Exam Actual Questions and Answers
2026
___ is defined as inadequate tissue perfusion, resulting from
insufficient oxygen delivery, uptake and utilization to meet the
metabolic demands of cells and organs. -
correct answer ✅Shock
Shock i s a dynamic process that begins when cells are ___. -
correct answer ✅Hypoperfused
If shock goes unrecognized and untreated, the hypoperfused cells
shift from aerobic to anaerobic metabolism, which leads to life
threatening ___. -
correct answer ✅Acidosis, Tissue Ischemia, and Cellular Death
when coupled with the incomplete removal of metabolic waste
products.
Inadequate compensation leads to ___. -
correct answer ✅Shock
Circulation in the human body is a closed system consisting of ___. -
correct answer ✅The pump (heart)
The pipes (vasculature)

Circulating fluid (intravascular blood volume)
What are the 4 categories of shock? -
correct answer ✅Hypovolemic
Obstructive
Cardiogenic
Distributive
___ from hemorrhage is the leading cause of preventable deaths in
trauma patients. -
correct answer ✅Hypovolemic Shock
___ is caused by a decrease in the amount of circulating blood
volume or a loss of plasma from the intravascular space. -
correct answer ✅Hypovolemia
Burn trauma can result in hypovolemic shock from damage to the
cell membranes, leading to ___. -
correct answer ✅Plasma and protein leakage

Exam Actual Questions and Answers
2026
In hypovolemic shock, decreased circulating volume results in ___. -
correct answer ✅Decreased preload
Decreased preload means decreased ___. -
correct answer ✅Cardiac Output
Goal-directed therapy for hypovolemic shock is aimed at ___. -
correct answer ✅Replacing the type of volume the patient has
lost in order to restore physiologic homeostasis (electrolytes with
precipitous nonhemorrhagic losses or blood products with blood
loss).
___ results from hypo-perfusion of the tissue due to an obstruction
in either the vasculature or heart. -
correct answer ✅Obstructive Shock
What are two classic examples of obstructive shock that result from
trauma? -
correct answer ✅Cardiac tamponade
Tension pneumothorax

Exam Actual Questions and Answers
2026
With ___, the increase in intrathoracic pressure leads to
displacement of the vena cava, obstruction to atrial filling,
decreased preload and decreased cardiac output. -
correct answer ✅Tension pneumothorax
With ___, an accumulation of fluid within the inflexible pericardial
sac impedes diastolic expansion and filling, which in turn, leads to a
decrease in preload, stroke volume, cardiac output, and ultimately
end-organ perfusion. -
correct answer ✅Cardiac tamponade
Obstructive shock can also occur on the right side of the heart
during systole caused by ___. -
correct answer ✅Venous air embolism in the pulmonary artery
___ is a common iatrogenic cause of increased intrathoracic
pressure resulting in compression of the heart and decreased
cardiac output. -
correct answer ✅Hyperventilation
