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.
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 B
Explanation
Choice A rationale
A set of blocks to build a block tower may not be suitable for a 7-month-old infant. At this age, infants are still developing their fine motor skills and may not have the dexterity to stack blocks effectively. Moreover, there’s a risk of the infant putting small blocks in their mouth, posing a choking hazard.
Choice B rationale
A soft toy that squeaks or crackles when squeezed is an excellent choice for a 7-month-old infant. At this age, infants are exploring their environment through touch and sound. A soft toy that makes noise when squeezed can provide sensory stimulation and help develop their grasp reflex.
Choice C rationale
A colorful rib mobile that plays music might be more suitable for younger infants. By 7 months, infants are often able to sit up and may not spend as much time lying down looking at a mobile. Additionally, they may try to pull on the mobile, posing a safety risk.
Choice D rationale
A wooden farm animal puzzle with large pieces is typically more appropriate for older toddlers who have more advanced fine motor skills and cognitive abilities. A 7-month-old infant may not have the ability to understand the concept of a puzzle.
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.
