A nurse is preparing to administer fentanyl 100 mcg IM one time for pain to a client who is in labor and requests pain medication. Available is fentanyl injection 0.05 mg/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.)

Available dose: 0.05 mg/mL Conversion of mcg to mg 1 mg = 1000 mcg Given 0.05mg (0.05mg × 1000mcg)/1mg Therefore 0.05 mg = 50mcg Available dose: 50 mcg/mL Ordered dose: 100 mcg Formula: Dose to administer (mL) = Ordered dose (mcg) / Available dose (mcg/mL) Given: Volume (mL) = 100 mcg / 50 mcg/mL = 2 mL The nurse will administer 2 mL of fentanyl.
