he physician orders Gentamicin 5 mg/kg/dose. The patient weighs 165 pounds. Gentamicin is available as 20 mg/2 mL. How many mL will each dose contain?
ANSWER.
* Calculation of volume(ml) of drug per dose.
Formula = Desired dose/Dose in hand * Quantity.
Here
Ordered dose = 5 mg/kg/dose.
Weight of the patient = 165 pounds.
Convert pound to kg for calculation
1 pound = 0.454 kg.
So
Weight of the patient = 165 * 0.454
= 74.9 kg.
Desired dose(D) = 5 * 74.9
= 374.5 mg.
Dose in hand (H) = 20 mg.
Quantity (Q) = 2 ml.
As per above formula
Volume(ml) of drug per dose = D/H * Q
= 374.5 / 20 * 2
= 18.73 * 2
= 37.5 ml per dose.
