Ch. 13 Flashcards
A 20-year-old male has a large laceration to his wrist. He is holding a blood-soaked towel over the wound, but it continues to bleed rapidly. You should:
-Administer high-flow supplemental oxygen
-Apply a tourniquet proximal to the wrist
-Wrap the towel with pressure bandages
-Apply pressure to the brachial artery
Apply a tourniquet proximal to the wrist
All of the following condition should make sure suspect shock, EXCEPT:
-Severe infection
-Spinal injury
-Ischemic stroke
-Anaphylaxis
Ischemic stroke
Cardiogenic shock may result from all of the following, EXCEPT:
-Heart attack
-Increased preload
-Poor contractility
-Increased afterload
Increased preload
Clinical signs of compensated shock include all the following, EXCEPT:
-Absent peripheral pulses
-Cool and clammy skin
-Rapid, shallow breathing
-Restlessness or anxiety
Absent peripheral pulses
Hypovolemic shock caused by severe burns is the result of a loss of:
-Red blood cells
-Platelets
-Plasma
-Whole blood
Plasma
Neurogenic shock occurs when:
-There is too much blood to fill a smaller vascular container
-Massive vasoconstriction occurs distal to a spinal cord injury
-Failure of the nervous system causes widespread vasodilation
-The spinal cord is severed and causes massive hemorrhaging
Failure of the nervous system causes widespread vasodilation
Shock is the result of:
-Widespread constriction of the blood vessels
-Temporary dysfunction of a major orgna
-Hypoperfusion to the cells of the body
-The body’s maintenance of homeostasis
Hypoperfusion to the cells of the body
To protect vital organs, the body compensates by directing blood flow away from organs that are more tolerant of low flow, such as:
-The heart
-The lungs
-The brain
-The skin
The skin
Which of the following clinical signs is unique to anaphylactic shock?
-Dizziness
-Hypotension
-Pallor
-Wheezing
Wheezing
Which of the following patients is in decompensated shock?
-A 28-year-old female with pale skin and rapid, shallow respirations
-A 20-year-old female with absent radial pulses and dilated pupils
-A 23-year-old male with cool, clammy skin and tachycardia
-A 32-year-old male with anxiety and a systolic blood pressure of 110 mm Hg
A 20-year-old female with absent radial pulses and dilated pupils
