5 Matching Questions
- Two symptoms common to all types of shock?
- What is neurogenic shock characterized by?
- Sequence of events for hypovolemic shock
- Body's compensatory mechanisms for shock
- a 1. 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.
- b Increased HR, vasoconstriction, activates renin angiotensin mechanisms, ADH increases, increase secretion of epinephrine and norepinephrine to increase BP and HR.
- c Loss of sympathetic tone (disruption of SNS)
Skin warm and dry, decreasd BP, Decreased HR, Decreased Temperature.
- d a condition in which systemic blood pressure is inadequate to deliver oxygen and nutrients to support vital organs and cellular function- hypoxia
- e mental confusion and oliguria
5 Multiple Choice Questions
- Vasodilation, Capillary permeability, Bronchospasm
- vasodilation d/t nerve injury and suppression of SNS.
- MI, arrhythmias, valvular disease, cardiac surgery, cardiomyopathy.
- 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.
- to 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.
5 True/False Questions
exsanguination → vasodilation d/t mediators of inflammatory process in response to overwhelming INFECTION - 40-70% mortality rate depending on organism.
Nursing considerations for hypovolemic shock → I&O, VS (especially temp), labs.
distributive shock → MASSIVE VASODILATION resulting in relative hypovolemia (3 divisions: anaphylactic, neurogenic, septic)
S/S of hyperdynamic/warm phase of septic shock? → 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.
septic shock → vasodilation d/t mediators of inflammatory process in response to overwhelming INFECTION - 40-70% mortality rate depending on organism.
