Question 1
A 68-year-old patient arrives in the emergency department 45 minutes after developing sudden right-sided
weakness and difficulty speaking. The stroke team prepares to perform the NIH Stroke Scale (NIHSS). What is
the primary purpose of the NIHSS?
A. To identify the exact artery affected by the stroke
B. To determine whether emergency surgery is required
C. To estimate the patient's rehabilitation expenses
,D. To objectively measure the severity of stroke-related neurological deficits
Correct Answer: D. To objectively measure the severity of stroke-related neurological deficits
Rationale:
The NIH Stroke Scale (NIHSS) is a standardized neurological assessment used to quantify the severity of stroke
deficits. It establishes a baseline neurological status, monitors changes over time, assists in treatment
decisions, and facilitates communication among healthcare providers.
Why the Other Options Are Incorrect
A. Vascular imaging, such as CT angiography or MR angiography, identifies the affected artery.
B. Surgical decisions depend on imaging findings and overall clinical evaluation, not the NIHSS alone.
C. The NIHSS is not designed to estimate rehabilitation costs.
Clinical Pearl:
Perform the baseline NIHSS as early as possible before reperfusion therapy whenever feasible.
NIHSS High-Yield Tip:
The NIHSS measures neurological impairment—it does not diagnose the underlying cause of the stroke.
Question 2
A patient with suspected acute ischemic stroke undergoes an NIHSS assessment immediately after arrival.
Which advantage of the NIHSS is most important during the initial evaluation?
A. It provides a standardized method for measuring neurological deficits.
B. It accurately distinguishes ischemic stroke from hemorrhagic stroke.
C. It replaces the need for emergency brain imaging.
D. It predicts the exact location of cerebral infarction.
Correct Answer: A. It provides a standardized method for measuring neurological deficits.
Rationale:
The NIHSS standardizes neurological assessment, allowing healthcare providers to communicate findings
consistently, compare examinations over time, and evaluate treatment effectiveness.
Why the Other Options Are Incorrect
B. Brain imaging is required to differentiate ischemic from hemorrhagic stroke.
C. The NIHSS complements—but never replaces—CT or MRI.
D. Although deficits may suggest lesion location, the NIHSS cannot precisely localize cerebral injury.
Clinical Pearl:
Using the same standardized assessment improves communication during stroke alerts and patient handoffs.
, NIHSS High-Yield Tip:
Consistency among examiners is one of the greatest strengths of the NIHSS.
Question 3
A hospital is training clinicians to perform the NIH Stroke Scale. Which individual is qualified to administer the
NIHSS after completing the required certification?
A. Only board-certified neurologists
B. Any licensed healthcare professional who has completed NIHSS training
C. Only emergency department physicians
D. Only registered nurses working in stroke units
Correct Answer: B. Any licensed healthcare professional who has completed NIHSS training
Rationale:
The NIHSS is intended for use by trained healthcare professionals, including physicians, nurses, advanced
practice providers, paramedics, and therapists who have successfully completed NIHSS certification.
Why the Other Options Are Incorrect
A. Neurologists commonly perform the NIHSS but are not the only qualified professionals.
C. Emergency physicians are not the exclusive providers authorized to administer the NIHSS.
D. Nurses frequently perform the NIHSS, but certification is available to many healthcare disciplines.
Clinical Pearl:
Regular recertification helps maintain scoring accuracy and inter-rater reliability.
NIHSS High-Yield Tip:
Proper training is more important than professional title when performing the NIHSS.
Question 4
Two hours after receiving intravenous thrombolytic therapy, a patient's NIHSS score decreases from 15 to 8.
What does this finding most likely indicate?
A. The patient has developed cerebral edema.
B. The original assessment was inaccurate.
C. The patient's neurological function has improved.
D. Intracranial hemorrhage has occurred.
Correct Answer: C. The patient's neurological function has improved.
,Rationale:
A lower NIHSS score reflects improvement in neurological deficits and often indicates a favorable response to
reperfusion therapy. Serial assessments help clinicians evaluate treatment effectiveness and detect
complications.
Why the Other Options Are Incorrect
A. Cerebral edema generally causes worsening neurological findings.
B. Improvement in score usually represents genuine neurological recovery.
D. Intracranial hemorrhage typically causes neurological deterioration rather than improvement.
Clinical Pearl:
Always compare current NIHSS findings with previous scores to identify trends.
NIHSS High-Yield Tip:
An improving NIHSS score after treatment is generally associated with better functional outcomes.
Question 5
During the initial evaluation of a patient with acute stroke symptoms, the clinician records an NIHSS score of
24. How should this result be interpreted?
A. Moderate neurological impairment
B. Mild neurological impairment
C. No measurable neurological deficit
D. Severe neurological impairment
Correct Answer: D. Severe neurological impairment
Rationale:
An NIHSS score of 24 represents severe neurological impairment. Patients with scores greater than 20 often
have extensive deficits and require intensive monitoring and comprehensive stroke management.
Why the Other Options Are Incorrect
A. Moderate strokes generally have lower NIHSS scores.
B. Mild strokes usually score between 1 and 4.
C. A score of 0 indicates no measurable neurological deficit.
Clinical Pearl:
Higher NIHSS scores are associated with larger strokes, increased complication rates, and poorer functional
outcomes.
, NIHSS High-Yield Tip:
Remember these commonly used severity ranges:
• 0: No stroke symptoms
• 1–4: Minor stroke
• 5–15: Moderate stroke
• 16–20: Moderate to severe stroke
• 21–42: Severe stroke
Question 6
A nurse begins an NIHSS assessment on a patient who appears drowsy but awakens to verbal stimulation and
follows simple commands. According to NIHSS principles, how should the examiner approach scoring?
A. Score only the neurological findings demonstrated during the examination.
B. Assign the best possible score because the patient can follow commands.
C. Estimate the score based on information provided by family members.
D. Delay the examination until the patient is fully alert.
Correct Answer: A. Score only the neurological findings demonstrated during the examination.
Rationale:
The NIHSS is an objective observational assessment. Every item is scored according to the patient's actual
performance during the examination without estimating ability or considering what the patient might be
capable of doing later.
Why the Other Options Are Incorrect
B. The NIHSS measures actual neurological deficits, not the patient's effort or willingness.
C. Family reports may provide valuable history but are not used to assign NIHSS scores.
D. Delaying the assessment may postpone important treatment decisions.
Clinical Pearl:
If an item cannot be completed because of a neurological deficit, score the observed deficit rather than making
assumptions.
NIHSS High-Yield Tip:
One of the fundamental NIHSS rules is: Score what you see—not what you think.
Question 7
,Which patient should receive an immediate NIHSS assessment?
A. A patient with chronic diabetic neuropathy and unchanged numbness in both feet.
B. A patient with Parkinson disease who has had a resting tremor for several years.
C. A patient who suddenly develops left arm weakness and slurred speech while eating lunch.
D. A patient reporting intermittent dizziness for the past month without new neurological findings.
Correct Answer: C. A patient who suddenly develops left arm weakness and slurred speech while eating
lunch.
Rationale:
Sudden focal neurological deficits strongly suggest an acute stroke and require immediate NIHSS assessment to
establish baseline neurological status and guide urgent treatment decisions.
Why the Other Options Are Incorrect
A. Chronic neuropathy is not an indication for emergency stroke assessment.
B. Parkinson disease causes chronic neurological symptoms rather than sudden stroke deficits.
D. Long-standing dizziness without acute neurological changes is less suggestive of an acute stroke.
Clinical Pearl:
The NIHSS is intended for patients with acute neurological changes, not chronic neurological disorders.
NIHSS High-Yield Tip:
Think BE FAST—Balance, Eyes, Face, Arm, Speech, Time—when identifying patients who require an immediate
NIHSS.
Question 8
A stroke coordinator explains why every certified examiner follows the same NIHSS instructions. What is the
primary reason for using a standardized examination?
A. It shortens the patient's hospital stay.
B. It guarantees identical NIHSS scores for every patient.
C. It eliminates the need for neurological consultation.
D. It improves consistency and reliability among examiners.
Correct Answer: D. It improves consistency and reliability among examiners.
Rationale:
The NIHSS was designed to minimize variation between examiners. Standardized instructions improve inter-
rater reliability, making serial examinations more accurate and meaningful.
Why the Other Options Are Incorrect
, A. Hospital length of stay depends on many clinical factors.
B. Standardization improves accuracy but does not guarantee identical scores.
C. Neurology consultation remains an essential part of comprehensive stroke care.
Clinical Pearl:
Using the same examination technique at every assessment allows clinicians to detect true neurological
change.
NIHSS High-Yield Tip:
Reliable serial NIHSS scores depend on performing each assessment exactly the same way.
Question 9
A patient receives an NIHSS score of 0 during the initial evaluation. Which interpretation is most appropriate?
A. The patient has no measurable neurological deficits on the NIHSS examination.
B. The patient definitely did not experience a stroke.
C. Brain imaging will be completely normal.
D. The patient has experienced only a transient ischemic attack.
Correct Answer: A. The patient has no measurable neurological deficits on the NIHSS examination.
Rationale:
An NIHSS score of 0 indicates that no neurological deficits were identified during the examination. However,
certain strokes—especially posterior circulation strokes—may present with minimal or no NIHSS abnormalities.
Why the Other Options Are Incorrect
B. A patient may still have an acute stroke despite a low or normal NIHSS score.
C. Neuroimaging may reveal abnormalities even when the NIHSS is 0.
D. The NIHSS alone cannot distinguish a transient ischemic attack from an acute stroke.
Clinical Pearl:
Always interpret the NIHSS together with the patient's symptoms, physical examination, and brain imaging.
NIHSS High-Yield Tip:
A normal NIHSS score does not completely rule out an acute stroke.
Question 10
Before starting the NIHSS examination, what is the examiner's most appropriate first action?
A. Review the patient's rehabilitation goals.
