Final answer:
The baseline neurologic and sensory assessment determines the current level of function in an older adult, to compare with future assessments and plan care, including rehabilitation. For impaired sensory functions, a neurologist might use a 128 Hz tuning fork test.
Step-by-step explanation:
The purpose of a baseline neurologic and sensory assessment in an older adult patient admitted to a long-term care facility is A) Determine a level of function for later. This assessment allows healthcare providers to establish a patient's current level of neurologic and sensory function, which can be used as a reference point for future assessments. This evaluation helps in identifying any changes or declines in function over time and assists in planning for care needs, including potential rehabilitation efforts.
If a patient had impaired sensory functions, the exam a neurologist might perform according to the OpenStax College resource includes placing a 128 Hz tuning fork over a bone to test for sensory responses and vibrations. This test helps in identifying the sensory impairment and determining the severity and specific nature of the condition.
