Which term refers to bluish discoloration due to poor oxygenation?

• A. Artery
• B. Cardiomegaly
• C. Cyanosis/Cyanotic
• D. Benign

Answer: (C)

Bluish discoloration from poor oxygenation is cyanosis. It happens when hemoglobin in the blood is carrying less oxygen, so capillaries appear blue or purplish, especially on mucous membranes like the gums, lips, or tongue. This sign points to hypoxemia and needs prompt assessment and oxygenation, with attention to the underlying cause. Peripheral cyanosis can occur with cold or reduced blood flow, but central cyanosis reflects systemic oxygen shortage. The other terms listed don’t describe this color change related to oxygen levels.
