A nurse is collecting data from an 18-month-old toddler at a well-child visit. Which of the following findings should the nurse report to the provider?

c. The toddler can say four words. Explanation: The nurse should report to the provider that the toddler can say four words. At 18 months, a toddler typically has a vocabulary of about 6 to 20 words and is beginning to combine words into simple phrases. If the toddler is only able to say four words or has a delay in language development, it could be a cause for concern and warrant further evaluation. The other options are age-appropriate developmental milestones for an 18-month-old toddler and do not require immediate reporting to the provider. The ability to remove socks, having a security blanket, and throwing a ball without falling are all examples of normal developmental skills for a toddler of this age.
