  1. ____ mL = 1 tsp
    5 mL
  2. ____  mL = 1 tbs
    15 mL
  3. ____  mL = 1 oz
    30 mL
  4. ____  mL = 1 pint 
    500 mL
  5. ____ mL = 1 quart or 1 liter
    1000 mL
  6. 1 mg = gr ____ 

    gr i =  ____ mg

    gr ____ = 1 g
    1/60 gr

    60 mg

    gr XV

  7. ____mg = 1 g

    ____ mcg = 1 mg
    1000 mg; mcg
  8. 1 T =   ____ t
    3 t
  9. Abbott =  ____ gtt/mL
    15  gtt/mL
  10. Cutter = ____  gtt/mL    
    20 gtt/mL    
  11. Calculate Running Time:
    Problem: 1000mL DLR; Infusing at 25 gtt/min; Administration set is 20 gtt/mL. Calculate the Running Time.
    • = 25 gtt/min
    • SO ....
    • 20,000 gtt = 25 gtt/min ⇒ 20,000 ÷ 25
    • = 800 min
    •   Convert⇒ (800÷60=13.3)-(0.33x0.60=0.199)
    • = 13 hours and 20 minutes
  12. The concentration per volume administered over an ordered period of time is the most ____________ and ___________ method of drug administration. The administration of potent drugs may be ordered by concentration per minute or hour.
    Accurate & Safest
  13. Problem: Infuse Lidocaine 2g in 500mL DW at 2mg/min. What is the rate of flow with a 60gtt/ml set?
    • 2000mg : 500mL = 2mg : x mL  
    • 2000 x = 1000
    • x = 0.5 gtt/min (to be given over 1 min)

    • = 30 gtt/min 
  14. Example: The healthcare provider has prescribed a continuous IV of heparin 25,000 units in 250 mL of NS via infusion pump to infuse at a rate of 18 units/kg/hr. The client weighs 110 pounds. What hourly rate should be set on the infusion pump?
    • The nurse must first convert the client’s weight from pounds to kilograms.
    • 2.2 lbs = 1 kg
    • 2.2 lbs: 1 kg = 110 lbs: x kg
    • 2.2x = 110
    • x = 50kg 

    • To calculate the hourly rate for the heparin infusion, multiply the client’s weight in kg by 18 units of heparin:
    • 50 x 18 = 900 units of heparin per hour 

    • Set up the problem to determine the mL per hour that will provide 900 units of heparin per hour. 
    • 25,000 units : 250mL = 900 units : x mL
    • 25,000x = 225,000
    • x = 9 mL per hour
