A nurse is preparing to administer vitamin K 1mg IM to a newborn.
The available vitamin K injection is 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"]
Step 1: The nurse needs to administer 1mg of vitamin K. The available vitamin K injection is 1 mg per 0.5 mL.
Step 2: To find out how many mL the nurse should administer, we divide the required dose by the concentration of the injection. So, 1 mg ÷ (1 mg/0.5 mL).
Step 3: This simplifies to 1 mg × (0.5 mL/1 mg).
Step 4: The mg units cancel out, leaving us with 0.5 mL. So, the nurse should administer 0.5 mL of the vitamin K injection per dose.
