mL of NS and should infuse over 1 hour. Using tubing with a drop factor of 10 gtt/mL, how
many drops per minute should the linezolid be infused? __
(300x 10 )/ 60min = 50
A patient on a ventilator has an order for a continuous midazolam drip at 4 mg/h. The
midazolam concentration is 50 mg/50 mL of NS. Using an IV controller, how many
milliliters per hour should the midazolam be infused? __
50 mg/ 50 ml = 1 mg/ml
4 mg/ hr = 4 ml/4mg
,The patient has levofloxacin 500 mg ordered once daily. The levofloxacin is available in 100
mL of NS and should infuse over 60 minutes. Using an IV pump, how many milliliters per
hour should the levofloxacin be infused? __
100 ml of NS infused over 60 mins
100
The patient has vancomycin 750 mg ordered once daily. The vancomycin is available in 250
mL of NS and should infuse over 1 hour. Using tubing with a 10 gtt/mL drop factor, how
many drops per minute should the vancomycin be infused? __
(250 x 10 ) / 60 = 41.7 = 42

Linezolid 600 mg IV once a day is ordered for a patient. The linezolid is dissolved in 300
mL of NS and should infuse over 90 minutes. Using an IV controller, how many milliliters
per hour should the linezolid be infused? __
60mins/90mins = .6666667
300 x .6666667 = 200
An end-of-life patient has an order for fentanyl IV at 50 mcg/h. The fentanyl concentration
is 10 mcg/mL. Using an IV controller, how many milliliters per hour should the fentanyl be
infused? __
, 10 mcg / ml
50 mcg/ 10 mcg = 5
5 ml/ hr
Order: Begin a heparin drip per the facility’s protocol.
The patient’s weight is 154 lb.
Heparin Protocol
Bolus: Heparin 80 units/kg. Bolus vial contains 1,000 units per mL. Infusion: Heparin 18
units/kg/h using a concentration of heparin 25,000 units in 250 mL of NS (100 units/mL).
Calculate the number of mL/hr required to deliver continuous infusion.
154 lb / 2.2 kg= 70
18 x 70 kg = 1,260 units per hr
250 ml/25,000 = x ml/ 1,260
315,000 = 25,000x
x= 12.6
Order: Begin a heparin drip per the facility’s protocol. The patient’s weight is 96 kg.
