What sign indicates inadequate breathing in a patient?

• A. Rapid heartbeat
• B. Cyanosis (bluish coloration of the skin)
• C. Dry mouth
• D. Increased sweating

Answer: (B)

Cyanosis is a critical sign that indicates inadequate breathing in a patient. It manifests as a bluish coloration of the skin, particularly noticeable on the lips, fingertips, and other extremities. This discoloration occurs when there is a lack of oxygen in the blood, which can result from various respiratory issues such as airway obstruction, severe asthma, or pneumonia. When oxygen levels drop significantly, hemoglobin that normally appears red becomes darker and produces a bluish tint, signaling that the body's tissues are not receiving enough oxygen. Recognizing cyanosis is vital as it often prompts immediate medical intervention to address the underlying cause of inadequate breathing and restore normal oxygenation. This sign is clinically significant and can be a direct indicator of respiratory distress or failure, necessitating quick assessment and action.
