A nurse in a clinic is assessing a 7-month-old infant. Which of the following indicates a need for further evaluation?

The correct answer is A: Uses a pincer grasp. At 7 months, infants typically develop a pincer grasp around 9-10 months. This indicates fine motor skills development. If a 7-month-old is already using a pincer grasp, it may suggest advanced development, requiring further evaluation. Choices B, C, and D are typical developmental milestones for a 7-month-old and do not raise immediate concerns. B: Fear of strangers is a common developmental stage. C: Showing food preferences is a normal part of exploring tastes. D: Babbling one-syllable sounds is typical for language development at this age.
