  1. IV Fluids
    D
    W
    NS
    D5W
    • D = destrose
    • W = Water
    • NS = normal saline (isotonic) in water 0.9%
    • D5W = 5% dextrose inwater
  2. Microdrip drip rate
    Macrodrip rates
    Infusion Pumps
    Microdrip = 60gtt/ mL

    Macrodrip - drops/ mL differ by manufacturer usually 10-20gtt/mL

    • Infusion pumps - electric pump - you input total mL to be infused and mL/ hour
    • tubing factor is alway 60 gtt/ mL
  3. Labeling IVs
    • Patient Name
    • room
    • bed
    • date time
    • order
    • initials
  4. Basic IV drip rates
    (# of mL to infuse x TF) / # of minutes = gtt/ min

    TF = tubing factor
  5. IV calculations with an Infusion Pump
    # of mL ordered / # of hours to run = mL/ hr
  6. Calc for how long an IV will run
    # mL / # mL/hr = # hours to run
  7. Use Microdrip tubing when:

    Use Macrodrip tubing when:
    • Microdrip:
    • IV is to be adminsitered over long period
    • small amount of fluid is to be infused
    • macrodrops/ min are too few - may clot

    • Macrodrip:
    • large amount of fluid over short time
    • microdrops/ min are too many - counting drip rate becomes difficult
  8. Signs of IV infiltration
    infiltration = iv pushed out of vessel - fluid is enerting tissue

    • swelling
    • pain
    • coolness
    • pallor at the insertion site (pale)
  9. admixture
    premixed IVPB
  10. IVPB general rule for infusion time
    if drug into does not specify use:

    30 min/ 50 mL solution (FOR ADULTS)
  11. PICC
    peripherally inserted central catheter

    longterm indwelling catheter
  12. Enteral Nutrition
    intermittent
    cyclic
    continuous
    Enteral feeding through NGT, PEG tube, G tube, J tube

    • intermittent - delivered at regular intervals
    • cyclic - giving formula over several hours fo the day
    • continuous - infused constantly
