Injectables and liquid oral - For answers of less than one milliliter: Since the 1 mL syringe is calibrated in ______ increments, the answer should be expressed in 100ths. If the math calculation does not work out evenly to the 100th place, then the division is carried to the 1000th place and rounded to the 100th place. for ex. 0.876 would be 0.88.
100th mL
Injectables and liquid oral - For answers of greater than one milliliter: Since 3-6 mL syringes are calibrated in ______ increments, answers should be expressed in 10ths. If the math calculation does not work out evenly to the10th place, then carry division to the 100th place and round to the nearest 10th.
Example: 1.75 mL = 1.8 mL

Rates for IV fluids are expressed in _________ (gtt/min) when an infusion device is not used or mL/hr when an infusion device is used. If the math calculation does not work out evenly to a whole number, then the division is carried to the 10th place and rounded to a whole number.

Whole numbers

o Example: 166.6 mL/hr = 167 mL/hr
