Question

A nurse is preparing to administer digoxin 0.25 mg IV bolus. Available is digoxin injection 0.25 mg/ml. How many ml should the nurse administer per dose?

Answer 1

The nurse should administer 1 ml of digoxin injection since the prescribed dose is 0.25 mg and the available concentration is 0.25 mg/ml.

Step-by-step explanation:

The student has asked how many milliliters (ml) should a nurse administer of digoxin injection when the prescribed dose is 0.25 mg, and the available digoxin injection has a concentration of 0.25 mg/ml. To determine the volume to administer, use the following calculation:

Dose (mg) ÷ concentration (mg/ml) = volume to administer (ml)

So, for a 0.25 mg dose with a concentration of 0.25 mg/ml, the calculation is 0.25 mg ÷ 0.25 mg/ml = 1 ml.

Therefore, the nurse should administer 1 ml of the digoxin injection to provide the 0.25 mg dose.
