Nursing Elites

1. A 6-month-old infant with Hirschsprung disease is scheduled for a temporary colostomy. What should postoperative teaching to the parents include?

• A. Dilating the stoma
• B. Assessing bowel function
• C. Limitation of physical activities
• D. Measures to prevent prolapse of the rectum

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.

2. Which pediatric disorder is associated with a 'boot-shaped' heart on a chest x-ray?

• A. Tetralogy of Fallot
• B. Transposition of the great arteries
• C. Coarctation of the aorta
• D. Ventricular septal defect

Correct answer: A

Rationale: The correct answer is A: Tetralogy of Fallot. Tetralogy of Fallot is often associated with a 'boot-shaped' heart appearance on a chest x-ray due to the characteristic heart anatomy in this condition. This appearance is caused by the combination of pulmonary stenosis, overriding aorta, ventricular septal defect, and right ventricular hypertrophy. Choice B, Transposition of the great arteries, is incorrect because it presents with a 'egg-on-a-string' appearance on x-ray due to the abnormal position of the aorta and pulmonary artery. Choice C, Coarctation of the aorta, typically presents with rib notching on x-ray. Choice D, Ventricular septal defect, does not produce the 'boot-shaped' heart appearance seen in Tetralogy of Fallot.

3. Which physiological acid-base balance complication would be most important for the nurse to assess in a patient with diarrhea?

• A. High serum pH
• B. Normal serum pH
• C. Metabolic alkalosis
• D. Metabolic acidosis

Correct answer: D

Rationale: The correct answer is metabolic acidosis. Diarrhea can lead to the loss of bicarbonate, causing an imbalance in the acid-base status of the body, specifically resulting in metabolic acidosis. High serum pH (choice A) is incorrect as diarrhea-induced bicarbonate loss would lower pH, not increase it. Normal serum pH (choice B) is not the best answer as diarrhea can disrupt the acid-base balance. Metabolic alkalosis (choice C) is an alkaline state, which is less likely to be caused by diarrhea.

4. Play activities of the preschool-age child include:

• A. Having imaginary playmates
• B. Selective collection of objects
• C. Complex board games
• D. Associative play

Correct answer: A

Rationale: The correct answer is A, 'Having imaginary playmates.' Preschool-age children often engage in imaginative play, which includes creating imaginary friends or playmates. This type of play helps them develop creativity, social skills, and emotional expression. Choice B, 'Selective collection of objects,' may be more common in older children and is not a typical play activity for preschoolers. Choice C, 'Complex board games,' are usually beyond the developmental level of preschoolers as they require more advanced cognitive skills. Choice D, 'Associative play,' is a term used to describe a type of play where children play alongside each other but not necessarily together, which is different from the imaginative play involving imaginary playmates that preschoolers often engage in.

5. Which pediatric condition is characterized by a "string sign" on an upper GI series?

• A. Intussusception
• B. Hypertrophic pyloric stenosis
• C. Hirschsprung disease
• D. Meckel diverticulum

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.
