Question

all of the following are signs and symptoms of someone having vertebrobasilar ischemia/insufficiency (vbi), except?
a) diplopia
b) numbness, bilateral
c) ataxia
d) dizziness/vertigo

Explanation:

Diplopia (double - vision), bilateral numbness, ataxia, and dizziness/vertigo are all common signs and symptoms of Vertebrobasilar Ischemia/insufficiency (VBI) as it affects blood - flow to the brainstem and cerebellum. There is no option here that is not a symptom. However, if we assume there is an error in the question setup and we need to pick one that might be less typical in some cases, there is no such clear - cut non - symptom among these. But if we go by pure knowledge of VBI symptoms, all are well - known symptoms.

Answer:

There is no correct "except" option among a) Diplopia, b) Numbness, bilateral, c) Ataxia, d) Dizziness/vertigo as all are common VBI symptoms.
