Q

structural differences

A

larger heads, mobile spines, fontanelles fuse after brain growth slows, skull thickness increases with age, skull pliability decreases with age, vascular brain. develops rapidly in toddler years

Q

pediatric stroke

A

perinatal stroke is last few months of pregnancy to 1mo, childhood stroke is 1mo-18yr. similar mx to adult, nutrition and hydration.

23
Q

perinatal stroke

A

cause unknown. r/f congenital heart disease, placenta disorder, blood clot disorder, infections. sx are repetitive motions, twitching, apnea with staring, decreased mvmt, weakness on one side, hand preference before 1yr.

24
Q

childhood stroke

A

r/f are congenital heart disease, disease affecting brains arteries, infections, head trauma, sickle cell, autoimmune. sx are FAST, sudden ha, vomiting sleepy, weakness, numbness on one side, difficulty speaking, vision loss, dizzy. dont delay with tx

25
neural fibral metosis
genetic, chromosomal, causes benign tumors to grow under skin and within eyes. associated with bone conditions, increased bp, learning difficulties, seizures. sx are lisch nodules in eyes, lumps on skin, cafe au lait spots, and skin fold freckles.
26
neural fibral metosis mx
skin assessment, seizure mgmt, no tx,
27
meningitis
infection of meninges, occurs any age,
28
meningitis sx
fever, ha, irritable, nuchal rigity, photophobia, poor feeding, bulging fontanels, high pitch cry, rash, seizures, opisthotomos
29
dx of meningitis
lumbar punct (cloudy, decreased glucose, positive gram stain is bacterial. clear, normal glucose and negative gram is viral), kernigs lay flat and bend hip and positive will have pain in body, brudzinskis lay flat and bend neck in and knees will bend up if positive
30
meningitis tx
bacterial needs isolation, droplet precaution, abx. viral is self limiting and less severe. manage icp and monitor neuro status
31
encephalitis
inflammation of brain tissue. from virus, toxins, bacteria, parasites, usually vector borne viruses. dx with lumbar punct and MRI
32
sx of encephalitis
fever, ha, photophobia, altered loc, lethargy, drowsy, weak, seizures
33
tx of encephalitis
seizure precaution, antiviral therapy, prevent with vaccines, mosquito and tick bite prevention.
34
reyes syndrome
viral illness plus aspirin leads to mitochondrial damage then toxins released lead to increased ammonia and acute noninfla encephalitis and fatty degenerative liver failure.
35
reyes sx
neuro changes, vomiting, drowsy, steatosis of liver, hypoglycemia, hepatomegaly, infection, coma, encephalopathy.
36
tx of reyes
poor prognosis more severe the sx are, decrease ammonia levels like low protein and electrolytes/corticosteroids/diuretics.
37
seizure disorders
electrical disturbance in brain. classified by location, severity, sx, frequency, duration, etiology. causes motor, sensory and cognitive changes.
38
focal seizure
originates in one part or hemisphere of brain. aware vs impaired awareness. motor is clonic, tonic, atonic, myoclonic, lip smacking, stiff on one side. non motor is auditory/visual disturbance, tingling, anxiety, anger.
39
generalized seizure
involves both hemispheres, usually impaired awareness. motor is tonic clonic, atonic, myoclonic. non motor is absence (behavior arrest), localized twitching
40
epilepsy
recurrent unprovoked seizures, resolved if no seizure for >10yrs or off antiepileptics for >5yrs. dx with two unprovoked seizures more than 24hr apart, one unprovoked seizure with high probability of repetition, epileptic syndrome present.
41
epilepsy tx
use vagal nerve stimulator, medications, safety interventions for during seizure.
42
status epilepticus
emergency, seizure >5min or series without recovery in between. convulsive or nonconvulsive based on mvmt.
43
timing during status epilepticus seizure
onset to 5 min- ABC's with cardio rr monitor, safety, IV access, blood glucose, benzodiazepine 5min- give one benzo (lorazepam, midazolam, diazepam) 10-15min- first dose of antiseizure rx (fosphenytoin, valproate, levetiracetam), eeg >15min- mechanical ventilation, transport to picu
44
febrile seizure
acute seizure triggered by high fever in kids <7yrs, body temp >101.2, may develop epilepsy. eeg for dx. self limiting
45
tx for seizure disorders
monotherapy preferred antiepileptic rx, consistency with rx, caregiver education on safety, medical alert bracelet, update school
46
conjunctivits
pink eye, infla of conjunctiva, bacterial, viral, allergic.
47
conjunctivits sx
redness of conjunctiva, itching, crusting of eyelids, purulent drainage bacterial, watery drainage viral
48
conjunctivitis tx
highly contagious, cold or warm compress, clean eye from inner canthus out, abx, return to school when sx stop
49
visual impairment
causes are genetic, infection, disorders. do vision screening, snellen, picture, tumbling E, peripheral vision, opthalmoscopic exam, misalignment testing with cover test or corneal light reflex, color vision screen with ishihara test.
50
common visual impairment
myopia- nearsighted, see close objects hyperopia- farsight, see far astigmatism- curved cornea or lens, all distance blurry and star lights strabismus- cross eye
51
otitis media
causes are anatomy, short eustachian tube with horizontal positioning, cant blow nose, drinking while laying flat, bacterial or viral spread from rr infection.
52
sx otitis media
fever, ear pain, pulling at ear, fussy, crying when laying down, poor feeding, fluid drainage, opaque tympanic membrane, lympadenopathy.
53
otitis media tx
analgesics, heat or cold packs, abx, ear plugs when swimming, pressure equalizing tubes
54
hearing deficits
genetic, aquired, or unknown cause. suspected if absent startle reflex or no turn to noise at 6mo. will have speech delays or appear inattentive. needs hearing screenings.
