SULLIVAN Flashcards
Bluish-gray discoloration of the skin and mucous membrane
cyanosis
caused by hypoxia and results in color changes in the central aspects of the body and mucous membranes; associated with disease of the cardiovascular or pulmonary system
central cyanosis
caused by hypoxia with color changes in the nail beds and lips associated with decreased cardiac output and exposure to cold (extreme vasoconstriction)
peripheral cyanosis
caused by bruising or bleeding under the skin and may be seen anywhere on the body; new bruises appear bluish-purple while older bruises are greenish-yellow; often caused by trauma (e.g., falls, sports injury, physical abuse) patients on blood thinning agents (e.g., coumadin) tend to bruise more easily
ecchymosis
reddened area of skin caused by increased blood flow (hyperemia); associated with skin irritation or injury, infection, and inflammation; redness over a bony prominence warns of the potential development of the cubitus ulcer
erythema
diffuse redness of face; may involve other areas; related to emotions (embarrassment, anger), physical exertion, fever, and increase temperature of environment
flushing
caused by impaired liver function (e.g., hepatitis, liver cancer), the skin takes on a yellow-orange hue; it is best observed in the sclera, mucous membranes, and the palms of hand and sole of the feet
Jaundice
the skin takes on a lighter tone (more white with decreased pink hue) than normal for the individual (a normally “fair” skin color should be ruled out); for darker skin, palor is apparent by loss of red tones; associated with anemia and impaired circulation; observed in the face palms mucous membranes and nail beds
Pallor (pale)
tiny red or purple hemorrhagic spots caused by capillary bleeding with subsequent leakage of blood into the skin; tend to appear in clusters and often seen on the ankles and feet but can only occur anywhere on the body; maybe a sign of thrombocytopenia (low platelet count); as platelets play a critical role in clotting, reduce counts impair clothing and increase the risk of bleeding; low platelet counts are associated with the variety of medication and disorders
petechiae
tiny red or purple hemorrhagic spots caused by capillary bleeding with subsequent leakage of blood into the skin; tend to appear in clusters and often seen on the ankles and feet but can only occur anywhere on the body; maybe a sign of thrombocytopenia (low platelet count); as platelets play a critical role in clotting, reduce counts impair clothing and increase the risk of bleeding; low platelet counts are associated with the variety of medication and disorders
