5 Written questions

5 Matching questions

  1. Cause of anaphylactic shock?
  2. Medical management of neurogenic shock
  3. Causes of neurogenic shock?
  4. hydrostatic pressure
  5. Body's compensatory mechanisms for shock
  1. a Severe allergic reaction in a patient who has previously been exposed to an allergen. Ie. contrast dyes, drugs, insect bites, foods such as peanuts.
  2. b Spinal cord injury, Spinal anesthesia, depressant action of medications, lack of glucose (insulin reaction or shock), Severe pain.
  3. c the 'pushing force', pushing the fluid out of the capillaries. It's the result of the actual pressure of the fluid on the capillary walls.
  4. d Increased HR, vasoconstriction, activates renin angiotensin mechanisms, ADH increases, increase secretion of epinephrine and norepinephrine to increase BP and HR.
  5. e Stabilization of spinal cord injury, positioning spinal anesthetic patient properly, giving glucose for hypoglycemia.

5 Multiple choice questions

  1. a condition in which systemic blood pressure is inadequate to deliver oxygen and nutrients to support vital organs and cellular function- hypoxia
  2. Extremes of age, Immunosuppression, Chronic illness, Malnutrition.
  3. Vasodilation, Capillary permeability, Bronchospasm
  4. 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.
  5. DECREASED: CO, stroke volume, UO, ventricular emptying, tissue perfusion, blood pressure, LOC.
    INCREASED: HR

5 True/False questions

  1. Use of norephinephrine (Levophed) in cardiogenic shockto reverse low BP effect of nitroglycerin and morphine (MS) by elevating BP to perfuse vital organs. Causes peripheral vasoconstriction (alpha 1) and increases the force of contraction (beta 1 w/ IV fusion only). Potential to cause tachycardia.

          

  2. Sequence of events for hypovolemic shock1. Decreased circulating volume 2. decreased venous return 3. decreased stroke volume, 4. decreased CO, 5. decreased cellular oxygen supply, 6. impaired tissue perfusion,
    7. impaired cellular metabolism.

          

  3. What is neurogenic shock characterized by?Loss of sympathetic tone (disruption of SNS)
    Skin warm and dry, decreasd BP, Decreased HR, Decreased Temperature.

          

  4. Use of isoproterenol (Isuprel) in cardiogenic shokDrug 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. What is septic shock characterized by?Loss of sympathetic tone (disruption of SNS)
    Skin warm and dry, decreasd BP, Decreased HR, Decreased Temperature.
