LUMBAR PUNCTURE......?
|
~WHY...? IS PERFORMED TO OBTAIN SAMPLES OF CSF FROM THE SUBARACHNOID SPACE FOR LAB EXAM AND TO MEASURE CSF PRESSURE: NORMALLY IS 1-15MM/HG; PRESSURE OVER 200mm H20 IS CONSIDERED ABNORMAL.
|
|
|
WHAT ARE SOME OTHER REASONS TO PERFORM A LUMBAR PUNCTURE?
|
1)inject a drug - intrathecal injection
2) to withdraw CSF for the relief of intra-cranial pressure 3) to inject air, gas, or dye neuro DX |
|
|
What procedure is used for lumbar puncture?
|
Strict aeseptic technique
|
|
|
Contrast studies ...?
|
Include: cerebral angiography,w/c detects distortion of creebral arteries and veins, indicatating an aneurysm, a tumor, or other vascular abnormality.
|
|
|
Procedure for contrast studies....?
|
~a radiopaque dye is injected into the right or left carotid artery,brachial artery, or the femoral artery.
`A rapid sequence of radiographs is taken as the dye circulates through the cerebrial arteries and veins. |
|
|
For a myelogram...?
|
~a radiopaque substance is injected into the spinal cord by means of LUMBAR PUNCTURE
~XRAYS ARE TAKEN TO DEMONSTRATE ABNORMALITIES OF THE SPINAL CANAL SUCH AS TUMORS OR A RUPTURED INTERVERTEBRAL DISK. |
|
|
ELECTROENCEPHALOGRAM...?
|
~EEG RECORDS ELECTRICAL IMPULSES GENERATED BY THE BRAIN. eLECTRODES ARE PLACED ON THE SCALP AND ELECTRICAL ACTIVITY IS RECORDED ON A GRAPH.
|
|
|
FOR EEG WHAT TEST PREP IS DONE?
|
WASH THE PATIENT'S HAIR.
|
|
|
IF A PATIENT HAS A PACEMAKER, OR ANY METAL IN THEIR BODY, I.E., HIP PINS, CAN THEY GET AN EEG?
|
nO, DAAH.
|
|
|
wHY WOULD A PATIENT NEEED A BRAIN SCAN?
|
~TUMORS, HEMATOMAS IN OR AROUND THE BRAIN, CEREBRAL ABSESSES, CEREBRAL INFARCTIONS, OR DISPLACED VENTRICLES.
|
|
|
PROCEDURE FOR BRAIN SCAN...?
|
A RADIOACTIVE MATERIAL IS INJECTED BEFORE THE PROCEDURE, THE LENGTH OF THE PROCEDURE VARIES FROM A VEW MINUTES TO ONE HOUR. CT SCANS AND MRI ARE REPLACING THIS PROCEDURE.
|
|
|
ELECTROMYOGRAPHY...?
|
(EMG) STUDIES CHANGES IN THE ELECTRICAL POTENTIAL IN MUSCLES AND THE NERVES SUPPLYING THE MUSCLES.
~NEEDLE ELECTRODES ARE PLACED INTO ONE OR MORE SKELETAL MUSCLES AND THE RESULTS RECORDED ON AN OSCILLOSCOPE. tHIS TEST IS USEFUL IN DETERMINING THE PRESENCE OF NEUROMUSCULAR DISORDERS. |
|
|
NERVE CONDUCTION STUDIES...?
|
mEASURE THE SPEED WITH WHICH NERVE IMPULSES TRAVEL ALONG A PERIPHERAL NERVE FIBER WHEN A SPECIFIC NEREVE IS ELECTRICALLY STIMULATED.
~This test aids in DX of NERVE INJURY and COMPRESSION, or NEUROLOGIC DISORDERS affecting PERIPHERAL NERVES. |
|
|
ECHOENCEPHALOGRAPHY...?
|
~An echoencephalogram is an ULTRASOUND EXAMINATION OF THE STRUCTURES OF THE BRAIN.
~tHIS PX is performed to detect ABNORMALITIES IN THE VENTRICLES and the location of INTRACRANIAL BLEEDING. |
|
|
Position for lumbar puncture...?
|
~Modified Trendlenderg
|
|
|
Following a lumbar puncture, a client asked to ambulate to the restroom. Is this appropriate. If not, why?
|
~Explain the client must lie flat and explain why.
He will be in orbit with a major headache and want to kill the nurse. |
|
|
An ICU Nurse is assessing a client's level of LOC, she finds notes the client awakens when his name is called and then quickly drifts off when asked questions. When documenting this client's LOC, what should the nurse document...?
|
Somnolent/lethaqrgic
