Quiz 13 - Cardiovascular Shock

Question 1

If not corrected cardiogenic shock can progress to:

Answer 1

hypovolaemic shock.

Question 2

Neurogenic shock can be caused by any factor that inhibits the:

Answer 2

sympathetic nervous system.

Question 3

During shock states, glucose uptake is usually:

Answer 3

impaired

Question 4

When a person is in shock, impairment in cellular metabolism is caused by:

Answer 4

inadequate tissue perfusion.

Question 5

Causes of neurogenic shock include:

a. trauma to the spinal cord.
b. depressive drugs.
c. decreased cerebral perfusion.
d. anaesthetic drugs.
e. all of the above.

Answer 5

all of the above.

Question 6

The most common cause of multiple organ dysfunction syndrome (MODS) is:

Answer 6

septic shock.

Question 7

A 20-year-old female is being admitted to hospital with fever and septic shock. Which set of clinical manifestations would you expect her to exhibit?

Answer 7

low blood pressure, tachycardia, generalised oedema

Question 8

Systemic inflammatory response syndrome (SIRS) begins with an infection that progresses to:

a. bacteremia
b. sepsis.
c. septic shock.
d. multiple organ dysfunction syndrome (MODS).
e. all of the above

Answer 8

all of the above.

Question 9

The onset of anaphylactic shock is usually:

Answer 9

immediate and life threatening

Question 10

One consequence of switching from aerobic to anaerobic cellular metabolism during shock states is:

Answer 10

decreased ATP production.

Question 11

A 15-year-old male who is allergic to peanuts inadvertently eats something containing peanuts. He then goes into anaphylactic shock and develops:

Answer 11

bronchoconstriction, hives, oedema and hypotension.

Question 12

Compensatory mechanisms for hypoperfusion of tissues during shock include:

Answer 12

sympathetic nervous system stimulation.

Question 13

An 82-year-old female was admitted to hospital with confusion and severe hypotension. Her body’s compensatory mechanisms are increased heart rate, vasoconstriction and movement of large volumes of interstitial fluid to the vascular compartment. What kind of shock do you suspect?

Answer 13

hypovolaemic

Question 14

Which of the following can all cause absolute hypovolaemic shock?

a. haemorrhage.
b. severe diarrheoa.
c. prolonged vomiting.
d. burns.
e. all of the above.

Answer 14

all of the above.

Question 15

The hypotensive state seen in septic shock can arise due to:

Answer 15

gut lining disruption and widespread inflammation

Question 16

Shock is a complex pathophysiological process involving all of the following EXCEPT:

a. decreased blood perfusion to kidneys.
b. acidosis.
c. rapid heart rate.
d. hypertension.
e. anaerobic glycolysis.

Answer 16

hypertension

Question 17

A 27-year-old male is admitted to a neurologic unit with a complete C-5 spinal cord transaction. On initial assessment, he is bradycardic, hypotensive and hyperventilating. He appears to be going into shock. The most likely mechanism of his shock is:

Answer 17

vasodilation caused by a decrease in sympathetic stimulation.

Question 18

A 50-year-old male was admitted to the intensive care unit with a diagnosis of acute myocardial infarction. He is being treated for shock. His cardiopulmonary symptoms include low blood pressure, tachycardia and tachypnoea. His skin is pale and cool. The primary cause of his shock is most likely:

a. rapid heart rate.
b. decreased cardiac contractility.
c. increased capillary permeability.
d. decreased afterload due to vasodilation.

Answer 18

b. decreased cardiac contractility.
