Flashcards in Med surg III Neuro Deck (43):
1

autonomic dysreflexia

develops in spinal cord injuries, life threatening, acute, uncontrolled hypertension, sudden and severe headache, bradycardia

2

aphasia

can't communicate, express or understand language, written and verbal...typically occurs after stroke or brain injury

3

aphagia

inability to swallow

4

apraxia

inability to perform tasks (typically speech) or movements when asked, even though they can understand the request, are willing to do it, the muscles needed to do it are functioning, and it is something that they could do before. Usually result of stroke or brain injury

5

ataxia

uncoordinated movement, jerky, unsteady gait or to and fro motion of the middle of the body

6

anopsia

suppression of vision in one area only

7

diplopia

double vision

8

agnosia

loss of ability to detect sensory stimuli, such as sounds or images (can be auditory, gustatory, olfactory, tactile, and visual) inability to use an object correctly

9

dysphagia

difficulty swallowing

10

endocarderectomy

surgical removal of plaque from an artery that has become narrowed or blocked

11

Kernig's sign

indicates the presence of meningitis...patient can't extend the leg at the knee when the thigh is flexed because of stiffness in the hamstrings (back pain and resistance to straightening is a positive Kernig's sign)

12

postictal

recovery period after a seizure (mimics a stroke)

13

trigeminal neuraglia

chronic pain condition that affects the trigeminal nerve, which carries sensation from your face to your brain.

14

Glasgow Coma Scale

used to describe the level of consciousness and cognition, measures eye opening, verbal response, and motor response

15

Right-sided stroke symptoms

often unaware of any deficits, may be disoriented to time and place, personality changes such as poor impulse control and poor judgement, impaired sense of humor, constant smiling, some hearing loss

16

Left-sided stroke symptoms

speech, language, and writing deficits, memory deficits

17

hemiparesis

weakness on one side of the body

18

hemiplegia

paralysis on one side of the body

19

when is patient with head injury at risk for increased ICP

hours or a few days after the event

20

drug most commonly used to treat ICP

mannitol, an osmotic diuretic. most effective when given in boluses rather than continuous infusion

21

drug used as adjunct therapy for ICP

furosemide, a loop diuretic, to reduce the incidence of rebound from mannitol

22

goal level for ICP

less than 20 mm Hg

23

goal level for CPP

above 70 mm Hg

24

which patients should not receive mannitol

acute kidney injury patients

25

Cushing's triad

late sign of ^ ICP (systolic hypertension, bradycardia, and irregular respirations). often signifies irreversible damage

26

what can result from a tumor in cerebellum

falls, because this controls posture and space

27

what can result from stroke affecting frontal lobes

can change a person's behavior/personality

28

most common adverse effect of lumbar puncture

Headache, lie flat for 1 - 2 hours after procedure, quiet and dark room, analgesics for pain

29

irregular breathing pattern is associated with damage to?

brain stem

30

signs and symptoms of ^ICP

Change in LOC, slow, irregular respirations, ^ BP, decreased pulse

31

positioning of patient with ^ ICP

neutral position, head midline in stable position, do not leave patient on their side, elevate HOB

32

Romberg test

inability of patient to maintain body balance when eyes are shut and feet are close together (positive if pt sways and falls)

33

why do you need to check glucose

hypoglycemia mimics stroke

34

Central nervous system is?

Brain and spinal cord

35

Frontal lobes control?

Personality, behavior, higher intellectual functions

36

Parietal lobe controls?

Recognition of sizes, shapes, voluntary movement

37

Temporal lobe controls?

Senses, spoken word

38

Occipital lobe controls?

Vision, understanding what you are seeing

39

What are the neurotransmitters?

Acetylcholine, dopamine, serotonin, epinephrine

40

Purpose of CSf?

Provide cushion

41

Hypothalamus controls?

Metabolism, growth, sexual maturity, body temp, rate, blood pressure, sleep

42

Thalamus controls?

Emotional responses

43

Cerebellum controls?

Posture, space-prevents falls
