Difficulty: MediumDevelopmental Stages and Transitions

A practical nurse is collecting data during a routine wellness visit for a 5-month-old infant. The parents ask about the physical skills their baby should be developing at this time. Which finding should the nurse identify as an expected developmental milestone for this infant?

  1. Rolling over from the abdomen to the backAnswer
  2. B
    Sitting completely unsupported for several minutes
  3. C
    Using a pincer grasp to pick up small items
  4. D
    Pulling up to a standing position in the crib

Answer

The expected developmental milestone for a 5-month-old is rolling over from the abdomen to the back.
At 5 months of age, an infant is typically expected to have mastered rolling from their abdomen (prone) to their back (supine). This normal gross motor milestone generally develops between 4 and 5 months of age as the infant gains sufficient head control and core strength.

Step-by-Step Solution

1
Identify the client's age and the specific domain of development being assessed.
The client is a 5-month-old infant, and the question asks for an expected physical developmental milestone.
Developmental milestones are age-specific, making the infant's exact chronological age the critical factor in selecting the correct answer.
2
Recall the standard gross and fine motor milestones for a 5-month-old infant.
By 4 to 5 months, an infant typically gains the core strength to roll from their abdomen to their back.
Recalling normal physiological development is necessary to differentiate expected findings from those that occur later in infancy.
3
Evaluate the distractors against the 5-month timeline.
Sitting unsupported (8 months), using a pincer grasp (9-10 months), and pulling to a stand (9 months) are all milestones that occur in the second half of the infant's first year.
Ruling out milestones that are too advanced confirms the correct choice.
