Final answer:
PMS in all extremities and pupillary response are assessed during a neurological exam, particularly when symptoms suggest a neurological issue or in emergency settings.
Step-by-step explanation:
Assessing PMS (pulse, motor, sensory functions) in all extremities and checking a pupillary response are typically part of a neurological exam, which may be performed when a patient presents with symptoms such as weakness, numbness, or other abnormal sensations that suggest a potential issue with the nervous system.
This can include situations where a patient has had a possible stroke, head injury, or any other medical condition that could affect neurological function. In the context provided, a student would learn to perform these assessments when neurological deficits are evident or suspected, particularly in emergency settings to quickly determine the extent and location of a possible neurological impairment.
The mentioned symptoms of pins and needles and trouble feeling sensations on one side of the body might indicate a neurological issue, thus necessitating these assessments before further steps like a CT scan or administering aspirin therapy to prevent clotting.
