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 D
Explanation
Choice A reason: This statement is normal, as an infant who is 2 months old should have an axillary temperature between 36.5°C and 37.5°C (97.7°F and 99.5°F). The nurse should assess the infant's temperature using an axillary or tympanic method, as oral and rectal methods are not recommended for infants.
Choice B reason: This statement is normal, as an infant who is 2 months old should have a heart rate between 100 and 160 beats per minute. The nurse should assess the infant's heart rate by auscultating the apical pulse for a full minute.
Choice C reason: This statement is normal, as an infant who is 2 months old should have a respiratory rate between 25 and 40 breaths per minute. The nurse should assess the infant's respiratory rate by observing the chest movements for a full minute.
Choice D reason: This statement is abnormal, as an infant who is 2 months old should have a weight gain of about 150 to 200 grams (5 to 7 ounces) per week. The current weight of the infant indicates a failure to thrive, as it is below the 5th percentile for the age and gender. The nurse should report this finding to the provider and assess the infant's feeding habits, growth chart, and developmental milestones.
Correct Answer is D
Explanation
Choice A reason: This statement is incorrect, as montelukast is a leukotriene receptor antagonist that is used for long-term control and prevention of asthma symptoms. It is not effective for acute asthma attacks, as it does not provide immediate bronchodilation.
Choice B reason: This statement is incorrect, as budesonide is an inhaled corticosteroid that is used for long-term control and prevention of inflammation in asthma. It is not effective for acute asthma attacks, as it does not provide immediate relief of bronchospasm.
Choice C reason: This statement is incorrect, as prednisone is an oral corticosteroid that is used for short-term treatment of severe asthma exacerbations. It is not effective for acute asthma attacks, as it takes several hours to exert its anti-inflammatory effect.
Choice D reason: This statement is correct, as albuterol is a short-acting beta2 agonist that is used for quick relief of acute asthma symptoms. It provides rapid bronchodilation by relaxing the smooth muscles of the airways.
