NUR 434 Exam 3 Shock States Written
Exam 2025-2026 Questions And
Answers Graded A+
what is cardiogenic shock - ✔ANASWER✔-Occurs when the heart
itself/pump fails and unable to supply sufficient blood to the body
what is shock - ✔ANASWER✔-a critical condition where the body
has decreased tissue perfusion and there is an imbalance of
oxygen supply and demand (oxygen demand significantly
outweighs supply)
what are the 5 steps of shock - ✔ANASWER✔-1. state of
hypoperfusion/hypotension
2. oxygen does not get to the tissue which causes hypoxia
,3. cells do not function properly and shift into an anaerobic
metabolism
4. anaerobic metabolism produces lactate which leads to
metabolic acidosis
5. organs start to fail
what are the 4 types of shock - ✔ANASWER✔-Cardiogenic
Hypovolemic
Distributive: septic, neurogenic, anaphylactic
Obstructive
what 4 things cause cardiogenic shock - ✔ANASWER✔-1. MI
2. Valve problem
3. Dysrhythmias
4. Cardiomyopathy
what is hypovolemic shock - ✔ANASWER✔-loss of too much
blood/fluid in the body
what causes hypovolemic shock - ✔ANASWER✔-bleeding
vomiting
diarrhea
,burns
polyuria
3rd spacing
what is distributive shock - ✔ANASWER✔-Shock due to
widespread vasodilation causing relative hypovolemia
what is obstructive shock - ✔ANASWER✔-obstruction of blood
flow
what shock is it when there is a problem with the gas pump itself -
✔ANASWER✔-cardiogenic shock
what shock is it when there's no gas in the pump - ✔ANASWER✔-
hypovolemic
what shock is it when there's something blocking gas from
coming out - ✔ANASWER✔-obstructive
what shock is it when there's a problem with the hose (hole or it's
too big) - ✔ANASWER✔-distributive
, what are 7 things you should assess for shock - ✔ANASWER✔-1.
HR
2. respiratory rate and effort
3. blood pressure
4. hemodynamics
5. mentation
6. urine output
7. skin signs
what are the 4 goals for treating all types of shock -
✔ANASWER✔-1. optimize oxygen delivery
2. minimize oxygen consumption
3. identify and treat the underlying cause
4. effective management of shock (good vital signs and good
perfusion)
how can optimize oxygen delivery with shock - ✔ANASWER✔--
provide supplemental oxygen
-intubation/mechanical ventilation
-restore volume
