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?
Barking cough
Decreased stridor
Improved hydration
Decreased temperature
The Correct Answer is B
Choice A: A barking cough is not a finding that indicates that the treatment has been effective, but rather a symptom of acute laryngotracheobronchitis, which is also known as croup. Croup is a condition that causes inflammation and narrowing of the upper airway and produces a characteristic barking or seal-like cough. A barking cough may persist for several days after the onset of croup and does not reflect the severity of the airway obstruction.
Choice B: Decreased stridor is a finding that indicates that the treatment has been effective, as stridor is a sign of airway obstruction caused by acute laryngotracheobronchitis. Stridor is a high-pitched, noisy breathing sound that occurs when the air passes through the narrowed airway. Stridor may be inspiratory, expiratory, or biphasic,
depending on the level of obstruction. Decreased stridor means that the airway is less obstructed and the child can breathe more easily.
Choice C: Improved hydration is not a finding that indicates that the treatment has been effective, but rather a goal of treatment for acute laryngotracheobronchitis. Dehydration can worsen the symptoms and complications of croup by thickening the mucus and increasing the risk of infection. Improved hydration can help thin out the mucus and prevent dehydration. Hydration can be improved by encouraging oral fluids, administering intravenous fluids, or providing humidified air.
Choice D: Decreased temperature is not a finding that indicates that the treatment has been effective, but rather a possible outcome of treatment for acute laryngotracheobronchitis. Fever may or may not be present in croup, depending on the cause and severity of the condition. Fever can be caused by viral or bacterial infection, inflammation, or dehydration. Decreased temperature can indicate that the infection or inflammation is resolving or that the dehydration is corrected.

Correct Answer is B
Explanation
Choice A: A 3-year-old child is not developmentally ready to descend stairs by placing both feet on each step and holding on to the railing. A 3-year-old child can walk up stairs alternating feet with one hand held by an adult or on the railing. A 3-year-old child can also walk down stairs placing both feet on each step with one hand held by an adult.
Choice B: A 4-year-old child is developmentally able to descend stairs by placing both feet on each step and holding on to the railing. A 4-year-old child can also walk up stairs alternating feet without assistance.
Choice C: A 5-year-old child is developmentally more advanced than descending stairs by placing both feet on each step and holding on to the railing. A 5-year-old child can walk up and down stairs alternating feet without assistance.
Choice D: A 6-year-old child is developmentally more advanced than descending stairs by placing both feet on each step and holding on to the railing. A 6-year-old child can walk up and down stairs alternating feet without assistance and can also hop and skip on one foot.
Correct Answer is C
Explanation
Choice A: This statement indicates a lack of understanding of the teaching, as insulin should not be stored in the freezer, as freezing can damage the insulin and make it ineffective. Insulin should be stored in a cool and dry place, away from direct sunlight and heat sources. Unopened bottles of insulin can be stored in the refrigerator until their expiration date, but opened bottles of insulin can be kept at room temperature for up to 28 days.
Choice B: This statement indicates a lack of understanding of the teaching, as the morning blood glucose level for a child who has type 1 diabetes mellitus should be between 70 and 110 mg/dL, according to the American Diabetes Association. A blood glucose level between 90 and 130 mg/dL may indicate hyperglycemia, which is high blood sugar and can cause symptoms such as thirst, hunger, fatigue, or frequent urination. A blood glucose level below 70 mg/dL may indicate hypoglycemia, which is low blood sugar and can cause symptoms such as sweating, shaking, dizziness, or confusion.
Choice C: This statement indicates an understanding of the teaching, as eating a snack half an hour before playing soccer can help prevent hypoglycemia, which is low blood sugar, in a child who has type 1 diabetes mellitus. Physical activity can lower blood sugar levels by increasing the uptake of glucose by the muscles. Eating a snack that contains carbohydrates and protein can provide energy and prevent a sudden drop in blood sugar levels during or after exercise.
Choice D: This statement indicates a lack of understanding of the teaching, as regular insulin should not be skipped or stopped when a child who has type 1 diabetes mellitus is sick. In fact, insulin may need to be increased or adjusted when a child is sick, as illness can raise blood sugar levels by causing stress hormones or inflammation. The child should monitor their blood sugar levels more frequently when they are sick and follow their sick day plan that includes taking insulin, checking for ketones, staying hydrated, and contacting their provider if needed.
