need help calculating fluid balance

[youngin14]

Hi there, I am stuck on a pediatric homework question and having trouble grasping this..Does the 20cc/hr IV line change when the meds are running? If so how much do you put it down/ what is the rationale? How do I calculate the IV for each lumen? or does the solution not run while the med is running?

-Pt has a double lumen hickman with D5/9 + 10KCL going into each luman at 20cc/hr

2200- 24ml Ondanseon into blue lumen over 1/2 hour + 3ml flush

2400- 3.6 ml Tobramycin into red lumen over 1/2hour + 3 ml flush

0100- 10 ml Vancomycin into blue lumenover 1 hour + 3 ml flush

Time IV meds Red Lumen IV Blue Lumen IV

2100 hrs 0 20 20

2200 hrs

Thank you very much!

You have solution running in each lumen at the same rate.

If if meds are compatible with those solutions you just run them without changing the rate of the already hanging solution.

Do your multiplication and addition and show us what you get. Are you doing daily fluids such as ml/kg/day? Or just once shift? It looks

like some info may be missing.

thanks for the reply!

So i talked to my professor and they gave us a hint that we turn each maintenance IV down to 10ml/hr while a secondary med is infusing and most flushes take 4 minutes. How did they know to get 10 ml/hr though??

2200- Ondansetron= 27 ml total over 1/2 hour and 4 minute flush=34 minutes= 60 min/hr-34min=26 / 60 =0.43 then do i multiply this by the normal maintenance rate (20) or by the 10 I have apparently turned the IV down to?

if it is by 20 then it is 8.6, if it is by 10 it is 4.3

so then to write it in the fluid balance chart would it be:

time:

2200

Iv Med: 27ml ( with the slash through the box to only take up 34 minutes)

IV Rate: 4.3 (would it be in the top half of the hourly box? if so what goes in the bottom? is it 10-4.3= 5.7).

Sorry for all the questions I am super confused!
