What statement is most descriptive of Meckel diverticulum?

Correct Answer: B

Rationale: The correct answer is B. Meckel diverticulum often presents with intestinal bleeding, which can vary in severity. It is a congenital condition, meaning it is present from birth, not acquired during childhood (choice A). Meckel diverticulum is slightly more common in males than in females, so it does not occur more frequently in females (choice C). While some cases of Meckel diverticulum may require surgical intervention, medical interventions can also be sufficient to treat the problem, so it is not always necessary to resort to surgery (choice D).

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: 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.
