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 indicates that the treatment has been effective?
Decreased stridor
Improved hydration
Decreased temperature
Barking cough
The Correct Answer is A
Choice A reason:
Decreased stridor: Stridor is a high-pitched, wheezing sound caused by disrupted airflow. In acute laryngotracheobronchitis (croup), stridor is a common symptom due to inflammation and narrowing of the airways. The effectiveness of treatment, such as a cool mist tent, is often indicated by a reduction in stridor, as it suggests that the airway inflammation is decreasing and the airflow is improving.
Choice B reason:
Improved hydration: While maintaining hydration is important in managing croup, it is not a direct indicator of the effectiveness of the cool mist tent treatment. Improved hydration can be achieved through various means, such as oral fluids or intravenous therapy, and does not specifically reflect the reduction of airway inflammation.
Choice C reason:
Decreased temperature: Fever can be a symptom of croup, but a decrease in temperature is not a primary indicator of the effectiveness of the cool mist tent treatment. The main goal of the cool mist tent is to reduce airway inflammation and improve breathing, rather than to control fever.
Choice D reason:
Barking cough: A barking cough is a characteristic symptom of croup. While the cool mist tent can help soothe the airways and reduce coughing, the presence or absence of a barking cough alone is not a definitive indicator of treatment effectiveness. The primary focus is on reducing airway obstruction and improving airflow.

Correct Answer is A
Explanation
Choice A Reason:
“I’m glad that my child’s ostomy is only temporary.” This statement indicates an understanding of the teaching because, in many cases, the ostomy created during the initial surgery for Hirschsprung disease is temporary. The initial surgery often involves creating a stoma to divert stool while the affected portion of the intestine heals. Once healing is complete, a second surgery is performed to reconnect the healthy sections of the intestine.
Choice B Reason:
“I want to learn how to empty my child’s urinary catheter bag.” This statement does not indicate an understanding of the teaching related to Hirschsprung disease, as urinary catheters are not typically associated with this condition. Hirschsprung disease affects the colon and rectum, not the urinary system.
Choice C Reason:
“I’m glad my child will have normal bowel movements now.” While this statement shows optimism, it does not fully reflect an understanding of the teaching. After the initial surgery, the child may still experience irregular bowel movements until the second surgery is completed and the bowel function is fully restored.
Choice D Reason:
“I want to learn how to use my child’s feeding tube as soon as possible.” This statement is not relevant to Hirschsprung disease, as feeding tubes are not typically required for this condition. Hirschsprung disease primarily affects bowel movements and does not usually necessitate the use of a feeding tube.
Correct Answer is B
Explanation
Choice A Reason:
The statement “Spray countertops and sinks with insecticide” is not recommended. Head lice primarily live on the human scalp and do not survive long on inanimate surfaces. Therefore, spraying countertops and sinks with insecticide is unnecessary and could expose children and pets to harmful chemicals.
Choice B Reason:
The statement “Seal nonwashable items in airtight plastic bags” is correct. Sealing items that cannot be washed in airtight plastic bags for two weeks can effectively kill lice and their eggs by depriving them of air. This method is safe and effective for items like stuffed animals, pillows, and other nonwashable items.
Choice C Reason:
The statement “Inspect any dogs or cats at home for lice” is incorrect. Lice are species-specific, meaning that the lice that infest humans do not infest pets and vice versa. Therefore, inspecting pets for lice is unnecessary when dealing with human head lice.
Choice D Reason:
The statement “Soak all combs and hairbrushes in alcohol” is partially correct but not the best option. While soaking combs and brushes in alcohol can help disinfect them, soaking them in hot water (at least 130°F) for 5-10 minutes is more effective at killing lice and their eggs. This method is safer and more commonly recommended.
