EMT Chapter 13

 Shock is the result of:

• hypoperfusion to the cells of the body

• the body’s maintenance of homeostasis

•  temporary dysfunction of a major organ

• widespread constriction of the blood vessels

Capillary sphincters are:

• under complete control of the voluntary portion of the nervous system

• capable of dilating in order to increase perfusion to crucial body organs

•  responsible for constricting to compensate for decreased cell perfusion

• circular muscular walls that regulate blood flow through the capillaries

One of the primary waste products of normal cellular metabolism that must be removed from the body by the lungs is:

•  lactic acid

• carbon dioxide

• pyruvic acid

• carbon monoxide

Which of the following injuries would MOST likely cause obstructive shock?

•  Liver laceration

• Cardiac tamponade

• Simple pneumothorax

• Spinal cord injury

Which of the following clinical signs is unique to anaphylactic shock?

• Pallor

• Dizziness

• Wheezing

• Hypotension

Hypovolemic shock caused by severe burns is the result of a loss of: 

• plasma

• platelets

• whole blood

• red blood cells

Neurogenic shock occurs when:

•  failure of the nervous system causes widespread vasodilation

•  the spinal cord is severed and causes massive hemorrhaging

• there is too much blood to fill a smaller vascular container

• massive vasoconstriction occurs distal to a spinal cord injury

In an acute injury setting, neurogenic shock is commonly accompanied by:

• hypovolemia

• tachycardia

• diaphoresis

• hypothermia

Clinical signs of compensated shock include all of the following, EXCEPT:

• cool and clammy skin

•  absent peripheral pulses

•  restlessness or anxiety

• rapid, shallow breathing

Which of the following patients is in decompensated shock?

• A 20-year-old female with absent radial pulses and dilated pupils

• A 23-year-old restless male with cool, clammy skin and tachycardia

• A 28-year-old female with pale skin and rapid, shallow respirations

• A 32-year-old male with anxiety and a systolic blood pressure of 110 mm Hg
