8. Common symptoms of MS do NOT
include:

vision and trouble seeing the
board in school

fatigue, increased thirst, and
frequent urination

puncture, MRI

MRI

included in the responsibilities of a
home health nurse?
a. Administer medications
b. Identify clinical problems
c. Provide client care in home
d. Teach family and caregivers
e. All of the above
17. Demyelination of nerves in MS is
caused by:
a. Attack of the body’s immune
system with subsequent
inflammation
b. Bacterial toxins
c. Elevated serum protein levels
d. Slowing of nerve impulses
e. All of the above
