Which of the following is NOT typically associated with producing stridor?

• A. Nasal congestion
• B. Airway edema
• C. Bronchoconstriction
• D. Relaxation of the vocal cords

Answer: (D)

Stridor is a high-pitched, wheezing sound resulting from turbulent airflow in the upper airway, commonly associated with conditions that lead to narrowing or obstruction of that airway. The production of stridor is typically linked with factors that create resistance or compromise the integrity of the upper respiratory passages, such as airway edema, which can occur in conditions like croup or an allergic reaction, and bronchoconstriction, which affects the lower airways but can sometimes contribute to an overall compromised respiratory function.

The relaxation of the vocal cords is not associated with stridor production. In fact, when the vocal cords are relaxed, they are positioned in a way that can actually widen the airway, allowing for proper airflow without obstruction. This state would decrease the likelihood of stridor occurring since stridor is primarily a result of narrowed or obstructed air passages, not from vocal cord relaxation. Thus, this choice of relaxation of the vocal cords stands out as the only factor that does not contribute to the production of stridor.
