Question

Your patient gets a prescription for 62.5 mcg (micrograms, mg) of digoxin in liquid form. The label reads 0.0250 mg/mL. How many milliliters of digoxin should you give?

Answer 1

Answer:

2.5 militers (mL) of digoxin solution

Explanation:

if         1 microgram = 0.001 miligram

then   62.5 micrograms = X miligrams

X = (62.5 × 0.001) / 1 = 0.0625 miligrams

the we calculate the number of militers of digoxin needed by the patient:

if we have           0.0250 miligrams of digoxin in 1 mililiter of solution

then we have     0.0625 miligrams of digoxin in X mililiters of solution

X = (0.0625 × 1) / 0.0250 = 2.5 militers (mL) of digoxin solution
