A nurse is collecting data from a 6-month-old infant in the well child clinic.
Which of the following findings should the nurse expect?

A.

Infant's birth weight is tripled.

B.

Lateral incisors are present.

C.

Posterior fontanel is closed.

D.

Infant sits well without support.

Answer and Explanation

The Correct Answer is C

Choice A rationale

The infant's birth weight typically doubles by 4-6 months and triples by 1 year of age. If an infant's weight has tripled at 6 months, it may indicate overnutrition or an underlying health condition.

 

Choice B rationale

Lateral incisors usually appear between 9 to 13 months. At 6 months, the central incisors are more likely to be emerging.

 

Choice C rationale

The posterior fontanel typically closes by 2 to 3 months of age. Therefore, by 6 months, it is expected to be closed.

 

Choice D rationale

Infants usually sit without support around 8 months. At 6 months, they may sit with support or briefly without support but not consistently.

Correct Answer is D

Explanation

Choice A rationale

A brightly-colored mobile is suitable for infants who are visually stimulated by motion and color but not appropriate for a 4-year-old.

Choice B rationale

A checkerboard and checkers are more suitable for older children or adolescents who have developed advanced cognitive and strategic thinking skills.

Choice C rationale

A 100-piece jigsaw puzzle is also more appropriate for older children or adolescents with well-developed problem-solving and fine motor skills.

Choice D rationale

Hand puppets are suitable for a 4-year-old as they encourage imaginative play, storytelling, and fine motor skill development.

Correct Answer is C

Explanation

Choice A rationale

Allowing an additional 30 minutes of play before bedtime can lead to overstimulation and delay the child's ability to settle down for sleep. Consistent bedtime routines are crucial for

establishing healthy sleep patterns in children.

Choice B rationale

Letting the child sleep in the parent's bed can create dependency and difficulty in establishing the child's own sleep routine and space. This practice can disrupt both the parent's and

child's sleep in the long term.

Choice C rationale

Keeping a night light on provides a sense of security and comfort for a child who may be afraid of the dark. This helps the child feel safe and can ease the transition to bedtime.

Choice D rationale

Staying with the child until they fall asleep, especially if crying, can reinforce the behavior and make it harder for the child to develop self-soothing skills. It can lead to increased

dependency on the parent's presence to fall asleep.
