Input math question

[derfashley]

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.

Sure, where's the question?

Calculate 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??

This is simple addition. But you're right, I don't get that answer also. There are mistakes in textbooks sometimes.

I got 2625

I 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.

Basically 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.

Lactated 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

The bolus of NS is counted twice because its every 4 hours.

Does that make sense? Any questions?

[derfashley]

Yes it's 100 my mistake! Thanks

So 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!
