A nurse is collecting data from a 9-month-old infant. Which of the following developmental findings should the nurse expect?
Crude pincer grasp
Shakes head for "no"
Uses two-word phrases
Builds a four-block tower
The Correct Answer is A
A. A 9-month-old infant is expected to demonstrate a crude pincer grasp, which involves picking up small objects between the thumb and forefinger. This is a developmental milestone for this age.
B. While infants may shake their heads by this age, it is typically not used in the context of saying "no." This action is usually a sign of exploration or reaction to stimulation.
C. A 9-month-old typically does not use two-word phrases. By this age, infants are usually babbling and may say single words like "mama" or "dada."
D. A 9-month-old is not expected to build a tower of four blocks. By 12-15 months, infants may begin to stack blocks.
