A nurse is caring for a child who has Hirschsprung disease. Which of the following findings should the nurse expect?
Ridged abdomen
Ribbonlike, foul-smelling stools
Projectile vomiting
Chronic hunger
The Correct Answer is B
A. Ridged abdomen - This finding is not typically associated with Hirschsprung disease. Instead, the abdomen may appear distended or bloated due to the accumulation of stool in the colon.
B. Ribbonlike, foul-smelling stools - This is a characteristic finding in Hirschsprung disease. Because the affected portion of the colon lacks nerve cells (ganglion cells) responsible for peristalsis, stool movement is impaired, leading to the passage of narrow, ribbonlike stools. These stools may also have a foul odor due to bacterial overgrowth in the affected area.
C. Projectile vomiting - Projectile vomiting is not a common finding in Hirschsprung disease. It is more commonly associated with conditions such as pyloric stenosis or gastroesophageal reflux.
D. Chronic hunger - Chronic hunger is not a typical finding in Hirschsprung disease. Instead, affected infants may experience feeding difficulties, constipation, and failure to thrive due to the obstruction of stool in the colon. They may also exhibit symptoms such as abdominal distention, vomiting, and refusal to feed.

Correct Answer is C
Explanation
A. "Lice do not survive away from the host."
- This statement is incorrect. Lice can survive away from the host (human scalp) for a limited period, usually up to 1-2 days. They may be found on items such as bedding, clothing, hats, or hair accessories. Therefore, proper cleaning and disinfection of these items are essential to prevent the spread of lice.
B. "Washing your child's hair daily will prevent lice."
- This statement is incorrect. While maintaining good hygiene is important, washing hair daily does not necessarily prevent lice infestation. Lice infestations occur through direct head-to-head contact with an infested person, not due to uncleanliness. Additionally, lice are more commonly found in clean hair rather than dirty hair.
C. "Encourage your child to avoid sharing hats with other children."
- This statement is correct. Sharing personal items such as hats, scarves, brushes, or hair accessories can facilitate the spread of lice from one person to another. Therefore, it's important to advise children not to share these items to reduce the risk of lice transmission.
D. "Lice can jump from one child to another."
- This statement is incorrect. Lice do not have the ability to jump or fly. They spread through direct contact with the hair or scalp of an infested person. However, they can crawl quickly from one person to another, especially when there is close contact, such as during play or when sharing personal items.
Correct Answer is D
Explanation
A. Abdominal wall defect:
Failure to pass meconium within the first 24 hours after birth can indicate a potential obstruction in the gastrointestinal tract. While an abdominal wall defect could potentially cause gastrointestinal issues, it is not specifically associated with failure to pass meconium.
B. Celiac disease:
Celiac disease is an autoimmune disorder characterized by an abnormal immune response to gluten. While celiac disease can cause gastrointestinal symptoms, such as diarrhea and abdominal pain, it is not typically associated with failure to pass meconium in the newborn period.
C. Intussusception:
Intussusception occurs when one segment of the intestine telescopes into another, causing a bowel obstruction. While intussusception is a cause of bowel obstruction in infants, it typically presents with symptoms such as colicky abdominal pain, vomiting, and the passage of "currant jelly" stool, rather than failure to pass meconium.
D. Hirschsprung disease:
Hirschsprung disease is a congenital condition characterized by the absence of ganglion cells in the distal portion of the colon, leading to functional obstruction. Failure to pass meconium within the first 24 hours after birth is a classic sign of Hirschsprung disease. This condition requires surgical intervention to remove the affected portion of the colon and restore normal bowel function.
