Nursing Elites

1. The charge nurse in the pediatric unit is teaching nursing students about pyloric stenosis. A student asks what causes pyloric stenosis. How should the nurse respond?

• A. One portion of the intestines invaginates or telescopes into another
• B. Hypertrophy of the circular pylorus muscle
• C. Relaxed cardiac sphincter
• D. Absent ganglion cells in the colon

Correct answer: B

Rationale: Pyloric stenosis is caused by the hypertrophy (thickening) of the circular muscle of the pylorus, leading to obstruction. Choice A is incorrect as it describes intussusception, not pyloric stenosis. Choice C is incorrect as a relaxed cardiac sphincter is related to gastroesophageal reflux. Choice D is incorrect as it describes Hirschsprung's disease, not pyloric stenosis.

2. The nurse is teaching a child experiencing severe edema associated with minimal change nephrotic syndrome about his diet. The nurse should discuss what dietary need?

• A. Consuming a regular diet
• B. Increasing protein
• C. Restricting fluids
• D. Decreasing calories

Correct answer: C

Rationale: Fluid restriction is often necessary to manage severe edema associated with MCNS. Increasing protein is not typically recommended due to the risk of exacerbating proteinuria, and calorie reduction is not generally needed.

3. A child with acetylsalicylic acid (aspirin) poisoning is being admitted to the emergency department. What early clinical manifestation does the nurse expect to assess on this child?

• A. Hematemesis
• B. Hematochezia
• C. Hyperglycemia
• D. Hyperventilation

Correct answer: D

Rationale: Early signs of aspirin poisoning include hyperventilation due to the stimulation of the respiratory center and the resultant respiratory alkalosis. Hematemesis, hematochezia, and hyperglycemia can occur later in the poisoning process or may not be directly related to aspirin toxicity.

4. The nurse is assisting a child with celiac disease to select foods from a menu. What foods should the nurse suggest?

• A. Hamburger patty with no bun
• B. Spaghetti with marinara sauce
• C. Corn on the cob with butter
• D. Rice cakes with hummus

Correct answer: C

Rationale: The correct answer is C: Corn on the cob with butter. Corn is a gluten-free option suitable for children with celiac disease. Choice A is incorrect because the bun contains gluten, so suggesting a hamburger patty without the bun is a better option. Choice B is not ideal as spaghetti often contains gluten, but spaghetti with marinara sauce could be a safer choice if the spaghetti is gluten-free. Choice D, rice cakes with hummus, is a gluten-free alternative, but corn on the cob is a more straightforward and common choice for children.

5. Which congenital heart defect causes a "boot-shaped" heart on a chest x-ray?

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

Correct answer: A

Rationale: The correct answer is A: Tetralogy of Fallot. Tetralogy of Fallot, a congenital heart defect with four distinct abnormalities, often presents with a "boot-shaped" heart on chest x-ray due to right ventricular hypertrophy. This characteristic finding is due to the specific combination of defects in this condition. Coarctation of the aorta (choice B), Transposition of the great arteries (choice C), and Ventricular septal defect (choice D) do not typically result in a "boot-shaped" heart on a chest x-ray like Tetralogy of Fallot does.
