Which of the following is considered a late sign of respiratory distress?

• A. Coughing
• B. Cyanosis
• C. Wheezing
• D. Chest retractions

Answer: (B)

Cyanosis is a late sign of respiratory distress because it indicates that the body is not receiving enough oxygen, leading to a bluish discoloration of the skin, particularly around the lips and extremities. This sign typically appears when respiratory distress has progressed significantly and is a signal of potentially serious hypoxia. In contrast, coughing, wheezing, and chest retractions are considered earlier indicators of respiratory distress. Coughing may indicate the presence of irritation in the airway or lungs, wheezing suggests constriction of the airways, and chest retractions are a sign that the muscles of respiration are having to work harder due to increased effort needed to breathe. Recognizing cyanosis as a late manifestation can help healthcare providers prioritize timely interventions.
