1. Which pediatric condition is characterized by a "string sign" on an upper GI series?

• A. Intussusception
• B. Hypertrophic pyloric stenosis
• C. Hirschsprung disease
• D. Meckel diverticulum

Correct answer: B

Rationale: The correct answer is B: Hypertrophic pyloric stenosis. The "string sign" is associated with hypertrophic pyloric stenosis, a condition where the pyloric canal is narrowed, leading to gastric outlet obstruction. Intussusception (choice A) typically presents with colicky abdominal pain and currant jelly stools. Hirschsprung disease (choice C) is characterized by the absence of ganglion cells in the distal colon. Meckel diverticulum (choice D) is a congenital outpouching of the small intestine that can present with painless rectal bleeding.

2. The nurse observes that a newborn is having problems after birth. What should indicate a tracheoesophageal fistula?

• A. Jitteriness
• B. Meconium ileus
• C. Excessive frothy saliva
• D. Increased need for sleep

Correct answer: C

Rationale: Excessive frothy saliva is a hallmark sign of tracheoesophageal fistula. The abnormal connection between the esophagus and trachea causes difficulty in swallowing, leading to an accumulation of saliva in the mouth. This symptom is crucial for early identification and management of tracheoesophageal fistula. Choices A, B, and D are incorrect as they are not specific indicators of tracheoesophageal fistula.

3. The nurse is providing anticipatory guidance to parents of a 4-month-old infant on preventing an aspiration injury. What should the nurse include in the teaching?

• A. Keep baby powder out of reach.
• B. Inspect toys for removable parts.
• C. Allow the infant to take a bottle to bed.
• D. Teething biscuits can be used for teething discomfort.

Correct answer: A

Rationale: Baby powder can be inhaled by the infant and cause respiratory distress. Toys should be inspected to prevent choking hazards. Allowing an infant to take a bottle to bed can increase the risk of aspiration, and hard foods like teething biscuits should be given with caution.

4. What amount of fluid loss occurs with moderate dehydration?

• A. <50 ml/kg
• B. 50 to 90 ml/kg
• C. <5% total body weight
• D. >15% total body weight

Correct answer: B

Rationale: Moderate dehydration is typically defined as a loss of 50 to 90 mL/kg of body weight. This amount reflects significant fluid loss that requires medical attention but is not yet severe.

5. What is the primary goal in the treatment of a child with nephrotic syndrome?

• A. Decrease urine output
• B. Increase serum albumin
• C. Reduce proteinuria
• D. Increase blood pressure

Correct answer: C

Rationale: The primary goal in treating nephrotic syndrome in children is to reduce proteinuria. Nephrotic syndrome is characterized by proteinuria, leading to hypoalbuminemia and edema. By reducing proteinuria, kidney damage can be minimized, and symptoms can be managed effectively. Decreasing urine output (Choice A) is not the primary goal, as it does not address the underlying issue of protein loss. Increasing serum albumin (Choice B) is a consequence of reducing proteinuria rather than the primary goal. Increasing blood pressure (Choice D) is not a goal in treating nephrotic syndrome and may even be contraindicated to prevent further kidney damage.
