(MOST RECENT!!)
Q1. Perfusion
Correct Answer: Delivery of O2 and removal of CO2
Rationale: Perfusion requires a pump (heart), fluid (blood),
and vessels (arteries/veins). Without any of these three
components functioning properly, adequate tissue perfusion
cannot occur.
Q2. Hypoperfusion
Correct Answer: Inadequate flow of blood; i.e., SHOCK
Rationale: Hypoperfusion is the medical definition of
shock—a state where oxygen delivery to tissues is insufficient
to meet metabolic demands. This leads to cellular hypoxia
and, if uncorrected, organ failure.
,Q3. Hypovolemic shock
Correct Answer: Shock resulting from blood or fluid loss
Rationale: This is the most common type of shock
encountered in trauma. Causes include bleeding
(hemorrhage), burns (plasma loss), or dehydration (fluid loss).
The body loses circulating volume, reducing preload and
cardiac output.
Q4. Distributive shock
Correct Answer: Widespread vasodilation
Rationale: In distributive shock, blood vessels dilate
excessively, causing relative hypovolemia even though total
blood volume may be normal. Sepsis is a common cause—
bacterial toxins damage vessel walls, increasing capillary
permeability and reducing intravascular fluid.
Q5. How to treat septic shock?
Correct Answer: POWR: Position (supine), O2, Warmth,
Rapid transport
Rationale: The POWR acronym provides the standard EMT
approach: Position the patient supine to optimize perfusion,
administer high-flow Oxygen, maintain Warmth to prevent
hypothermia, and provide Rapid transport to definitive care.
Q6. Neurogenic shock
Correct Answer: Loss of control of muscular tone of blood
vessels due to spinal cord injury
Rationale: Damage to the sympathetic nervous system from
spinal cord injury removes vasoconstrictor tone. Unlike other
, shock states, patients typically present with hypotension AND
bradycardia (unopposed vagal tone), with warm, dry skin
below the level of injury.
Q7. Symptoms of neurogenic shock
Correct Answer: Hypotension and bradycardia; warm, dry
skin below injury
Rationale: This distinguishes neurogenic shock from
hypovolemic or cardiogenic shock, where patients present
with cool, clammy skin and tachycardia. The sympathetic
chain damage prevents the normal compensatory
tachycardia response.
Q8. Anaphylactic shock
Correct Answer: Severe allergic reaction leading to
widespread vasodilation
Rationale: Anaphylaxis causes massive histamine release,
resulting in increased vascular permeability,
bronchoconstriction, and vasodilation. Signs include stridor,
hives, edema, itching, and respiratory distress.
Q9. Cardiogenic shock
Correct Answer: Shock caused by inadequate function of the
heart (pump failure)
Rationale: While more common in medical patients, trauma
can cause cardiogenic shock through blunt cardiac injury,
myocardial contusion, or pericardial tamponade. The heart
fails to pump adequately despite adequate volume.
Q10. Obstructive shock
, Correct Answer: Something obstructs blood flow in the
body
Rationale: Causes include cardiac tamponade (blood in
pericardial sac compressing the heart), pulmonary embolism
(clot obstructing pulmonary circulation), or tension
pneumothorax (pressure shifting mediastinum and reducing
venous return).
Section 2: Stages of Shock
Q11. Compensated shock
Correct Answer: Early stage where body can still
compensate for blood loss
Rationale: Vital signs remain relatively normal, but subtle
signs appear: cool, pale, moist skin; slightly elevated pulse;
slightly elevated respirations. The body maintains blood
pressure through vasoconstriction and increased heart rate.
Q12. Decompensated shock
Correct Answer: Late stage when blood pressure is falling
Rationale: The body can no longer maintain perfusion. Signs
include lethargy, cool/pale/diaphoretic skin, dropping blood
pressure, weak pulse, and shallow breathing. This represents
a critical emergency requiring immediate intervention.
Q13. Irreversible shock
Correct Answer: Body has lost the battle to maintain
perfusion to vital organs
