The healthcare provider prescribes heparin 3 units/kg IV push for a client who weighs 175 pounds. The vial is labeled, "100 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 ["2.4"]
Convert the client's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds.
Calculate the total number of units of heparin needed by multiplying the client's weight in kilograms by the prescribed dosage (3 units/kg).
Determine the volume of heparin to administer by dividing the total number of units needed by the concentration of the vial (100 units/mL).
The calculation:
Client's weight in kg: 175 pounds / 2.2 = 79.55 kg (rounded to the nearest tenth)
Total units of heparin needed: 79.55 kg 3 units/kg = 238.65 units
Volume of heparin to administer: 238.65 units / 100 units/mL = 2.39 mL
Therefore, the nurse should administer 2.4 mL of heparin. (rounded to the nearest tenth)
