Ch.15 Shock Flash Cards

  1. define shock.
    A condition in which the circulatory system fails to provide sufficient circulation so that every body part can perform its function; also called hypoperfusion.
  2. What is an anaphylactic shock?
    Severe shock caused by an allergic reaction.
  3. What is anaphylaxis?
    An extreme, possibly life-threatening systemic allergic reaction that may include shock and respiratory failure.
  4. What is an aneurysm?
    A swelling or enlargement of a part of an artery, resulting from weakening of the arterial wall.
  5. What is the autonomic nervous system in charge of?
    The part of the nervous system that regulates functions, such as digestion and sweating, that are not controlled voluntarily.
  6. What is cardiogenic shock?
    A state in which not enough oxygen is delivered to the tissues of the body, caused by low output of blood from the heart. It can be a severe complication of a large acute myocardial infarction.
  7. What is compensated shock?
    The early stage of shock, in which the body can still compensate for blood loss.
  8. What is decompensated shock?
    The late stage of shock, when blood pressure is falling.
  9. What is edema?
    The presence of abnormally large amounts of fluid between cells in body tissues, causing swelling of the affected area.
  10. What is homeostasis?
    A balance of all systems of the body.
  11. What is hypovolemic shock?
    A condition in which low blood volume, due to massive internal or external bleeding or extensive loss of body water, results in inadequate perfusion.
  12. What is irreversible shock?
    The final stage of shock, resulting in death.
  13. What is neurogenic shock?
    Circulatory failure caused by paralysis of the nerves that control the size of the blood vessels, leading to widespread dilation; seen in spinal cord injuries.
  14. what is psychogenic shock?
    Shock caused by a sudden, temporary reduction in blood supply to the brain that causes fainting (syncope).
  15. What is septic shock?
    Shock caused by severe infection, usually a bacterial infection.
  16. what are sphincters?
    Circular muscles that encircle and, by contracting, constrict a duct, tube, or opening.
  17. What is syncope?
    Fainting spell or transient loss of consciousness.
