25. Bleeding Flashcards
the main artery that receives blood from the left ventricle and delivers it to all the other arteries that carry blood to the tissues of the body.
aorta
the smallest branches of arteries leading to the vast network of capillaries
arterioles
a blood vessel, consisting of three layers of tissue and smooth muscle, that carries blood away from the heary
artery
the small blood vessels that connect arterioles and venules; various substances pass through capillary walls, into and out of the interstitial fluid, and then on to the cells
capillaries
the formation of clots to plug openings in injured blood vessels and stop the blood flow
coagulation
a bruise from an injury that causes bleeding beneath the skin without breaking the skin
contusion
a buildup of blood beneath the skin that produces a characteristic blue or black discoloration ad the result of injury.
ecchymosis
a nose bleed
epistaxis
vomited blood
hematemesis
blood in the urine
hematuria
a hereditary condition in which the patient lacks one or more of the blood’s normal clotting factors
hemophilia
the coughing up of blood
hemoptysis
bleeding
hemorrhage
a chemical compound that slows or stops bleeding by assisting with clot formation
hemostatic agent
a condition in which the circulatory system fails to provide sufficient circulation to maintain normal cellular functions; also called shock
hypoperfusion
a condition in which low blood volume, due to massive internal or external bleeding or extensive loss of body water, results in inadequate perfusion
hypovolemic shock
black, foul smelling, tarry stool containing digested blood
melana
a life-threatening fracture of the pelvis caused by a force that displaces one or both sides of the pelvis laterally and posteriorly
open-book pelvic fracture
a device to splint the bony pelvis to reduce hemorrhage from bone ends, venous disruption, and pain
pelvis binder
the circulation of blood within an organ or tissue in adequate amounts to meet the current needs of the cells
perfusion
a condition in which the circulatory system fails to provide sufficient circulation to maintain normal cellular functions; also calledhypoperfusion
shock
the bleeding control method used when a wound continues to bleed despite the use of direct pressure; useful if a patient is bleeding severely from a partial or complete amputation
tourniquet
the narrowing of a blood vessel, such as with hypoperfusion or cold extemities
vasoconstriction
the blood vessels that carry blood from the tissues to the heart
veins
very, small, thin-walled blood vessels
venules
