Correct Answer: B

Rationale: Constipation is the most common cause of abdominal pain in school-aged children. It is often due to dietary factors such as low fiber intake or insufficient fluid consumption. Chronic constipation can lead to complications like fecal impaction and soiling, highlighting the importance of early recognition and treatment. Gastroenteritis, although common, typically presents with diarrhea and vomiting. Appendicitis is more common in adolescents and typically presents with right lower quadrant pain. Irritable bowel syndrome is less common in children and is characterized by recurrent abdominal pain associated with defecation.

Correct Answer: C

Rationale: Croup is the correct answer. It is characterized by a distinctive "barking" cough, typically worse at night, caused by the inflammation of the upper airway, specifically the larynx and trachea. Asthma (Choice A) typically presents with wheezing and shortness of breath rather than a barking cough. Bronchiolitis (Choice B) commonly causes wheezing and respiratory distress in infants and young children. Pneumonia (Choice D) often presents with symptoms like fever, productive cough, and chest pain, but not typically a barking cough.

Correct Answer: B

Rationale: Celiac disease often presents with steatorrhea, malnutrition, and foul-smelling stools due to the malabsorption of nutrients. Therefore, all the manifestations listed (steatorrhea, malnutrition, foul-smelling stools) are expected in a child with celiac disease. Polycythemia is not associated with celiac disease, making choice B the correct answer.

Correct Answer: B

Rationale: The correct answer is B: Increased protein. Children with Crohn's disease require a diet high in protein to support growth and tissue repair. High fiber should be avoided as it can exacerbate symptoms of Crohn's disease. Reducing calories can lead to malnutrition, which is detrimental in this condition. Herbal supplements should be used cautiously and only under medical advice as they may interact with medications or worsen symptoms.

Correct Answer: D

Rationale: Sweating is indeed one of the earliest signs of hypoglycemia in children with Type 1 diabetes. When blood sugar levels drop too low, the body releases stress hormones like adrenaline, which can lead to sweating. While irritability, rapid heartbeat, and confusion can also be seen in hypoglycemia, sweating is particularly common as a quick indicator of low blood sugar levels in children with Type 1 diabetes.
