N307 Week 5 QUIZ 2024/2025 (COMPLIED
FROM EXAM) 100% CORRECT ANSWERS
Do infants have larger or smaller extracellular fluid volume versus older children
and adults?
Larger
Sensible fluid loss
loss that is perceived or is measurable. (wound drainage, GI tract, urine)
Insensible loss
Water lost thru the skin by sweating or being under heat lamp
Electrolyte Normal Levels in Children
K+: 3.7-5.0
Na: 134-143
Ca: 8.7-10.7
Mag: 1.6-2.4
Arterial PO2: 80-100
,Arterial PCO2: 32-48
Arterial bicarb: 18-25
Isotonic Dehydration
Proportionate loss of fluid and sodium
Extracellular loss
Hypotonic dehydration
•Greater loss of sodium than water
•Extracellular shift to intracellcular to compensate
•Examples: prolonged vomiting, diarrhea, renal disease, burns
Hypertonic dehydration
•Greater water loss than sodium
•Intracellular shift into extracellular to compensate
•Examples: diabetes insipidus, fluid volume overload
, mild dehydration
5% weight loss
Moderate pulse
Moderate dehydration
6-9% fluid loss
Severe dehydration
10% or greater fluid loss. fast and weak pulses
Oral rehydration therapy
•Recover patient with IV fluid resuscitation, oral rehydration therapy, change
environmental factors when applicable
•Oral rehydration best for mild or moderate loss
Fluid volume excess
•Too much fluid in vascular and interstitial compartment.
•Serum sodium normal
