IVFs Flashcards
Replacement fluids should be __-tonic
Isotonic
LR, NS
Maintenance fluids should be __-tonic
to make up for insensible losses
Hypotonic
D5W, 1/2 NS
D5W is composed of ____ with 25mg Potassium
1/2 normal saline
Colloids have solids suspended in fluid and include:
plasma, RBCs, Plts
stay in vasculature thus providing oncotic pressure
Crystalloids fluids include:
LR, NS, D5W, hypertonic saline
Hypertonic fluids include:
D10W, D20W, D50W
3% NaCl, 5% NaCl
Maintenance Fluid Rate is calculated based on ___.
weight
What is the 4-2-1 rule for fluids?
40 ml/kg/hr for the first 10kg of body mass
20 ml/kg/hr for the second 10kg of body mass
1 ml/kg/hr for any kilogram of body mass > 20kg
What is the amount of maintenance fluids required for a 45 kg individual?
70kg
10kg + 10kg + 25kg = 45 kg
40ml + 20ml + 25ml = 85 ml/hr
10kg + 10kg + 50kg = 70kg
40ml + 20ml + 50ml = 110 ml/hr
Fluid bolus is calculated by
__ mL per kilogram of weight
ex) Fluid bolus for 45 kg
20ml/kg
20ml x 45kg = 900ml
