When her preschool son is in the hospital, the parent tells the nurse, “I think there is something wrong with him because he is so skinny.” The most appropriate answer by the nurse is:

Preschoolers (ages 3–5) are in Piaget’s preoperational stage, where they exhibit egocentrism, magical thinking, and limited logical reasoning. Understanding these concepts helps nurses and caregivers approach communication and education effectively.

Rationale for correct answers:

1. Egocentric thought is a hallmark of preschoolers. They often assume others see, think, and feel exactly as they do. This is a normal part of early cognitive development and limits their ability to adopt other perspectives.

2. Play as a tool is powerful in this age group. Through imaginative play and role-playing, preschoolers express feelings and demonstrate what they comprehend about the world around them. Nurses often use therapeutic play to reduce anxiety or assess a child's perception of illness or hospitalization.

5. Magical thinking is common in preschoolers. They may believe their thoughts or wishes cause real events. This can lead to feelings of guilt if something bad happens, as they might believe they caused it. Nurses must provide reassurance and clarification.

Rationale for incorrect answers:

3. Explanations with detail may be overwhelming. Preschoolers benefit from simple, concrete explanations. Using too much detail or abstract reasoning may increase confusion and stress rather than reduce it.

4. Understanding inferences and empathy is limited in this stage. While preschoolers may show basic concern if someone is sad, they do not yet fully grasp abstract feelings or make emotional inferences as older children or adults can. Their empathy is emerging but not mature.

Take home points

• Preschoolers are egocentric and view the world from their own perspective.
• Magical thinking can lead to misunderstandings about illness, death, or punishment.
• Play is not just recreational, it’s a window into their cognitive and emotional world.
• Explanations should be concrete, visual, and brief, avoiding abstract reasoning.

Visual acuity refers to the clarity or sharpness of vision. Visual acuity improves with age, reaching 20/20 by approximately age 6–7. Early detection of vision problems is important to prevent conditions like amblyopia, which can be treated more effectively when caught early.

Rationale for correct answer:
3. At age 4, 20/40 vision is developmentally normal. This means the child can see at 20 feet what a person with perfect vision sees at 40 feet. It reflects typical visual development at this age.

Rationale for incorrect answers:

1. 10/10 is not a standard measurement in vision testing and is not used clinically in the U.S.

2. 20/20 vision is ideal but not expected for most 4-year-olds. While some may achieve it, it is more typical for older children, around 6 years and above.

4. 40/40 is not a valid or recognized measure of visual acuity. Standard measurements use 20 as the baseline.

Take home points

• 20/40 is normal visual acuity for a 4-year-old, with gradual improvement expected as the child grows.
• Routine vision screening begins in the preschool years to identify early issues.
• Nurses should recognize age-based norms to properly evaluate developmental progress and guide parental expectations.
• Referral is needed if visual acuity is worse than age norms or if there's evidence of strabismus or other visual concerns.
