A nurse is preparing to administer heparin 10,000 units subcutaneously every 8 hours. The available heparin injection is 20,000 units/mL. How many milliliters should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["0.5"]

To calculate the required mL of heparin injection per dose, we need to use the following formula: mL = (units per dose) ÷ (units per mL)

Substituting the given values in the formula, we get:

mL = (10,000 units) ÷ (20,000 units/mL) mL = 0.5 mL

Correct Answer is ["2"]

Explanation

To calculate the volume to be administered, the nurse should divide the prescribed dose (200 mg) by the

concentration of the available medication (300 mg/3 mL): 200 mg / (300 mg/3 mL) = 2 mL.

Correct Answer is ["1.6"]

Explanation

To calculate the number of mL the nurse should administer per dose, you need to divide the dose of filgrastim in mcg by the concentration of the filgrastim injection in mcg/mL.

480 mcg ÷ 300 mcg/mL = 1.6 mL

So, the nurse should administer 1.6 mL of filgrastim injection per dose.
