A physician orders Lanoxin elixir 125 mcg daily for a child. The medication available is digoxin elixir 0.05mg/ml. How many milliliters are needed for a one-month supply?

Options:

A. 60ml

B. 75ml

C. 30ml

D. 45ml

Explanation:

For one-month supply, 75 ml is needed.

Calculation:

First, convert mcg (microgram) to milligram (mg):

1 mcg = 0.001 mg

125 mcg = 125 × 0.001 mg = 0.125 mg

1 ml of Digoxin elixir contains 0.05 mg

Now, find the milliliters needed for a day and then for a month:

x = 0.125 mg / 0.05 mg = 2.5 ml per day

For 30 days: 2.5 ml × 30 = 75 ml needed for a month.

B. For one - month supply 75 ml is needed. Explanation: First we have to convert mcg (microgram) to milligram (mg) by using the conversion factor as, 1 mcg = 0.001 mg So 125 mcg = 125 × 0.001 mg = 0.125 mg 1 ml of Digoxin elixir contains 0.05 mg Now we need to find the milliliters needed for a day and then for a month. x = 0.125 mg / 0.05 mg = 2.5 ml per day For 30 days we have to multiply 2.5 ml by 30 as, 2.5 ml × 30 = 75 ml is needed for a month.
