Which components are assessed using the National Institutes of Health Stroke Scale (NIHSS)?

The National Institutes of Health Stroke Scale (NIHSS) is a tool specifically designed to assess and quantify the impairment caused by a stroke. It focuses on several key neurological functions that are critical for determining the severity of a stroke and can help guide treatment options and predict outcomes.

One of the primary areas assessed by the NIHSS includes visual function, which looks at the patient’s ability to perceive visual stimuli and can indicate the extent of visual loss due to stroke. Language deficits are also evaluated, as this aspect is crucial for understanding how stroke affects communication abilities. Lastly, the level of consciousness is a vital component of the NIHSS, helping medical professionals gauge the patient's overall neurological state and responsiveness.

The other options do not align with the focus of the NIHSS. Assessing heart rhythm, blood pressure, and respiratory rate pertains to general physiological monitoring rather than a specific neurological assessment. Additionally, evaluation of pupil reaction, skin condition, and temperature focuses more on general physical examination and assessment rather than the specific neurologic impairments addressed by the NIHSS. Finally, while pain level, mobility, and coordination are important clinical aspects, they do not fall under the specific components measured by the NIHSS for determining the effects of a stroke. Overall, option A is
