ANSWER.
* Calculation of volume(ml) of drug required.
Formula
Volume(ml) = Desired dose(D)/Dose in hand(H) * Quantity(Q)
Here
Desired dose(D) = 2000 mg (2 gm)
Dose in hand(H) = 250 mg.
Quantity(Q) = 1.5 ml
As per above formula
Volume(ml) of drug required = D/H * Q
= 2000/250 * 1.5
= 8 * 1.5
= 12 ml.
6) Patient weight in kg.
Weight of the patient in pounds = 175 pounds.
1 pound = 0.454 kg
So
Weight of the patient in kg = 175 * 0.454
= 79.45
= 79.5 kg.
7) Minimum mg of amount allowed for this patient per dose.
Allowed minimum dose = 200 mg/kg/day (every 6 hrs).
Weight of the patient = 79.5 kg (175 pounds)
Every 6 hours means 4 times a day (6 * 4 = 24hr).
So
Allowed minimum dose for patient weight 79.5 kg = 200 * 79.5 / 4
= 15900 / 4
= 3975 mg per dose.
8) Maximum number of mg allowed for this patient per dose.
Allowed maximum dose = 300 mg/kg/day (every 6hr).
Weight of the patient = 79.5 kg.
Every 6hr means 4 times a day (6*4 = 24hr)
So
Allowed maximum dose for patient weight 79.5 kg = 300 * 79.5 / 4
= 23850/4
= 5962.5 mg per dose.
