- IV rate calculations will be rounded to nearest whole number.
Adult calculations: the calculation will be rounded to the nearest tenth. Drug Calculation safety considerations:
- Examples:
- 5 must be answered as 0.5
- 5.0 must be answered as 5
- To promote safety, a zero must be placed to the left of the decimal point in answers that are less than one. No zero is allowed to the right of the decimal point in answers that are whole numbers.
- Labeling is not necessary

Correct Answer is ["2070"," 1440"]
Explanation
The calculation is as follows:
Intake = (20 + 10 + 15) mL x 3 (medication and flushes) + 240 mL (water intake) + 150 mL/h x 6 h (IV infusion) = 2070 mL
Output = 320 mL (Hemovac drainage) + 210 mL (chest tube drainage) + (275 + 325 + 310) mL (urine output) = 1440 mL
