Calculations III Flashcards
IV and Enteral Nutrition
Fluid Requirements
Estimate
20-30mL/kg/day
TEE equation
TEE = BEE x activity factor x stress factor
activity factor = 1.2 if in bed, 1.3 if out of bed
stress factor = 1.2 minor surg, infxn = 1.4, trauma = 1.5, burns >30% body = 1.5-2
Carbs
how many kcal/g?
max infusion rate?
3.4 kcal/g
max inf rate 4mg/kg/min
Non-protein calories are typically __% carbs and __% fats?
70-85% carbs
15-30% fats
Fats/lipids
how many kcal/g? What about the specific lipid formulations?
Needs a _____ micron filter
9kcal/g
10% ILE = 1.1 kcal/mL
20% ILE = 2 kcal/mL
30% ILE = 3 kcal/mL
Needs a 1.2 micron filter
Proteins
how many kcal/g?
What are the protein requirements for a patient at home vs in hospital?
How to calculate Nitrogen intake?
4 kcal/g
at home: 0.8-1 g/kg/day
hospital: 1.2-2 g/kg/day
Nitrogen = g protein / 6.25
equation for corrected calcium
Ca corr = Ca measured + [(4-Alb) x 0.8]
calcium and _______ will precipitate when combined
phosphorous
what order should you use to mix a TPN bag when calcium and phosphorous are involved
dextrose and aa –> add phos –> add other non-Ca – > shake and agitate –> add Ca at latest possible moment
the mEq/L of calcium + the mEq/L of phosphorous must not exceed ___mEq/L
45 mEq/L
How is warfarin administered to a patient on a tube feed?
hold tube feeds one hour before and one hour after administering warfarin
tetracyclines, fluoroquinolones and levothyroxine must be given
A. with a tube feed
B. directly after a tube feed
C. right before a tube feed
D. separate from tube feed
D. separate from tube feed
will chelate with polyvalent ions
ciprofloxacin oral suspension is not compatible with tube feeds. T or F?
true, IR tablets are preferred (crush and mix with water)
phenytoin is compatible/not compatible with tube feeds? Special instructions?
not compatible, separate by 2 hours
