A nurse is caring for a toddler who has acute laryngotracheobronchitis and has been placed in a cool mist tent. Which of the following findings should indicate to the nurse that the treatment is effective?
Barking cough
Decreased stridor
Decreased temperature
Improved hydration
The Correct Answer is B
Choice A reason: Barking cough is not a finding that indicates the effectiveness of the treatment. Barking cough is a sign of inflammation of the larynx and trachea, which causes a hoarse and harsh sound. It is a common symptom of acute laryngotracheobronchitis, also known as croup.
Choice B reason: Decreased stridor is a finding that indicates the effectiveness of the treatment. Stridor is a high-pitched, wheezing sound that occurs when the airway is narrowed or obstructed. It is a sign of respiratory distress and hypoxia. The cool mist tent helps to humidify and soothe the airway, reducing the swelling and inflammation.
Choice C reason: Decreased temperature is not a finding that indicates the effectiveness of the treatment. Decreased temperature could be a sign of hypothermia or sepsis, which are serious complications that require immediate attention. The normal temperature range for a toddler is 36.5°C to 37.5°C (97.7°F to 99.5°F).
Choice D reason: Improved hydration is not a finding that indicates the effectiveness of the treatment. Improved hydration is a sign of adequate fluid intake and output, which are important for maintaining electrolyte balance and preventing dehydration. However, hydration status does not directly affect the airway inflammation or obstruction.

Correct Answer is B
Explanation
Choice A reason: Hypertrophic pyloric stenosis is a condition in which the pyloric sphincter becomes thickened and obstructs the passage of food from the stomach to the duodenum. It causes projectile vomiting, dehydration, and weight loss, but not a palpable mass or bloody stools.
Choice B reason: Intussusception is a condition in which a segment of the intestine telescopes into another segment, causing obstruction, inflammation, and ischemia. It causes a palpable mass in the upper right quadrant, abdominal pain, and stools mixed with blood and mucus, also known as "currant jelly" stools.
Choice C reason: Inguinal hernia is a condition in which a part of the intestine protrudes through a weak spot in the abdominal wall near the inguinal canal. It causes a bulge in the groin area, especially when the infant cries or strains. It does not cause a mass in the upper right quadrant or bloody stools.
Choice D reason: Tracheoesophageal fistula is a congenital anomaly in which there is an abnormal connection between the trachea and the esophagus. It causes excessive drooling, choking, coughing, and cyanosis during feeding, but not a palpable mass or bloody stools.
Correct Answer is C
Explanation
Choice A reason: Red currant jelly stools are typically associated with intussusception, not pyloric stenosis. In pyloric stenosis, the stool would not have this appearance.
Choice B reason: Distended neck veins are not a clinical manifestation of pyloric stenosis. They are more commonly associated with cardiac or respiratory issues.
Choice C reason: Projectile vomiting is a classic symptom of pyloric stenosis. It occurs due to the obstruction at the pylorus, which prevents stomach contents from passing into the small intestine.
Choice D reason: A bulged abdomen is not specific to pyloric stenosis. While the abdomen may appear full, 'bulged' is not the precise term used to describe the manifestation in pyloric stenosis.
