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 ["3.5"]
Explanation
First, we need to convert the child's weight from pounds to kilograms.
Since there are approximately 2.20462 pounds in 1 kilogram, 52 pounds is equivalent to 52/2.20462 =
23.587 kilograms.
The prescribed dose of digoxin is 7.5 mcg/kg/day, so for a child who weighs 23.587 kg, the total daily dose is 7.5 * 23.587 = 176.9 mcg/day.
Since the medication is available as a 50 mcg/mL elixir, the nurse should administer 176.9/50 = 3.538 mL/day.
Since the medication is to be administered once daily, the nurse should administer 3.538 mL per dose. Answer: 3.5
