ATLS 10 MCQ
Q:
A 42-year-old man is trapped from the waist down beneath his overtumed tractor for several hours before medical
assistance arrives. He is awake and alert until just before arriving in the emergency department. He is now
unconscious and responds only to painful stimuli by moaning. His pupils are 3 mm 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 emergency department, no movement of his lower extremities is detected, even
in response to painful stimuli. The most likely cause for this fmding is
A:
an epidural hematoma.
a pelvic fracture.
central cord syndrome.
intracerebral hemorrhage.
(E) bilateral compartment syndrome.
Q:
Twenty-seven patients are seriously injured in an aircraft accident at a local airport. The basic principle of triage
should be to
A:
treat the most severely injured patients first. establish a field triage area directed by a doctor. rapidly
transport all patients to the nearest appropriate hospital. treat the greatest number of patients in the shortest
period of time. produce the greatest number of survivors based on available resources
Q:
The response to catecholamines in an injured, hypovolemic pregnant woman can be expected to result in
A:
, placental abruption. fetal hypoxia and distress. fetal/maternal dysrhythmia. improved uterine
blood flow. increased maternal renal blood flow.
Q:
A 30-year-old man is struck by a car traveling at 56 kph (35 mph). He has obvious fractures of
the left tibia near the knee, pain in the pelvic area, and severe dyspnea. His heart rate is 180 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 140 beats per minute, his respiratory rate
decreases to 36 breaths per minute, and his blood pressure is 80/50 inm Hg. Warmed Ringer's
lactate is administered intravenously. The next priority should be to:
A:
perform a urethrogram and cystogram. perform external fixation of the pelvis.
obtain abdominal and pelvic CT scans. perform arterial embolization of the pelvic vessels.
perform diagnostic peritoneal lavage or abdominal ultrasound.
Q:
A 32-year-old man is brought to the hospital unconscious with severe facial injuries and noisy
respirations after an automobile collision. In the emergency department, he has no apparent
injury to the anterior aspect of his neck. He suddenly becomes apneic, and attempted ventilation
with a face mask is unsuccessful. Examination of his mouth reveals a large hematoma of the
pharynx with loss of normal anatomic landmarks. Initial management of his airway should
consist of
A:
inserting an oropharyngeal airvvay. inserting a nasopharyngeal airway. performing a
surgical cricothyroidotomy. performing fiberoptic-guided nasotracheal intubation.
performing orotracheal intubation after obtaining a lateral c-spine x-ray
