Sample CPN Practice Questions

Try these sample questions to review concepts for the CPN exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 201+ question experience with AI tutoring.

1A caregiver asks which motor skill is typical by the 6-month well visit. Which example should the nurse give?

A.Sitting for brief periods with both hands for support

B.Walking with support while holding furniture

C.Using a pincer grasp to pick up small objects

D.Using several words to ask for objects

Explanation: By 6 months, most infants lean on their hands to steady themselves while sitting. Unsupported sitting is a 9-month milestone. Pulling to stand, cruising, and a thumb-and-finger grasp appear later.

2A mother asks the nurse when her 2-year-old toddler should be able to use two-word sentences. Which response by the nurse is most accurate?

A.By 12 months of age

B.By 24 months of age

C.By 30-36 months of age

D.By 4 years of age

Explanation: By age 2, most children combine at least two words, such as 'more milk.' A child who has not reached this milestone should receive developmental follow-up.

3A caregiver asks about 4-year milestones. The child names several colors, draws a person with three body parts, and usually catches a large ball. What should the nurse tell the caregiver?

A.Developmental delay requiring referral

B.Age-appropriate development

C.Advanced development for age

D.Need for further neurological assessment

Explanation: Drawing a person with at least three body parts, naming some colors, and catching a large ball most of the time are typical 4-year milestones.

4In Erikson's psychosocial model, which developmental task is associated with the preschool years?

A.Trust vs. Mistrust

B.Autonomy vs. Shame and Doubt

C.Initiative vs. Guilt

D.Industry vs. Inferiority

Explanation: In Erikson's model, initiative versus guilt is the preschool task. Trust is associated with infancy, autonomy with toddlerhood, and industry with the school years.

5The nurse is providing anticipatory guidance to parents of a 9-month-old infant. Which statement about sleep safety is most appropriate?

A.Place the infant on their stomach to sleep once they can roll over

B.Use soft bedding and pillows to keep the infant comfortable

C.Place the infant on their back on a firm, flat mattress without loose bedding

D.Share the adult bed until 12 months of age

Explanation: Place the infant on their back on a firm, flat, noninclined sleep surface and keep it free of loose bedding and soft objects. Room-sharing with a separate infant sleep surface is recommended.

6Parents of a 15-month-old ask the nurse about toilet training readiness. Which developmental sign indicates the child may be ready to begin toilet training?

A.The child can walk independently

B.Stays dry for two hours and shows potty interest

C.The child can speak in 3-word sentences

D.The child can dress and undress independently

Explanation: Readiness cues include staying dry for about two hours, showing interest, and following simple directions. The timing varies, so assess readiness and avoid pressure.

7The nurse is counseling parents about screen time for their 3-year-old child. According to current AAP guidelines, which recommendation is most appropriate?

A.Allow solo viewing of age-rated programs during meals

B.Use educational apps to replace some active play

C.Co-view quality content and protect sleep and play

D.Set viewing limits based only on the child's age

Explanation: AAP guidance emphasizes content quality, shared use, and boundaries that protect sleep, active play, and family time. A Family Media Plan can help caregivers choose content and set routines.

8A 4-year-old has outgrown rear-facing use and remains within the forward-facing harness limits of the car seat. Which restraint should the nurse recommend?

A.The child can use a seat belt without a booster seat

B.Use the forward-facing harness and tether

C.The child should use a belt-positioning booster seat

D.Use a booster in the front passenger seat

Explanation: Keep the child in a forward-facing seat with a harness and tether until the seat's forward-facing height or weight limit is reached. Then use a belt-positioning booster in the back seat. The seat's limits determine when to transition.

9The nurse is providing safety education to parents of a 10-month-old infant. Which statement indicates the parents understand appropriate injury prevention measures?

A."We tie the window blind cords at crib height."

B."We keep medications in a locked cabinet out of reach"

C."We allow our baby to sleep with a small blanket for comfort"

D."We installed a gate at the bottom of the stairs only."

Explanation: Lock medications out of sight and reach. Use a bare infant sleep space and install appropriate stair gates at both the top and bottom. Remove or secure blind cords where children cannot reach them.

10A mother asks the nurse when she can introduce solid foods to her breastfed infant. Which response by the nurse is most accurate?

A.At 3-4 months when the infant can hold their head up

B.At approximately 6 months when showing signs of readiness

C.At 9 months to ensure proper digestive system development

D.Solid foods should not be introduced until 12 months

Explanation: The AAP recommends exclusive breastfeeding for about 6 months, with introduction of complementary foods at approximately 6 months when the infant shows signs of readiness (sitting with support, good head control, interest in food, ability to move food to back of mouth).
