A nurse provides care to a 6-month-old infant.Which observation should be reported to the pediatrician?
Grasps objects voluntarily.
Posterior fontanel is closed.
Birth weight has doubled.
Demonstrates head lag (lack of head control).
The Correct Answer is D
Choice A rationale
A 6-month-old infant typically grasps objects voluntarily, which is a normal developmental milestone.
Choice B rationale
The posterior fontanel usually closes between 2 to 3 months of age, so it being closed at 6 months is normal.
Choice C rationale
It's expected for an infant's birth weight to double by about 5 to 6 months of age, indicating healthy growth.
Choice D rationale
Head lag in a 6-month-old indicates a delay in motor development and should be reported as it can signal neurological issues.

Correct Answer is C
Explanation
Choice A rationale
Placing the infant safety seat in the middle of the back seat away from the windows is the safest position, protecting the child from potential impact during accidents and from direct sunlight or objects coming through windows.
Choice B rationale
Following the child's weight and height is crucial for safely transitioning from an infant car seat to a booster seat. This ensures proper restraint and protection as the child grows.
Choice C rationale
Allowing a baby to watch the driver while in the back seat indicates a forward-facing position, which is unsafe for infants. Rear-facing positions provide the best protection for an infant's head, neck, and spine.
Choice D rationale
Using a previously owned car seat with intact instructions can ensure proper installation and use. However, checking the seat's history and condition is crucial to ensure it meets current safety standards.
Correct Answer is D
Explanation
Choice A rationale
Introducing well-cooked table foods should begin around 8-10 months of age when the baby is ready for finger foods and has developed better chewing skills.
Choice B rationale
Starting solid foods at 3 months old is too early and can interfere with breastfeeding or formula feeding, increasing the risk of allergies and digestive issues.
Choice C rationale
Cow's milk should not be introduced until 12 months of age, as infants need the nutrients from breast milk or formula during their first year for optimal growth.
Choice D rationale
It is recommended to wait until the baby is at least 6 months old before introducing fruit juice, and even then, it should be given in limited quantities to avoid excessive sugar intake.
