Stridor in a pediatric patient indicates potential what?

• A. Dehydration
• B. Nasal congestion
• C. Gastroesophageal reflux
• D. Airway obstruction

Answer: (D)

Stridor is a high-pitched, musical sound heard with breathing that indicates partial obstruction of the upper airway. In children, the airway is small, so even slight swelling or blockage can produce this sound, pointing to an airway narrowing above the chest. This is different from sounds like wheeze, which come from lower in the airway, so stridor specifically flags airway obstruction. Dehydration doesn’t create an audible stridor; it affects fluids and mucous membranes but not the upper airway soundtrack. Nasal congestion can cause noisy breathing, but the sound is not the same high-pitched stridor and it doesn't reflect a true airway blockage. Gastroesophageal reflux can cause coughing or irritant symptoms, but it doesn’t typically present as stridor. So, stridor signals potential airway obstruction and prompts prompt assessment of airway patency and possible causes such as swelling, foreign body, or infection affecting the upper airway.
