1. What condition is the most common cause of acute renal failure in children?

• A. Pyelonephritis
• B. Tubular destruction
• C. Severe dehydration
• D. Upper tract obstruction

Correct answer: C

Rationale: Severe dehydration is the most common cause of acute renal failure in children, as it leads to prerenal azotemia, which can progress to renal failure if not corrected. Other causes like pyelonephritis and tubular destruction are less common and usually secondary to other conditions.

2. When transitioning from intravenous to oral morphine, what would the nurse anticipate regarding the oral dose in comparison to the intravenous dose to achieve equianalgesia?

• A. Same as the intravenous dose
• B. Greater than the intravenous dose
• C. One half of the intravenous dose
• D. One fourth of the intravenous dose

Correct answer: B

Rationale: When switching from intravenous to oral morphine, a higher oral dose is required to achieve equianalgesia due to significant metabolism from the first-pass effect. Choosing the same oral dose as the intravenous dose would provide less pain relief. Opting for a dose greater than the intravenous dose is necessary to achieve the same analgesic effect. Therefore, options A, C, and D are incorrect.

3. A 14-month-old child is admitted to the hospital with laryngotracheobronchitis (LTB). Which assessment findings should the nurse expect?

• A. Cyanosis and dyspnea
• B. Productive cough and high fever
• C. Barking cough and inspiratory stridor
• D. Pale laryngeal and dyspnea

Correct answer: C

Rationale: The correct answer is C: 'Barking cough and inspiratory stridor.' Classic signs of laryngotracheobronchitis (LTB) include a barking cough, often described as a seal-like cough, and inspiratory stridor, which is a high-pitched sound heard during inspiration. These symptoms occur due to inflammation and narrowing of the upper airway. Choices A, B, and D are incorrect as they do not align with the typical assessment findings of LTB. Cyanosis and dyspnea (Choice A) may occur in severe cases but are not specific to LTB. Productive cough and high fever (Choice B) are more indicative of lower respiratory tract infections. Pale laryngeal and dyspnea (Choice D) are not characteristic findings of LTB.

4. What is a priority intervention for an infant with a temporary colostomy for Hirschsprung disease?

• A. Teaching how to irrigate the colostomy
• B. Protecting the skin around the colostomy
• C. Discussing the implications of a colostomy during puberty
• D. Using simple, straightforward language to prepare the child

Correct answer: B

Rationale: Protecting the skin around the colostomy is crucial to prevent irritation and infection, which are common complications in infants with colostomies. Teaching and discussing long-term implications are important but secondary to immediate skin care needs.

5. 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.
