Can you give this dosage?
If yes, how many mL do you give?
Answers :
Step by step calculation :
Step 1 :
convert lbs to kg
1 pound =0.45 kg
So, Patient weight = 67 kg
Step 2 :
Available dose 1 g / 4 ml
1g= 1000 mg
1000 mg = 4 ml
1 ml = ?
1 ml = 1000 / 4
Hence , 1 ml = 250 mg
Step 3 :
Prescribed dose 15/kg/day
Patient dose = 15 mg x 67 kg
Hence, Per day = 1005 mg /per day
Step 3 :
Formula :
Amount want to give = desired dose / quantity in hand
= 1005 / 250
= 4.02 ml
Hence , answer is 4.02 ml to be given.
