GROWTH & DEVELOPMENT (Questions 1-25)
Q1. A nurse is assessing a 6-month-old infant's developmental milestones. Which
finding is expected?
A) Walks with support
B) Rolls from back to front
C) Uses a pincer grasp
D) Says two-word phrases
Correct Answer: B
Rationale: At 6 months, infants typically roll over in both directions. Walking with

dysfunction or acute respiratory distress and requires immediate reporting .
