1. In an adult trauma patient with suspected hemorrhagic shock, the
primary goal of initial fluid resuscitation is to:
A. Normalize the blood pressure immediately
B. Restore circulating volume while controlling hemorrhage
C. Produce urine output above 2 mL/kg/hr
D. Administer large volumes of crystalloid before definitive
hemorrhage control
Answer: B. Restore circulating volume while controlling hemorrhage
Rationale: Fluid resuscitation supports perfusion, but it does not
replace hemorrhage control. Excessive crystalloid administration can
worsen dilutional coagulopathy, hypothermia, and tissue edema.
2. Which finding most strongly suggests inadequate tissue perfusion
in a bleeding trauma patient?
A. Warm skin
B. Mild hypertension
C. Altered mental status with delayed capillary refill
D. Increased appetite
Answer: C. Altered mental status with delayed capillary refill
,Rationale: Altered mentation and delayed peripheral perfusion can
indicate inadequate oxygen delivery. Trauma assessment should
integrate mental status, pulse quality, skin findings, urine output, and
laboratory trends rather than relying on blood pressure alone.
3. Which mechanism most commonly causes hypovolemic shock
after major trauma?
A. Loss of circulating blood volume
B. Excessive insulin secretion
C. Increased red-cell production
D. Isolated hyperventilation
Answer: A. Loss of circulating blood volume
Rationale: Hemorrhagic shock results primarily from loss of
circulating blood. Reduced preload decreases cardiac output and
ultimately compromises oxygen delivery to tissues.
4. A trauma patient has severe external bleeding. What should occur
before attempting definitive fluid optimization?
A. Delay hemorrhage control until laboratory results return
B. Initiate hemorrhage-control measures immediately
C. Administer unlimited crystalloid
D. Give diuretics
Answer: B. Initiate hemorrhage-control measures immediately
Rationale: Resuscitation cannot compensate for uncontrolled bleeding.
Direct pressure, tourniquet application when appropriate, pelvic
stabilization, surgery, or other definitive measures should occur
promptly.
5. Which clinical concept best describes the danger of excessive
crystalloid administration during uncontrolled hemorrhage?
, A. Improved clot stability
B. Dilutional coagulopathy and increased bleeding
C. Permanent hypertension
D. Increased red-cell mass
Answer: B. Dilutional coagulopathy and increased bleeding
Rationale: Large crystalloid volumes can dilute coagulation factors
and platelets while contributing to hypothermia and edema. These
effects may interfere with effective hemostasis.
6. In a trauma patient with suspected major hemorrhage, which
vascular access is generally preferred when rapidly obtainable?
A. Peripheral intravenous access
B. Arterial catheter only
C. Urinary catheter
D. Central venous access as the only option
Answer: A. Peripheral intravenous access
Rationale: Large-bore peripheral IV access can usually be established
rapidly and is appropriate for initial resuscitation. If peripheral access
cannot be obtained promptly, intraosseous access is an important
alternative.
7. When conventional intravenous access cannot be rapidly
established in a critically injured patient, which route provides
rapid vascular access?
A. Intramuscular
B. Intraosseous
C. Subcutaneous
D. Intradermal
Answer: B. Intraosseous
, Rationale: Intraosseous access provides rapid entry into the vascular
system and can be used for fluids, blood products, and medications
during emergency resuscitation when IV access is difficult.
8. Which component of trauma resuscitation should receive priority
over repeated fluid boluses when active hemorrhage is evident?
A. Definitive hemorrhage control
B. Routine nutritional supplementation
C. Long-term rehabilitation
D. Oral hydration
Answer: A. Definitive hemorrhage control
Rationale: Ongoing blood loss must be stopped. Continuing to
administer fluid without controlling the source can increase
intravascular pressure while failing to restore effective circulating
blood volume.
9. A patient with uncontrolled torso hemorrhage has a palpable radial
pulse but remains confused. Which interpretation is most
appropriate?
A. Adequate resuscitation is guaranteed
B. Tissue perfusion may still be inadequate
C. Shock has been excluded
D. No further assessment is necessary
Answer: B. Tissue perfusion may still be inadequate
Rationale: A palpable pulse does not prove adequate cellular perfusion.
Mental status and other indicators may reveal ongoing oxygen-
delivery failure despite apparently acceptable peripheral pulses.
10. Which principle is most consistent with modern trauma
resuscitation?
