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
Which of the following would MOST likely result in hemorrhagic shock?
Severe vomiting
Liver laceration
Excessive sweating
Repeated diarrhea
All of the following conditions should make you suspect shock, EXCEPT:
anaphylaxis
spinal injury
severe infection
ischemic stroke
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:
apply pressure to the brachial artery
apply a tourniquet proximal to the wrist
administer high-flow supplemental oxygen
wrap the towel with pressure bandages
To protect vital organs, the body compensates by directing blood flow away from organs that are more tolerant of low flow, such as:
the skin
the heart
the brain
the lungs
Pulmonary edema and impaired ventilation occur during:
septic shock
neurogenic shock
cardiogenic shock
anaphylactic shock
Cardiogenic shock may result from all of the following, EXCEPT:
heart attack
increased afterload
increased preload
poor contractility
When auscultating the lungs of a patient with respiratory distress, you hear adventitious sounds. This means that the patient has:
normal breath sounds
abnormal breath sounds
diminished breath sounds
an absence of breath sounds
When assessing for fluid collection in the lungs during auscultation of lung sounds, you should:
note the presence of a high-pitched whistling sound, which is an indicator of fluid in the lungs
pay special attention to the exhalation phase because this is when you will likely hear rales or rhonchi
auscultate the posterior chest first and compare the apex of one lung to the base of the opposite lung
start at the lower lung fields and determine at which level you start hearing clear breath sounds
Which of the following statements regarding pulse oximetry is correct?
The pulse oximeter is a valuable assessment tool that measures the percentage of red blood cells that contain hemoglobin molecules
Caution must be exercised when using the pulse oximeter on a patient with carbon monoxide poisoning because falsely low readings are common
Pulse oximetry measures the percentage of hemoglobin that is saturated with oxygen but does not measure the actual hemoglobin content of the blood
Most otherwise healthy patients can maintain adequate oxygenation and good skin color with oxygen saturation readings as low as 70% to 80%
When the level of arterial carbon dioxide rises above normal:
the brain stem inhibits respirations
respirations increase in rate and depth
exhalation lasts longer than inhalation
respirations decrease in rate and depth
