Final answer:
An NIHSS total score of 6 to 15 is considered a moderate stroke.
Step-by-step explanation:
An NIHSS total score of 6 to 15 is considered a moderate stroke. The NIHSS, or National Institutes of Health Stroke Scale, is a standardized tool used to assess the severity of a stroke and its impact on the patient's neurological functions. It evaluates various aspects such as consciousness, speech, motor function, and sensory function. A score within the moderate range indicates a significant impairment in neurological function but not as severe as a severe stroke.
