Calculations

Front 1

milleq equation

Back 1

mEq=(mg X Valence)/MW

Front 2

Mosmol equaiton

Back 2

1) mOsm/L= (g/L)/MW X species X 1000
2) mOsm/amount=g/MW X species X 1000

Front 3

mEq/L of KCl = mEq/L K+ = mEq/L Cl-

Back 3

k

Front 4

General Rule about TPN

Back 4

if the gut works, use it

Front 5

Where is TPN given?

Back 5

central vein (reduces phlebitis

Front 6

When is the TPN timeframe appropriate

Back 6

patients needing long term (over 7d ays) of supplemental nutrition....NO justification for 4 days of TPN

Front 7

Some disease states that might require a tpn?

Back 7

severe gut dysfunction due to ex. crohns disease, ulcerative colitis, obstruction, short bowel syndrome from surgery, NPO

Front 8

4 items to check prior to TPN calculation?

Back 8

1) Water requirements (no overload or volume depletion)

Front 9

items to check prior to TPN

Back 9

water requirements....2) check albumin (low albumin will cause intravascular fluid loss, incorrect calcium, 3) check acidocity and alkalotic (bicarb, chloride.....4) calorites per gram of each

Front 10

Ph for acid for alkalosis

Back 10

acid is under 7.35....alk over 7.45....alk is high bicarb low Cl

Front 11

If pat is acidotic....need to have 50% sodium acetate instead of NaCl
