What is the most common cause of acute kidney injury in children?
- A. Dehydration
- B. Glomerulonephritis
- C. Hemolytic uremic syndrome
- D. Sepsis
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.

A child has been diagnosed with a Wilms tumor. What should preoperative nursing care include?
- A. Careful bathing and handling
- B. Monitoring of behavioral status
- C. Maintenance of strict isolation
- D. Administration of packed red blood cells
Correct Answer: A
Rationale: The correct answer is A: Careful bathing and handling. Preoperative care for a child with a Wilms tumor should focus on preventing any trauma to the abdomen, which could lead to tumor rupture. Monitoring behavioral status and maintaining strict isolation are not as critical in this situation. Behavioral status is important but not a priority in preoperative care for a Wilms tumor. Strict isolation is not necessary unless there are specific infectious concerns, which is not typically the case for a Wilms tumor. Administration of packed red blood cells is not a standard preoperative intervention for Wilms tumor.
What is the purpose of using cimetidine (Tagamet) for gastroesophageal reflux?
- A. The medication reduces gastric acid secretion.
- B. The medication neutralizes the acid in the stomach.
- C. The medication increases the rate of gastric emptying time.
- D. The medication coats the lining of the stomach and esophagus.
Correct Answer: A
Rationale: The correct answer is A. Cimetidine (Tagamet) is an H2 receptor antagonist that works by reducing gastric acid secretion. This action helps to decrease the acidity in the stomach, which in turn reduces the symptoms of gastroesophageal reflux. Choice B is incorrect because cimetidine does not neutralize acid but rather decreases its production. Choice C is incorrect as cimetidine does not affect the rate of gastric emptying time. Choice D is incorrect as cimetidine does not coat the lining of the stomach and esophagus but instead works to reduce gastric acid secretion.
What clinical manifestation should be the most suggestive of acute appendicitis?
- A. Rebound tenderness
- B. Bright red or dark red rectal bleeding
- C. Abdominal pain that is relieved by eating
- D. Colicky, cramping abdominal pain around the umbilicus
Correct Answer: D
Rationale: The correct answer is D: Colicky, cramping abdominal pain around the umbilicus. This type of pain is a common early sign of acute appendicitis. Rebound tenderness, choice A, is a later sign seen in the physical examination of a patient with appendicitis. Rectal bleeding, as described in choice B, is not typically associated with appendicitis. Abdominal pain that is relieved by eating, as mentioned in choice C, is more indicative of peptic ulcer disease rather than appendicitis.
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.
The nurse is caring for an infant who had surgical repair of a tracheoesophageal fistula 24 hours ago. Gastrostomy feedings have not been started. What do nursing actions related to the gastrostomy tube include?
- A. Keep the tube clamped.
- B. Suction the tube as needed.
- C. Leave the tube open to gravity drainage.
- D. Secure the tube with tape.
Correct Answer: C
Rationale: Leaving the gastrostomy tube open to gravity drainage prevents the accumulation of air and fluids, reducing the risk of complications such as vomiting or aspiration in the immediate postoperative period. Keeping the tube clamped or suctioning it can lead to pressure buildup, increasing the risk of complications. Securing the tube with tape is important but not the primary action related to the gastrostomy tube in this case.
