1. A 45-year-old patient presents with a penetrating chest
wound and BP 80/50 mmHg. Which type of shock is most
likely?
Answer: Hypovolemic
Rationale: Hypovolemic shock is caused by blood loss from
penetrating trauma, leading to low BP and tachycardia. TNCC
9th Ed., Ch. 6
2. A patient with hypovolemic shock has a heart rate of 120
bpm and cool, clammy skin. What is the priority intervention?
Answer: Control bleeding and give fluids
Rationale: Controlling bleeding and restoring volume with
fluids are critical in hypovolemic shock to stabilize
hemodynamics
,3. Which assessment finding indicates cardiogenic shock in a
trauma patient?
Answer: Pulmonary edema
Rationale: Cardiogenic shock from cardiac injury causes
pulmonary edema due to impaired cardiac output
4. A patient with a spinal cord injury presents with BP 90/60
mmHg and heart rate 50 bpm. What type of shock is
suspected?
Answer: Neurogenic
Rationale: Neurogenic shock from spinal injury causes
vasodilation and bradycardia, leading to hypotension
5. In distributive shock, what is the primary physiological
change?
Answer: Vasodilation
Rationale: Distributive shock (e.g., septic, neurogenic)
involves vasodilation, reducing systemic vascular resistance
6. A patient in shock receives 2 L of crystalloids with no BP
improvement. What is the next step?
Answer: Administer blood products
Rationale: Persistent hypotension after crystalloids suggests
severe blood loss, requiring blood products to restore
oxygen-carrying capacity
7. Which medication is used for neurogenic shock to improve
perfusion?
, Answer: Norepinephrine
Rationale: Norepinephrine increases vasoconstriction,
improving BP in neurogenic shock
8. A patient with suspected obstructive shock has jugular vein
distension. What is the likely cause?
Answer: Tension pneumothorax
Rationale: Tension pneumothorax causes obstructive shock
with jugular vein distension due to increased intrathoracic
pressure
9. Which finding indicates decompensated shock in a trauma
patient?
Answer: Altered mental status
Rationale: Decompensated shock occurs when
compensatory mechanisms fail, leading to decreased cerebral
perfusion and altered mental status
10. A trauma patient who is 30-weeks pregnant arrives
following an MVC. Which normal physiologic change should
be considered when assessing ventilatory status?
Answer: Increased oxygen consumption
Rationale: Pregnancy increases metabolic demands and
oxygen consumption, making pregnant patients more
vulnerable to hypoxia during shock states
11. A driver involved in a high-speed MVC arrives drowsy but
arousable, with chest pain and ecchymosis. The patient is
tachycardic and hypotensive with PVCs on monitor. What is
the most appropriate intervention?
, Answer: Inotropic support
Rationale: These findings suggest myocardial contusion
(blunt cardiac injury) causing cardiogenic shock. Inotropic
support improves cardiac contractility
12. What is the rationale for obtaining a serum lactate level
during initial assessment?
Answer: To gauge end-organ perfusion and tissue hypoxia
Rationale: Elevated lactate indicates anaerobic metabolism
from inadequate tissue perfusion
13. What is the best measure of the adequacy of cellular
perfusion?
Answer: Base deficit
Rationale: Base deficit reflects metabolic acidosis from
hypoperfusion and helps predict resuscitation outcomes
14. A severely injured intubated patient has received balanced
resuscitation including multiple blood products. Under which
circumstance will it be harder for hemoglobin to release
oxygen to tissues?
Answer: Decreased body temperature
Rationale: Hypothermia shifts the oxyhemoglobin
dissociation curve left, causing hemoglobin to hold oxygen
more tightly
15. What component of the trauma triad of death is most
likely to have begun at the time of injury?
Answer: Coagulopathy
