A nurse is preparing to administer cyanocobalamin 100 mcg IM monthly. Available is cyanocobalamin injection 1,000 mcg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Identify the given information: Dose of cyanocobalamin: 100 mcg Concentration of cyanocobalamin injection: 1,000 mcg/mL Calculate the volume of cyanocobalamin injection to be administered: Volume = Dose (mcg) / Concentration (mcg/mL) Substitute the values: Volume = 100 mcg / 1,000 mcg/mL Volume = 0.1 mL
