A nurse is collecting data from an infant at a well-child visit.
The nurse should expect the infant to double his birth weight by which of the following ages?

3 months.

6 months.

9 months.

12 months.

Answer and Explanation

The Correct Answer is B

Choice A rationale

While some babies may experience rapid growth and double their birth weight within the first 3 months, this is not typically expected. Most infants are expected to double their birth weight by 5 to 6 months of age.

Choice B rationale

Most infants are expected to double their birth weight by 5 to 6 months of age. Therefore, by the age of 6 months, it would be expected for an infant to have doubled their birth weight.

Choice C rationale

By 9 months, most infants would have already doubled their birth weight. The typical expectation is for infants to double their birth weight by 5 to 6 months of age.

Choice D rationale

By 12 months, most infants would have already doubled their birth weight and are on their way to tripling their birth weight. Therefore, expecting an infant to double their birth weight by 12 months would be beyond the typical timeframe.

Correct Answer is C

Explanation

The correct answer is C. When administering an oral elixir to a 3-month-old infant using an oral medication syringe, the nurse should position the syringe to the side of the infant’s tongue. This prevents the medication from being administered too quickly and reduces the risk of choking.

A. Ask another nurse to assist with holding the toddler in a prone position. B. Place the toddler in a side-lying, knee-chest position. C. Restrain the toddler for 1 hr after the procedure. D. Swaddle the toddler in a warm blanket.

Correct Answer is B

Explanation

Choice A rationale

While assistance may be needed to comfort the toddler during the procedure, holding the toddler in a prone position is not the recommended position for a lumbar puncture.

Choice B rationale

Placing the toddler in a side-lying, knee-chest position is the correct position for a lumbar puncture. This position helps to open up the spaces between the vertebrae, making it easier to access the spinal canal.

Choice C rationale

Restraining the toddler for 1 hour after the procedure is not necessary and could cause distress to the toddler.

Choice D rationale

While swaddling the toddler in a warm blanket may provide comfort, it is not a necessary step in the administration of a lumbar puncture.
