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 would indicate that the treatment has been effective?
Decreased stridor
Decreased temperature
Barking cough
Improved hydration
The Correct Answer is A
Choice A rationale
Acute laryngotracheobronchitis, also known as croup, is a common childhood condition that is usually caused by a viral infection. The main symptom is a distinctive barking cough. A cool mist tent can help to soothe the inflamed airways and reduce stridor, which is a high-pitched,
wheezing sound caused by disrupted airflow. Therefore, decreased stridor would indicate that the treatment has been effective.
Choice B rationale
While a decreased temperature might indicate a resolution of any underlying infection, it is not directly related to the effectiveness of a cool mist tent in treating acute laryngotracheobronchitis.
Choice C rationale
A barking cough is a symptom of acute laryngotracheobronchitis and does not indicate treatment effectiveness.
Choice D rationale
Improved hydration is important but is not a direct indicator of the effectiveness of the cool mist tent.

Cancer and certain treatments for cancer can weaken the immune system, increasing the risk of infections that could lead to sepsis.

Kallmann’s syndrome is a genetic condition that affects the production of a hormone involved in sexual development. It does not significantly increase the risk of sepsis.
Choice D rationale

Correct Answer is D
Explanation
Choice A rationale
Lubricating the suction catheter tip with sterile saline is not recommended because it can introduce bacteria into the tracheostomy tube and cause infection.
Choice B rationale
Hyperventilating the patient on 100% oxygen prior to suctioning is not necessary and can cause complications such as oxygen toxicity.
Choice C rationale
Performing chest physiotherapy prior to suctioning is not typically done during tracheostomy care. Chest physiotherapy is a separate procedure that involves physical techniques to remove mucus from the respiratory tract.
Choice D rationale
Suctioning two to three times with a 60-second pause between passes is the correct action. This helps to remove secretions effectively without causing hypoxia.
