Med Surg 2: Neuro, Spinal/Head Injuries, Thyroid & Adrenal Flashcards
What diagnostic exam is usually performed first for an acute stroke?
CT without contrast: to rule out acute bleed–need to determine if stroke is hemorrhagic or ischemic.
Aphasia that affects speech production; result of an infarction in the ___ lobe of brain
Broca’s (expressive or motor); frontal
Aniscoria=
Unequal pupils
What is a therapeutic Dilantin level?
10-20
What is most often the first sign of increased ICP?
Change in LOC.
How do you treat a spinal headache after an LP?
Lay flat and giving fluids/drink with straw/caffeine; May have to do Blood Patch if it lasts more than 24 hours–draw blood out of arm and inject blood into hole to seal it off–works almost immediately
Clinical Manifestations of Right side stroke damage:
–Hemiplegia/hemiparesis (weakness/paralysis on one side) --left side. –Neglect-left side –Spacial- perceptual deficits –Will deny or minimize problems –Short attention span *Impulsive: safety risk--aren't cautious –Impaired judgement
•Generalized findings of stroke no matter what area
–HA
-Increased ICP: often with Hemmorhagic stroke because blood takes up space
–Vomiting
–Seizures
–Mental status changes
What is the nursing management pre-procedure and during an EEG?
•Pre-procedure
–Shampoo without conditioner: makes it more slippery
–No caffeine 24-48 hours: alters electrical activity
–Some meds d/cd for 24-48 hours: CNS depressants
–Some are sleep-deprived
•During
–Takes approximately 1 hour
-Patient needs to remain still
–Evoked potential – flashing lights, buzzers, etc
•For brain stem injury and coma assessment
Clinical Manifestations of Left sided Stroke damage:
–Hemiplegia- which side? Right. –Aphasia- sometimes global –Dysarthria: able to express, but words don't come out clearly--garbled, slurred –Cautious –Depression/anxiety –Impaired comprehension •Language and math –Memory problems with language
•Generalized findings of stroke no matter what area
–HA
-Increased ICP: often with Hemmorhagic stroke because blood takes up space
–Vomiting
–Seizures
–Mental status changes
What are some things that can lead to seizure other than epilepsy?
–ETOH withdrawal –Electrolyte imbalances –Hypoxia –Fever & dehydration –Hypoglycemia –Drug intoxication –Poisoning –Tumors –Traumatic brain injury
Mydriasis=
pupil dilation
Manifestations of PD?
•Unilateral Tremors –pill rolling movements: movement of fingers •Rigidity •Flexed neck, trunk, limbs •Bradykinesia –Shuffled gait –Akinesia – or freezing movements •Loss of postural reflexes *Problems with chewing food •Dysarthria: difficulty articulating clearly
Hypertensive Crisis = higher than ___ or higher than ____

Tetraplegia occurs from ___ cord injuries.
cervical
What two “Signs” are used to assess for meningitis?
Kernig’s Sign (patient in supine, with hip flexed at 90 degrees, knee is unable to be extended); Brudzinski’s Sign (patient in supine, when lifting up head, it causes flexion of both legs and thighs)
Hemiparesis=
weakness on one side of the body
What are some potential complications of Autonomic Dysreflexia?
Seizures, cerebral hemorrhage, MI, death
What is the POE for Meningitis?
Nasopharynx
Homonymous Hemianopia =
A visual loss in the same half of the visual field of each eye so the pt has only half of normal vision
What is a common osmotic diuretic given for increased ICP?
Mannitol
What should the HOB be at with someone with increased ICP?
MD will probably set parameters at about 30 degrees.
American Stroke Association recommendations to call 9-1-1 if :
•Call 9-1-1 if have 1 or more:
–Sudden numbness or weakness of face, arm, or leg, especially on one side of the body
–Sudden confusion, trouble speaking or understanding
–Sudden trouble seeing in one or both eyes
–Sudden trouble walking, dizziness, loss of balance or coordination
–Sudden severe headache with no known cause
Etiology of Parkinson’s?
–Environmental and genetic
- Long-term exposure to phenothiazines (Thorazine, Compazine)
- Carbon monoxide/copper miners or mercury poisoning
What is Cushing’s Triad (response)?
A late response to increased ICP: bradycardia, systolic hypertension, and widening pulse pressure; Alterations in the respiratory pattern also accompany Cushing’s Triad (ie Cheyne-Stokes respirations)
