ATCN 2020 CHAPTER 3 SHOCK EXAM
WITH CORRECT ACTUAL QUESTIONS AND
CORRECTLY WELL DEFINED ANSWERS
LATEST ALREADY GRADED A+ 2026
Pregnancy - Physiological changes - ANSWERS-The normal
hypervolemia that occurs with pregnancy means that it
takes a greater amount of blood loss to manifest perfusion
abnormalities in the mother, which may also be reflected in
decreased fetal perfusion.
________________________________________________ is
the most common complication or hemorrhagic shock. -
ANSWERS-Inadequate volume replacement is the most
common complication of hemorrhagic shock.
An ________________________________ is the most
common cause of poor response to fluid therapy. -
ANSWERS-An undiagnosed source of bleeding is the most
common cause of poor response to fluid therapy.
,Lethal Triad of Death - ANSWERS-Coagulopathy
Hypothermia
Acidosis
The Blood volume for a child is calculated as - ANSWERS-8%
to 9% of body weight. (70 - 80 ml/kg)
Class I Hemorrhage - defined - ANSWERS-is exemplified by
the condition of an individual who has donated a unit of
blood.
< 15% Blood Volume Loss
Minimal Tachycardia
No measurable changes in blood pressure
No measurable changes in pulse pressure
No measurable changes in respiratory rate
Compensatory mechanisms will restore blood volume with
in 24 hours
Class II Hemorrhage Defined - ANSWERS-Is in complicated
hemorrhage for which crystalloid fluid resuscitation is
required.
, 15% - 30% blood volume loss
Tachycardia
Tachypnea
Decrease pulse pressure (r/t catacholamine releases
resulting in increased vascular tone)
Subtle CNS changes ( anxiety, fear, hostility)
Urinary output only mildly affected (20 - 30 ml/ hr in class
II)
Class III Hemorrhage - Defined - ANSWERS-Is a complicated
hemorrhage state in which at least crystalloid infusion is
required and perhaps also blood replacement therapy
31% to 40%. Blood Volume Loss
Marked tachycardia
Tachypnea
Significant changes in mental status
Measurable fall isn systolic BP
Most patients in this category will require packed red blood
cells and blood products to reverse the shock state.
