NEUROLOGICAL SYSTEM AND DISORDER

CRISIS 5
Neurological system and disorders

1.        A patient arrived in the ER with a head injury. She is unconscious. You and a fellow nurse are the only staff members near the patient. He begins to criticize the attending physician and suggest that a different physician should care for this patient. What is the best response?

c.       Ask the nurse why he has such feelings.
d.       Simply nod your head in agreement.
2.       Your patient has unilateral facial paralysis and is unable to close his right eye. He is diagnosed with Bell’s palsy. He asks you if there is any special care required for his eye. What is the best response?

b.       Wear sunglasses.
c.       Increase fluid intake to prevent dryness of the eye.
d.      Yes, you’ll need to instill artificial teardrops and use an eye patch.
3.       A new patient arrived in your unit. He has been diagnosed with a brain tumor. You are told that the patient is unable to speak. Based on this sign, where do you expect the tumor is located?
a.       Frontal lobe.

c.       The aneurysm must have developed since his physical.
