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.)
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 ["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.
Correct Answer is ["0.9"]
Explanation
To find out how many mL of gentamicin the nurse should administer, we need to set up a proportion. If 40 mg of gentamicin is equivalent to 1 mL, then 36 mg of gentamicin is equivalent to x mL.
The proportion can be writen as 40/1 = 36/x. Solving for x, we get x = (36 * 1) / 40 = 0.9 mL.
The answer is rounded to the nearest tenth as instructed.
