Question 1 of 5
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?
Correct Answer: A
Rationale: The correct answer is A: Oral mucosa. Central cyanosis is best assessed in areas with high blood flow and minimal pigmentation, such as the oral mucosa. Lips and tongue are also common sites. The oral mucosa is a reliable indicator as it reflects the oxygen saturation of arterial blood, providing a clear indication of cyanosis. Ear lobes, soles of the feet, and conjunctivae are not as reliable indicators as they may be affected by factors such as poor circulation, skin pigmentation, or exposure to external elements. Assessing central cyanosis in the oral mucosa allows for a quick and accurate evaluation of the client's oxygenation status.
