Calculating Intake and Output

Hello. I was wondering if anyone could help me solve intake and output problems. I found two online and have been trying to solve them, but I don't understand what I am doing wrong. I posted my work below. Thanks.

Calculate the patients INTAKE during your 12-hour shift:

0800: Two pieces of toast, 2 cups of oatmeal, 8 oz yogurt, 12 oz orange juice, 2 oz grits—

1000: Two 8 oz of coffee w/ 2 oz of cream in each—

1100: 24 oz of ice chips—

1200: IV infusion of Zosyn 50 mL, 2 mL IV push Zofran and 10 cc saline IV flush—

1230: house salad, 12 oz soda, three 12 oz popsicles—

1400: One pack of red blood cells (250 mL)—

1500: 2 mL Morphine and 10 cc saline flush IV—

1715: 10 cc saline flush IV—

1600-1900: Normal Saline IV 100 cc/hr

A.  2390 mL

B.  2124 mL

C.  3394 mL

D. 3294 mL

My Work:

12 + 8+8+2+2+(24/2)+12+(12*3)=92*30=2760

50+2+10+250+2+10+10+(100*12)=1,534

1534+2760=4294 total

Problem 2

Estimate the patients 8 hour (3pm-11pm) intake:

IVF @ 25cc/hr continuous

TPN @ 50cc/hr continuous

Lipids at 10cc/hr for 12 hours (8pm-8am)

NGT feeds @ 25 cc/hr continuous

2 units of blood – 250ml/unit – first unit at 10am/ second unit at 4pm

IV Vancomycin – 250ml every 12 hours at 8am/8pm

My Work:

(25*8)+(50*8)+(10*12)+(25*8)=920

250+250=500*30=15,000

15,000+920=15,920
