A nurse is assessing a 3 year-old-child at a routine wellness checkup. Which of the following findings should the nurse expect?

A. A vocabulary of 1,500 words is more characteristic of a 5-year-old; by age 3, a child usually has a vocabulary of about 200 to 1,000 words. B. Skipping and hopping on one foot typically develops around ages 4 to 5, so it would not be expected of a 3-year-old. C. Walking backwards heel to toe is a skill that develops later, generally around age 4 or 5, rather than being typical at age 3. D. A 3-year-old typically can stand on one foot for a few seconds, demonstrating developing balance and coordination skills that are characteristic of this age group.
