Heparin 5,000 Units intravenous (IV) is prescribed as a loading dose, to be administered over 5 minutes for a client with thrombophlebitis. The vial is labeled, "10,000 units/mL." How many mL should the nurse administer?
(Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["0.5"]
To calculate the volume of heparin solution, we need to use the formula:
Volume (mL) = Dose (units) / Concentration (units/mL)
Plugging in the given values, we get:
Volume (mL) = 5,000 units / 10,000 units/mL
Simplifying, we get:
Volume (mL) = 0.5 mL
Rounding to the nearest tenth, we get:
Volume (mL) = 0.5 mL

Correct Answer is ["30"]
Explanation
To calculate the infusion rate, we need to use the formula:
Infusion rate (mL/h) = Dose (mg/min) x Volume (mL) / Concentration (mg)
Plugging in the given values, we get:
Infusion rate (mL/h) = 2 mg/min x 60 min / 4 mg/mL
Simplifying, we get:
Infusion rate (mL/h) = 30 mL/h
Correct Answer is ["83"]
Explanation
To calculate the infusion rate, we need to use the formula:
Infusion rate (gtt/min) = Volume (mL) x Drop factor (gtt/mL) / Time (min)
First, we need to convert the volume from liters to milliliters by multiplying by 1,000. In this case, 1 liter is equivalent to 1,000 mL.
To convert the time from hours to minutes, we need to multiply by 60. In this case, 12 hours is equivalent to 720 minutes.
Plugging in the given values, we get:
Infusion rate (gtt/min) = 1,000 mL x 60 gtt/mL / 720 min
Simplifying, we get:
Infusion rate (gtt/min) = 83.33 gtt/min
Rounding to the nearest whole number, we get:
Infusion rate (gtt/min) = 83 gtt/min
