ARC burn.

motor vehicle collision. Which of the following is the most reliable indication of shock in
this patient?
LEVEL OF CONSCIOUSNESS.
Which of the following findings is not expected in assessment of a pregnant patient?
A DECREASED BLOOD PRESSURE IN THE THIRD TRIMESTER.
Which of the following is contraindicated in the management of a pregnant trauma patient
in the third trimester?
,SUPINE POSITION.
During the assessment of the trauma patient, auscultation of the lung sounds is first
performed during:
THE PRIMARY SURVEY.
Which of the following is indicated for the prehospital management of a circumferential
second degree burn extending from the wrist to the elbow in a 70 Kg patient?
A DRY STERILE DRESSING
ANALGESIA
The preferred fluid for resuscitation of the patient with significant burns is:
LACTATED RINGER'S SOLUTION.
Which of the following is the most common cause of spinal injuries?
MOTOR VEHICLE COLLISIONS.

Cardiac tamponade is suspected with the findings of muffled heart sounds___________,
and___________ known as___________.
JUGULAR VEIN DISTENTION, and HYPOTENSION, known as BECK'S TRIAD.
When administering isotonic crystalloid solution, about ___________ will remain in the
vascular system after 1 hour.
ONE-THIRD
PASG is contraindicated in patients with
CHEST TRAUMA.
The greatest threat to life from injury to hollow abdominal organ is
PERITONITIS.
IV fluids administered to patients in shock should be _______ in order to ______________
______________.
WARM, PREVENT HYPOTHERMIA.
During pregnancy, signs and symptoms of shock may appear _______ due to an _________
in maternal blood volume.

A fractured femur can result in___________________mL of hemorrhage.
1000 TO 2000
A male patient suffered a stab wound to his left flank. He is found to be in stage III shock.
During the 25 minute transport to the trauma center, intravenous fluids should be
administered at a rate sufficient to maintain a:
SYSTOLIC BP OF 80 TO 90.
The most common type of shock in trauma patients is
HYPOVOLEMIC.
What percentage of blood volume loss in an adult patient is associated with findings of
tachycardia (>120/beats/minute), tachypnea (30-40 Breaths/min), and hypotension (systolic
BP <90mmHg)?

Any patient that has a compromise to Airway, Breathing, Circulation and Deficit. Any Patient
that is Altered or
