- What is neurogenic shock characterized by?
- oncotic pressure
- anaphylactic shock
- hypovolemic shock
- Nursing concerns for neurogenic shock
- a vasodilation d/t ALLERGIC REACTION causing release of HISTAMINE.
- b VS, elastic compression stockings, HOB elevated 30 degrees.
- c absolute volume loss or relative volume loss as with ascites (3rd spacing) - 10-31% mortality rate.
- d Loss of sympathetic tone (disruption of SNS)
Skin warm and dry, decreasd BP, Decreased HR, Decreased Temperature.
- e also 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
5 Multiple choice questions
- 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.
- a condition in which systemic blood pressure is inadequate to deliver oxygen and nutrients to support vital organs and cellular function- hypoxia
- Increased HR, vasoconstriction, activates renin angiotensin mechanisms, ADH increases, increase secretion of epinephrine and norepinephrine to increase BP and HR.
- Severe allergic reaction in a patient who has previously been exposed to an allergen. Ie. contrast dyes, drugs, insect bites, foods such as peanuts.
5 True/False questions
Use of isoproterenol (Isuprel) in cardiogenic shok → 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
medical management of cardiogenic shock → Stabilization of spinal cord injury, positioning spinal anesthetic patient properly, giving glucose for hypoglycemia.
Use of dopamine (Intropin) in cardiogenic shock → 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
Causes of hypovolemic shock → MI, arrhythmias, valvular disease, cardiac surgery, cardiomyopathy.
distributive shock → vasodilation d/t mediators of inflammatory process in response to overwhelming INFECTION - 40-70% mortality rate depending on organism.
