EXAM QUESTIONS| 100% SOLVED!!
Shock - (ANSWER)Inadequate tissue perfusion that impairs maintenance of
normal cellular metabolism
-If you're in shock you switch to anaerobic metabolism
4 types of shock - (ANSWER)Cardiogenic
Hypovolemic
Distributive-blood in body, but not in vascular
Obstructive- like with tourniquet
Urine output for shock - high or low? (generally) - (ANSWER)low
Initial stage of shock - (ANSWER)-Evidence of inadequate tissue perfusion
-Lactic acidosis starts
Compensatory stage of shock - (ANSWER)Aldosterone, Renin, ADH, Angiotensin
are all released
4 stages of shock - (ANSWER)Initial
Compensatory
Progressive
,Refractory
Progressive stage - (ANSWER)Will now be hypotensie
MODS has started
Refractory stage of shock - (ANSWER)End organ damage
Survival is unlikely
Definitely not keeping your kidneys
Trauma Triad of Death - (ANSWER)1. Coagulopathy
2. Hypothermia
3. Metabolic Acidosis
Cardiogenic shock causes - (ANSWER)-MI
-Cardiomyopathy
-Pulmonary hypertension
-Cardiac tamponade
If SvO2 decreases, it indicates that tissues are extracting a __________
percentage of oxygen from the blood - (ANSWER)higher
What electrolytes to monitor in cardiogenic shock? - (ANSWER)K+, Na+, Mg+
, Overall goal of care of cardiogenic shock? - (ANSWER)Restore blood flow to
myocardium by restoring the balance between )2 supply and demand
Specific measures to restore blood flow in cardiogenic shock? - (ANSWER)Cardiac
catheterization ASAP
Angioplasty with stenting, emergency revascularization, valve replacement
*until these interventions performed, heart must be supported to optimize stroke
volume and CO*
Drug therapy for cardiogenic shock? - (ANSWER)-Diuretics (reduces preload)
-Vasodilators (reduces afterload)
-Inotropic drug (i.e. dopamine)
-Antidysrhythmics
-Norepinephrine, perhaps
-*fluid and salt restriction*
Relative hypovolemia - (ANSWER)-When fluid moves out of vasculature into
extravascular space ("third spacing")
Goal of treatment for hypovolemic shock? - (ANSWER)-Determine underlying
cause
-Stopping fluid loss and restoring volume
