croup is caused by _ virus
and is mc in _ year olds
parainfluenza
3-6 mo
tx for croup

cystic fibrosis
PE findings of CF
scattered ronchi bilat
dullness to percussion
mild hepatomegaly
mild LE edema
3 CXR findings of CF
focal atelectasis
mucus plugging
hyperinflation
dx for CF
sweat chloride test
CF is an autosomal recessive mutation in the _ gene
CFTR
CF is associated w. recurrant respiratory infxns caused by
pseudomonas
management of CF
chest physiotherapy
high fat diet
fat soluble vitamin supplements
exacerbations: abx
mcc of foreign body aspiration
food
5 rf for foreign body aspiration
institutionalization
advanced age
poor dentition
etoh
sedatives
mc location for aspiration
mainstem
right lobar bronchus
3 PE findings of foreign body aspiration
foul smelling nasal d.c
inspiratory stridor
wheezing
+/- decreased breath sounds
CXR finding of foreign body aspiration
expiratory film: hyperinflation of affected side
_ is necessary for appropriately evaluating/monitoring ventilation
ABG
what type of bronchoscopy is preferred in peds
rigid
what should you consider administering prior to removal of a nasal foreign body object
oxymetazoline drops -> shrinks mucous membrane

management of intraocular foreign bodies (3)
topical anesthetic
topical vs systemic abx
immediate ophtho referral
what pathogen are you worried about w. eye injuries associated w. soil/vegetation
bacillus cereus
dz that affects premature infants that are born before the lungs produce adequate amounts of surfactant
hyaline membrane dz

rf for hyaline membrane dz
infants < 30 weeks gestation at birth
what 3 antenatal tx can help with hyaline membrane dz
-antenatal betamethasone IM x 2 w.in 24-48 hr of birth
-artificial surfactant thru endotracheal tube
-PEEP
mcc cause PNA in peds vs adults
peds: RSV
adults: flu

what makes you think viral PNA vs bacterial
rapid onset
milder sx
4 sx of bacterial PNA
fever
dyspnea
tachycardia/pnea
+/- sputum
CXR findings of bacterial PNA

inpt: ceftriaxone + azithro/FQ
RSV is the mcc of _ in peds (2)
bronchiolitis
PNA
