The healthcare provider prescribes interferon beta-1b 0.125 mg every other day for a client with multiple sclerosis. The nurse reconstitutes the single-use vial of powder labeled, "0.3 mg with 2 mL of sterile water." How many mL should the nurse administer to the client? (Enter the numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["0.8"]
The vial contains 0.3 mg of medication, which has been reconstituted with 2 mL of sterile water. Therefore, each milliliter of solution contains 0.15 mg of medication.
The prescribed dose is 0.125 mg, so the nurse should administer \( \frac{0.125\ mg}{0.15\ mg/mL} = 0.8333 \) mL of the solution.
After rounding to the nearest tenth, the nurse should administer 0.8 mL of the reconstituted solution to the client every other day.
