ANSWER

ANS: 4
Central cyanosis is observed in the tongue, soft palate, and conjunctiva of the eye, where blood flow is high. Central cyanosis indicates hypoxemia. Peripheral cyanosis seen in the palms and soles of the feet, nail beds, or earlobes is often a result of vasoconstriction and stagnant blood flow.
