The nurse is assessing the psychosocial development of a preschooler. What are normal activities characteristic of the preschooler? Select all that apply.

A. A 7-year-old child who has diabetes insipidus and a urine specific gravity of 1.016: While diabetes insipidus requires monitoring and management, a urine specific gravity of 1.016 alone does not indicate acute distress or an emergency situation. The child may need adjustments in fluid intake or medication, but this can typically be addressed in a less urgent manner.

B. A 10-year-old child who has sickle cell anemia who reports severe chest pain: Severe chest pain in a child with sickle cell anemia could indicate a vaso-occlusive crisis affecting the chest, which is potentially life-threatening. Prompt assessment and intervention are necessary to

manage the pain and prevent complications, including acute chest syndrome or respiratory compromise.

C. A 1-year-old toddler who has roseola and a temperature of 39°C (102.2°F): Roseola is typically a benign viral illness characterized by fever and a rash. While a fever in a young child

requires monitoring and symptomatic management, it is not usually considered an emergency unless accompanied by other concerning symptoms such as dehydration or respiratory distress.

D. A 4-year-old child who has asthma and a PCO2 of 37 mm: While asthma exacerbations can be serious, a PCO2 level of 37 mm indicates normal carbon dioxide levels, which do not suggest acute respiratory distress or impending respiratory failure. However, if the child is experiencing severe respiratory distress, cyanosis, or altered mental status, immediate assessment and

intervention would be warranted.

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.
