Skin color of a patient can indicate a variety of possible conditions. If blue or cyanotic skin is observed, which of the following is most likely to be causing the cyanotic skin color?
  1. The patient is under emotional distress
  2. The patient is suffering from heat exposure
  3. The patient has high blood pressure
  4. The patient has liver abnormalities
  5. The patient has inadequate breathing or heart function
Explanation
Answer: E - Blue or cyanotic skin color is indicative of a lack of oxygen reaching the body’s cells, which is ultimately the result of either poor breathing or poor heart function (or both). The lack of oxygen to cells must be resolved immediately so that permanent damage is not done to the body’s cells, especially the cells of the brain, which are extremely sensitive to a lack of oxygen or buildup of carbon dioxide.
