A nurse is preparing to administer 50 mcg of fentanyl to a client who is in labor. The amount available is 100 mcg per 2 mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Calculation: Identify the ordered dose and available concentration Ordered Dose: 50 mcg Available Concentration: 100 mcg/2 mL Calculate the volume to administer Volume to administer = (Ordered Dose ÷ Concentration) × Volume of Concentration Volume to administer = (50 ÷ 100) × 2 Volume to administer = 0.5 × 2 Volume to administer = 1 mL
