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.
