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 caring for a child with Meckel diverticulum. What type of stool does the nurse expect to observe?

• A. Steatorrhea
• B. Clay-colored
• C. Currant jelly-like
• D. Loose stools with undigested food

Correct answer: C

Rationale: Corrected Rationale: Currant jelly-like stools, which contain blood and mucus, are characteristic of Meckel diverticulum. This symptom occurs due to the bleeding from the ectopic gastric mucosa present in the diverticulum. Steatorrhea (choice A) is not typically associated with Meckel diverticulum. Clay-colored stools (choice B) are seen in conditions affecting the biliary system. Loose stools with undigested food (choice D) may indicate malabsorption issues, but it is not specifically linked to Meckel diverticulum.

3. In which type of cancer are the urinary excretion of the breakdown products of catecholamines, especially vanillylmandelic acid (VMA) and homovanillic acid (HVA), detected?

• A. Neuroblastoma
• B. Nephroblastoma
• C. Leukemia
• D. Osteosarcoma

Correct answer: A

Rationale: The correct answer is A: Neuroblastoma. Neuroblastoma, a cancer that arises from nerve tissue, is associated with increased levels of catecholamine metabolites, including VMA and HVA, in the urine. Nephroblastoma (Wilms tumor) is a type of kidney cancer and is not typically associated with elevated levels of catecholamine breakdown products. Leukemia is a cancer of the blood and bone marrow and does not lead to increased VMA and HVA excretion in urine. Osteosarcoma is a bone cancer and is not linked to elevated levels of catecholamine metabolites in the urine.

4. Which of the following conditions is characterized by a 'machine-like' murmur in children?

• A. Patent ductus arteriosus
• B. Ventricular septal defect
• C. Atrial septal defect
• D. Coarctation of the aorta

Correct answer: A

Rationale: The correct answer is A, Patent ductus arteriosus. This condition is characterized by a continuous 'machine-like' murmur due to abnormal blood flow between the aorta and pulmonary artery. Ventricular septal defect (choice B) is characterized by a harsh holosystolic murmur, atrial septal defect (choice C) typically presents with a fixed split S2 and a pulmonary flow murmur, and coarctation of the aorta (choice D) is associated with a systolic murmur in the back and bilateral lower extremities.

5. The nurse is caring for a non-English-speaking child and family. Which should the nurse consider when using an interpreter?

• A. Pose several questions at a time
• B. Use medical jargon when possible
• C. Communicate directly with family members when asking questions
• D. Carry on some communication in English with the interpreter about the family's needs

Correct answer: C

Rationale: The nurse should communicate directly with the family members when asking questions, ensuring the interpreter translates accurately without adding or omitting information.
