The nurse performing a health history on a child asks the parents if their child has experienced increased appetite or thirst. What body system is the nurse assessing with this question?

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. Areola and papilla separate from the contour of the breast: This is a normal finding in breast development and indicates Tanner stage 4 or higher, which is typical for adolescent girls. It does not necessarily indicate a developmental delay.

B. Absence of first menstrual perioD. Menarche, the first menstrual period, typically occurs between the ages of 9 and 15 in girls. Absence of menarche by the age of 15 or within 3 years after the onset of breast development (thelarche) may indicate a developmental delay or underlying medical condition that should be evaluated by a healthcare provider.

C. Developed breast tissuE. Breast development, indicated by palpable breast tissue, is a normal part of female puberty and typically occurs before menarche. Developed breast tissue alone does not necessarily indicate a developmental delay.

D. Mature distribution and coarseness of pubic hair: Pubic hair development is also a part of female puberty and occurs before or around the time of menarche. While the distribution and coarseness of pubic hair can provide information about pubertal development, the absence of menarche is a more reliable indicator of a potential developmental delay.
