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 A
Explanation
A. "Tell me about the circumstances when this occurs.": This response allows the nurse to gather more information about the child's toileting habits and potential triggers for the accidents.
Understanding the context can help identify possible underlying causes and guide appropriate interventions.
B. "Is there a family history of diabetes?": While diabetes can be a cause of increased urination, asking about a family history of diabetes is premature and may unnecessarily alarm the parent before further assessment.
C. "Suddenly having accidents can be a sign of diabetes.": Jumping to conclusions about a serious medical condition like diabetes without further assessment or evidence can cause unnecessary anxiety for the parent. It's important to gather more information and consider other potential causes before suggesting a diagnosis.
D. "That's normal: don't worry about it.": While occasional daytime wetting accidents can be common in young children, dismissing the concern without further assessment may overlook potential underlying issues that could benefit from intervention or support.
Correct Answer is B
Explanation
A. Pulse rate is increased.
While there may be variations in pulse rate due to factors such as activity level and emotional state, a significant increase in pulse rate would not be a typical finding during an annual check- up for an 8-year-old child.
B. Breathing is diaphragmatic.
As children grow older, their respiratory patterns mature, and they develop diaphragmatic breathing, which is deeper and more efficient than the shallow breathing observed in infants. This change would be expected as the child gets older.
C. Secondary sex characteristics are present.
The development of secondary sex characteristics typically occurs during puberty, which begins around the ages of 9 to 13 in girls and 10 to 14 in boys. At 8 years old, it would be unlikely for significant secondary sex characteristics to be present.
D. Blood pressure has reached adult level.
Blood pressure in children gradually increases with age, but it does not reach adult levels until adolescence. At 8 years old, the child's blood pressure would still be within the pediatric range and would not resemble adult levels.
