◉ 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 58mmHg.
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. Abdominal ultrasonography
,E. A diagnostic peritoneal lavage. Answer: A. Laparotomy because of
hemodynamic abnormality
◉ 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
◉ A 6-year-o boy is struck by an automobile and brought to the ED.

blood pressure is 90mmHg 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
◉ 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..
Answer:
C. Control internal hemorrhage operatively
◉ Regarding shock in the child, which of the following is FALSE?
A. Vital signs are age-related
B. Children have greater physiologic reserves than do adults
C. Tachycardia is the primary physiologic response to hypovolemia
