Pathology of shock

Question 1

in shock there is hyperperfusion of tissue which leads to cellular hypoxia
T or F

Answer 1

F
hypoperfusion - reduced tissue perfusion

Question 2

if shock persists there would be irreversible tissue injury
T or F

Answer 2

T

Question 3

List the 5 types of shock

Answer 3

Cardiogenic shock
hypovolemic shock
shock associated with systemic inflammation
neurogenic shock
anaphylactic shock

Question 4

in cardiogenic shock there is fall in cardiac output and blood volume
T or F

Answer 4

F
there is no fall in blood volume
the above is a characteristic of hypovolemic shock

Question 5

cardiogenic shock results from

Answer 5

myocardial pump failure
which may be due to certain reasons

Question 6

list the 3 major causes of myocardial pump failure (cardiogenic shock)

Answer 6

Deficient emptying
Deficient filling
obstruction to outflow

Question 7

cardiac tamponade causes cardiogenic shock by preventing the heart from?

Answer 7

Filling properly

nb: cardiac tamponade is when excess fluid is present in your pericardial sac and thus compresses the heart preventing it from expanding properly during filling

Question 8

causes of hypovolemic shock can be divided into two categories which are

Answer 8

Hemorrhagic - blood loss
non - Hemorrhagic - fluid loss e.g burns, diabetes, diarrhea

Question 9

anaphylactic shock is mediated by what ig

Answer 9

igE

Question 10

list two common causes of neurogenic shock

Answer 10

anesthetic accident
spinal cord injury

Question 11

in neurogenic shock there is vasodilation of blood vessels and loss of nerve stimulation to blood vessels
T or F

Answer 11

T
in neurogenic shock there is loss of central control from the CNS to increase blood pressure leading to hypotension then subsequent tissue hypoperfusion
