1. Using the correct vial, calculate the volume of the medication that you need to compound one IVPB bag
2. The patient is 6’ 2”, weighs 198 lbs, and is receiving gentamicin 140 mg IV Q8H. Based on this prescription, calculate this dose in mg/kg/day. Round your answer to one decimal point.

Answer:

Answer 1

1)Gentamycin vial

Available 800mg=20ml

Then 140mg=??

=3.5ml (cross multiply and divide 140×20÷800)

3.5ml of medication has to be compounded in one IVBP Zbag

2)Given

Height :6'2"(187.9cm)

Weight :198Ibs(89.8kg)

Ordered dose mg

Frequency::Q8H ( 8 hourly)

Route:IV

To calculate the dose in mg/kg/day

As 140 mg to be administered for 89.9 kg as one time dose in a day three doses will be administered over 24 hours (140×3= 420mg/day to be administered )

when 140mg=89.9kg

Then 1kg=??

1.55mg (140×1÷89.9) or 1.5

So 1.5mg/kg/day to be administered
