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.)

Answer and Explanation

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 C

Explanation

Choice A rationale

Applying suction continuously while inserting the suction catheter is not recommended. This could potentially cause trauma to the trachea and lead to complications.

Choice B rationale

Using a large diameter suction catheter for better suctioning is not recommended. The size of the suction catheter should be appropriate for the size of the tracheostomy tube. Using a catheter that is too large could cause trauma to the trachea.

Choice C rationale

Suctioning for no more than 10 seconds at a time is recommended to prevent hypoxia (lack of oxygen). Prolonged suctioning can lead to complications such as hypoxia, trauma to the trachea, and cardiac arrhythmias.

Choice D rationale

Applying suction while the child is exhaling is not recommended. Suction should be applied while withdrawing the suction catheter, not during exhalation.

A. “Your child needs to rest.”. B. “You should expect your child to be upset when you leave.”. C. “I will notify the provider of his behavior.”. D. “Your child is responding to an overstimulating environment.”.

Correct Answer is B

Explanation

Choice A rationale

While rest is important for a child, suggesting that the child needs to rest does not address the parents’ concern about their child crying when they leave.

Choice B rationale

This is the correct answer. It is normal for an 8-month-old child to show signs of separation anxiety when their parents leave. This is a part of their normal development where they start to understand object permanence - the concept that things and people exist even when they’re out of sight. This can make them upset when their parents leave as they understand their parents are somewhere else, but they don’t know when they’ll return.

Choice C rationale

Notifying the provider about a normal developmental behavior is not necessary. It’s important for parents to understand that this behavior is a normal part of their child’s development.

Choice D rationale

While an overstimulating environment can cause distress in children, in this case, the child is upset because of their parents leaving, not because of the environment.
