Unit 2

  1. what supplement would you give to assist wound healing
    vitamin c
  2. what do increasing neutrophils indicate
  3. what do increasing eosinophils indicate
  4. what is primary intention
    use of suture or other wound closures to approximate (place close together) the endges of an incision or clean laceration. Scar is thin and flat, risk of infection is little
  5. what is secondary intention
    left open rather than closed with sutures. pressure ulcers and abrasions are examples
  6. what is tertiary intention
    wound is contaminated, closed later b/c of increased risk for infection
  7. what is shock
    a complex clinical syndrome that may occur at any time and in any place. It is a life-threating condition often requiring team action by many health care professionals
  8. definition of shock
    failure of the circulatory system to maintain adequate perfusion of vital organs. Disorders leading to inadequate tissue perfusion result in decreased oxygenation at the cellular level. Inadequate oxygenation results in anaerobic cellular metabolism and accumulated waste products in cells. Cell and organ death can occur
  9. What is hypovolemic shock
    due to inadequate circulating blood volume (blood and plasma)
  10. what are 3 things that cause hypovolemic shock
    • hemorrhage with actual blood loss
    • burns with massive shifts of fluid due to movement of plasma proteins into interstitial spaces
    • fluid shifts or dehydration
  11. what is the most common type of shock
    hypovolemic shock
  12. what is hemorrhage
    loss of blood. Blood volume deficit of 15-25% or about 500 to 1500 mL in an adult with normal circulating blood volume is hemorrhaging. Develops when health adult loses 1/3 of the normal circulating blood (5L)
  13. what are burns
    chock occurs in people wiht large partial thickness or full thickness burns. caused by primarily a shift of plasma from vascular space into interstitial space
  14. what is adequate circulating volume dependent upon
    • heart
    • vascular tone
    • blood volume
  15. what are the stages of shock
    • nonprogressive stage - cardiac output slightly decreased, maintain BP, lactic acid increases
    • progressive stage - body begins to decompensate and the systemic circulation and microcirculation no longer work in unison, deceased circulation of reoxygenated blood (anaeorbic metabolism happens)
    • Irreversible stage - occurs if cycle or inadequate tissue perfusion is not interrupted (cellular ishemia and organ faliure and leads to death)
  16. how would you treat shock
    • get fluids in (blood and plasma)
    • put person on O2
  17. what is the earliest sign of shock
    person is irritable due to increase in epinephrine
  18. what nursing diagnosis would you assign with shock
    ineffective tissue perfusion
