Peds math

:uhoh3: I need help on a math question. Here it is:

A 22 kg 8 yr old child with herpes has the following orders:

IV of D5.25 NS at 14 mL/hr

Acyclovir (5mg/mL) 100 mg IV every 8hr. Give over 1 hour

:confused: What is the calculated medication VTBI?

:eek: My book says to use this formula D/H x Q? 100/5 x 1 = 20, but the the total for the day is 1320 mg. Wouldn't I just divide this by 3 to get the medication per dose? SO CONFUSED! Then, is this safe?

My guide says:

- 15-60 mg/kg/day divided by q8h

- infusion time II: 60 min

- final concentartion for infusion after reconstitution not to exceed 7 mg/ml

- compatible w/ D5W, NaCl solutions and LR
