.A nurse is preparing to administer vitamin K 1mg IM to a newborn. Available is vitamin K injection 1 mg/0.5 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.)

To determine the correct volume to administer, we use the formula for calculating the dose: Volume to administer=Prescribed dose ÷ Available concentration Given: ● Prescribed dose: 1 mg ● Available concentration: 1 mg per 0.5 mL Plugging in the values: Volume to administer=1 mg÷ 1 mg/0.5 ml Perform the division: Volume to administer=0.5 mL So, the nurse should administer 0.5 mL per dose. Since the question specifies rounding to the nearest tenth and to use a leading zero if it applies (and not to use a trailing zero), the final answer is: 0.5 mL
