A

Caused by discrete, temporary metabolic abnormality or height fever and does not means a dx of epilepsy, unless they reoccur and become a pattern

29
Q

Focal onset

A

Can start in one area or group of cells in the brain - person can be awake or impolite awareness - may be confused

30
Q

Generalized onset

A

Affects both sides of the brain at the time time, may be Tonic/clonic or atonic

31
Q

Unknown onset

A

Onset not witnessed

32
Q

Tonic

A

Sudden stiffening and contraction of the muscle

33
Q

Clonic

A

Rhythmic twitching and jerking of one or several muscles

34
Q

Tonic - clonic

A

Combination fo both types and typical in generalizes seizure

35
Q

Seizure threshold lowering factors

A
Decreased sleep
Increased ETOH
Physical / emotional stress
Flashing lights
Fever
Hormones
Drug use
36
Q

Seizure medications

A

Strive for monotherapy

  • Consult Neuro
  • therapeutic ranges of rugs, CBC and LFT’s
37
Q

Dilantin - side effects

A

Gingival hyperplasia

38
Q

Meningitis

A

Inflammation of Brian and spine cord meme brain

Acute or subacute

Viral or bacterial

39
Q

Meningitis - presentation

A

Fever, headache, stiff neck, n/v/ photophobia, petechiae on torso and with more acute bacterial causes

Altered LOC, seizures, and hypotension

40
Q

Meningeal signs

A

Nuchal rigidity

Indicates inflammation of the dura

41
Q

Brudzinski sign

A

Pt supine , tilt neck forward toward chest , if meningeal irritation = flex of the hips and knees

42
Q

Kernigs sign

A

Meningeal sign

Flex hip and knee on one side and then extending knee with hip still flexed . Hamstring spasm = pain in posterior thigh, back pain or difficulty with knee extension = + meningeal sign

Severe meningeal inflammation = opposite knee may flex

43

May report a URI, discomfort around jaw, ringing in ears

47
Q

BP PE and management

A

Sagging eyebrow, inability to close affected eye, disappearance of nasolabial fold and drooping at the affected corner of the mouth
