5 Written questions

5 Matching questions

  1. 3 requirements for adequate blood flow
  2. Use of dobutamine (Dobutrex) in cardiogenic shock
  3. symptoms of shock
  4. S/s of hypodynamic/cold phase of septic shock?
  5. What is cardiogenic shock characterized by?
  1. a mental confusion, depression, apathy, oliguria, heart failure (low CO), tachycardia (report HR >100/min), thready pulse, thirst, restlessness, anxiety, lethargy, cool extremities, pale skin, frequently hypotension (report BP <90), fainting, syncope rapid, shallow breathing (body trying to get more O2), metabolic acidosis, coma.
  2. b Further increased HR; Further decreased BP; Increased pulse; decreased CO; cool, mottled skin; further increased respirations;
    decreased urine output; Decreased temperature/subnormal, low WBC count with many immature cells.
  3. c Adequate cardiac pump
    Effective vasculature
    Sufficient blood volume
  4. d Drug of choice for cardiogenic shock because does not cause vasoconstriction but increases strength of contractions, improves stroke volume and CO. Minimal increase in HR. has a half-life of 2 minutes, given as an IV infusion drip, dosed in mcg/kg/min. only give in the ICU
  5. e DECREASED: CO, stroke volume, UO, ventricular emptying, tissue perfusion, blood pressure, LOC.
    INCREASED: HR

5 Multiple choice questions

  1. Extremes of age, Immunosuppression, Chronic illness, Malnutrition.
  2. Remove causitive agent.
    Order of TX:
    Epi IV to provide vasoconsrictive action and bronchodilation
    Diphenhydramine (Benadryl) IV to reverse histamine effectsa
    Nebulized albuterol (Proventil) to reverse histamine-induced bronchospasm.
    Oral steroid such as methylprednisolone (Solumedrol) for longer lasting antiinflammatory effects.
  3. MASSIVE VASODILATION resulting in relative hypovolemia (3 divisions: anaphylactic, neurogenic, septic)
  4. monitor HR, BP, LOC, urine output. Recognize early and manage to reduce chance of end-stage organ damage. Provide pt teaching regarding drug therapy.
  5. vital signs, electrolyte imbalance, I&O, correct acidosis

5 True/False questions

  1. septic shockvasodilation d/t mediators of inflammatory process in response to overwhelming INFECTION - 40-70% mortality rate depending on organism.

          

  2. oncotic pressurealso called 'colloid osmotic pressure', is the 'pulling force', pulling fluids from the surrounding tissue into the capillaries. It's the result of a difference in the concentration of solutes in the fluid inside the capillaries as opposed to outside them

          

  3. S/S of hyperdynamic/warm phase of septic shock?Increased HR and pulse, Decreased BP; flushed skin; Increased respirations/hyperventilation; Restlessness and confusion; increased urine output; Increased temperature. Legs may feel cool and mottled.

          

  4. 3 organs most concerned about with shockmonitor HR, BP, LOC, urine output. Recognize early and manage to reduce chance of end-stage organ damage. Provide pt teaching regarding drug therapy.

          

  5. What is anaphylactic shock characterized by?Vasodilation, Capillary permeability, Bronchospasm
