Question

Digoxin is available in a concentration of 0.1 mg/ml. How many ml are required to administer a 75 mcg dose?

Answer 1

Answer : The volume required to administer a 75 mcg dose are, 0.75 mL

Explanation : Given,

Concentration of Digoxin = 0.1 mg/mL

That means, 0.1 mg of Digoxin present in 1 mL of solution.

Mass of dose = 75 mcg = 0.075 mg

Conversion used : (1 mcg = 0.001 mg)

Now we have to determine the volume required to administer a 75 mcg dose.

As, 0.1 mg of Digoxin required in 1 mL of solution

So, 0.075 mg of Digoxin required in $\frac{0.075mg}{0.1mg}\times 1mL=0.75mL$ of solution

Thus, the volume required to administer a 75 mcg dose are, 0.75 mL
