Answer:
Step-by-step explanation:
I'm only like 60% sure so you might want to double check this.
Think:
Need 400 mg
Have 100 mg per mL ( Need four times that amount )
Calculate:
Dosage on hand Dosage desired
=
Amount on hand X Amount desired
Cross multiply 100 mg 400 mg
1 mL X =mL
100 X = 400
100 X = 400
Simplify ----------------------
100 100
X 4 mL
Withdraw 4 mL of reconstituted Zithromax using 5 mL syringe
Further dilute and give IV
Since single-dose vial, discard any remaining drug
Hopefully this helps!
