A nurse preparing to administer heparin 10,000 units subcutaneous every 8 hr. Available i heparin injection 20,000 units/mL. How many mL 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"]
Determine the desired dosage:
The nurse needs to administer 10,000 units of heparin.
Determine the volume per dose:
The heparin injection contains 20,000 units per 1 mL.
The nurse needs to administer 10,000 units per dose.
To find the volume per dose:
20,000 units / 1 mL = 10,000 units / x mL
Cross-multiplying gives us:
20,000x = 10,000
Dividing both sides by 20,000, we get:
x = 0.5 mL

Correct Answer is ["1.6"]
Explanation
Determine the desired dosage:
The nurse needs to administer 480 mcg of filgrastim.
Determine the volume per dose:
The filgrastim injection contains 300 mcg per 1 mL.
The nurse needs to administer 480 mcg per dose.
To find the volume per dose:
300 mcg / 1 mL = 480 mcg / x mL
Cross-multiplying gives us:
300x = 480
Dividing both sides by 300, we get:
x = 1.6 mL
Correct Answer is ["5.3"]
Explanation
Convert the child's weight from pounds to kilograms:
There are 2.205 pounds in 1 kilogram.
53 lb = 53 lb / 2.205 lb/kg = 24.04 kg (rounded to two decimal places).
Determine the total daily dosage:
The child is prescribed 10 mg/kg/day of clindamycin.
The child weighs 24.04 kg.
The total daily dosage is 10 mg/kg/day x 24.04 kg = 240.4 mg/day.
Calculate the dosage per dose:
The medication is to be administered in three divided doses.
The dosage per dose is 240.4 mg/day / 3 doses = 80.133 mg/dose.
Determine the volume per dose:
The clindamycin oral solution contains 75 mg per 5 mL.
The nurse needs to administer 80.133 mg per dose.
To find the volume per dose:
75 mg / 5 mL = 80.133 mg / x mL
Cross-multiplying gives us:
75x = 400.665
Dividing both sides by 75, we get:
x = 5.3422 mL
Round the answer to the nearest tenth:
Rounding 5.3422 to the nearest tenth gives us 5.3 mL.
