The healthcare provider prescribes cyanocobalamin injection 100 mcg IM every 3 days for a client with pernicious anemia. The vial is labeled, "1 mg/mL." How many mL should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)

Given Information: Prescribed dose: 100 mcg Concentration: 1 mg/mL Convert the prescribed dose to milligrams: 100 mcg = 0.1 mg Calculate the volume to be administered Volume to be administered = Prescribed dose (in mg) / Concentration Volume to be administered = 0.1 mg / 1 mg/mL = 0.1 mL
