The physician has ordered Recombivax 10 mcg IM for hepatitis B vaccination. The medication is supplied in 5 mcg/0.5 mL. How many milliliters will the nurse administer?
The Correct Answer is ["1.0"]
Ordered 10 mcg.
Supplied concentration = 5 mcg / 0.5 mL → that equals 10 mcg per 1.0 mL.
Volume needed = 10 mcg ÷ (10 mcg/mL) = 1.0 mL.
Correct answer: 1.0 ml
