,1. Which of the following is the recommended method for treating frostbite?
A. Vasodilators
B. Anticipulants
C. Warm (40°C/104°F) water
D. Padding and elevation
E. Application of heat from a hairdryer
Answer: C. Warm (40°C/104°F) water
Rationale: Rapid rewarming in a water bath at 40°C (104°F) is the recommended treatment
for frostbite. This provides controlled warming without causing additional tissue damage from
excessive heat.
2. Which of the following physical findings suggest a cause of hypotension other than spinal cord
injury?
A. Priapism
B. Bradycardia
C. Diaphragmatic breathing
D. Presence of deep tendon reflexes
E. Ability to flex forearms but not extend them
Answer: D. Presence of deep tendon reflexes
Rationale: Spinal shock refers to loss of muscle tone (flaccidity) and loss of reflexes. The
presence of deep tendon reflexes indicates that the hypotension is not due to spinal shock,
suggesting another cause such as hypovolemic shock.
3. The primary indication for transferring a patient to a higher level trauma center is:
A. Unavailability of surgeon or operating staff
B. Multiple system injuries, including severe head injury
C. Resource limitations as determined by the transferring doctor
D. Resource limitations as determined by the hospital administration
,E. Widened mediastinum on chest x-ray following blunt trauma
Answer: C. Resource limitations as determined by the transferring doctor
Rationale: The transferring physician makes the clinical judgment that the patient's needs
exceed the facility's resources. This is the primary indication for transfer, based on medical
assessment of the patient's condition and available capabilities.
4. A young man sustains a rifle wound to the mid-abdomen. He is brought promptly to the ED by
prehospital personnel. His skin is cool and diaphoretic, and his systolic blood pressure is 58 mmHg.
Warmed crystalloid fluids are initiated without improvement in his vital signs. The next, most
appropriate step is to perform:
A. A laparotomy
B. An abdominal CT-scan
C. Diagnostic laparoscopy
D. Diagnostic peritoneal lavage (DPL) or FAST
Answer: A. A laparotomy
Rationale: This patient has a gunshot wound to the abdomen with profound hypotension
(systolic BP 58 mmHg) unresponsive to fluid resuscitation. Gunshot wounds to the abdomen that
traverse the peritoneal cavity require immediate surgical exploration. The patient is in
hemorrhagic shock from intra-abdominal bleeding and requires immediate operative intervention.
5. A 42-year-old man is trapped from the waist down beneath his overturned tractor for several
hours before medical assistance arrives. He is awake and alert until just before arriving in the ED.
He is now unconscious and responds only to painful stimuli by moaning. His pupils are 3mm in
diameter and symmetrically reactive to light. Prehospital personnel indicate that they have not
seen the patient move either of his lower extremities. On examination in the ED, no movement of
his lower extremities are detected, even in response to painful stimuli. The most likely cause for
this finding is:
A. An epidural hematoma
B. A pelvic fracture
C. Central cord syndrome
D. Intracerebral hemorrhage
E. Bilateral compartment syndrome
, Answer: E. Bilateral compartment syndrome
Rationale: Prolonged crush injury from being trapped beneath a heavy object can cause
bilateral compartment syndrome. The patient's unconsciousness and lack of lower extremity
movement may be due to the systemic effects of crush injury (rhabdomyolysis, metabolic
derangements) or compartment syndrome. The symmetric pupillary response and lack of
lateralizing signs make intracranial pathology less likely.
6. A 6-year-old boy is struck by an automobile and brought to the ED. He is lethargic, but
withdraws purposefully from painful stimuli. His blood pressure is 90 mmHg systolic, heart rate
140 beats per minute and his respiratory rate is 36 breaths per minute. The preferred route of
venous access in this patient is:
A. Percutaneous femoral vein cannulation
B. Cutdown on the saphenous vein at the ankle
C. Intraosseous catheter placement in the proximal tibia
D. Percutaneous peripheral veins in the upper extremities
E. Central venous access via the subclavian or internal jugular vein
Answer: D. Percutaneous peripheral veins in the upper extremities
Rationale: In children, the preferred initial route for venous access is percutaneous
cannulation of peripheral veins in the upper extremities. This is the least invasive and most rapid
method when veins are visible or palpable. Intraosseous access is reserved for situations where
peripheral access cannot be obtained rapidly.
7. A young man sustains a gunshot wound to the abdomen and is brought promptly to the ED by
prehospital personnel. His skin is cool and diaphoretic, and he is confused. His pulse is thready
and his femoral pulse is only weakly palpable. The definitive treatment in managing this patient is
to:
A. Administer O-negative blood
B. Apply external warming devices
C. Control internal hemorrhage operatively
D. Apply a pneumatic antishock garment (PASG)
E. Infuse large volumes of intravenous crystalloid solutions
