A nurse is assessing a client who has asthma. Which of the following areas should the nurse evaluate as the most reliable indicator of central cyanosis?
A. Soles of the feet
B. Ear lobes
C. Oral mucosa
This is because central cyanosis reflects a decrease in arterial oxygen saturation and is best seen in areas where blood vessels are close to the surface, such as the oral mucosa, tongue, and lips. Peripheral cyanosis, which may be caused by vasoconstriction or poor circulation, can be seen in the soles of the feet, ear lobes, and nail beds, but it does not necessarily indicate hypoxemia.
D. Conjunctivae
