Q

Speech comprehension
They do word salad
For pt w/ Wernicke’s aphasia – ACT OUT WORDS – DRAW WORDS
•Individuals with Wernicke’s aphasia speak in long, uninterrupted sentences
• Reading ability is diminished, and although writing ability is retained, what is written may be abnormal
• Speech is preserved but language content is incorrect
o This may vary from the insertion of a few incorrect or nonexistent words to a profuse outpouring of jargon.

A

Motor function

58
Q

Measures blood flow
Tissue composition
Brain metabolism
Excellent for picking up lesions and brain tumors.
Radioactive tracer injected or inhaled which crosses blood brain barrier, and combines with electrons in the brain.
Patient teaching:
o No ETOH, no smoking, no caffeine prior to test.
o Pt may get dizzy or light headed
o Headaches when inhaling isotope
o After test is complete be sure pt voids to get rid of radioactive substance in body.

A

PET SCAN

59
Q

Used to pick up soft tissue abnormalities such as changes within the cells, tumors, and necrotic tissue, degenerative changes w/in brain.
o Patient teaching:
o Pt. may experience claustrophobia,
o Remove anything metal than may be on or in person, such as IUD’s, hearing aids.(pt’s w/ metal prostesis such as hip or shoulder replacements are not candidates for this test.) Mri tech needs to know if pt has pacemaker, artifical heart valve.
▪ Empty bladder before test

A

MRI

60
Q

• For pt who have stroke
• Tia – transient ischemic attack
• What angina is to a heart attack, TIA is to stroke
• We will study the blood flow going to the brain
• Estimated that when PP (pulse pressure) get to 60 – 70 their arteries are 50% blocked by 80: 60 to 70% blocked
• It is risk for stroke
• In this case we will monitor blood going into the brain which can ID stroke
Doppler – non-invasive – used to detect arterial stenosis, occlusion or plaque.
o Ultrasound waves are used to evaluate carotid artery blood flow.

A

Carotid Doppler

61
Q

o Malformation in the connection between arteries and veins
o Is congenital/birth defect and run in families
o 2-3 out of 10 are AV malformation and Aneurism
o Usually asymptomatic
o If BP is kept within healthy range Av malformation will not cause any trouble at all for duration of life span.

A

AV malformation:

62
Q

• Inject dye
• Look at blood circulation of blood In brain
o Patient needs to be hydrated
o Empty bladder
o A lot of swelling and discomfort – use ice bags
o Check pulses frequently –ESP DISTAL – check for adequate circulation to extremities

A

Cerebral angiography

63
Q

very invasive
o Pt is in a side lying fetal position
o Insert long needle in between L3 & L4 or L4 & L5 – subarachnoid space
o DO NOT DO with ICP – can cause herniation of brain into brain stem
o Takes out CSF to be evaluated (CSF should be clear and colorless, if bloody can be contusion or hemorrhage in brain or spinal cord.)
o To administer medication, anesthesia
o Strict aseptic technique
o Pt teaching:
May develop a spinal headache and may last for several days, so patient should lie flat as much as possible

A

Spinal tap

64
Q

The lumbar puncture needle is a very long needle
• It is possible that CSF will continue to drain out through opening of syringe
• We will do what is called epidural patch – take pt blood and inject it into hole to seal it off.
• It is not a foreign object - it is their own blood - it will seal off puncture so CSF will not leak out.

A

Spinal tap complications

65
Q

Lay pt in flat position – which prevents spinal headache
• Give lots of fluids since pt needs to rebuild CSF
• Check epidural patch dressing to make sure its not draining
o Examine carefully
• Treat spinal headache
o Usually top of forehead will be throbbing when sitting or standing
• Remind Dr. not to remove too much fluid.
• Pt with increase ICP CAN’T get a lumbar puncture
Most important NI is to assess pt for s/s of increased ICP prior to lumbar puncture

A

Nursing interventions for spinal tap

66
Q

• Use it with pt who has spinal cord tumor (MRI would give better view)
• Inject Pt with dye
o Water soluble dye
o Hydrate pt to get dye out of body
• Most procedures with punctures cause impaired skin integrity b/c pt received injection
o There is also a risk for meningitis

A

Myelography
