Which of the following findings should the nurse identify as a potential developmental delay?

The correct answer is B: Walks with assistance. Walking independently is a milestone typically achieved around 12-15 months. Walking with assistance beyond this age may indicate a developmental delay in gross motor skills. Engaging in parallel play (A) is typical for toddlers. Speaking at least 10 words (C) is a language development milestone. Building a tower of 3 blocks (D) is a fine motor skill milestone. The absence of other choices indicates they are not relevant to developmental delays.
