A child is diagnosed with sickle cell disease. The parents are unsure how their child contracted the disease. Which explanation by the nurse is the most appropriate?
"The father has the trait, but the mother doesn’t."
"The mother has the trait, but the father doesn’t."
"Both the mother and the father have the sickle cell trait."
"The mother has sickle cell disease, but the father doesn't have the disease or the trait."
The Correct Answer is C
Choice A reason: This option is incorrect because sickle cell disease is an inherited condition, and one parent having the trait is not sufficient for a child to have the disease.
Choice B reason: This option is also incorrect for the same reason as choice A; both parents must carry the trait for the child to have a chance of inheriting the disease.
Choice C reason: This is the correct choice. Sickle cell disease is inherited when both parents carry the sickle cell trait, giving their child a 25% chance of having the disease.
Choice D reason: This option is incorrect because if only one parent has sickle cell disease and the other has neither the disease nor the trait, the child cannot have sickle cell disease.

Correct Answer is B
Explanation
Choice A reason: Acute diarrhea and dehydration are not typical of Hirschsprung disease, which is characterized by bowel obstruction.
Choice B reason: This is the correct choice. Failure to pass meconium within the first 48 hours of life and abdominal distension are classic signs of Hirschsprung disease.
Choice C reason: Projectile vomiting and altered electrolytes could be signs of other conditions but are not specific to Hirschsprung disease.
Choice D reason: Currant jelly-like gelatinous stools and pain are more indicative of intussusception rather than Hirschsprung disease. Hirschsprung disease typically presents with a failure to pass stool and abdominal distension.
Correct Answer is C
Explanation
Choice A reason: Placing the infant flat and prone is not the first priority in the care of an infant with gastroschisis.
Choice B reason: While providing warmth and promoting bonding are important, they are not the immediate priority upon admission for an infant with gastroschisis.
Choice C reason: This is the correct choice. The exposed abdominal organs in gastroschisis must be protected immediately to prevent heat and fluid loss and to reduce the risk of infection.
Choice D reason: Breastfeeding is important for bonding and nutrition but is not the first intervention for an infant with gastroschisis.
