The text ties explanation to calm, making the correct, supportive action.

Correct Answer: A

Rationale: Cyanosis' occurs with low blood oxygen, per ProProfs. Blue tint e.g., lips, 90% SpOâ‚‚ reflects deoxygenated blood e.g., 20% darker unlike 'jaundice' , yellow e.g., liver issue. 'Paleness' is blood loss e.g., not oxygen. 'Flushing' is heat e.g., opposite. A nurse spots e.g., Blue fingertips' per respiratory link, a physiological sign.
