Calculating
Intake and Output
| In
the pediatric population, generally we are concerned about the total
intake the client receives per day. Output is equally important.
Therefore, all fluids are calculated for infants, small children,
and others whose fluid balance status is of concern.
Example: John's primary IV is running at 34 ml/hr while NPO. When the nurse runs the Vancomycin (250 mg IV q 8 hr) in over 90 minutes [volume is 100 ml--(2 50 ml syringes)], the primary IV is stopped. The ampicillin (395 mg IV q 6 hr) is given concurrently in 10 ml of fluid over 30 minutes. He received 2 boluses of aminophylline (20 ml each over 20 minutes). The IV fluids were stopped while the aminophylline infused. Since microtubing was used for the medications, total flush is negligible (approximately 3 ml). What is John’s total intake for 24 hours?Calculate using the critical information:

To calculate how much IV fluids a child should receive per day, use the following guide:
| < 10 kg | 100 ml / kg |
|
. |
< 10 kg or less, multiply child's weight x 100 |
| > 10 kg < 20 kg | 1000 + (50 ml / kg for # kg > 10) |
| . | 10 kg = 1000 + (Subtract 10 from child's weight, multiply that x 50.) |
| > 20 kg | 1500 + (20 ml / kg for # kg > 20) |
| . | 20 kg = 1500 + (Subtract 20 from child's weight, multiply that x 20.) |
| 5.4 kg | = | 5.4 x 100 = 540 ml/day |
| 11.3 kg | = | 1000 + (11.3 - 10 = 1.3 x 50) 1000 + 65 = 1065 |
| 27 kg | = | 1500 + (27 - 20 =7 x 20) 1500 + 140 = 1640 |
| Calculating
total I & O
Example: Crystal has an IV infusing at KVO (10 ml/hr). She receives an antibiotic in 22.5 ml q 8° concurrently. One ml flush is given after each antibiotic. She is given 30 ml of formula q 3°.Calculate her I & O for the past 24 hours. Intake:
Output:
If Crystal weighs 5.0 kg, what is her average urinary output over the past 24 hours?
