To determine how many milliliters to give, use this formula: Desired amount/Available amount × Quantity. Therefore, 9 mg/4 mg × 1 mL = 2.25 mL. The correct syringe to select for this injection is a 3 mL. The markings on a 3-mL syringe are to the nearest tenth. When this syringe is used, carry out the decimals two places and round off to the nearest tenth for milliliters. In rounding off numbers, when the last number is 5 or more, add 1 to the previous number, and when the last number is 4 or less, drop that number. Therefore, 2.25 = 2.3 mL.
