Please Help Student Nurse With Peds Math!!

  1. Hi everyone! Im hoping someone can help me...Ive been sitting here for hours and my mind is smoking!!! AHHHHH! Im doing my Peds rotation and I have to do a report on a patient and I cant figure out the math!!!!! Heres the info:

    Pt is 33 months old. 36 inches, 31 lbs. (68 kg.)
    One of the questions is askng to list the meds theyre taking and then calculate the patients safe dose range in 24 hours. The meds are:
    Ampicillin 100 mg/kg/day 350 reg IV q6h <-- the 350 reg IV confused me but thats how it was written
    Nysatin 100,000 u/ml to white plaque QID
    How in the heck do I figure it out?

    The next question asks:
    Calculate the pts 24 hour fluid needs, and hourly fluid needs. Include the rate if patient is receiving IV fluids. Heres what i got to so far:
    10 x 100 = 1000
    10 x 50= 500
    48 x 20 = 960 The answers total 2460 ml/24 hours
    Then I divided 2460 by 24 and got 102.5 ml/hour.

    Am i correct in that part? But what do they mean by including the rate for the IV????
    If anyone can help me I think Ill cry tears of joy!! I appreciate it sooooooooooooooooooooooooooooooooooooooooooooooooo oooooooooooooooooooooooooooooooooooooooooooooooo much!

    Thank you!!!!!!!!

    Start by dividing the weight in pounds x 2.2 to get the kg.

    31 divided by 2.2 gives you a weight of 14kg.

    this may help you in your other calculations.

    lbs to kg....divide by 2.2

    kg to lbs....multiply by 2.2
