mL
Explanation & Rationale
Calculation Steps Step 1: Identify the concentration of the medication in the syringe. The syringe is labeled “Enoxaparin sodium injection, USP 60 mg/0.6 mL.” Step 2: Calculate the amount of medication per mL. 60 mg ÷ 0.6 mL = 100 mg/mL Result = 100 mg/mL Step 3: Determine the prescribed dose. The prescribed dose is 80 mg. Step 4: Calculate the volume to administer. 80 mg ÷ 100 mg/mL = 0.8 mL Result = 0.8 mL Therefore, the nurse should administer 0.8 mL.
