When solving any problem, first check that the order and the supply are in the same weight measure. For this problem, no equivalent is necessary. Estimate the amount to give. Dimensional Analysis: 1 mL/2 mg * 3 mg = 1 mL * 3/2 = 3/2 = 1.5 mL. The correct syringe to select for this injection is a 3 mL. The markings are to the nearest tenth. The 1-mL syringe is used for a maximum volume of 1 mL of medication. Insulin syringes are used only for insulin administration. The markings are in units.
