Nihss Stroke Scale Answers Group A

The NIH Stroke Scale (NIHSS) answers for Group A are a key resource for clinicians, students, and anyone preparing for stroke certification exams. Understanding how each item is scored and what the correct responses look like helps ensure reliable neurological assessments in acute stroke care. Below is a full breakdown that explains the NIHSS, breaks down Group A items, provides sample answers, and offers practical tips for using the scale effectively in real‑world settings.

What Is the NIH Stroke Scale?

The NIH Stroke Scale is a standardized 11‑item neurological examination designed to quantify the severity of deficits caused by an acute stroke. Each item evaluates a specific function—such as level of consciousness, gaze, visual fields, facial palsy, motor strength, limb ataxia, sensory loss, language, dysarthria, and inattention—and assigns a score from 0 (normal) to a maximum that reflects the worst possible impairment. The total score ranges from 0 to 42, with higher numbers indicating more severe stroke impact.

Why the NIHSS matters

Provides an objective baseline for tracking neurological change over time.
Guides treatment decisions, including eligibility for thrombolysis or endovascular therapy.
Facilitates communication among multidisciplinary teams using a common language.
Serves as a research endpoint in clinical trials and quality‑improvement initiatives.

Overview of NIHSS Groups (A, B, and C)

To maintain test security and prevent rote memorization, the NIHSS certification program offers three equivalent versions of the scale: Group A, Group B, and Group C. Each group contains the same 11 items but uses different stimulus materials (pictures, sentences, and commands) so that examiners cannot simply recall answers from a previous attempt. All groups are psychometrically equivalent; a score of 10 in Group A carries the same clinical meaning as a score of 10 in Group B or Group C.

Purpose of grouping

Reduces cheating during online recertification.
Allows repeated testing without inflating scores due to familiarity.
Ensures that clinicians truly understand the scoring criteria rather than memorizing a key.

NIHSS Group A Items and Scoring

Below is each of the 11 NIHSS items as they appear in Group A, together with the scoring criteria. Familiarity with these definitions is essential before attempting to answer practice questions.

Item	Description (Group A Stimulus)	Scoring (0‑max)
1a. Motor Arm – Right	Same as 5a for the right arm. In real terms, motor Leg – Left**	Ask patient to lift leg 30° (if supine) and hold for 5 seconds. Day to day,
3. Now, dysarthria	Patient reads a standard list of words; examiner rates clarity.	0 = alert; 1 = drowsy but arousable; 2 = stuporous; 3 = comatose
1b. Level of Consciousness: Questions	Ask month and age. Day to day, level of Consciousness: Responsiveness**	Ask the patient to open eyes and respond to verbal command. So visual Fields**
**8. Now,	0 = no drift; 1 = drift before 5 s but does not hit bed; 2 = falls before 5 s; 3 = no effort against gravity; 4 = no movement
6b. So motor Leg – Right	Same as 6a for the right leg. In real terms, dull.	0 = no drift; 1 = drift before 10 s but does not hit bed; 2 = falls before 5 s; 3 = no effort against gravity; 4 = no movement
**5b.	Same scoring as 5a
**6a.	0 = no aphasia; 1 = mild‑to‑moderate aphasia; 2 = severe aphasia; 3 = mute, global aphasia
**10.	0 = normal; 1 = minor paralysis; 2 = partial paralysis; 3 = complete paralysis
**5a.	0 = normal; 1 = mild‑to‑moderate loss; 2 = severe to total loss
**9. That said,	0 = no visual loss; 1 = partial hemianopia; 2 = complete hemianopia; 3 = bilateral hemianopia (cortical blindness)
4. Day to day, motor Arm – Left	Ask patient to extend arm 90° (if sitting) or 45° (if supine) and hold for 10 seconds. Best Language**	Describe a picture (the “cookie‑theft” scene in Group A) and name items on a naming sheet. Even so,
1c. Facial Palsy	Show teeth or raise eyebrows; observe symmetry. Even so,	0 = both correct; 1 = one correct; 2 = neither correct
**2. This leads to	Same scoring as 6a
7. Consider this: sensory	Pinprick stimulation of face, arm, leg on both sides; compare sharp vs.	0 = normal; 1 = mild‑to‑moderate dysarthria; 2 = severe dysarthria
11. Limb Ataxia	Finger‑nose‑finger test (or heel‑to‑shin if unable to perform upper limb). Here's the thing — best Gaze**	Horizontal eye movements tested by asking patient to follow examiner’s finger to left and right. Level of Consciousness: Commands**

NIHSS Group A Answers (Sample Scenarios)

To illustrate how the scoring works in practice, consider the following hypothetical patient presentations. For each item, the correct Group A answer (score)

NIHSS Group A Answers (Sample Scenarios) – Continued

Below are concise vignettes that illustrate how each item is scored in practice. For each scenario, the examiner’s observation is noted, followed by the corresponding NIHSS score (the “Group A answer”). These examples assume the patient is able to cooperate unless otherwise stated.

Item	Scenario Description	Observed Finding	NIHSS Score
1a. Level of Consciousness: Responsiveness	The patient opens eyes spontaneously when spoken to, follows simple commands, and appears alert. Think about it:	Alert, responsive to verbal stimuli.	0
1b. And level of Consciousness: Questions	Asked “What month is it? ” and “How old are you?Now, ” The patient answers “July” correctly but says “I’m 45” when actually 68.	One question answered correctly.	1
1c. Level of Consciousness: Commands	Patient is asked to open and close eyes, then to grip and release the non‑paretic hand. In practice, they open/close eyes correctly but cannot grip/release the hand.	One of the two commands performed correctly. In real terms,	1
2. Best Gaze	When the examiner moves a finger horizontally, the patient’s eyes deviate to the left and cannot be brought past midline; however, with vigorous effort they can look toward the right.	Forced deviation to the left with inability to overcome.	2
3. Visual Fields	Confrontation testing shows the patient cannot see fingers presented in the left upper and lower quadrants of both eyes, but perceives stimuli in the right visual field.	Complete left homonymous hemianopia.	2
4. Facial Palsy	The patient smiles; the left side of the mouth does not rise, while forehead wrinkling is symmetric when asked to raise eyebrows.	Lower face weakness only (minor paralysis).	1
5a. Motor Arm – Left	The left arm is held at 90° (sitting) and begins to drift downward after ~4 seconds, never touching the bed.	Drift before 10 s but does not hit bed.	1
5b. Also, motor Arm – Right	The right arm cannot be lifted against gravity; the patient shows no effort when asked to extend the arm. Day to day,	No effort against gravity. Plus,	3
6a. Motor Leg – Left	The left leg lifts to 30° but falls to the bed after 2 seconds.	Falls before 5 s. But	2
6b. Motor Leg – Right	The right leg remains stationary; the patient makes no attempt to lift it despite encouragement.	No movement.	4
7. Worth adding: limb Ataxia	Finger‑nose‑finger testing reveals past‑pointing in the right hand; the left hand performs normally. On the flip side, heel‑to‑shin is intact bilaterally. That said,	Ataxia present in one limb. This leads to	1
8. Because of that, sensory	Pinprick on the left face, arm, and leg is perceived as dull; the right side senses sharp normally.	Mild‑to‑moderate sensory loss on the left. Consider this:	1
9. Here's the thing — best Language	The patient describes the cookie‑theft picture with short, telegraphic phrases (“boy… cookie… jar…”) and names only 2 of 10 items on the naming sheet. Still,	Moderate aphasia.	1
10. Dysarthria	While reading the standard word list, speech is slurred but intelligible with listener effort. Which means	Mild‑to‑moderate dysarthria.	1
11. Extinction and Inattention	Simultaneous tactile stimulation to both hands is perceived only on the right; visual double stimulation is sensed only on the right side.	Unilateral inattention (visual/tactile).

How to Use These Samples

Training: New clinicians can compare their observations against these benchmark answers to calibrate scoring accuracy.
Quality Assurance: Audit teams can review a random set of NIHSS assessments and verify that scores align with the documented findings.
Research Consistency: When pooling data across sites, referencing a common set of exemplar scenarios helps minimize inter‑rater variability.

Conclusion

The NIHSS remains the cornerstone for quantifying stroke severity, guiding treatment decisions, and predicting outcomes. Mastery of each item—through clear procedural knowledge and repeated practice with illustrative scenarios—ensures that scores reflect the patient’s true neurologic status rather than examiner bias. By internalizing the scoring nuances demonstrated in the Group A examples, clinicians can administer the NIHSS swiftly, reliably, and consistently, ultimately enhancing acute stroke care and facilitating meaningful clinical research.
