild right leg drift, no facial droop, no gaze deviation, normal language. Total NIHSS score? A. 2 B. 3 C. 4 D. 5
Answer: A. 2
Rationale: Right arm drift =1, right leg drift =1, other subscales =0 → total 2.
