NR 464 EXAM 3 QUESTIONS WITH 100%
VERIFIED ANSWERS!!
If SvO2 decreases, it indicates that tissues are extracting a __________ percentage of
oxygen from the blood
higher
What electrolytes to monitor in cardiogenic shock?
K+, Na+, Mg+
Overall goal of care of cardiogenic shock?
Restore blood flow to myocardium by restoring the balance between O2 supply and demand
Specific measures to restore blood flow in cardiogenic shock?
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?
-Diuretics (reduces preload)
-Vasodilators (reduces afterload)
-Inotropic drug (i.e. dopamine)
-Antidysrhythmics
-Norepinephrine, perhaps
-fluid and salt restriction
Relative hypovolemia
-When fluid moves out of vasculature into extravascular space ("third spacing")
Goal of treatment for hypovolemic shock?
, -Determine underlying cause
-Stopping fluid loss and restoring volume
-Risk of fluid overload
-Start with isotonic saline
Anaphylactic shock physiologic effects
-Massive vasodilation
-Release of mediators (bradykinins, etc.)
-Increased capillary permeability
Anaphylactic shock clinical manifestations
-Anxiety, confusion, dizziness
-Sense of impending doom
-Chest pain
-Incontinence
-Angioedema
-Wheezing, stridor
-Flushing, pruritus
-Respiratory distress/circulatory fx
Anaphylactic shock collaborative care?
-Epinephrine priority drug
-Maintain patent airway (nebulized bronchodilators, intubate if necessary)
-IV fluids
-Document allergies
-Patient position similar to hypovolemia)
anaphylactic shock, how do we treat the decreased BP if fluids fail?
steroids!
vasopressors
SIRS acronym?
