Final answer:
For suspected Amaurosis Fugax, a carotid ultrasound is the correct test. It detects potential obstructions in carotid arteries that could lead to ischemic conditions affecting vision. Sensory deficits are typically assessed using a tuning fork in a neurological examination.
Step-by-step explanation:
If a patient is suspected of having Amaurosis Fugax, which is a transient visual disturbance that serves as a warning sign of a potential stroke, the appropriate test to conduct would be a carotid ultrasound. This test helps to evaluate the carotid arteries that supply the brain with blood to detect any possible obstructions or narrowing that could cause ischemic events leading to vision loss. An electroencephalogram (EEG) may be used to assess brain activity in cases of seizures, audiometry for hearing evaluations, and a chest X-ray could be meaningful if there are suspected issues in the chest.
For a patient experiencing sensory deficits, the appropriate neurological examination would be: placing a 128 Hz tuning fork over a bone to assess sensory function through vibration perception. A reflex hammer may be used for assessing reflexes, and following a target or commands could help to evaluate motor and cognitive functions respectively. In pregnant patients, ultrasounds are considered the safest imaging study.
