When a 2-week-old infant is seen for irritability, poor appetite, and rapid head growth with observable distended scalp veins, the nurse recognizes these signs as indicative of which disorder?
Cerebral palsy
Syndrome of inappropriate antidiuretic hormone (SIADH)
Hydrocephalus
Reye's syndrome
The Correct Answer is C
Hydrocephalus refers to a condition characterized by an abnormal accumulation of cerebrospinal fluid (CSF) within the ventricles of the brain. In infants, hydrocephalus can cause the head to enlarge rapidly as a result of the increased pressure exerted by the accumulating fluid. This is known as "rapid head growth." The increased intracranial pressure canlead to irritability and poor appetite in infants.
The distended scalp veins are another common sign of hydrocephalus. As the fluid accumulates, it puts pressure on theblood vessels in the brain, causing the veins in the scalp to become more visible and distended.
Cerebral palsy in (option A) is incorrect because is a neurological disorder that affects body movement and musclecoordination, but it does not typically present with rapid head growth or distended scalp veins.
Syndrome of inappropriate antidiuretic hormone (SIADH) in (option B) is incorrect because it is a condition characterized by excessive secretion of antidiuretic hormone, leading to fluid imbalance, but it does not usually cause rapid head growth or distended scalp veins. Reye's syndrome (D) is a rare condition that primarily affects the liver and brain, and it does not typically present with rapid head growth or distended scalp veins.
Therefore, based on the signs described, hydrocephalus (C) is the most likely disorder in this case. It is important to seekmedical attention promptly for a proper diagnosis and appropriate management of hydrocephalus in infants.

Correct Answer is A
Explanation
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.
Correct Answer is B
Explanation
The statement that best describes why infants are at greater risk for dehydration than older children is option B. Infants have an increased extracellular fluid volume compared to older children. This means that a larger proportion of their total body fluid is located outside the cells, in the extracellular compartment. This higher extracellular fluid volume makes infants more susceptible to fluid losses and dehydration if they experience inadequate fluid intake or increased fluid losses.
infants have an increased ability to concentrate urine in (option A), is incorrect. Infants have limited renal function and may have difficulty concentrating urine compared to older children and adults. This can contribute to a higher risk of dehydration in infants.
infants have a greater volume of intracellular fluid in (option C), is incorrect. The volume of intracellular fluid is not the primary factor contributing to the increased risk of dehydration in infants.
infants have a smaller body surface area in (option D) is incorrect because it, is not directly related to the increased risk of dehydration. Body surface area influences heat exchange and fluid loss through sweating but is not the main factor contributing to the higher risk of dehydration in infants.
