Class III hemorrhage indicates what % of blood loss - CORRECT ANSWERS35%
Management of a stable patient with kidney contusion - CORRECT ANSWERSObservation
Associated with hypovolemic shock - CORRECT ANSWERS-Inadequate tissue perfusion with resultant
tissue hypoxia
-Blood shunting to vital organs
-Decreased circulating blood volume and decreased venous return
-Low cardiac output
-Loss of less than 20% of the blood volume is usually without symptom except for mild tachycardia
-Patients become orthostatic with losses between 20 and 40%
-Shock is evidenced by tachycardia, hypotension, oliguria, flat neck veins

First priority in the treatment of an unconscious patient - CORRECT ANSWERSChecking the pulse
A patient involved in a road accident is brought to the emergency department in an unconscious state.

On physical examination, she has no obvious sign of external bleeding. Which of the following cannot be
the cause of hypotension in this patient?
A. Pelvic fracture
B. Fracture of femur
C. Intracranial hemorrhage
D. Hemothorax - CORRECT ANSWERSC. Intracranial hemorrhage

B. Close the wound in the ER
C. Take him to the operating room
D. CT scan to evaluate neck structure - CORRECT ANSWERSC. Take him to the OR
