milestone should the nurse expect the infant to
achieve?
A) Walks with assistance
B) Uses a pincer grasp
C) Sits without support
D) Says two-word phrases
Rationale: By 6 months, infants typically can sit
without support. Walking with assistance occurs
around 9–12 months, a pincer grasp develops around
9–10 months, and two-word phrases emerge around
2 years.
,2. A nurse is checking the gross motor
development of a 3-year-old child. Which of the
following skills should the nurse expect the child
to be able to do?
A) Skipping around the room
B) Hopping on one foot

finding should the nurse report to the provider?

,C) The infant is unable to walk independently
D) The infant needs assistance to sit up
Rationale: By 10 months, infants should be able to

disappear by 4–6 months, so its absence is expected.
Walking independently is not expected until 12–15
months.

development is a 5-year-old child in?
A) Sensorimotor
B) Preoperational
