Which assessment would help determine if a patient has a neurological deficit?

Assessing strength and sensation in extremities is crucial in determining whether a patient has a neurological deficit. This assessment evaluates the functioning of the peripheral and central nervous systems. By checking muscle strength, a nurse can identify any weakness that may suggest nerve or brain damage. Additionally, testing sensation helps to determine if there are any impairments in sensory pathways, which can indicate neurological issues.

Other assessments, such as checking blood pressure, conducting a vision test, or measuring heart rate, provide valuable information about a patient's overall health but do not directly assess neurological function or deficits. For instance, while a vision test may reveal visual impairments, it won't necessarily address other aspects of neurological assessment, such as motor control or sensory perception. Therefore, the strength and sensation evaluation is the most accurate way to identify potential neurological deficits.
