BSC + CCS: WK1-2 Flashcards
(198 cards)
the CNS ischaemic response:
a) increases cardiac output
b) increases peripheral vasoconstriction
c) activates the sympathetic nervous system
d) all of the above
d
pleuritic pain is felt often in all but:
a) costal pleura to chest (T2-6)
b) mediastinal pleura to shoulder tip (C4)
c) diaphragmatic pleura central to shoulder tip and peripheral to anterior abdominal wall
d) felt in all of the above
d
what is the primary difference between regurgitation and stenosis of valves?
regurgitation –> valve is leaking and not shutting properly and enabling backflow
stenosis –> narrow so little blood is getting through
which of these regarding shock is false?
a) failure of circulatory system
b) insufficient tissue perfusion
c) insufficient oxygen and nutrients to sustain aerobic metabolism
d) none of the above
d
true or false: decrease in blood pressure causes a decrease in the baroreceptor flex and thus an increase in SNS response and MAP
true
normal pH is around:
a) 7
b) 7.2
c) 7.4
d) 7.6
c
the easiest way to distinguish between the internal and external carotid arteries are:
external artery will have lots of branches coming off it
anastomoses is:
a) a connection or opening between mulitple things that are normally diverging, with an intervening capillary bed
b) a connection or opening between two things that are normally diverging, with an intervening capillary bed
c) a connection or opening between multiple things that are normally diverging, without an intervening capillary bed
d) a connection or opening between two things that are normally diverging, without an intervening capillary bed
d
The three branches of the left coronary artery are:
circumflex, marginal, left anterior descending (interventricular) artery
the coeliac trunk is found at __, the superior mesentery artery is found at ___ ,the inferior mesenteric artery is at ___ and the bifurcation of the abdominal aorta is at ___
T12, L1, L3, L4
deep cardiac pain is:
a) dull and poorly localised
b) dull and well localised
c) sharp and poorly localised
d) sharp and well localised
a
true or false: flow autoregulation is the local regulation of vessel daimeter, indepenent of signals from the CNS or hormones. this response prevents too much blood flowing through a region
true
True or false: mycobacterium tuberculosis is bacillus shaped and requires acid-fast staining to visualise
true
apart from blood loss, what is another cause of low stroke volume shock?
shift of plasma into the tissues –> loss of interstitial fluid (burns)
true or false: the right atrium is smooth
true
how many pulmonary veins drain into the left atrium?
4
true or false: in response to shock, the endocrine system predominates over the nervous system
false
fossa ovalis is found in the:
a) right atrium
b) right ventricle
c) left atrium
d) left ventricle
a)
which statement is false?
a) the longer the vessel, the slower the blood flow
b) blood closest to the vessel wall will experience the most resistance and thus the velocity at those points is lower
c) the smaller the the diameter of the vessel, the greater the proportion of the blood that experiences the most resistance and thus there is a reduced flow rate
d) none of the above are false
d
The lub sound is caused by:
a) semilunar valves opening
b) semilunar valves closing
c) AV valves opening
d) AV valves closing
d) (isovolumetric contraction)
during ventricular filling (mid-to-late diastole), the semilunar valves are open/closed
closed
which two organs have a local buffering response to autoregulate blood flow?
kidneys and brain
septic shock is caused by:
a) either low stroke volume or reduced total peripheral resistance due to sepsis
b) low stroke volume due to sepsis
c) increased system-wide vasodilation and reduced total peripheral resistance
d) loss of interstitial fluid and reduced total peripheral resistance
c
the common carotid artery splits into the internal and external carotid arteries at:
a) superior to clavicle
b) approximately 2cm under the manidibular
c) origin of laryngeal nerve (C2)
d) thyroid cartilage (C4)
d
