A 17-year-old helmeted motorcyclist is struck broadside by an automobile at an intersection. He is
unconscious at the scene with a blood pressure of 140/90mmHg, heart rate of 90 beats per minute, and
respiratory rate of 22 breaths per minute. His respirations are sonorous and deep. His GCS score is 6.
Immobilization of the entire patient may include the use of all the following EXCEPT:
,A. Air splints
B. Bolstering devices
C. A long spine board
D. A scoop-style stretcher
E. A semi-rigid cervical collar - answer>>A. Air splints
A 24 year old pedestrian, struck by an automobile, is admitted to the ED 1 hour after injury. His BP is
80/60, HR 140, and RR 36. He is lethargic. Oxygen is delivered via face mask, and two large caliber IVs
are initiated. ABG is obtained: PaO2 118, PaCO2 30, pH 7.21. The treatment of his acid-base disorder is
best accomplished by:
A. Hyperventilation
B. Restoration of normal perfusion
C. Initiation of low dose dopamine
D. Administration of sodium bicarbonate
E. Initiation of phenylephrine infusion - answer>>B. Restoration of normal perfusion
During an altercation, a 36-year-old man sustains a gunshot wound above the nipple line on the right,
with an exit wound posteriorly above the scapula on the right. He is transported by ambulance to a
community hospital. He is endotracheally intubated, close tube thoracostomy is performed, and 2 liters
Ringers lactate solution are infused via 2 large-caliber IVs. His blood pressure now is 60/0mmHg, heart
rate is 160 beats per minute, and respiratory rate is 14 breaths per minute (ventilated with 100% O2).
The most appropriate next step in managing this patient is:
A. Laparotomy
B. Diagnostic peritoneal lavage
C. Arterial blood gas determination
D. Administer packed red blood cells
E. Chest X-ray to confirm tube placement - answer>>D. Administered packed red blood cells
,Which of the following statements regarding injury to the central nervous system in children is true? -
answer>>Children suffer spinal cord injury without an XR abnormality more commonly than adults
Which of the following physical findings does NOT suggest spinal cord injury as the cause of
hypotension?
A. Priapism
B. Bradycardia
C. Distended neck veins
D. Diaphragmatic breathing
E. Ability to flex forearms but inability to extend them - answer>>??
5 year old boy is struck by an automobile and brought to the emergency department. He is lethargic, but
withdraws purposefully from painfully stimuli. His blood pressure is 90 mmHg, HR 140 BPM, and RR is 36
bpm. The preferred route of venous access in this patient is: - answer>>Pertained veins in the upper
extremities
The response to catecholamines in an injured, hypovolemic pregnant woman can be expected to result
in:
A. Placental abruption
B. Fetal hypoxia and distress
C. Fetal/maternal dysrhytmia
D. Improved uterine blood flow
E. Increased maternal renal blood flow - answer>>B. Fetal hypoxia and distress
A construction worker falls from a scaffold and is transferred to the ED. His HR is 124 bpm and his BP is
85/60. He complains of lower abdominal pain. After assessing the airway and chest, immobilizing the C
spine and initiating fluid resuscitation, the next step is to perform:
A. FAST exam
B. Detailed neurological exam
, C. Rectal exam
D. Cervical spine x-ray
E. Urethral catheterization - answer>>A. FAST exam
Cardiac tamponade after trauma: - answer>>Can be confused with a tension pneumothorax
Cardic tamponade:
A. Requires surgical intervention
B. Is definitively managed by needle pericardiocentesis
C. Is easily diagnosed by Beck's triad
D. Is indicated by Kussmaul breathing
E. Is most common with blunt thoracic trauma and anterior rib fractures - answer>>??
30 year old man sustains a severely, communities, open distal right femur fracture in a motorcycle crash.
The wound is actively bleeding. DP and PT are easily palpable on the left, but heard only by Doppler on
the right. Immediate effort to improve circulation the injured extremity should involve: -
answer>>Tamponade of the wound with a pressure dressing
24 year old male sustains multiple fractured ribs bilaterally as a result of being crushed in a press at
plywood factory. Examination in the ED revealed a foil segment on the patient's thorax. Primary
resuscitation includes high flow, oxygen administration via a non-breathing mask, and initiation of
ringers lactate solution. The patient exhibits progressive confusion, cyanosis, and kidney. Management
at this time she consist of: - answer>>Endotracheal intubation and mechanical ventilation
23 year old man is brought immediately to the emergency department from the hospital parking lot
where he was shot in the lower abdomen. Examination reveals a single bullet wound. He is breathing
and has a thrash pulse. However, he is unconscious and has no detectable blood pressure. Optimal
immediate management is to: - answer>>Transfer the patient to the operating room while initiating
fluid therapy
