Input math question

Can someone help me with this question. I have the answer already I just need help with working it out? Like showing all the work so I can try and understand where I went wrong. This is my first med surge class and this was a study question in ATI online. But it didn't show me how the get the right answer.


Feb 22Calculate total number milliliters of fluid a client received in a 9 hour major abdominal surgery. What is total milliliters of fluid.
Lactated ringers 150ml/hr
Cefazolin sodium (ancef) 2gm iv with piggy back in 200ml normal saline
2units of packed rbcs @ 275 ml and 250 ml
Bolus of 250ml normal saline every 4 hrs
Ranitide (Zantac) 50mg iv in 50ml DSW over 30 minutes
Answer is 2525 mL. But how?? 
Feb 22This is simple addition. But you're right, I don't get that answer also. There are mistakes in textbooks sometimes.


Feb 22I just found this question on ATI it states "Cefazolin sodium (ancef) 2gm iv with piggy back in 100ml normal saline" not 200 so I got the right answer.

Feb 22Basically you just add up the numbers. The first one is LR at 150/hr which comes to a total of 1350 for the total 9 hour surgery.
then the next. 
Feb 22Lactated ringers 150ml/hr (150*9=1350)
Cefazolin sodium (ancef) 2gm iv with piggy back in 100ml normal saline
2units of packed rbcs @ 275 ml and 250 ml
Bolus of 250ml normal saline every 4 hrs
Ranitide (Zantac) 50mg iv in 50ml DSW over 30 minutes
Answer is 2525 mL. 1350+100+275+250+250+250+50=2525 



Feb 22So nothing had to be converted over?! Like the units measured by? I guess I'm just over thinking all of this! Med surg has been over whelming last 2 weeks!

Feb 22So this ... Cefazolin sodium (ancef) 2gm iv with piggy back in 100ml normal saline.... it's just 100 ml. I don't need to add in the 2gm or whatever that is?!
