A nurse is assessing a 16-month-old toddler. Which of the following findings should the nurse report to the provider?

A. At 16 months, toddlers are not expected to speak in full sentences. They typically use one- to two-word phrases. B. Jumping with both feet is a skill usually seen closer to age 2-3 years, so it is not a concern for a 16-month-old. C. Inability to stand upright without support at 16 months is a developmental delay and should be reported to the provider for further evaluation. D. Building a tower of six to seven cubes is a skill expected closer to 2 years of age, so it is not a concern at 16 months.
