Intake and output practice problems

Unit Conversion · 10 problems

Work each problem on paper first, rounding as the question says. Then open the answer to check it and see every step.

For study and exam practice, not for patient care. The orders in these problems are written for practice. In the clinic, follow the prescriber's order, your facility's protocols, and your pharmacy.

1. Problem 1

   The nurse is caring for a client during the day shift. The client drinks 10 ounces of tea, 8 ounces of coffee, 8 ounces of juice, and 10 ounces of water, and receives 0.9% sodium chloride IV at 50 mL/hr for 8 hours. Use 1 ounce = 30 mL. What is the client's total intake in mL? Record your answer using a whole number.

   Show answer and steps

   Answer: 1,480 mL

   1. Oral: 10 × 30 = 300 mL; 8 × 30 = 240 mL; 8 × 30 = 240 mL; 10 × 30 = 300 mL.

Record your answer using a whole number.

   Show answer and steps

   Answer: 1,920 mL

   1. Oral: 12 × 30 = 360 mL; 12 × 30 = 360 mL.
   2. IV: 100 mL/hr × 12 hours = 1,200 mL.
   3. Total intake = 360 + 360 + 1,200 = 1,920 mL.
