Q

Spinal Shock (cord damage) what may occur?

A
  • lose motor, sensory and autonomic activity below the level of injury may result in decrease in BP.

  • Lay client in FETAL position, local anesthetic, consent

(Fetal position opens up spinal vertebrae for tap;; stay still to avoid injury.)

Post test: lay flat for 2 hrs, encourage fluids

25
Should you give narcotics to neuro patients?
-No,
26
Multiple Sclerosis med tx

- Reattaches sclera to retina - Post op: BED REST/ LIMITED HEAD MOVEMENT, check with dr about activity
28
s/s of retinal detachment
visual field loss and the appearence of flashing lights
29
Manitol (for ICP)
Osmotic Diuretic, pulls fluid from the third space into vascular space then diuresis the pt, fliters through kidneys. CHECK RENAL FUNCTION AND ELETROLYTES
30
Decadron (FOR icp)
-corticosteroid- stabilizes capillary membrane permiability (leaky) doesnt leak to 3rd space in brain
31
-Ear drops
-WARM them before administration
32
Cushings Triad
-**Widening Pulse Pressure,** respirations, bradycardia
33
s/s Menieres
- vertigo, sensorineural loss, tinnitus - avoid getting up suddenly
34
Injury above C6, assess what?
-Respirations and need for ventilator because of weakness in intercostal muscles
35
Autonomic Dyspreflexia
- caused by visceral stimulations (visceral organs include bowel, bladder, and skin) - urinary retention= straight cath - skin= remove clothes Pt develops increases HTN, LOC changes, pounding headache, goosebumps, stroke if left untx
36
Normal IntraOcular Pressure
10-21 mm
37
Pt has functional blindness, how should nurse plan the care?
functional blindness 20/200 - check visual acquity - orient to environment - Promote safety
38
Pt has pain in eye after post op cataract surgery
-REPORT to dr. Could be infection, hemorrhage, or increase IOP.
39
Photopsia, Floaters, and loss of peripheral vision are clinical manifestations of
-retinal detachment
40
Increased IOP and peripheral vision loss indicate
Glaucoma
41
Betoptic, Timoptic, Diamox (beta blockers)
Decreases aqueous humor production which then decreases IOP.
42
Pilocarpine
- Constricts pupil - increases outflow of aqueous humor
43
When patient has clear discharge from the nose or ear....
do glucose test to detect CSF leakage.
44
bells palsy
Cranial 7. - Antivirals. - Gentle upward massage of face, use heat, avoid cold.
45
ALS (Lou Gherigs)
- 2-5 YRS after prognosis, terrible prognosis. - check gag reflex - end stage- pt on vent or hospice because respiratory system affected. - Rilutek- drug slows progression.
46
How do you know that Sinemet (Levadopa/Carpadopa) is no more effective?
-bradykinesia, tremors, and shuffling gait return
47
What to teach pt taking Dilantin? (Anti-seizure) Maintainence drug for seizures normal level 10-20
-do oral care, and have regular visits with dentist to check for gingival hyperplasia.
48
During seizure what do you document?
-What pt was doing before seizure, what part of body was affected, and where twitching started first.
49
As patient is having seizure..
- turn them on their sside to prevent aspiration, and do not put anything in their mouth. - loosen any restrictive clothing. - do not restrain
50
Pt has brain tumor what symptom will they most likely experience?
-Early morning headache.
51
ICP- prevent increase
- treat cause - elevate HOB30 degress! - fluid restrictions - Manitol, Decadron, Diuretics - Seizure precautions ( padded bed rails, dim lights, decrease stimuli, let them rest. )
52
Open Angle Glaucoma
\>50
53
Labs for pt on decadron
hyperglycemia, hyponatremia, hypokalemia Pt with Na of 129 would be most concern to RN
54
Pt presents with eye injury
-do head to toe assessment
55
Pt with dysplasia, what do you check before they eat?
-gag reflex
56
First symptom of cataracts
-nighttime glare (probs driving at night)
57
First thing people complain of with Multiple Sclerosis?
- optic neuritis (blurred vision) - falls
58
Epidural Hemorrhage
- EMERGENCY SITUATION:collection of blood btwn skull and dura - Always go to surgery - Epidural bleed is arterial bleed
59
Subdural Hemorrhage
- Venous bleed - depends how quickly the bleed is. if slow, or stopping, the neurosurgeon will let it absorb itself... - family can sometimes miss the symptoms
60
Mestinon
- Treatment for Myasthenia Gravis - take p.o on schedule with meals
61
Neurontin
- given for seizures, safer for elderly - come back to check serum levels
62
Petit mal seizure
- children - blinking, brief staring spell, rolling of eyes - 5-10 seconds - no post ictal symptoms - do not lose conciousness - often misdiagnosed.
63
Midriatics
-Dilate the pupil
64
Post op eye surgery are patients encouraged to cough and deep breath?
- NO! - avoid coughing, sneezing, cant drive 4-6 weeks, avoid anything that increases IOP. sex, bending, lifting
65
Bilateral eye patching should be done in tauma or in possible retinal detachment because
-eyes are consensual, they move together goal is to prevent further ischemia to retina
66
Humonymous Hermianopsia
-blindness on same side in both eyes , put everything in their line of vision!!!! approach from unaffected side and manually scan environment!
