A nurse is assessing a 4-month-old infant on a pediatric unit.
Which of the following findings should the nurse expect?
Uses thumb and index fingers in a pincer grasp.
Closed posterior fontanel.
Lateral incisors.
Sitting steadily without support.
The Correct Answer is B
Choice A rationale
A pincer grasp, using the thumb and index finger to pick up small objects, typically develops around 9 to 12 months of age, not at 4 months.
Choice B rationale
The posterior fontanel typically closes by the age of 2 to 3 months, so a 4-month-old infant would be expected to have a closed posterior fontanel. This finding is consistent with normal development.
Choice C rationale
Lateral incisors, the teeth on either side of the front teeth, typically erupt around 9 to 13 months of age, not at 4 months.
Choice D rationale
Sitting steadily without support generally occurs closer to 6 to 8 months of age, so it would not be expected in a 4-month-old infant.

Correct Answer is C
Explanation
Choice A rationale
AAP guidelines recommend rear-facing car seats for children under 24 months due to superior protection in a collision.
Choice B rationale
The chest buckle should be at armpit level to prevent injury in case of a crash.
Choice C rationale
Switching to a forward-facing car seat at 12 months contradicts safety recommendations; the child should remain rear-facing until at least 2 years old.
Choice D rationale
Car seats should always be placed in the back seat to minimize risk from front airbags during collisions.
Correct Answer is A
Explanation
Choice A rationale
This choice offers the toddler control and options within boundaries. By allowing the child to choose between two cups, it reduces the power struggle inherent in negativism, where the child often says "no" to assert independence.
Choice B rationale
This choice presents a direct option of now or later, which may still lead to refusal due to the toddler's negativism. Toddlers often respond better to choices that are less direct.
Choice C rationale
Asking if the child can take the medicine is likely to result in a "no" due to the nature of negativism at this developmental stage. It does not give the toddler a sense of control or choice.
Choice D rationale
Asking the child to be "good" places a moral judgment on taking the medicine, which is not developmentally appropriate and may lead to resistance.
