Intake and Output: Equivalent Measurements 1 glass 8 ounces 240 mL 1 cup 8 ounces 240 mL 1 teacup 6 ounces 180 mL 1 styrofoam cup 6 ounces 180 mL 1 popsicle 3 ounces 90 mL Ice Cubes Melt to ½ the original value 700 mL of ice cubes 350 mL of fluid intake 1 ounce (oz) 30 mL 1 tablespoon (T, Tbs) 15 mL 1 teaspoon (t, tsp) 5 mL KEY POINTS: ● Intake and output (I&O) are calculated in mL. ● The size of food containers varies, so it is important for the nurse to become familiar with the specific containers used in each clinical setting. ● Parenteral intake is calculated as a part of the total intake. Working With Intake and Output Add the following intakes and outputs. 1. The patient is on strict I & O. For breakfast, the patient took 1 cup of coffee, a 4 ounce glass of juice, and 240 mL of milk. For lunch, the patient had a styrofoam cup of tea and 6 ounces of broth. The patient voided 260 mL at 1000, and 180 mL at 1400. Calculate the patients I&O. I: 960 mL O: 440 mL 2. The patient is NPO for breakfast. For lunch, the patient was allowed to take 120 mL of water. The patient vomited 180 mL at 1300 and voided 100 mL at 1330. At 1400, the patient took 2 T of JELL-O® and ½ glass of apple juice. Calculate the patient’s I&O. I:270 mL O: 280 mL 3. The patient has a NG tube connected to low wall suction. At 0930, the MD wrote an order to clamp the NG tube. The nurse emptied 280 mL of NG drainage. At 1100, the patient vomited 325 mL of bile-colored drainage. The NG tube was reconnected to suction and drained an additional 475 mL by the end of the shift. The patient’s wound drainage tube collected 60 mL of serosanguineous fluid. The patient's indwelling urinary catheter drained 270 mL of dark amber urine. Calculate the patient’s output. O: 1410 mL 4. A patient who had prostate surgery yesterday has an indwelling urinary catheter with a continuous bladder irrigation. He is NPO for breakfast and is started on a clear liquid diet for lunch. He took 6 ounces of broth and 4 ounces of cranberry juice. By the end of the shift, the nurse calculates that 2000 mL of bladder irrigant has infused. The total amount emptied from the urinary bag was 2270 mL. Calculate the I&O. I: 300 mL O: 270 mL The next sample of questions are for I&O for patients receiving IV infusions. This is optional for working through these questions as the level of difficulty is increasing with them. In theory, you are just practicing how to calculate I&O’s and therefore this content has been added for those that wish to be challenged and continue using more critical thinking in application. Key Terms: D5W= Dextrose 5% in water NS= 0.9% Sodium Chloride/ Normal Saline D5NS= Dextrose 5% with Normal Saline D51/2NS= Dextrose 5% with ½ or 0.45% of Sodium Chloride/Normal Saline LR= Lactated Ringer KCL= Potassium Chloride 1/2NS= 0.45% Sodium Chloride/Normal Saline PRBC= Packed Red Blood Cells 5. The patient has an IV of D5W infusing at 125 mL/hr. For breakfast, the patient took 1 glass of juice and a cup of coffee. For lunch, the patient took six ounces of soup and a 12 ounce can of soda. The patient voided 220 mL at 1000 and 375 mL at 1400. Calculate the patient’s 8-hr total I&O. I: 2020 mL O: 1000 mL 6. At 0700, the patient is NPO and has a primary IV of 1 L of D5NS Q10H, infusing continuously. The patient receives gentamicin 80 mg IVPB in 100 mL NS at 0900-1700-0100, and Metronidazole 500 mg in 100 mL in NS at 0800. Calculate the patient’s total parenteral intake starting at 0700 and ending at 1500. I:1000 mL 7. At 0700, the nurse started an IV of 1 L LR and set the infusion pump at 83 mL/Hr. The patient was put on strict I&O. The patient was started on Famotidine 20 mg IVPB in 50 mL NS, at 0800 and 2000. For breakfast, the patient took 1 cup of coffee and a 6 ounce bowl of creamy oatmeal. He was NPO except for ice chips for the rest of the shift. The patient took 6 ounces of ice chips and voided 425 mL. Calculate the patient’s total I&O starting at 0700 and ending at 1500. I: 1224 mL O: 425 mL 8. At 1500, the patient had an IV of 1 L of D5W infusing at 125 mL/hr. For dinner, the patient took 1 glass of juice and an 8 ounce can of nutritional supplement. The IV infiltrated at 1800 and was restarted at 2000. The patient received KCL 20 mEq IVPB in 100 mL D5W at 1700. The patient voided twice for the entire shift (325 mL and 290 mL). Calculate the patient’s total I&O starting at 1500 and ending at 2300. I:1330 mL O: 605 mL 9. At 2300, the patient had an IV of 1 L of 0.45% NS infusing at 50 mL/HR. The patient had coffee-ground emesis measuring 480 mL at 0100. The MD ordered 2 units of PRBCs over 3 hours. Followed by an IV of 0.9% NS, to infuse at 150 mL/HR. The nurse discontinued the current IV and started the first unit of PRBC (250 mL) at 0200, and the second unit (270 mL) at 0330. The IV of 0.9% NS was started at 0500. Calculate the patient’s total I&O starting at 2300 and ending at 0700. I: 970 mL O: 480 mL 10. At 1500, the patient had 900 mL left in the IV bag. The IV was infusing at 75 mL/HR at 1900, the IV infiltrated and was restarted 1 hour later. The physician increased the IV rate to 125 mL/HR at 2000. Calculate the patient’s total parenteral intake starting at 1500 and ending at 2300. I: 675 mL 11. At 0700, the MD ordered 1 L of D5/0.45% NS to infuse at 75 mL/HR for the first 3 hours, and then at 125 mL continuously. For breakfast, the patient took 1 cup of coffee, 8 ounces of milk and 6 ounces of orange juice. The patient voided 50 mL at 0900, and 75 mL at 1000. At 1100, the nurse inserted a Foley catheter pr MD order and obtained 425 mL of urine. For lunch, the patient only took 5 ounces of broth. The nurse empied the Foley catheter at 1500 and obtained 250 mL. Calculate the patient’s total I&O starting at 0700 and ending at 1500. I: 1660 mL O: 800 mL 12. At 0900, the nurse begins the care of a patient who has just been transferred from the post-anesthesia care unit. The patient has a new liter of D5/0.9% NS infusing at 125 mL/HR. The patient has an indwelling urinary catheter with continuous bladder irrigation of NS infusing at 75 mL/HR to keep the catheter free of clots. At 1500, the nurse empties 1575 mL from the urinary catheter. Calculate the patient’s total I&O starting at 0900 and ending at 1500. I: 750 mL O: 1125 mL 13. At 2300, the patient had 850 mL left in the IV bag. The IV was infusing at 50 mL/HR. At 0200, the IV infiltrated and was restarted 2 hours later. The physician increased the IV rate to 75 mL/HR at 0400. Calculate the patient’s total parenteral intake starting at 2300 and ending at 0700. I: 375 mL
