Which term describes abnormal blue discoloration due to poor circulation or inadequate oxygenation of the blood?

• A. Acute
• B. Cardiomegaly
• C. Cystocentesis
• D. Cyanosis/Cyanotic

Answer: (D)

Cyanosis is the term for abnormal blue discoloration of mucous membranes and skin that occurs when circulating blood has too little oxygen or perfusion is poor. It reflects increased deoxygenated hemoglobin in capillary blood, usually when arterial oxygen saturation falls or circulation is inadequate. Central cyanosis involves the tongue and lips and points to a systemic oxygenation problem, while peripheral cyanosis stems from reduced blood flow to a limb. The other terms don’t describe color changes or oxygenation: acute denotes sudden onset or short duration, cardiomegaly means an enlarged heart, and cystocentesis is a urine collection procedure. Recognizing cyanosis helps guide urgent evaluation and treatment of underlying hypoxemia or poor circulation.
