Rationale: Childhood obesity is a prevalent issue in children with Down syndrome due to factors such as decreased physical activity, slower metabolism, and potential overeating tendencies. Addressing obesity is crucial to promoting healthy lifestyles and preventing associated health complications. Rickets, a condition caused by a deficiency of vitamin D, is not commonly associated with Down syndrome. While anemia can occur in individuals with Down syndrome, obesity is a more common concern. Rumination, the regurgitation of food without nausea, is not a typical nutritional problem in children with Down syndrome.

Correct Answer: B

Rationale: Lifting the baby from under the armpits can cause fractures in infants with osteogenesis imperfecta.

Rationale: Phenylketonuria (PKU) is suggested by a mousy or musty odor of the urine, caused by the inability to metabolize phenylalanine. Maple syrup urine disease (Choice A) is characterized by a sweet-smelling urine. Tyrosinemia (Choice B) presents with cabbage-like odor in the urine. Trimethylaminuria (Choice D) results in a fishy odor in the urine, breath, and sweat.

Rationale: Tachypnea, which refers to rapid breathing, is an early sign of congestive heart failure. In heart failure, the heart's inability to pump efficiently can lead to fluid accumulation in the lungs, causing the child to breathe faster to try to compensate for the decreased oxygen exchange. Bradycardia (slow heart rate) is not typically associated with congestive heart failure; instead, it may indicate a different issue. Inability to sweat is not a common early sign of congestive heart failure. Increased urinary output is not a typical early sign of congestive heart failure; instead, it may be a sign of other conditions like diabetes or kidney issues.

Correct Answer: B

Rationale: Assessing the child's dietary intake is crucial in managing symptoms and ensuring proper nutrition in children with ADHD. Dietary factors can influence ADHD symptoms.
