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.

Correct Answer is ["A","B","D","E"]
Explanation
Choice A rationale
Calculating the safe dosage is a crucial step in administering medication to a toddler. This ensures that the child receives the appropriate amount of medication based on their weight and age.
Choice B rationale
Identifying the toddler by asking the caregiver is an important step to ensure that the correct medication is given to the correct child.
Choice C rationale
Telling the caregiver to administer the medication is not recommended. As a nurse, it is your responsibility to administer the medication to ensure it is done correctly.
Choice D rationale
Offering juice after the medication can help mask any unpleasant taste and make the medication administration process more tolerable for the toddler.
Choice E rationale
Asking the toddler to pick a toy to hold during administration can serve as a distraction and make the process less stressful for the child.
Correct Answer is C
Explanation
Choice A rationale
Inserting medication in the buccal cavity is an appropriate method for administering oral medication to an infant. The buccal cavity is the area between the cheek and gums, and medication placed here is absorbed directly into the bloodstream.
Choice B rationale
Wrapping the infant in a blanket can provide comfort and security during medication administration, making it easier for both the parent and the infant.
Choice C rationale
Positioning the infant in a supine position during oral medication administration is not safe. This position increases the risk of aspiration, which can lead to choking.
Choice D rationale
Administering medication with an oral syringe is an appropriate method for giving oral medication to an infant. It allows for accurate dosing and can be directed towards the cheek to prevent choking.
