- Irritable - Lethargic - Vomiting - Change in appetite
29
what are the major signs of viral meningitis in older children?
- Preceded by a nonspecific febrile illness - Headache - Muscle ache - malaise - N/V - Photophobia - nuchal/spinal rigidity
30
What are theree causes of Bacterial meningitis
- H-influenza - Strep - neisseria
31
How is H-influenza prevented?
Hib vaccine
32
What are some Bacterial meningitis specific signs in an infant?
- High-pitched cry - Temp regulation failure - Floppy baby
33
What are some signs/symptoms of Bacterial meningitis in infants
- poor/sick feeding - Vomiting - High pitched cry - bulging fontanel - Fever or hypothermia - poor muscle tone
34
what are some signs/symptoms of Bacterial meningitis in older children
- Abrupt onset - Fever/chills - HA - Nuchal rigidity (neck) - Irritable - agitation - rash - seizure - drowsy + kerning or brudzinski's sign - Opisthotonus posture
35
What are the main nursing interventions involved with caring for a child with Bacterial/viral meningitis
- Minimize ICP by elevating HOB and monitoring fluids in, maybe an icepack on head - Monitor of cereal edema - Use antipyretics *do not use opioids* - Monitor for complications
36
What is epilepsy?
Chronic seizure disorder
37
What are the two types of seizures?
Generalized and focal
38
What is a generalized seizure?
One that occurs in both hemispheres of the brain
39
What is a focal seizure?
one that occurs in on hemisphere of the brain
40
What are some causes of seizure disorder in infants?
- perinatal hypoxia - hypoglycemia - cong. diseases - infections - metabolic or degenerative diseases - drug withdraw
41
What are some causes of seizures in older children?
- Febrile infections - Head injury - Lead toxicity - Drugs - Genetic disorder - neoplasms(tumor)
42
What does the term tonic-clonic mean
Also known as a grand mal seizure.
43
What are the characteristics of a tonic-clonic seizure?
Loss of consciousness occurs first and lasts about 10 to 20 seconds, followed by muscle convulsions that usually last for less than two minutes.
44
What are some characteristics of focal seizures?
Can be motor or non-motor - each person is different - can cause odd behaviors or uncontrolled movements - can cause blank stares - can cause emotions - Sensory distortions - Basically, they can be anything
45
What are some major assessment data to collect from a patient with a seizure disorder?
- Order of events and duration - Participatory events - What body parts are involved
46
You also need to ask what normally happens ____ the seizure? Why?
After because some patients will have decreased LOC, motor, speech, and orientation after. this puts them at a high risk for injury
47
A patient is have a seziure. What do you do?
- Help them to the ground of standing - Place them in the rescue position - Protect their airway - Protect their head/neck - Wait of the seizure to end
48
What is one very important consideration about drug administration for seziure medications?
TheyApr have a very short window of administration and need to be given as close to the time prescribed as possible
49
Aprox ____ of migraine sufferers have their first attack before ____
20% 5th birthday
50
How does a migraine appear in children 5 and under?
- They look ill - have abdominal pain - vomit - strong need to sleep - irritable - they cry or rock - seak somewhere dark and quiet
51

52
What are some teaching points for migraines?
Keep a diary of triggers | the child may outgrow them. it happens
53
What is the main reason we measure child head circumference?
to detect hydrocephaly
54
What causes hydrocephaly?
50% is idiopathic | the rest is associated with meningitis, trauma, intraventricular hemorrhage, or myelomeningocele
55
What is the patho of hydrocephaly?
It is an imbalance of the production and absorption of CSF. this overproduction causes increased buildup in the brain in leads to increased ICP
56
WHat are the two types of hydrocephaly
Communicating and non-communicating
57
What is communicating hydrocephaly
Normal production of CSF with under absorption
58
what is non-communicating hydrocephaly?
CSF traped in ventricles
59
What are the s/s of hydrocephaly in infants?
Splitting sutures, bulging fontanels, irritability, and increased head circumference
60
what are the s/s of hydrocephaly in older children?
- Setting sun eyes - seizures - irritability - increased head circumference
61
What is the treatment for hydrocephaly?
Ventro peritoneal shunt
62
Why do we NEVER give children under 18 aspirin?
BEcause it can cause Reye syndrome
63
What is Reye syndrome?
A rare syndrome caused by the interaction of a virus and aspirin. The interactions causes Metabolic encephalopathy and fatty liver
64
What are the key nursing management for Reye syndrome?
- PReventions - Strict I's and O's - Control cerebral edema - When the child wakes up they may have mental defects from brain damage
65
What is Guillian Barre?
An inflammatory syndrome associated with immunizations and viruses
66
What is the patho of guillian barre?
Acute inflammatory demyelinating neuropathy occurs. | Causing reduced motor function and reflexes in a distal to proximal pattern until total paralysis occurs.
67
How is Guillian Barre treated?
IV immune globulin (very expensive)
68
What are the nursing managements for Guillian Barre?
- IV meds - Prevent complications from immobility - monitor respiratory status - Nutritional support - Emotional support
