A client receives a prescription for penicillin 2 million units IM. The available vial is labeled, "600,000 units/2 mL." How many mL should the nurse administer? (Enter numeric value only.)

We will solve this step by step. Step 1: Write down what is given Prescribed dose: 2,000,000 units Vial concentration: 600,000 units / 2 mL Step 2: Determine how many units are in 1 mL Units per mL = 600,000 units/ 2 mL = 300,000 units/mL Step 3: Use the formula to calculate mL to administer Volume to administer (mL) = Prescribed dose (units) / Concentration (units/mL) Volume to administer (mL) = 2,000,00/ 300,000 = 6.6667 mL =6.6667 mL Step 4: Round appropriately Rounded to 2 decimal places: 6.67 mL Numeric value: 7mL
