It all depends on what nerve and what it is positive for.
The corneal reflex will not test for injuries to the facial nerve (cranial nerve VII) as it primarily assesses the integrity of the trigeminal nerve (cranial nerve V) and the ophthalmic branch of the trigeminal nerve.
It entirely depends on which cranial nerve you are testing, having coffee in an unlabeled cup and blinding folding th pt is one test, tracing the pts face with a cotton tipped applicator is another test. There is a test for each cranial nerve.
Well you see bryan, the nerve that is right below the hair folical happens to be worth 12 cents.
The abducens nerve (cranial nerve VI) is tested by examining lateral eye movement. Ask the patient to look laterally towards each side to assess for any weakness or limited movement of the eye. Additionally, performing the "H test" can help evaluate if there is any dysfunction of the abducens nerve.
corneal reflex. It involves touching the cornea with a wisp of cotton, which should trigger a blinking response mediated by the trigeminal nerve, specifically the ophthalmic branch. This reflex assesses the sensory function of the trigeminal nerve in detecting sensations on the cornea.

Yes. You should do a blood test by your doctor.
Vistaril (often misspelled as vistoril) is a hydroxyzine and not a benzodiazepine. It should not make you test positive for benzos. AskDocWeb.com
No, it should not affect this test.
Definitely. It is a good way to assess cranial nerve function which is a standard part of a neurologic exam routine in most pre-purchase exams
