A child is hospitalized after a serious motor vehicle crash and has developed increased urination. What action by the nurse takes priority?

The assessment finding that the nurse should expect in an infant with Hirschsprung disease is option A, constipation with the passage of foul-smelling, ribbon-like stools. Hirschsprung disease is a congenital condition characterized by the absence of ganglion cells in the distal part of the colon, leading to functional obstruction. The affected segment of the colon lacks the normal peristaltic movements, resulting in an accumulation of faecal matter. The stools passed by infants with Hirschsprung disease are often constipated, and the narrow, ribbon- like appearance is a result of the narrowed segment of the colon.

diarrhea (option B) is incorrect because it, is not typically associated with Hirschsprung disease. Instead, the condition presents with constipation due to the obstructed bowel.

foul-smelling, fatty stools in (option C) is incorrect because it, is not characteristic of Hirschsprung disease. This finding may be associated with malabsorption disorders such as cystic fibrosis or celiac disease, but not specifically with Hirschsprung disease.

"currant jelly" stools in (option D) is incorrect because it, is a term commonly used to describe the stools seen in intussusception, which is a different condition involving the telescoping of one segment of the bowel into another. It is not an expected finding in Hirschsprung disease.

Precocious puberty is defined as the onset of puberty before the age of 8 in girls and before the age of 9 in boys. However, it is important to note that the exact age at which puberty is considered precocious can vary slightly based on different guidelines and individual variations.

Boys: 11 years; girls: 9 years in (option A) is incorrect because it, is close to the general age range, but it is slightly earlier than what is commonly considered precocious puberty.

Boys: 10 years; girls: 9 1/2 years in (option C) is incorrect because it, is also close to the general age range, but it is not as commonly recognized as the age for precocious puberty.

Boys: 9 years; girls: 8 years in (option D) is incorrect because it, is significantly earlier than the usual age for precocious puberty. Puberty occurring at this age would be considered very early and may warrant further evaluation.
