Which of the following is a common sign of respiratory distress?

A common sign of respiratory distress is a change in skin color, particularly a bluish tint to the skin, known as cyanosis. This condition occurs when there is inadequate oxygen in the blood or when respiratory function is compromised, indicating that the body is not receiving enough oxygen. Changes in skin color are often one of the most visible and significant indicators of respiratory distress that warrant prompt assessment and intervention.

Other signs may include labored breathing, use of accessory muscles, and altered mental status, which can help emergency responders recognize the severity of the situation. While a rapid pulse can sometimes be seen in cases of respiratory distress due to increased demand for oxygen, it can also be influenced by other factors unrelated to respiratory issues. Bradycardia, or a slow heart rate, is typically not associated with respiratory distress and may indicate other conditions.

Therefore, recognizing a change in skin color is a more direct and specific sign of respiratory distress, making it a critical indicator in emergency situations.
