## Question

At a 4-year-old well-child visit, the nurse notes the child's immunization record shows vaccines given only through the 18-month visit. The parent reports the child recently stopped playing pretend games and no longer draws a person with several body parts, skills he demonstrated last year, though he can catch a large ball. The child currently rides in a forward-facing car seat with a harness and can sit independently without support. Which nursing actions are appropriate at this visit? Select all that apply.

1

Notify the provider that catch-up vaccinations are due based on the gap since the child's 18-month visit.

2

Refer the child for developmental follow-up because he has stopped engaging in pretend play and no longer draws a person with several body parts, skills he previously demonstrated.

3

Document that the child's fine-motor skills are age-appropriate because he can stack four blocks into a tower.

4

Tell the parent that additional vaccines are not needed right now since the child has not shown any illness symptoms since the last visit.

5

Advise the parent that the child can transition out of a forward-facing car seat with a harness now that he can sit independently and unsupported in a regular seat.

6

Reinforce that the child should remain in the forward-facing harness until reaching the seat's height or weight limit, then use a belt-positioning booster.

## Explanation

At the 4-year well-child visit, the documented immunization gap requires catch-up planning (Choice 1), and loss of previously mastered pretend play and drawing skills requires prompt developmental follow-up (Choice 2). The child should remain in the forward-facing harness until its height or weight limit is reached and then use a belt-positioning booster (Choice 6). Stacking four blocks is an earlier milestone and does not establish age-appropriate fine-motor development (Choice 3). Lack of recent illness does not remove the need for catch-up immunization (Choice 4), and sitting independently is not the criterion for leaving a harnessed seat (Choice 5).

## In-depth explanation

Correct Answer
Choices 1, 2, 6

Clinical Reasoning
At the 4-year well-child visit, the documented immunization gap requires catch-up planning (Choice 1), and loss of previously mastered pretend play and drawing skills requires prompt developmental follow-up (Choice 2). The child should remain in the forward-facing harness until its height or weight limit is reached and then use a belt-positioning booster (Choice 6). Stacking four blocks is an earlier milestone and does not establish age-appropriate fine-motor development (Choice 3). Lack of recent illness does not remove the need for catch-up immunization (Choice 4), and sitting independently is not the criterion for leaving a harnessed seat (Choice 5).

Option Review

- Correct — The vaccination record shows no immunizations since 18 months, so the nurse should notify the provider so catch-up vaccines appropriate for a 4-year-old can be ordered without delay.

- Correct — Loss of previously mastered skills such as pretend play and drawing a person with several parts is a red flag for regression and warrants referral for developmental evaluation now rather than watchful waiting.

- Incorrect — Stacking four blocks reflects an earlier fine-motor milestone typically achieved well before age four, so this finding does not confirm that the child's current fine-motor skills are age-appropriate.

- Incorrect — Absence of illness symptoms does not eliminate the need for catch-up immunizations; the documented gap since the 18-month visit still requires the provider to order missed vaccines.

- Incorrect — Sitting independently and unsupported is not the criterion for discontinuing a harnessed car seat; that decision depends on the child's height and weight meeting the seat's forward-facing limits.

- Correct — A 4-year-old should remain in a forward-facing harness until the child reaches that seat's height or weight limit, then transition to a belt-positioning booster until the vehicle belt fits properly.

## Clinical scenario

A 4-year-old is brought for a well-child visit; immunizations are documented only through the 18-month visit, and the parent describes loss of previously acquired play and drawing skills alongside continued gross-motor ability and independent sitting in a forward-facing harnessed car seat.
