A patient is unable to differentiate between sharp and dull stimulation to both sides of her face. The nurse suspects:
 
  a. Bell palsy.
  b. Damage to the trigeminal nerve.
  c. Frostbite with resultant paresthesia to the cheeks.
  d. Scleroderma.

Question 2

The nurse notices that a patient's palpebral fissures are not symmetric. On examination, the nurse may find that damage has occurred to which cranial nerve (CN)?
 
  a. III
  b. V
  c. VII
  d. VIII

Answer to Question 1

ANS: B
Facial sensations of pain or touch are mediated by CN V, which is the trigeminal nerve. Bell palsy is associated with CN VII damage. Frostbite and scleroderma are not associated with this problem.

Answer to Question 2

ANS: C
Facial muscles are mediated by CN VII; asymmetry of palpebral fissures may be attributable to damage to CN VII (Bell palsy).
