The nurse teaching safety to teens knows that which of these is the leading cause of death among adolescents?

A. Most infants double their birth weight by 5 to 6 months of age.

B. Doubling of birth weight by 3 months is less common and may indicate overfeeding or an error in measurement.

C. By 9 months, infants have usually surpassed the milestone of doubling their birth weight.

D. At 12 months, infants typically triple their birth weight, so this is beyond the timeframe for doubling birth weight

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.
