The Pyxis has 0.5 mg in 2 mL.The nurse plans to draw up ____mL to administer the correct dose of 0.125 mg. Do not include the unit of measurement in your answer. Include decimal in your answer. Write answer per hospital protocol and best evidence to ensure patient receives a safe dose.

Answer 1

To administer 0.125 mg of digoxin, the nurse should draw up 0.5 mL of the medication from the Pyxis.

Step-by-step explanation:

To administer the correct dose of 0.125 mg of digoxin (Lanoxin), the nurse should draw up 0.5 mL of the medication from the Pyxis. The Pyxis contains 0.5 mg of digoxin in 2 mL, so we can calculate the volume needed by setting up a proportion.

Using the formula:

(0.125 mg) / (0.5 mg) = x mL / (2 mL)

we can solve for x:

x = (0.125 mg * 2 mL) / 0.5 mg = 0.5 mL
