What are the earliest recognizable clinical manifestations of cystic fibrosis (CF)?
Meconium ileus.
Foul-smelling, frothy, greasy stools.
History of poor intestinal absorption.
Recurrent pneumonia and lung infections.
The Correct Answer is A
The correct answer is choice A. Meconium ileus.
Choice A rationale:
Meconium ileus. This is the earliest recognizable clinical manifestation of cystic fibrosis (CF). Meconium ileus refers to the blockage of the small intestine by thick, sticky meconium, the earliest stool of a newborn. It occurs in the first 24-48 hours of life and can be a sign of underlying cystic fibrosis.
Choice B rationale:
Foul-smelling, frothy, greasy stools. Foul-smelling, frothy, greasy stools are characteristic of malabsorption, which can occur in cystic fibrosis. However, this manifestation typically appears after meconium ileus and is not the earliest recognizable clinical sign.
Choice C rationale:
History of poor intestinal absorption. While poor intestinal absorption is a common consequence of cystic fibrosis, it is not one of the earliest recognizable clinical manifestations. Meconium ileus takes precedence as the primary early sign.
Choice D rationale:
Recurrent pneumonia and lung infections. Recurrent pneumonia and lung infections are common in later stages of cystic fibrosis due to the buildup of thick mucus in the respiratory tract. However, they are not among the earliest recognizable clinical manifestations of the disease. Meconium ileus is the earliest indicator in this context.

Correct Answer is C
Explanation
The correct answer is choice C. The child needs opportunities to play with peers.
Choice A rationale:
While it's important for children with congenital heart disease to understand their limitations, it's not the primary concern in this scenario. Allowing the child to interact and play with peers is essential for their social, emotional, and psychological development.
Choice B rationale:
While parents play a crucial role in a child's care, completely isolating the child from peers is not ideal. Overprotectiveness can lead to social isolation and hinder the child's ability to develop important social skills.
Choice C rationale:
Children with congenital heart disease should be encouraged to engage in age-appropriate physical activities and play with peers. Of course, the level of activity should be discussed with the child's healthcare provider, but limiting the child's interactions could have negative consequences on their overall development and emotional well-being.
Choice D rationale:
While supervision is important for any child's safety, constant parental supervision to avoid overexertion might not be necessary or feasible. Educating the child about their limitations and providing opportunities for play while monitoring their comfort level is a more balanced approach.
Correct Answer is A
Explanation
The correct answer is choice A: Rotavirus.
Choice A rationale:
Rotavirus is a viral pathogen that frequently causes acute diarrhea in young children. It is highly contagious and is responsible for a significant portion of severe diarrhea cases worldwide. Rotavirus infections are most common in infants and young children, and they can lead to dehydration, especially in developing countries where access to clean water and proper sanitation might be limited.
Choice B rationale:
Salmonella organisms can cause food poisoning and gastrointestinal infections that lead to diarrhea. However, they are more commonly associated with bacterial infections rather than viral-induced acute diarrhea.
Choice C rationale:
Shigella organisms are also bacterial pathogens that cause diarrhea, specifically bacillary dysentery. While they can cause severe diarrhea, they are not the viral pathogen typically responsible for acute diarrhea in young children.
Choice D rationale:
Giardia organisms are parasites that can cause gastrointestinal infections leading to diarrhea. However, they are not viruses, and they are less commonly associated with acute diarrhea in children compared to rotavirus.
