A nurse is collecting data from a 6-month-old infant in the well child clinic.
Which of the following findings should the nurse expect?
Infant's birth weight is tripled.
Lateral incisors are present.
Posterior fontanel is closed.
Infant sits well without support.
The Correct Answer is C
Choice A rationale
The infant's birth weight typically doubles by 4-6 months and triples by 1 year of age. If an infant's weight has tripled at 6 months, it may indicate overnutrition or an underlying health condition.
Choice B rationale
Lateral incisors usually appear between 9 to 13 months. At 6 months, the central incisors are more likely to be emerging.
Choice C rationale
The posterior fontanel typically closes by 2 to 3 months of age. Therefore, by 6 months, it is expected to be closed.
Choice D rationale
Infants usually sit without support around 8 months. At 6 months, they may sit with support or briefly without support but not consistently.

Correct Answer is B
Explanation
Choice A rationale
Infants typically do not double their birth weight by 2-3 months. This milestone is more commonly reached slightly later in infancy.
Choice B rationale
By 5-6 months, many infants double their birth weight, indicating healthy growth and development. This timeline aligns with common pediatric growth patterns.
Choice C rationale
While growth continues at a steady pace, most infants have already doubled their birth weight before reaching 9 months. This age generally marks further physical and
developmental milestones.
Choice D rationale
By 12 months, infants have typically more than doubled their birth weight. This age is associated with continued growth, development, and new milestones.
Correct Answer is C
Explanation
Choice A rationale
Watermelon with seeds poses a choking hazard for young children, making it an unsafe food choice. The seeds can easily get stuck in a child’s throat, leading to potential airway obstruction. Additionally, small children might not have the coordination to properly spit out seeds, increasing the risk of accidental swallowing and subsequent choking. Therefore, whole fruits with seeds are generally recommended to be avoided for toddlers.
Choice B rationale
Raw carrots are another choking hazard for young children due to their hard texture. Toddlers might not have developed the necessary chewing skills to safely eat raw vegetables, increasing the risk of choking. Small, hard foods like raw carrots can be difficult to chew and swallow, making them unsafe for children under the age of three. Cooked or finely chopped vegetables are safer alternatives.
Choice C rationale
Mashed potatoes are a safe and appropriate food choice for a 14-month-old child. They are soft, easy to chew, and swallow, reducing the risk of choking. Mashed potatoes can be easily modified to suit the nutritional needs and texture preferences of young children. They can also be fortified with other healthy ingredients like pureed vegetables or proteins to make a balanced meal for toddlers.
Choice D rationale
Popcorn is a known choking hazard for young children and is not recommended for those under the age of four. Popcorn kernels are small, hard, and irregularly shaped, making them difficult for young children to chew and swallow safely. The risk of choking on popcorn is high due to its propensity to lodge in the airway, causing potentially serious complications. .
