1.The patient is receiving IV heparin infusion at 13mL per hour. The heparin is supplied as a
25,000 units in 500 mL of NS. How many units her hour is this patient receiving? Round to the
nearest whole number. 650 units
2a.The patient is receiving an IV heparin infusion. The medication is supplied as 25,000 units in
500mL of NS. The patient is receiving 1200 units per hour. How many mL is the medication
running at? Round to the nearest whole number. 24mL
2b.The patient from the above question needs a bump up in their heparin as the aPTT is not
therapeutic. Per the protocol the RN is supposed to increase the heparin gtt by 250 units. Based
on the increase what will the new rate for the heparin gtt be in mL per hour? 29mL
3. You as the RN as initiating a new heparin gtt on a patient that was admitted with an NSTEMI.
The protocol states that you need to give a heparin bolus of 7500 units and then start the gtt at
850 units per hour. The vial for the bolus is given to you from pharmacy as a 1mL for 1000 units
of heparin. The gtt is given to you as 25,000 units per 500mL. How many mL will you administer
for the bolus and how many mL per hour will the gtt be started at? Round the bolus to the
nearest 10th and round the gtt rate to the nearest whole number. (This is a two answer
question). 7.5mL and 17mL
4a. A patient is on a heparin gtt and is being infused at 30mL per hour. If the medication is
delivered in a bag of 25000 units per 500mL of D5W, how many units is the patient receiving
per hour? 1500units/hr
4b. The above patient needs to have their dosing of heparin changed based on a low aPTT
result. Per the policy it states to change the dosing by 400 units per hour. What will the new
rate be in mL per hour? 38mL/hr
5a. Your patient is started on a heparin gtt running at 45mL per hour. The bag that is supplied
to you is given supplied at 25,000 units in 500mL of normal saline. How many units per hour is
your patient receiving?
5b. You as the nurse receive a phone call from lab on the patient above. Per the lab tech the
aPTT for your patient is greater than 240. Per the hospital protocol, which you are following, it
states that you need to pause the heparin gtt for 1 hour and when you restart it to decrease by
a large dose, which is 250units per hour. Once you restart the heparin gtt how many mL of
heparin will the patient be infusing at? Round to the nearest whole number.
5c. You then receive another phone call after 6 hours stating that the patient is still
supratherpeutic on their aPTT and your patient has signs of bleeding. You talk to the physician
that states that you should just run the heparin gtt at 850units/hr as they need it for their
elevated troponins, but we would like to not have them so therapeutic on the labs. What will
you as the nurse run the pump at in mL per hour? Round to the nearest whole number.
6a. A patient is on a heparin gtt and per the protocol the gtt needs to be decreased by 125
units. The patient is currently running 18mL of heparin. The bag that is supplied by pharmacy is
25,000 units per 500mL. How many units is the patient currently running?
6b. Based on the information supplied in the previous question, how many mL of heparin will
the patient be running after the dose is adjusted? Round to the nearest whole number.
6c. The patient is running the heparin infusion for 24 hours with no adjustment. The aPTT
comes back incorrect and a dosing change has to be made. Per the protocol the nurse should
adjust this medication, by increasing by 400 units. How many mL/hr will the patient be running
after the dosing change?
