The mother of a 4-year-old boy tells the nurse that her son occasionally wets his pants during the day. How should the nurse respond?

A. The child does not vocally respond to voices: While vocal responsiveness is an important aspect of development, it may vary among infants and is not necessarily indicative of a developmental problem at 4 months.

B. The child never squeals or yells: Squealing and yelling are vocalizations that infants may or may not exhibit at this age, and their absence alone may not necessarily indicate a developmental problem.

C. The child does not babblE. Babbling, which typically begins around 4 to 6 months of age, involves the repetition of consonant-vowel combinations (e.g., "bababa"). The absence of babbling by 4 months may suggest a delay in language development and could be a potential sign of a developmental problem.

D. The child does not say dada or mamA. Infants may begin to associate "dada" or "mama" with specific caregivers, but this typically occurs later, closer to 6 to 9 months of age. The absence of this behavior at 4 months may not necessarily indicate a developmental problem.

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.
