ATI Nursing Care of Children 2019 B

Correct Answer: B

Rationale: The correct answer is B: Hypertrophic pyloric stenosis. The "string sign" is associated with hypertrophic pyloric stenosis, a condition where the pyloric canal is narrowed, leading to gastric outlet obstruction. Intussusception (choice A) typically presents with colicky abdominal pain and currant jelly stools. Hirschsprung disease (choice C) is characterized by the absence of ganglion cells in the distal colon. Meckel diverticulum (choice D) is a congenital outpouching of the small intestine that can present with painless rectal bleeding.

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: C

Rationale: Hemolytic uremic syndrome is the most common cause of acute kidney injury in children. While dehydration can lead to prerenal acute kidney injury, it is not the most common cause in children. Glomerulonephritis is a common cause of chronic kidney disease but not typically the most common cause of acute kidney injury in children. Sepsis can lead to acute kidney injury, but in children, hemolytic uremic syndrome is more prevalent.

Correct Answer: C

Rationale: The correct recommendation for decreasing the number and total volume of emesis in an infant with gastroesophageal reflux is to thicken feedings and enlarge the nipple hole. Thicker feedings can reduce the frequency and volume of emesis by making the food less likely to be regurgitated. Enlarging the nipple hole helps ensure the thickened feedings can pass through. Surgical therapy (Choice A) is not the initial recommendation for managing gastroesophageal reflux in infants. Placing the infant in a prone position for sleep after feeding (Choice B) is not recommended due to the increased risk of sudden infant death syndrome (SIDS). Reducing the frequency of feeding by encouraging larger volumes of formula (Choice D) can exacerbate the reflux symptoms.

Correct Answer: B

Rationale: Postoperative teaching should focus on assessing bowel function to ensure the colostomy is functioning properly. This includes monitoring stool output, color, consistency, and signs of infection or blockage. Choice A, dilating the stoma, is not recommended without healthcare provider guidance, as it can lead to complications. Choice C, limitation of physical activities, may not be as crucial immediately after colostomy creation. Choice D, measures to prevent prolapse of the rectum, is more relevant for conditions like rectal prolapse and not specifically for a colostomy.
