Quizplus · Accepted Answer

To determine how many milliliters to give, use this formula: Desired amount/Available amount × Quantity. Therefore, 75 mg/50 mg × 1 mL = 1.5 mL. The correct syringe to select for this injection is 3 mL because the amount to give is greater than 1 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.
