Please help

You need to convert mg to mcg or vice versa. Then you need to use your formula to figure out the rest.

The physician orders digoxin 0.1 mg orally every morning for a 6-month-old infant with heart failure. Digoxin is available in a 400 mcg/ml concentration. How many milliliters of digoxin should the nurse give? Answer:

Start by converting micrograms (mcg) to milligrams to find out how many milligrams of digoxin are in each milliliter. Then you will be able to figure out how many milliliters are needed. Hope that helps.

I would convert the order (mg) to what's on hand (mcg). Once your units of measurement agree, use this formula Dose ordered, divided by concentration on hand, multiplied by the volume. That is, 100 mcg divided by 400 mcg, multiplied by 1 ml. Of course your mcg will cancel out, leaving you with ml as your unit of measurement, and your final answer as 0.25 ml.

Moved to Nursing Student Assistance Forum, since better suited to this type of inquiry.

We do not do your homework for you, though we alway say that if you show us how you tried to figure it out we can help you see where you went wrong.

LeeLee has very helpfully given you the answer, though; you should know that this is a question seeking to find out whether you know your conversions -- like mg to mcg-- and is only partly basic division. You will see a lot more of these in school, and at work, so you'd better learn how to do them.
