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 D
Explanation
Choice A: Nausea and vomiting are not common signs of hypoglycemia, which is a low blood glucose level. Nausea and vomiting are more likely to occur with hyperglycemia, which is a high blood glucose level, or with diabetic ketoacidosis, which is a life-threatening complication of diabetes.
Choice B: Sweating is not a common sign of hyperglycemia, but rather a sign of hypoglycemia. Sweating occurs as a result of the activation of the sympathetic nervous system, which tries to raise the blood glucose level by releasing adrenaline and other hormones.
Choice C: The onset of low blood glucose usually occurs quickly, not slowly. Low blood glucose can be caused by taking too much insulin, skipping meals, exercising too much, or drinking alcohol. Low blood glucose can lead to confusion, seizures, coma, or death if not treated promptly.
Choice D: Feeling shaky is a common sign of hypoglycemia, as the body tries to cope with the lack of glucose as an energy source. Feeling shaky can also be accompanied by other signs such as hunger, nervousness, dizziness, or weakness.

Correct Answer is C
Explanation
Choice A: A popping sensation when swallowing is not a sign of a tympanic membrane rupture, as it is a normal phenomenon that occurs when the eustachian tube opens and closes to equalize the pressure between the middle ear and the atmosphere. A popping sensation when swallowing may be associated with otitis media with effusion, which is a condition that causes fluid accumulation behind the eardrum, but it does not indicate a rupture.
Choice B: Green-blue discharge could be indicative of infection but is not as directly related to the rupture event as the sudden pain relief is.
Choice C: The correct answer is sudden relief of pain. This is because the rupture of the tympanic membrane releases the pressure and fluid that has built up in the middle ear, leading to an immediate decrease in pain.
Choice D: An increased temperature is not a sign of a tympanic membrane rupture, as it is a nonspecific symptom that may indicate various conditions, such as inflammation, infection, or fever. An increased temperature may be associated with otitis media with effusion, which is a condition that causes fluid accumulation behind the eardrum, but it does not indicate a rupture.
