Mixed Deck — All NIHSS Topics Flashcards

Which of the following deficits is assessed under the "Motor Arm" section of the NIHSS?

Answer: Arm movement and strength

The "Motor Arm" section evaluates the movement and strength of the arms.

A patient in the NIHSS Group B category is BEST described as someone who:

Answer: Has a known communication barrier, altered consciousness, intubation, or significant aphasia that limits the standard exam

Group B patients are those whose neurological deficits or medical status (e.g., intubation, profound aphasia, altered consciousness) create barriers to the standard NIHSS examination format. Group A patients are cooperative and able to follow standard instructions.

A patient has bilateral occipital lobe infarcts from a basilar artery stroke. They are cortically blind but deny being blind (Anton syndrome). How should NIHSS item 3 be scored?

Answer: 3, because bilateral blindness is present regardless of denial

Objective findings of bilateral blindness are scored 3 even if the patient denies the deficit due to anosognosia (Anton syndrome).

What is the difference between reliability and validity in National Institutes of Health Stroke Scale assessment?

Answer: Reliability refers to consistency of results; validity refers to accuracy of measurement

Reliability means the assessment produces consistent, stable results across repeated administrations. Validity means the assessment accurately measures what it is intended to measure. Both are needed for quality assessment.

Which approach is most effective for mastering sensory testing in National Institutes of Health Stroke Scale?

Answer: Combining theoretical study with practical application and regular review

The most effective approach combines theoretical understanding with practical application, reinforced by regular review and assessment, enabling deeper comprehension and long-term retention.

What does "language proficiency" mean in National Institutes of Health Stroke Scale?

Answer: The ability to use language effectively for communication in various contexts

Language proficiency encompasses the ability to understand and produce language effectively across different contexts, including reading, writing, speaking, and listening in academic, professional, and social settings.

Answer: patient 3

The numerical values represent the scores obtained by patients on different components of a neurological assessment, possibly using a standardized scale such as the NIHSS (National Institutes of Health Stroke Scale). Each score corresponds to a specific aspect of neurological function, such as wakefulness, motor coordination, sensory perception, and language comprehension

4-Facial Palsy: "Raise eyebrows and show me your teeth." Look for droopiness in face or mouth5-"Lift your left arm/Lift your right arm/Lift your left or right leg) 10 sec vs 5 sec.

Answer: Motor

Both instructions—checking for facial droopiness and asking the patient to lift their arms or legs—assess motor function, focusing on muscle control and strength.

On item 1c (LOC Commands), can the examiner pantomime or demonstrate the command if the patient does not respond to verbal instruction alone?

Answer: No — the verbal command may be repeated once, but gestures or demonstrations are not allowed

The NIHSS protocol permits the verbal command to be repeated once if the patient does not respond. However, pantomiming or physically demonstrating the command is not allowed, as it would bias the assessment of the patient's ability to follow verbal commands.

A patient has a right homonymous hemianopia detected during NIHSS visual field testing. What score does the examiner assign?

Answer: 1

Partial visual field loss including hemianopia in one hemifield scores 1 on NIHSS item 3.

How is the patient's ability to understand and use language evaluated in the NIHSS?

Answer: By asking the patient to name objects and describe a picture

The language section assesses comprehension and expression by having the patient name objects and describe a picture.

During NIHSS assessment, a patient with left middle cerebral artery stroke shows visual field neglect but no true field cut on careful testing. What is the NIHSS item 3 score?

Answer: 1

Visual neglect without a true field cut is scored as partial visual loss (1) under NIHSS item 3.

What is the relationship between theory and practice in National Institutes of Health Stroke Scale level of consciousness?

Answer: Theory provides the foundation and framework that guides effective practical application

Theory and practice are complementary: theoretical knowledge provides the conceptual framework and understanding that guides effective, evidence-based practical application in professional settings.

When scoring the Best Gaze item on a Group B patient who cannot follow verbal commands, which approach is correct?

Answer: Use oculocephalic (doll's-eye) maneuver to assess eye movement and score based on observed range of motion

The NIHSS explicitly allows the use of oculocephalic (doll's-eye) testing when a patient cannot voluntarily follow gaze commands. The examiner scores based on the range and conjugacy of eye movement observed, making the item testable even in unresponsive patients.

What is a rubric used for in National Institutes of Health Stroke Scale assessment?

Answer: To define criteria and performance levels for evaluating work quality

A rubric is a scoring guide that defines specific criteria and describes performance levels for each criterion, providing consistent and transparent evaluation standards.

In National Institutes of Health Stroke Scale, why is visual field testing knowledge important for professional certification?

Answer: It demonstrates competence and ensures practitioners meet established standards

Professional certification in specific knowledge areas demonstrates that practitioners have met established competency standards, ensuring quality of service and public protection.

A patient holds their arm at 90° but it drifts downward before 10 seconds — however, it does not hit the bed or their lap. How is Motor Arm scored?

Answer: 1 — the arm drifts before 10 seconds but does not fall

A score of 1 is assigned when the arm drifts from the starting position before 10 seconds but does not fall all the way to the bed or the patient's lap. The distinction between score 1 (drift) and score 2 (falls completely) is critical.

Which of the following is NOT a component of the NIHSS?

Answer: Blood glucose levels

The NIHSS assesses neurological function, including consciousness, language, and motor skills, but not blood glucose levels.

An examiner presents two fingers simultaneously in the right and left upper quadrants. The patient reports seeing fingers only on the right. On isolated left field testing, the left upper field is intact. What is the correct NIHSS item 3 score and interpretation?

Answer: 1 — partial loss due to left visual extinction

Extinction to double simultaneous stimulation with intact fields when tested alone is scored as partial visual loss (1) under NIHSS item 3.

What does validity mean in the context of assessment within National Institutes of Health Stroke Scale?

Answer: The assessment measures what it is intended to measure

Validity refers to whether an assessment actually measures the construct or skill it claims to measure. A valid assessment produces meaningful and accurate results for its intended purpose.
