Sample questions from ATI Lon 2026 Pediatric Proctored

This material has 90 questions with answers and rationales. Here are the first 5.

1. 1.Which behavior is most expected of a 2-year-old child?

   • A.Uses parallel play beside another child
   • B.Plays cooperatively with a group of children
   • C.Understands abstract explanations
   • D.Has mastered conservation of volume

   Rationale: Toddlers commonly engage in parallel play, playing beside rather than cooperatively with peers. Cooperative play develops later, and abstract reasoning and conservation are beyond typical toddler development. Match expectations to the child's developmental stage rather than chronological age alone.

2. 2.During a well-child visit, a parent asks when to begin toilet training. Which response is best?

   • A.Start training only after the child turns 3 years old
   • B.Wait until the child shows readiness cues, such as staying dry and communicating the need
   • C.Begin when the child can walk independently
   • D.Begin at 12 months to establish a routine early

   Rationale: Toilet training is most successful when the child shows readiness, including awareness of elimination, ability to communicate, and periods of dryness. Walking alone does not establish readiness, and a fixed age is not appropriate for every child. Pressuring an unready child can increase resistance.

3. 3.The parent of a 9-month-old asks which home activities support safe development. Select all that apply.

   • A.Place small objects out of reach
   • B.Leave the infant briefly in a bathtub while retrieving a towel
   • C.Use a rear-facing car seat in the back seat
   • D.Offer supervised floor play in a childproofed area
   • E.Place the infant on the stomach for every sleep

   Rationale: Keeping small objects away reduces choking risk, and supervised floor play supports motor development in a safe environment. A rear-facing seat in the back seat is appropriate for an infant. Leaving an infant unattended near water is unsafe, and infants should be placed supine for sleep, not prone.

4. 4.A preschooler says, "I got sick because I was bad." Which response by the nurse is most appropriate?

   • A."Try not to think about the illness."
   • B."Being sick is a consequence of not following rules."
   • C."You did not cause your illness by misbehaving."
   • D."You should ask your parents why you became sick."

5. 5.Which assessment finding is most useful for evaluating growth in a child over time?

   • A.A single height measurement compared with an adult reference value
   • B.The child's shoe size compared with classmates
   • C.A parent's estimate of the child's recent growth
   • D.Serial height and weight plotted on an age- and sex-appropriate growth chart
