Fundamentals Question #12

Question

The nurse is calculating intake and output from 0700-1700. The client has an IV infusing at 75 mL/hr. For breakfast the client has: an 8 oz. cup of coffee, 3 tsp. of gelatin, a 30 oz. cup of ice, and 240 mL of orange juice. At lunch the client has 8 oz. tea, an 8 oz. chicken patty and 6 oz cola. How­ many mL will the nurse record as intake?

The family reports emptying 12 oz., 18 oz. and 5 oz. from the urinal. The client also vomits 800 mL of emesis. How many mL will the nurse record as output?

Overview

Correct calculation of intake and output is an important responsibility of the nurse. The total intake is 1775 mL and the total output is 1850 mL.

The correct answer for Intake is = 1775 mL

IV fluids 75 mL x 10 hours = 750 mL

8 oz coffee   8 x 30 mL = 240 mL

3 tsp of gelatin 3 x 5mL = 15 mL

30 oz of ice (*this counts half) 30/2= 15 x 30 mL = 450 mL

240 mL of orange juice = 240 mL

6 oz cola      6x 30 mL = 180 mL

*The chicken patty is not liquid and will not be calculated in I & O

The correct answer for Output is = 1850 mL

12 x 30 mL = 360 mL

18 x 30 mL = 540 mL

5 x 30 mL = 150 mL

800 mL of vomitus

Explanation

Learning Outcomes

Intake fluid calculation includes any fluid a client takes into their body, including their mouth, by IV, by a feeding tube (nasogastric tube or other gastric tubes), or by other catheters placed in the body. Output fluid calculation includes anything fluid a client has removed from their body, including urine, vomitus, suctioning, and drainage from procedures or drains. Correct calculation of intake and output is an important responsibility of the nurse. The total intake is 1775 mL and the total output is 1850 mL. This indicates slightly more fluid has left the body compared to what the client has taken in.

Test Taking Tip

Remember ice always counts as ½, for example 8 oz of ice = 4 oz of intake or 120 mL.
