What term describes the invagination of one segment of bowel within another?

Correct Answer: D

Rationale: Intussusception is the correct answer. It refers to the condition where one segment of the bowel folds into another, leading to an obstruction. Atresia (Choice A) is the absence or abnormal closure of a normal opening or tubular structure. Stenosis (Choice B) is the narrowing of a passage in the body. Herniation (Choice C) is the abnormal protrusion of an organ or tissue through a defect in its surrounding walls. Intussusception is a medical emergency commonly observed in infants and young children and necessitates prompt intervention to prevent severe complications.

Correct Answer: A

Rationale: Dry mucous membranes are a common sign of moderate dehydration in children, indicating a loss of bodily fluids. When a child is moderately dehydrated, the mucous membranes in the mouth and nose may appear dry. This condition can occur due to various factors such as vomiting, diarrhea, or inadequate fluid intake. Normal capillary refill (choice B) is not typically associated with dehydration; it is a measure of circulatory status. Hyperactive bowel sounds (choice C) can be present in conditions like gastroenteritis but are not specific to dehydration. Edema (choice D) is the retention of fluid in the body and is not a typical sign of dehydration.

Correct Answer: C

Rationale: The correct answer is C, 'Tripod.' In children with epiglottitis, the tripod position is recommended to help open the airway and ease breathing. This position involves the child sitting upright, leaning forward, and supporting themselves with their hands on their knees or another surface. This posture helps improve air entry into the lungs by maximizing the space for breathing. Choices A (Supine), B (Prone), and D (Semi-Fowler's) are incorrect. Placing a child with epiglottitis in the supine position may further obstruct the airway, while the prone position and semi-Fowler's position do not facilitate optimal air exchange in these cases.

Correct Answer: C

Rationale: Excessive frothy saliva is a hallmark sign of tracheoesophageal fistula. The abnormal connection between the esophagus and trachea causes difficulty in swallowing, leading to an accumulation of saliva in the mouth. This symptom is crucial for early identification and management of tracheoesophageal fistula. Choices A, B, and D are incorrect as they are not specific indicators of tracheoesophageal fistula.

Correct Answer: D

Rationale: The correct answer is D: Colicky, cramping abdominal pain around the umbilicus. This type of pain is a common early sign of acute appendicitis. Rebound tenderness, choice A, is a later sign seen in the physical examination of a patient with appendicitis. Rectal bleeding, as described in choice B, is not typically associated with appendicitis. Abdominal pain that is relieved by eating, as mentioned in choice C, is more indicative of peptic ulcer disease rather than appendicitis.

Correct Answer: A

Rationale: The primary treatment goal for a child with juvenile idiopathic arthritis is pain management. Juvenile idiopathic arthritis is a chronic condition with no known cure, making pain management crucial to improve the quality of life for these children. While reducing joint deformity and physical therapy are important aspects of managing the condition, the primary focus is on alleviating pain and improving function.

Correct Answer: C

Rationale: A high-calorie diet is recommended for children with cystic fibrosis due to their increased energy needs and malabsorption issues. Cystic fibrosis affects the pancreas, leading to poor digestion and absorption of nutrients, particularly fats, which requires dietary adjustments to maintain adequate nutrition. High carbohydrate (Choice A) is not the primary focus; the emphasis is on overall calorie intake. Low protein (Choice B) is not recommended as protein intake is essential for growth and development. Low fat (Choice D) is not the best option as fat-soluble vitamin absorption is already compromised in cystic fibrosis, hence fat restriction is not a priority.

Correct Answer: A

Rationale: Respiratory infections are the leading cause of morbidity and mortality in children with cystic fibrosis. Cystic fibrosis primarily affects the respiratory system, leading to thick mucus buildup in the lungs, which predisposes these children to recurrent respiratory infections. Malnutrition and diabetes are common comorbidities in cystic fibrosis but are not the leading causes of morbidity and mortality in affected children. Liver disease can occur in cystic fibrosis but is less common than respiratory complications.

Correct Answer: B

Rationale: The correct answer is B: Stress management may be helpful. Stress is known to exacerbate symptoms of irritable bowel syndrome (IBS), making stress management an essential part of managing the condition. While dietary modifications can also be beneficial, a low-fiber diet is not universally recommended for IBS, as fiber can be important for some individuals. Milk products may or may not be contributing factors, as food triggers can vary among individuals. Pantoprazole, a proton pump inhibitor, is not typically the first-line treatment for IBS, as it is more commonly used for conditions like gastroesophageal reflux disease.
