N316B Exam 2 Questions With 100% Verified
Answers!!
two types of stroke
- common intervention
Ischemic - caused by embolus or thrombus (clot) in cerebral artery which blocks blood flow and
oxygen, resulting in cell death
Hemorrhagic - rupture and hemorrhage of cerebral artery (ruptured aneurysm or trauma),
resulting in compression of brain cells which decreases blood flow
Common intervention, must be administered within first 4 hours: Recombinant tissue-type
plasminogen activator (rt-PA) or tPA
What kind of stroke would be indicated when a CT scan identifies bleeding in a specific
area of the brain?
Intracranial hemorrhage (hemorrhagic stroke)
If a patient experiencing an ischemic stroke does not respond to thrombolysis, what is the
next option?
Thrombectomy
Huntington's disease
A human genetic disease caused by a dominant allele; characterized by uncontrollable body
movements and degeneration of the nervous system; usually fatal 10 to 20 years after the onset
of symptoms.
- athetosis
athetosis
- what is it
- what is it associated with
, bizarre, slow, twisting, writhing movement, resembling a snake or worm
- huntingtons disease
Parkinson's disease
- common treatment
PD is a disorder where there is degeneration of basal ganglia. There is not enough dopamine and
tremors are caused by the acetylcholine without dopamine to counteract them. Can manifest as
stiff/mask-like facial expression, tremors, muscle rigidity, bradykinesia, loss of postural reflexes,
loss of arm swing
- anticholinergic treatment
What neurotransmitter is deficient with this disorder (Parkinson's disease)?
dopamine
What are the side effects of anticholinergic treatment
Confusion, agitation, delirium, n/v There are some other uncomfortable side effects of the
agent.[1] [2] - Dry mouth, blurry vision, photophobia, constipation, urinary retention
myasthenia gravis
a chronic autoimmune disease that affects the neuromuscular junction and produces serious
weakness of voluntary muscles
- loss of Ach
myasthenia gravis diagnostic tests
Endrophonium (Tensilon) Testing - acetylcholinesterase inhibitor
-- Improves neuromuscular weakness; allows Ach to remain in synapses longer
➢ Serum Ach receptor antibodies
➢ EMG (electromyography) This is uncomfortable
generalized seizures 4
Absence
Atonic
