The nurse is teaching a new mother about the drastic growth and developmental changes her infant will experience in the first year of life. Which statement describes a developmentalmilestone occurring in infancy?
The heart triples in size over the first year of lifE. the average pulse rate decreases from 120 to 140 in the newborn to about 100 in the 1-year-old.
Most infants triple their birth weight by 4 to 6 months of age and quadruple their birth weight by the time they are 1 year old.
By 6 months of age, the infant's brain weighs half that of the adult brain; at age 12 months, the brain weighs 2.5 times what it did at birth.
The head circumference increases rapidly during the first 6 months: the average increase is about 1 in per month.
The Correct Answer is B
A. The heart triples in size over the first year of lifE. While cardiac growth occurs during infancy, the described change is not specific to a developmental milestone.
B. Most infants triple their birth weight by 4 to 6 months of age and quadruple their birth weight by the time they are 1 year olD. This statement accurately describes a significant developmental milestone related to physical growth during infancy.
C. By 6 months of age, the infant's brain weighs half that of the adult brain; at age 12 months, the brain weighs 2.5 times what it did at birth: This statement describes brain growth rather than a
milestone related to physical growth or development.
D. The head circumference increases rapidly during the first 6 months: the average increase is about 1 in per month: While head circumference growth is important, it does not specifically relate to the described developmental milestone of weight gain during infancy.

Correct Answer is C
Explanation
A. Place the crushed tablet in the infant's formulA. Mixing crushed tablets with formula may alter the taste or consistency of the formula, making it less palatable for the infant.
B. Mix the crushed tablet with the infant's cereal: Mixing crushed tablets with cereal may also alter the taste and texture of the cereal, potentially making it unappealing to the infant.
C. Mix the crushed tablet with a small amount of applesaucE. Mixing crushed tablets with a small amount of applesauce is a common method for administering medication to infants and
toddlers. The applesauce helps mask the taste and texture of the crushed tablet, making it easier for the child to swallow.
D. Crushed tablets should only be mixed with water: While water can be used to administer crushed tablets, mixing them with water alone may not effectively mask the taste or texture of the medication, making it less likely that the child will swallow it. Mixing with a food like applesauce is often more palatable for young children.

A. Displays of animism: Animism, attributing life-like qualities to inanimate objects, is a typical characteristic of the preoperational stage as children develop symbolic thinking.
B. Understanding of opposites: The ability to understand opposites, such as big/small, hot/cold, is a cognitive milestone of the preoperational stage as children develop classification skills.
C. Use of active imaginations: Pretend play and active imaginations are hallmark features of the preoperational stage, reflecting children's growing ability to engage in symbolic thought and fantasy play.
D. Beginning questioning of parents' values: Piaget's preoperational stage, which typically occurs between ages 2 and 7, is characterized by significant cognitive development, including language acquisition, symbolic thinking, and the ability to engage in pretend play. While children in this stage may question certain aspects of their environment and beliefs, they are less likely to engage in sophisticated questioning of abstract concepts like parental values.
