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.)
The Correct Answer is ["0.5"]
To administer the correct dose of vitamin K, which is 1 mg, the nurse should refer to the concentration of the available vitamin K injection.
The available concentration is 1 mg per 0.5 mL. Therefore, to deliver a dose of 1 mg, the nurse needs to administer 0.5 mL. When rounding to the nearest tenth, the amount remains 0.5 mL.
