Q

ICP Pathophysiology

A

Increased pressure that compresses the brain
Compresses blood vessels that carry oxygen to the brain
Less blood means less oxygen resulting in a change of LOC (cerebral hypoxia)

Q

Epilepsy

A

Epilepsy, which is sometimes called a seizure disorder, is a disorder of the brain. A person is diagnosed with epilepsy when they have had two or more seizures.

51
Q

status epilepticus

A

A seizure that lasts longer than 5 minutes, or having more than 1 seizure within a 5 minutes period, without returning to a normal level of consciousness between episodes is called status epilepticus. This is a medical emergency that may lead to permanent brain damage or death.

52
Q

Seizures

A

What are seizures? Seizures occur when abnormal electrical signals are being rapidly fired for neurons in the brain. This can happen throughout the brain affecting both sides (generalized seizure) or being located in a specific area of the brain (partial or focal seizure).

53
Q

Types of Seizures

A

Tonic seizure: stiffening of the body, risk for falling

Clonic seizure: jerking, can be symmetrical or asymmetrical

Tonic-clonic: looses consciousness will experience a tonic phase then a cloning phase - usually no more than 3 minutes at risk for status epileptics with this type of seizure

54
Q

Seizure duration

A

if greater than 5 minutes or having multiple seizures in a row…activate emergency response team (will need immediate treatment to stop seizure (more on this in the nursing interventions)

55
Q

Absense Seizure

A

most common in paediatric patients
hallmark: staring into space
seems like child is daydreaming but can’t be snapped out of it

56
Q

Myolconic Seizure

A

Quick duration of jerking of the muscles, pt is aware and conscious
Very short… few seconds

57
Q

Nursing Interventions for seizures

A

Seizure precautions may include:
at bedside have suction and oxygen ready
IV access (to given anti-seizure medication, if needed)
padded side rails
pillow under head (to protect head)
bed in the lowest position
remove objects that can cause injury (remove any restrictive clothing or items the patient may be wearing….eye glasses etc. )

58
Q

What to do when your patient has a seizure?

A

Protect patient if they are standing up or sitting down
Turn them to they side
Do not restrain patient or try to hold them down
Protect head and extremities (pillow and bed pads help with this)
Doo not put anything in the patients mouth
Remove anything that can impede breathing

Note the time it started and Stopped

59
Q

Multiple Sclerosis

A

Auto immune disease where body attacks the myelin sheaths
Muscle spams and stiffness

60
Q

Myelin Sheaths

A

Protective layer of fatty tissue around the nerve cells in the central nervous system (brain and spinal cord) which help the body move by sending electric impulses from the brain to the rest of the body

61
Q

Diagnosis MS

A

MRI and CT scan
3-1mm sclerotic brain plaques on MRI
Lumbar spinal punture
Elevated gamma globulin in cerebrospinal fluid (CSF)

62
Q

69
Q

Parkinson’s Disease

A

Progressive disorder
Unlike MS and MG (body attacking itself)
Your body progressively stops making dopamine
When your body stops making dopamine the messages from the brain to the body do not get relayed = breakdown in central nervous system = breakdown in motor function of all out other muscles

Low dopamine
High acetylcholine

70
Q

Signs and Symptoms Parkinson’s

A

Progressively slow movements
Freezing and rigidity walking
Shuffling gait - decreased arm swinging
Pill rolling
Tremors at rest
No expression face

A

Levodopa and Carbidopa
Avoid Protein (levodopa)

73
Q

Myasathesin Gravis

A

It’s an autoimmune condition where the body attacks the receptors that allow for voluntary muscle control, which leads to muscle weakness.

74
Q

What voluntary muscles are involved In MG?

A

Eyes: most likely will be the first sign something is wrong
Throat: another common sign…hoarse voice and problems swallowing
Face
Arms/Legs
Respiratory muscles for breathing (in severe cases)

75
Q

Signs and Symptoms of Myasthenia Gravis

A

HALLMARK: muscle weakness becomes worse with activity (especially repetitive activity) but will improve after resting the muscle.
Weakness neck, face, arms/legs/hands
Eyelid drooping
mask-like: no expression…looks very sleepy
choking or gagging when eating (difficulty swallowing)
No energy…very fatigued…gets worse throughout the day as muscles are used
double vision
Slurred speech
Short of breath (can extend to respiratory muscles)

76
Q

Complications of Myasthenia Gravis

A

Myasthenia gravis can go into remission where the patient doesn’t have signs and symptoms, but some patients can experience severe acute exacerbation with a complication called Myasthenic Crisis.

This is where the disease is becoming worse and the patient may need intubation and mechanical ventilation to breathe.

Risk factors for experiencing Myasthenic Crisis: improper dosage (not enough) of anticholinesterase meds to treat this condition, stress (physical…surgery or mental), and respiratory infection.

77
Q

cholinergic crisis

A

A cholinergic crisis develops as a result of overstimulation of nicotinic and muscarinic receptors at the neuromuscular junctions. This is usually secondary to the inactivation or inhibition of acetylcholinesterase (AChE), the enzyme responsible for the degradation of acetylcholine (ACh)

78
Q

Signs and Symptoms of Cholinergic Crisis:

A

Think of the signs and symptoms experienced during cholinergic crisis similar to the parasympathetic nervous system being in overdrive:

Pupil constriction
Bronchoconstriction….eventually respiratory failure
Increased salivation and mucous production
GI problems: abdominal cramping, vomiting, diarrhea
Bladder incontinence
Bradycardia

79

81
Q

Alzheimer’s

A

It’s a chronic brain disease that is a type of dementia.

It occurs because neurons in the brain lose the ability to communicate and eventually die.

This is mainly due to the development of plaques and tangles. These plaques and tangles lead to a progressive loss of the ability to:
problem solve, communicate, recall memories, perform everyday tasks, and care for one self

patients will be completely dependent on someone for care. It is not reversible and no cure is currently available. Medications are available to help manage symptoms.

82
