EXAM QUESTIONS VERIFIED ANSWERS
1. A 24 year old male pedestrian, struck by an B
automobile, is admitted to the emergency
department 1 hour after injury. His blood pressure
is 80/60 mmHg, heart rate 140 beats per minute
and respiratory rate is 36 per minute. He is
lethargic. Oxygen is delivered via face mask, and
two large-caliber IVs are initiated. Arterial blood
gases are obtained. His PaO2 is 118 mmHg,
PaCO2 is 30 mmHg, and pH is 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 phenyl epinephrine infusion
2. The highest priority in managing a patient whose D
injuries include closed extremity fractures is:
A. Assessing limb perfusion
B. Preventing necrosis of the skin
C. Decompressing compartment syndrome
D. Addressing respiratory insufficiency
E. Identifying crush syndrome
3. A 34-year-old female is involved in a motor B
vehicle crash is brought to the emergency
department. She is talking, but her voice is hoarse
and on exposure she has diagonal bruising of the
chest and anterior neck. What is the next step?
A. Direct laryngoscopy to exclude laryngeal

C. Protecting the spine by making her lie down
D. Palpation of the anterior neck
E. Attaching a pulse oximeter to her finger
4. A 30-year-old male sustains a gunshot wound to D
the right lower chest, midway between the nipple
, and the costal margin. He is brought by
ambulance to a hospital that has full surgical
capabilities. In the emergency department he is
endotracheally intubated, fluid resuscitation is
initiated through two large-caliber IV lines, and a
closed tube thoracostomy is performed, with the
return of 200 ml of blood. A chest x- ray reveals
correct placement of the chest tube and a small
residual hemothorax. His blood pressure is now
70/0 mmHg, and his heart rate is 140 beats per
minute. His hypotension is most likely due to:
A. Tension pneumothorax
B. Massive hemothorax
C. Pericardial tamponade
D. Intraabdominal bleeding
E. Insufficient isotonic crystalloid infusion
5. A 20-year-old athlete is involved in a motorcycle E
crash after having ridden for hours on a very hot
