A nurse is collecting data from an infant who has developmental dysplasia of the hip (DDH). Which of the following findings should the nurse expect?

A. Decreased stridor: Stridor is a high-pitched, noisy breathing sound caused by turbulent airflow through a narrowed or partially obstructed airway. In laryngotracheobronchitis, stridor is often present and may worsen with increasing airway obstruction. Therefore, decreased stridor would not be a typical finding associated with airway obstruction in this condition.

B. Increased restlessness: Increased restlessness can be a sign of worsening respiratory distress and impending airway obstruction. As the child struggles to breathe, they may become increasingly agitated and restless, indicating the need for prompt intervention to ensure adequate oxygenation.

C. Decreased heart rate: Decreased heart rate (bradycardia) is not typically associated with airway obstruction in laryngotracheobronchitis. In fact, the heart rate may increase as a compensatory response to hypoxia and respiratory distress.

D. Decreased temperature: Changes in temperature are not typically associated with airway obstruction in laryngotracheobronchitis. The focus of monitoring in this condition is primarily on respiratory distress and signs of worsening airway obstruction.

A. "Has your son had a sore throat recently?"

This question is relevant because acute rheumatic fever often occurs as a complication of untreated or inadequately treated streptococcal throat infection (strep throat). A recent history of sore throat could indicate a preceding streptococcal infection, which is an important predisposing factor for the development of acute rheumatic fever.

B. "Was your son born with this cardiac defect?"

This question is less relevant in the context of acute rheumatic fever. Acute rheumatic fever is not a congenital heart defect; it is an inflammatory condition that affects the heart valves following streptococcal infection. While it's important to assess the child's cardiac health, asking about congenital heart defects may not directly relate to the current condition.

C. "Are you aware that your son will have to be in isolation?"

This question is not applicable to acute rheumatic fever. Acute rheumatic fever is not a contagious condition that requires isolation. It is an autoimmune response triggered by streptococcal infection and does not pose a risk of transmission to others.

D. "Has your child had any injuries recently?"

Inquiring about recent injuries is not directly related to acute rheumatic fever. Acute rheumatic fever is an inflammatory condition primarily triggered by streptococcal infection and is not caused by physical injuries.
