Ordered: Digoxin 250mcg. Available: 0.125/10mL. How much medication should the patient receive (mL)?
ANSWER.
* Calculation of volume(ml) of drug required.
Volume(ml) = Desired dose(D)/Dose in hand(H) * Quantity(Q)
Here
Desired dose(D) = 250 mcg.
Dose in hand(H) = 0.125 mg.
Convert mg to mcg for calculation
1 mg = 1000 mcg
So
Dose in hand(H) = 0.125 * 1000
= 125 mcg.
Quantity(Q) = 10 ml.
As per above formula
Volume(ml) of drug required = D/H * Q
= 250/125 * 10
= 2 * 10
= 20 ml.
