ATCN 2020 CHAPTER 3 SHOCK EXAM 2025
QUESTIONS AND VERIFIED SOLUTIONS|
ABSOLUTE SUCCESS GUARANTEED.
The most effective method of restoring adequate cardiac output, end organ
perfusion, and tissue oxygenation is to: - correct answer - Restore venous
return to normal by locating and stopping the source of bleeding. Volume
repletion will allow recovery from the shock state only when the bleeding
has stopped.
At the cellular level, inadequately perfused and poorly oxygenated cells
shift from ______________________________ to
_________________________________ resulting in the formation of rising
lactic acid levels and the development of metabolic acidosis. - correct
answer - At the cellular level, inadequately perfused and poorly oxygenated
cells shift from aerobic metabolism to anaerobic metabolism resulting in the
formation of rising lactic acid levels and the development of metabolic
acidosis.
____________________________________________________________
_________________ are the goals of treating hemorrhagic shock. - correct
answer - Definitive control of hemorrhage and restoration of adequate
circulating volume are the goals of treating hemorrhagic shock.
Most injured patients who are in hemorrhagic shock require: - correct
answer - Early surgical intervention or agioembolization to reverse the
shock state.
, Page |2
Define Profound Circulatory Shock - correct answer - As evidence by
hemodynamic collapse with inadequate perfusion of the skin, kidneys, and
central nervous system is simple to recognize.
Compensatory mechanisms can prevent a measurable fall in systolic
pressure up to 30% of the patients blood volume is lost.
Tachycardia is defined as?
Infant
Child
Adult - correct answer - Infant. - Heart rate > 160
Child. - heart rate > 140
Adult. - heart rate > 100
A narrowed pulse pressure suggests ? - correct answer - A significant
blood loss.
Massive blood loss may produce only a slight decrease in
____________________________________________________
concentration. - correct answer - Massive blood loss may produce only a
slight decrease in initial hematocrit and hemoglobin concentration. Thus a
very low Hct or Hgb may suggest massive blood loss or chronic anemia.
, Page |3
____________________________ and / or
___________________________ levels can be useful in determining the
presence and severity of shock. - correct answer - Base deficit and / or
Lactate levels can be useful in determining the presence and severity of
shock.
Define hemorrhage - correct answer - Is an acute loss of circulating blood
volume. Normal adult blood volume is approximately 7% of body weight.
(70kg male has a circulation volume of 5 liters.)
The blood volume of an obese patient is based on ???? - correct answer -
Ideal body weight
What is the first step in managing shock in trauma patients? - correct
answer - The first step in managing shock in trauma patients is to
recognize it.
Define Shock - correct answer - An abnormality of the circulatory system
that results in inadequate oxygen perfusion and tissue oxygenation.
List the second step in managing shock - correct answer - Is to identify the
probable cause of shock and adjust treatment accordingly.
