NURS 502 EXAM 3| ACTUAL QUESTIONS & CORRECT
VERIFIED ANSWERS 2025
1. Shock ANS >> A diverse group of life-threatening conditions
2. what is the common factor among all types of shock? ANS >> impaired
oxygen utilization by cells
-decrease perfusion (hypoperfusion) to your tissues, therefore they are not getting
enough oxygen=cell damage, leading to organ failure
3. what are causes of inadequate cellular oxygenation? ANS >> 1. decreased
cardiac output
2. maldistribution of blood flow (blood can still be in the body, but it is not going back
to the heart)
3. reduced blood oxygen content
4. T/F ANS >> (related to shock) The cardiovascular system fails to perfuse the
tissues adequately resulting in widespread impairment of cellular
metabolism. ANS >> True!
Metabolism ANS >> meaning all the chemical tasks of maintaining essential cellular
func- tions
5. impaired tissue perfusion results from many causes that alter? ANS >> 1.
cardiac function (heart not working)
2. blood volume
3. blood pressure (decrease)

, 6. because there is a decrease in tissue perfusion that impairs cellular metab-
olism in shock what does that mean? ANS >> -impaired oxygen use
-impaired glucose use
-impaired energy production! (glycolysis, citric acid cycle (Kreb's), oxidative phos-
phorylation (electron transport chain))
because of this, no ATP=no pumps working!
7. if cells do not have enough oxygen then they are going to shift from? ANS
>> aer- obic to anaerobic metabolism! because of this ANS >>
-lactic acid is a byproduct
-decrease amounts of ATP, disrupting the Na+/K+ pump leading Na+ to move
INSIDE the cell and K+ to move OUTSIDE the cell=hyperkalemia
-because Na+ moves inside the cell, water will follow so the cells will swell leading
to ruptures=decrease vascular volume
-hyperkalemia=cardiac arrhythmias/nervous system disturbances
8. shock also impairs? ANS >>
glucose! because ANS >>
1. there is inadequate glucose delivered to the cells
