What is the most likely cause of a 12-month-old's persistent diaper rash, characterized by perianal inflammation with bright red scaly plaques, small papules, and satellite lesions?
Infrequent diaper changes
Impetigo (staph)
Candida albicans (yeast)
Urine and feces
The Correct Answer is C
Choice A reason: Infrequent diaper changes can contribute to diaper rash, but the presence of satellite lesions suggests a yeast infection rather than a simple irritant rash.
Choice B reason: Impetigo, caused by staphylococcal or streptococcal bacteria, typically presents with honey-colored crusts and is not usually associated with satellite lesions.
Choice C reason: The description of bright red scaly plaques and satellite lesions is characteristic of a yeast infection, specifically caused by Candida albicans.
Choice D reason: While urine and feces can irritate the skin and cause diaper rash, the specific clinical findings mentioned point more towards a yeast infection.

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: Restricting calcium intake is not typically recommended for children with chronic renal failure as they may already be at risk for bone disease due to altered calcium metabolism.
Choice B reason: Eating three large meals per day and limiting snacks is not specific dietary advice for chronic renal failure; nutritional needs should be tailored to the individual.
Choice C reason: This is the correct choice. In chronic renal failure, the kidneys may not be able to remove excess potassium, leading to hyperkalemia, which can be dangerous.
Choice D reason: Increasing sodium intake is not generally recommended for chronic renal failure as it can contribute to hypertension and fluid retention.
