While assessing your patient you see a bluish discoloration of the skin caused by hemoglobin deprived of oxygen. Which of the following terms best describes this skin condition?

Anoxic erythema
Cyanosis
Ecchymosis

Explanation

Answer: B - Cyanosis is the bluish discoloration of the skin caused by oxygen-deprived hemoglobin. Oxygen gives blood its red color and when patients become hypoxic they will begin to show cyanosis in the lips, face and extremities. Mottling is the spotting seen on the trunk of a patient with poor circulation and ecchymosis is a medical term for bruising.
