A nurse is caring for a child who has red marks across his cheeks. Which of the following actions should the nurse take?

Choice A reason: The onset of low blood glucose, or hypoglycemia, usually occurs rapidly and can be triggered by skipping meals, exercising too much, or taking too much insulin. The nurse should teach the parents to recognize the signs and symptoms of hypoglycemia and how to treat it promptly.

Choice B reason: Feeling shaky is one of the common signs of low blood glucose, along with hunger, sweating, dizziness, confusion, and irritability. The nurse should teach the parents to check the child's blood glucose level and give him a fast-acting carbohydrate, such as juice, candy, or glucose tablets, if it is below 70 mg/dL.

Choice C reason: Sweating can occur with low blood glucose, not high blood glucose, or hyperglycemia. Hyperglycemia can cause symptoms such as thirst, frequent urination, dry mouth, blurred vision, and fatigue. The nurse should teach the parents to monitor the child's blood glucose level regularly and adjust his insulin dose, diet, and exercise accordingly.

Choice D reason: Nausea and vomiting can occur with high blood glucose, especially if it leads to diabetic ketoacidosis, a serious complication of diabetes. Diabetic ketoacidosis can also cause abdominal pain, fruity breath, rapid breathing, and coma. The nurse should teach the parents to seek emergency medical attention if the child has these symptoms.

Choice A reason: Improved hydration is not a specific indicator of the effectiveness of the treatment for acute laryngotracheobronchitis. Hydration status should be monitored for any child with a respiratory infection, but it does not reflect the severity of the airway inflammation.

Choice B reason: Decreased temperature is not a specific indicator of the effectiveness of the treatment for acute laryngotracheobronchitis. Fever may or may not be present in this condition, and it does not correlate with the degree of airway obstruction.

Choice C reason: Decreased stridor is a specific indicator of the effectiveness of the treatment for acute laryngotracheobronchitis. Stridor is a high-pitched sound caused by turbulent airflow through a narrowed upper airway. It indicates a significant obstruction that can compromise breathing. A reduction in stridor means that the airway inflammation has subsided and the child can breathe more easily.

Choice D reason: Barking cough is not a specific indicator of the effectiveness of the treatment for acute laryngotracheobronchitis. Barking cough is a characteristic symptom of this condition, caused by the swelling of the vocal cords. It may persist for several days after the acute episode, even when the child is improving.
