A
percus, ausclate - order is important: visualize first - should be round and soft, not firm, shouldn’t see veins, will sound resonant, ausculate, percus, then belly tickles, then palpate, then go down, urine and bowel samples, x-ray, CT, least invasive to most, then labs.

sign of something else - dietary, innervation, psychological, etc....
29
intestinal irriations
UC and crohns
30
UC
usually just colon and rectum. usually diagnosed in teenage years.
31
crohns
any part of digestive tract. usually an immune response where cells attack lining of gut. both UC and crohns need bowel rest.
32
UC and crohns treatment
managing stress and diet. might need an ostomy for bowel rest.
33
intacaception (sp)
part of intestines goes into another section - very painful.
34
intusseception - treatment
saline enemas can help, surgery last option,
35
appendicitis - what causes it?
most common surgery for young children, side to clutch is called mcburn site. fecolith = is what causes appendicitis - piece of poop that covers the opening into the appendicitis.
36
appendicitis - assessment - check for 1 thing
rebound tenderness, do scans to see if it's ruptured, if it hasn't popped - give IV antibiotics, if that's ok, switch to oral antibiotics.
37
appendicitis - 90% of time
end up doing appendectomy. usually go home by day 3.
38
how to calculate daily fluid maintenence requirements
100 ml/kg for 1st 10 kg body weight
50 ml/kg for 2nd 10 kg body weight
20 ml/kg for remaining body weight
To find volume per hour
Divide total amt by 24 hrs to obtain rate in ml/hr
39
skin temp - what percentages?
Cool hands or feet = 5% loss
Cool to elbows and knees = 10% loss
Cool to shoulders and hips = 15% loss
40
no tears until
2 months
41
The distribution of water between the ECF and ICF depends on active transport of:
potassium into cells (intra cellular)
sodium out of cells (extra cellular)
42
Isotonic (Isonatremic) Dehydration
Primary type of dehydration for all children
Sodium and water loss in equal balance
Vascular loss = shock
43
Hypotonic (Hyponatremic) Dehydration
Low serum Na+
Too much free water replacement
Osmotic shift from ECF to ICF
Vascular shock
44
Hypertonic (Hypernatremic) Dehydration
Increased intake of sodium
Concentrated formulas, rehydration fluid, intravenous fluid
Osmotic shift to ECF
45
dehydration - CAUTION:
CAUTION: Do not add Potassium (K+) until serum electrolytes are checked and child has urine output noted
NO Pee…. NO K+
46
