Nursing Elites

1. The nurse is teaching a group of students about myelination in a child. Which statement by the students indicates that the teaching was successful?

• A. Myelination continues into adolescence and beyond.
• B. The process occurs in a cephalocaudal (head-to-toe) pattern.
• C. Myelination decreases the speed of nerve impulses.
• D. Myelination decreases the specificity of nerve impulses.

Correct answer: B

Rationale: The correct answer is B. Myelination occurs in a cephalocaudal (head-to-toe) pattern, improving nerve function progressively. Choice A is incorrect as myelination continues into adolescence and beyond, not just during childhood. Choice C is incorrect because myelination actually increases the speed of nerve impulses rather than decreasing it. Choice D is incorrect as myelination enhances the specificity of nerve impulses, making them more efficient and precise rather than less specific.

2. A 4-year-old child is admitted with a diagnosis of bacterial pneumonia. What is the priority nursing intervention?

• A. Administering antipyretics
• B. Administering antibiotics
• C. Monitoring fluid intake
• D. Providing nutritional support

Correct answer: B

Rationale: The priority nursing intervention for a 4-year-old child admitted with bacterial pneumonia is administering antibiotics. Antibiotics are essential to treat the infection, prevent its spread, and avoid potential complications. Administering antipyretics (Choice A) may help reduce fever but does not address the underlying cause of pneumonia, which is bacterial in this case. Monitoring fluid intake (Choice C) is important to maintain hydration but does not directly treat the infection. Providing nutritional support (Choice D) is crucial for overall health, but the immediate priority is to address the bacterial infection with antibiotics to prevent further complications and promote recovery.

3. What is a common finding that the nurse can identify in most children with symptomatic cardiac malformations?

• A. Mental retardation
• B. Inherited genetic factors
• C. Delayed physical growth
• D. Clubbing of the fingertips

Correct answer: C

Rationale: Delayed physical growth is a common finding in most children with symptomatic cardiac malformations. This occurs due to inadequate oxygenation and nutrient supply to tissues as a result of the cardiac defect. Mental retardation (Choice A) is not typically associated with cardiac malformations unless there are complications affecting brain function. Inherited genetic factors (Choice B) may contribute to the development of cardiac malformations but are not a direct common finding in affected children. Clubbing of the fingertips (Choice D) is more commonly associated with chronic respiratory or cardiac conditions, not specifically cardiac malformations in children.

4. Which observation of the exposed abdomen is most indicative of pyloric stenosis?

• A. abdominal rigidity
• B. substernal retraction
• C. palpable olive-like mass
• D. marked distention of the lower abdomen

Correct answer: C

Rationale: In pyloric stenosis, a palpable olive-like mass in the abdomen is a classic finding. This mass is due to the hypertrophied pyloric muscle. Abdominal rigidity (choice A) is associated with conditions like peritonitis, substernal retraction (choice B) is typically seen in respiratory distress, and marked distention of the lower abdomen (choice D) is more characteristic of conditions like intestinal obstruction rather than pyloric stenosis.

5. The nurse is implementing care for a school-age child admitted to the pediatric intensive care unit with diabetic ketoacidosis (DKA). Which prescribed intervention should the nurse implement first?

• A. Begin 0.9% saline solution intravenously as prescribed
• B. Administer regular insulin intravenously as prescribed
• C. Place the child on a cardiac monitor
• D. Place the child on a pulse oximetry monitor

Correct answer: A

Rationale: The correct first intervention when managing a child with diabetic ketoacidosis is to begin intravenous saline solution to address dehydration and restore electrolyte balance. Rehydration is essential to improve perfusion and correct electrolyte imbalances. Administering insulin without addressing dehydration can potentially lead to further complications. Placing the child on a cardiac monitor or pulse oximetry monitor is important but not the initial priority in managing DKA.
