Trivia Questions Quiz On Cranial Nerve Examination! - Quiz

Cranial nerves are those that originate from the brain and are charged with bringing information from the sensory organs. Do you know how to identify them and their functions? Can you also detect any issues within them? These trivia questions quiz will help see how good you are when it comes to cranial nerve examination in different scenarios involving patients.


Questions and Answers
  • 1. 
    Type in the correct cranial nerve. Assess vision in each eye with a Snellen chart.
  • 2. 
    Type in the correct cranial nerve. Assessment:  Assess the ability to feel light, dull, and sharp sensations on the face. With the patient’s eyes closed, check whether sensation is the same on both sides of the face. Stroke the cheek with a wisp of cotton for light touch, with a closed safety pin for dull touch, and with a tongue depressor for sharp touch. If the sharp point of a safety pin is used to assess sharp touch, avoid scratching the surface of the skin and discard the pin after use. Assess the corneal reflex by touching the corneal surface with a wisp of sterile cotton. The reflex may be absent or decreased in patients who wear contact lenses.
  • 3. 
    Assessment: Assess extraocular movements by asking the patient to follow your finger as you write an H in the air. Assess PERRL (pupils equal, round, and reactive to light) by covering one eye at a time and shining a bright light directly into the uncovered eye using a penlight or the ophthalmoscope. Assess for ptosis (drooping eyelids).
