Hesi rn dosage calculation ( 56 Questions)
Question 1 of 56 :
Heparin 5,000 units 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 numeric value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 0.5
You can calculate the volume of heparin to administer using the following formula:
Volume (mL) = Dose (units) / Concentration (units/mL)
Here's what we know:
Dose: 5,000 units heparin (given)
Concentration: 10,000 units/mL (from the vial label)
Calculation:
Volume (mL) = 5,000 units / 10,000 units/mL
Volume (mL) = 0.5 mL
Therefore, the nurse should administer 0.5 mL of heparin.
