One of the major differences in clinical presentation between Crohn disease (CD) and ulcerative colitis (UC) is that UC is more likely to cause which clinical manifestation?

Correct Answer: B

Rationale: Rectal bleeding is more commonly associated with ulcerative colitis (UC) than with Crohn disease (CD). While both conditions can cause abdominal pain and growth issues, bleeding is a hallmark of UC due to its superficial mucosal inflammation. Perianal lesions are more characteristic of CD, and growth retardation is typically not a direct clinical manifestation of either CD or UC.

Correct Answer: A

Rationale: Teaching about coping with stress and adjusting to chronic illness is crucial for adolescents with Crohn disease. CD is a chronic condition with no cure, so focusing on managing the disease, stress, and diet is essential for improving the adolescent's quality of life. Choice B is incorrect because Crohn disease cannot be cured surgically. Choice C is relevant but not as essential as coping with stress and chronic illness. Choice D is not a priority in teaching an adolescent with Crohn disease as it mainly focuses on preventing the spread of illness to others, which is not a significant concern with CD, and high-fiber diets may not always be suitable for individuals with this condition.

Correct Answer: D

Rationale: Excessive vomiting in pyloric stenosis leads to the loss of stomach acid (hydrochloric acid), resulting in metabolic alkalosis, not hyperkalemia, hyperchloremia, or metabolic acidosis. Metabolic alkalosis is characterized by a higher pH level in the blood due to the loss of acid and a relative increase in bicarbonate. Hyperkalemia is an elevated level of potassium in the blood and is not directly related to excessive vomiting in pyloric stenosis. Hyperchloremia is an excess of chloride in the blood, which is not typically associated with this condition. Metabolic acidosis is a condition characterized by a lower pH level in the blood, caused by an excess of acid or a loss of bicarbonate, which is not the typical complication seen in pyloric stenosis with excessive vomiting.

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: C

Rationale: Popcorn is a safe snack for a child with celiac disease as it is naturally gluten-free. Other options like pizza, pretzels, and oatmeal cookies typically contain gluten unless specifically made with gluten-free ingredients, which can exacerbate celiac symptoms. Therefore, popcorn is the best option to suggest to the child to avoid any adverse effects on their condition.
