NIH Stroke Scale Test: A Comprehensive Guide and Quizlet-Style Practice

The National Institutes of Health Stroke Scale (NIHSS) is a standardized neurological examination used to evaluate stroke severity. It's crucial for healthcare professionals to accurately assess stroke patients, guiding treatment decisions and predicting prognosis. While this article won't replace formal medical training, it aims to provide a comprehensive overview of the NIHSS and offer a Quizlet-style practice experience to enhance understanding. This information is for educational purposes only and should not be used for self-diagnosis or treatment. Always consult with a qualified medical professional for any health concerns.

Understanding the NIHSS: Components and Scoring

The NIHSS consists of 11 items, each assessing a specific neurological function. Each item receives a score ranging from 0 (normal) to a maximum score specific to that item. The total score ranges from 0 to 42, with higher scores indicating greater stroke severity. The components are:

1. Level of Consciousness (LOC):

• Score 0: Alert
• Score 1: Not alert, but arousable by minor stimulation to verbal stimuli
• Score 2: Not alert, requires repeated stimulation to arousal
• Score 3: Unresponsive

This assesses the patient's responsiveness to their environment.

2. Horizontal Gaze Palsy:

• Score 0: Normal
• Score 1: Partial gaze palsy
• Score 2: Forced deviation or total gaze paresis

This evaluates eye movement, looking for any weakness or paralysis.

3. Vertical Gaze Palsy:

• Score 0: Normal
• Score 1: Partial gaze palsy
• Score 2: Forced deviation or total gaze paresis

This assesses vertical eye movements, similar to horizontal gaze palsy.

4. Visual Fields:

• Score 0: No visual field loss
• Score 1: Partial hemianopia
• Score 2: Complete hemianopia

This tests for visual field defects, often a significant indicator of stroke.

5. Facial Palsy:

• Score 0: Normal symmetrical
• Score 1: Minor paralysis (flattening of the nasolabial fold)
• Score 2: Partial paralysis (total or near-total paralysis of lower face)

This assesses facial muscle weakness or paralysis.

6. Motor Arm (Right):

• Scores range from 0-4 based on strength testing (0: Normal, 4: No movement). This assesses upper limb strength on the right side. The scoring is based on a strength scale, assessing the ability to hold the arm against gravity or resistance.

7. Motor Arm (Left):

• Scores range from 0-4 based on strength testing (0: Normal, 4: No movement). This assesses upper limb strength on the left side, mirroring the scoring for the right arm.

8. Motor Leg (Right):

• Scores range from 0-4 based on strength testing (0: Normal, 4: No movement). This evaluates lower limb strength on the right side, using the same scoring as the arms.

9. Motor Leg (Left):

• Scores range from 0-4 based on strength testing (0: Normal, 4: No movement). This assesses lower limb strength on the left side, mirroring the right leg assessment.

10. Limb Ataxia:

• Score 0: Absent
• Score 1: Present in one limb
• Score 2: Present in two limbs

This evaluates the coordination and balance of the limbs.

11. Sensory:

• Score 0: Normal
• Score 1: Mild to moderate sensory loss
• Score 2: Severe to total sensory loss

This assesses sensory function, detecting any loss of feeling or sensation.

12. Dysarthria:

• Score 0: Normal
• Score 1: Mild to moderate dysarthria
• Score 2: Severe dysarthria

This evaluates speech clarity and articulation.

13. Aphasia:

• Score 0: Normal
• Score 1: Mild to moderate aphasia
• Score 2: Severe aphasia

This assesses language comprehension and expression.

Interpreting the NIHSS Score

The NIHSS score is crucial for guiding treatment decisions. A higher score typically indicates more severe stroke and a potentially poorer prognosis. The score is used to:

• Determine treatment eligibility: Specific treatments, such as tPA (tissue plasminogen activator), have eligibility criteria often based on the NIHSS score.
• Predict outcome: The NIHSS score can help predict functional recovery after a stroke.
• Monitor progress: Repeated NIHSS assessments can track the patient's neurological improvement or deterioration.

It's important to remember that the NIHSS score is just one factor in overall stroke management. Other factors such as age, medical history, and comorbidities must also be considered.

NIHSS Quizlet-Style Practice Questions

Now let's test your knowledge with some practice questions in a Quizlet-style format. Remember, these are for educational purposes only and should not replace professional training.

Question 1: A patient is alert and oriented but exhibits a slight flattening of the nasolabial fold on the right side of their face. What is the likely score for Facial Palsy?

(a) 0 (b) 1 (c) 2 (d) 3

Answer: (b) 1

Question 2: A patient shows complete loss of vision in their left visual field. What is the likely score for Visual Fields?

(a) 0 (b) 1 (c) 2 (d) 3

Answer: (c) 2

Question 3: A patient is unable to move their right arm against gravity. What would be the potential score for Motor Arm (Right)?

(a) 0 (b) 1 (c) 3 (d) 4

Answer: (d) 4 (Depending on the level of movement. 4 represents no movement.)

Question 4: A patient demonstrates severe difficulty with speech articulation. What is the score for Dysarthria?

(a) 0 (b) 1 (c) 2 (d) 3

Answer: (c) 2

Question 5: The patient is unresponsive to any stimuli. What is their Level of Consciousness score?

(a) 0 (b) 1 (c) 2 (d) 3

Answer: (d) 3

Question 6: A patient shows mild difficulty understanding language. What is the likely score for Aphasia?

(a) 0 (b) 1 (c) 2 (d) 3

Answer: (b) 1

Question 7: The patient exhibits ataxia in both legs. What is the score for Limb Ataxia?

(a) 0 (b) 1 (c) 2 (d) 3

Answer: (c) 2

Question 8: The patient has difficulty moving their left leg against resistance, showing some movement but unable to maintain it. What would be a possible score for Motor Leg (Left)? (This is subjective and requires clinical judgment, multiple answers could be viable)

(a) 0 (b) 1 (c) 2 (d) 3

Answer: (c) or (d) This would depend on the specifics of the clinical examination and how the clinician interprets the level of motor weakness.

Answer: (c) 2

Beyond the Quiz: Further Learning and Resources

This article provides a foundational understanding of the NIHSS. For healthcare professionals, comprehensive training and practical experience are essential for accurate assessment. This includes understanding the nuances of scoring and interpreting findings within the context of the patient's overall clinical presentation. Always refer to official guidelines and resources for the most up-to-date information and best practices. Remember, this information is for educational purposes only and does not constitute medical advice.

This quizlet-style approach aims to facilitate comprehension and retention. However, practical application and supervision under experienced clinicians are crucial for mastering the NIHSS.
