ATLS10 exam questions with answers (answers outlined!!)

... [Show More] 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 largecaliber IVs are initiated. Arterial blood gases are obtained. His PaO2 is 118

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 trauma
b. Oxygen by non-rebreathing mask
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 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 xray reveals correct
placement of the chest tube and a small residual hemothorax. His blodd
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 crash after having ridden
for hours on a very hot day. When he arrives in the emergency department,
he shouts that he cannot move his legs. On physical examination, there are
no abnormalities of the chest, abdomen, or pelvis. The patient has no
sensation in his legs and cannot move them, but his arms are moving. The
patient’s respiratory rate is 22, heart rate is 88, and blood pressure is 80/60
mmHg. He is pale and sweaty. What is the most likely cause of his
hypotension?
a. Neurogenic shock
b. Cardiac tamponade
c. Myocardial contusion
d. Hyperthermia
e. Hemorrhagic shock
6. Comapred with adults, children have:
a. A longer, wider, funnel-shaped airway
b. A less pliable, calcified skeleton
c. Greater mobility of mediastinal structures
d. A relatively smaller head and larger jaw
e. Anterior displacement of C5 on C6
7. Which one of the findings below requires a definitive airway in trauma
patients?
a. Facial lacerations
b. Repeated vomiting
c. Partial thickness facial burns, cough, and hoarseness
d. Sternal fracture
e. Glascow Coma Scale score of 12
8. In a patient with spinal cord injury, sacral sparing:
a. Refers to a fracure of the sacrum
b. Is part of the spinal shock syndrome
c. Is a good prognostic sign
d. Indicates a complete spinal cord injury
e. Occurs only with complete transection of the lumbosacral spinal cord
9. A 22-year-old woman falls whil skiing. She is evaluated at a small
community hospital that does not have neurological services. Spinal motion
is restricted, supplemental oxygen by mask is administered, and two
antecubital IVs are placed. Her Glascow Coma Scale score is 12, pupils are
equal, blood pressure is 135/76 mmHg, heart rate is 105, and respiratory
rate is 19. Chest x-ray is normal. This patient’s management priorities are:
a. Repeat primary survey and transfer to a trauma center
b. Definitive airway, CT of the head, and intracranial pressure monitor
c. IV mannitol, definitive airway, CT of the head, and neurosurgery consult
d. CT of the head, EEG, cerebral perfusion pressure monitoring, and
hypertonic saline
e. IV Dilantin, IV mannitol, mild hyperventilation, and serial arterial blood
gases
10. A young male patient is brought to the emergency department following a 5-
meter (16-foot) fall from a roof. He responds to pressure by pushing away
your hand, opening his eyes, and verbalizing inappropriate words. Pupils
are equal. The most important step is management of this patient would
be:
a. Immidiate intubation to protect his airway
b. Administer 25 mg/kg IV bolus mannitol
c. Insert two large-bore IVs
d. Alcohol and drug screening
e. Determine whether amnesia is present and, if so, for what period of
time
11. Twenty-seven patients are seriously injured in an airplane crash at a local
airport.
The principles of triage include:
a. Establish a triage site whthin the hot zone of the crash site
b. Treat only the most severely injured patients first
c. Immidiately transport all patients to the nearest hospital
d. Treat the greatest number of patients in the shortest period of time
e. Produce the greatest number of survivors based on available resources
12. A 35-year-old female falls down a flight of stairs. She has extensive bruising
of her face and head. Her heart rate is 120, blood pressure 90/70 mmHg,
and respiratory rate is 26. The patient`s condition is most readily explained
by:
a. Associated head injury
b. Hypovolemia from hemorrhagic shock
c. Alcohol intoxication
d. Spinal shock from cervical spine injury
e. Neurogenic shock from cervical spine injury
13. Which one of the following statements is correct:
a. Cerebral contusions may coalesce to form an intracerebral hematoma
b. Epidural hematomas are usually seen in the frontal region
c. Subdural hematomas are caused by injury to the middle meningeal
artery
d. Subdural hematomas typically have a lenticular shape on CT scan
e. The associated brain damage is more severe in epidural hematomas
14. An 18-year-old is brought to the emergency department after having been
shot. He has one bullet wound just below the right clavicle and another just
below the costal margin in the right posterior axillary line. His blood
pressure is 110/60 mmHg, heart rate is 90 beats per minute, and respiratory
rate is 34 breaths per minute. After ensuring a patent airway and inserting
two large-caliber IV lines, the next appropriate step is to:
a. Obtain a portable chest x-ray
b. Administer a bolus of additional IV fluid
c. Perform a laparotomy
d. Obtain an abdominal CT scan
e. Perform diagnostic peritoneal lavage
