Question

I just want to check my answers!

1) Ordered amoxicillin 375mg PO. The supply on hand is an oral suspension of 125mg/5mL.

How many mL would you administer?

2) The label on the vial states the concentration of a drug is 50 mg/mL. If you draw up 1.5mL into your syringe, how many mg will you be administering?

3) Digoxin 100mcg is ordered. The vial label indicates a concentration of 0.5mg/2mL. What volume of medication will you administer to give the correct dosage?

4) Flagyi 0.75g PO has been ordered and you have 500mg tablets. How many tablets should you administer to receive the prescribed dose?

Answer 1

1) 125:5::375:x

x=(375)(5)/125=15

15 ml

2)50:1::y:1.5

y=(50)(1.5)=75

75 mg

3)100mcg=0.1mg

Please recheck this question looks like a number or an unit is not correct

4)1g=1000mg

1:1000::0.75:z

z=(1000)(0.75)=750

750mg

500+250= one and a half tablet
