ANSWERS 320+ QUESTIONS AND ANSWERS|
GRADED A
Which of the following physical findings suggest a cause of hypotension other than
spinal cord injury? A. Prispism 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. Spinal shock refers to loss of muscle toe (flaccidty) and loss of
reflexes.
The primary indication for transferring A patient to a higher level trauma center is:

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 (MÅ SJEKKES)
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- MÅ SJEKKES
A 6-year-o boy is struck by an automobile and brought to the ED. He is lethargic,
but withdraws purposefully from painful stimuli. His 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
D. The absolute volume of blood loss required to produce shock is the same as in
adults
E. An initial fluid bolus for resuscitation should approximate 20ml/kg Ringers
Lactate -ANSWER- D. The absolute volume of blood loss required to produce
shock is the same as in adults
A 33-year-old man is struck by a car travelling at 56km/h (35mph). He has obvious
fractures of the left tibia near the knee, pain in the pelvic area, and severe dyspnea.
His heart rate is 182 beats per minute, and his respiratory rate is 48 breaths per
minute with no breath sounds heard in the left chest. A tension pneumothorax is
relieved by immediate needle decompression and tube thoracostomy.
Subsequently, his heart rate decreases to 144 beats per minute, his respirartory rate
decreases to 36 breaths per minute and his blood pressure is 81/53 mmHg.
Warmed Ringers lactate is adminstered intravenously. The next priority should be
to:
A. Perform external fixation of the pelvis
B. Obtain abdominal and pelvic CT-scans
C. Perform arterial embolization of the pelvic vessel
D. Perform diagnostic peritoneal lavage or FAST
E. Perform a urethrogram and cystogram -ANSWER- D. Perform diagnostic
peritoneal lavage or FAST
A 42-year-old man, injured in a motor vehicle crash, suffers a closed head injury,
multiple palpable left rib fractures, and bilateral femur fractures. He is intubated
orotracheally without difficulty. Initially, his ventilations are Reasily assisted with
, lOMoAR cPSD| 37417828
a bag-mask device. It becomes more difficult to ventilate the patient over the next
5 minutes, and his hemoglobin oxygen saturation level decreases from 98% to
89%. The most appropriate next step is to:
A. Obtain a chest x-ray
B. Decrease the tidal
volume C. Decrease PEEP
D. Increase the rate of assisted ventilations
E. Perform needle decompression of the left chest. -ANSWER- A. Obtain a chest
x-ray (MÅ SJEKKES)
A 30-year-old man sustains a severely comminuted, open, distal right femur
fracture in a motorcycle crash. The wound is actively bleeding. Normal sensation
is present over the lateral aspect of the foot but decreased over the medial foot and
great toe. Normal motion of the foot is observed. Dorsalis pedis and posterior tibial
pulses are easily palpable on the left, but heard only by Doppler on the right.
Immediate efforts to improve circulation to the injured extremity should involve:
A. Immediate angiography
B. Tamponade of the wound with a pressure dressing
C. Wound exploration and removal of bony fragments
D. Realignment of the fracture segments with a traction splint
E. Fasciotomy of all four compartments in the lower extremity -ANSWER- B.
Tamponade of the wound with a pressure dressing
An 18-yeard-old, unhelmeted motorcyclist is brought by ambulance to the ED
following a crash. He had decreased level of consciousness at the scene, but then
was alert and conversational during transportation. Now his GCS is only 11.
Which of the following statements is TRUE?
A. Cerebral perfusion is intact
B. Intravascular volume status is normal
C. The patient is in a postictal state
D. Intra-abdominal visceral injury is unlikely
E. The patient probably has an acute epidural hematoma -ANSWER- E. The
patient probably has an acute epidural hematoma
A previously healthy, 70kg (175 pound) man suffers an estimated acute blood loss
of two liters. Which one of the following statements apply to this patient?
A. His pulse pressure will be widened
B. His urinary output will be at the lower limits of normal
