Bell's Palsy By Rnpedia.Com

1. The nurse is aware that Bell's palsy affects which cranial nerve?

2nd CN (Optic)

3rd CN (Occulomotor)

4th CN (Trochlear)

7th CN (Facial)

Bells’ palsy is the paralysis of the motor component of the 7th caranial nerve, resulting in facial sag, inability to close the eyelid or the mouth, drooling, flat nasolabial fold and loss of taste on the affected side of the face.

Explanation

Bells’ palsy is the paralysis of the motor component of the 7th caranial nerve, resulting in facial sag, inability to close the eyelid or the mouth, drooling, flat nasolabial fold and loss of taste on the affected side of the face.

2. Bell's palsy is a disorder of which cranial nerve?

Facial (VII)

Trigeminal (V)

Vestibulocochlear (VIII)

Vagus (X)

Bell’s palsy is characterized by facial dysfunction, weakness, and paralysis. Trigeminal neuralgia is a disorder of the trigeminal nerve and causes facial pain.Meniere’s syndrome is a disorder of the vestibulocochlear nerve. Guillain-Barre syndrome is a disorder of the vagus nerve.

3. Bell's palsy is a form of facial paralysis caused by a dysfunction of the 8th cranial nerve.

True

False

Bell's palsy results from a dysfunction of the 7th or facial cranial nerve.

Explanation

Bell's palsy results from a dysfunction of the 7th or facial cranial nerve.

4. Failure of the eye to close properly can occur, which may result in damage to the cornea.

True

False

To try and avoid corneal damage the lid can be taped shut at night and eye drops used to lubricate the eye.

Explanation

To try and avoid corneal damage the lid can be taped shut at night and eye drops used to lubricate the eye.

5. Oral steroids may help reduce the symptoms of a Bell's Palsy.

True

False

Oral steroids can improve outcome but need to be given early after the onset of symptoms.

Explanation

Oral steroids can improve outcome but need to be given early after the onset of symptoms.

6. A male client with Bell's palsy asks the nurse what has caused this problem. The nurse's response is based on an understanding that the cause is:

Unknown, but possibly includes ischemia, viral infection, or an autoimmune problem

Unknown, but possibly includes long-term tissue malnutrition and cellular hypoxia

Primary genetic in origin, triggered by exposure to meningitis

Primarily genetic in origin, triggered by exposure to neurotoxins

Bell’s palsy is a one-sided facial paralysis from compression of the facial nerve. The exact cause is unknown, but may include vascular ischemia, infection, exposure to viruses such as herpes zoster or herpes simplex, autoimmune disease, or a combination of these factors.

7. Bell's palsy can be associated with arm and leg weakness and difficulty finding the right words.

True

False

These signs indicate a stroke and if present the patient needs urgent medical attention.

Explanation

These signs indicate a stroke and if present the patient needs urgent medical attention.

8. The nurse has given the male client with Bell's palsy instructions on preserving muscle tone in the face and preventing denervation. The nurse determines that the client needs additional information if the client states that he or she will:

Exposure to cold and drafts

Massage the face with a gentle upward motion

Perform facial exercises

Wrinkle the forehead, blow out the cheeks, and whistle

Prevention of muscle atrophy with Bell’s palsy is accomplished with facial massage, facial exercises, and electrical stimulation of the nerves. Exposure to cold or drafts is avoided. Local application of heat to the face may improve blood flow and provide comfort.

9. Bilateral Bell's palsy can occur.

True

False

This will result in total facial paralysis but it is very rare.

Explanation

This will result in total facial paralysis but it is very rare.

10. Which of the following diseases has not been directly linked with Bell's palsy?

AIDS

Diabetes

Lyme disease

Alzheimer's disease

Bell's palsy is a condition that causes sudden weakness or paralysis of the muscles on one side of the face. It is believed to be caused by inflammation of the facial nerve, but the exact cause is still unknown. While AIDS, diabetes, and Lyme disease have been directly linked with Bell's palsy, there is no direct link between Bell's palsy and Alzheimer's disease. Alzheimer's disease is a progressive brain disorder that affects memory, thinking, and behavior, and it does not typically cause facial paralysis.

11. When the nurse performs a neurologic assessment on Anne Jones, her pupils are dilated and don't respond to light.

Glaucoma

Damage to the third cranial nerve

Damage to the lumbar spine

Bell’s palsy

The third cranial nerve (oculomotor) is responsible for pupil constriction. When there is damage to the nerve, the pupils remain dilated and don’t respond to light. Glaucoma, lumbar spine injury, and Bell’s palsy won’t affect pupil constriction.
