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 B

Explanation

Choice A rationale

Adjusting the harness straps every day is not recommended. The straps should be adjusted only as directed by the healthcare provider or orthopedic specialist to ensure proper positioning and effectiveness of the Pavlik harness.

Choice B rationale

This is the correct answer. Checking the baby’s skin three times a day is important to prevent skin irritation or breakdown under the harness.

Choice C rationale

Massaging lotion on the skin around the harness clasps is not recommended as it can cause skin irritation.

Choice D rationale

The diaper should be placed under the harness to prevent soiling and maintain the effectiveness of the harness.

A. Bulging fontanel. B. Insomnia. C. Low-pitched cry. D. Positive Babinski reflex.

Correct Answer is A

Explanation

Choice A rationale

A bulging fontanel is a common sign of increased intracranial pressure (ICP) in infants. The fontanels, or soft spots on an infant’s head, allow for brain growth. When there is increased pressure, as in conditions that cause increased ICP, it can cause the fontanels to bulge outwards.

Choice B rationale

Insomnia is not typically associated with increased ICP in infants. Changes in consciousness, such as irritability or lethargy, may be seen, but these are not the same as insomnia.

Choice C rationale

A low-pitched cry is not typically associated with increased ICP in infants. Changes in cry might occur, but they are not specific to increased ICP4.

Choice D rationale

A positive Babinski reflex is normal in infants up to about 12 months of age. It is not specifically associated with increased ICP4.
