BLD 204 EXAM 3 QUESTIONS AND ANSWERS WITH
COMPLETE SOLUTIONS GRADED A++
Repeated thrombi blocking coronary arteries
Which of the following would have the most serious clinical significance?
Activate platelet aggregation
Which of the following is a function of thrombosis
Causing endothelial injury
Which of the following is a way that turbulent blood flow can promote thrombosis?
Plasmin
(Degrades fibrin)
What molecule cleaves fibrin to dissolve clots?
1. Vasoconstriction
2. Platelet Plug
3. Coagulation Cascade
4. Secondary Hemostasis
,(Stable clot formation)
(Thrombin: Cleaves Fibrinogen → Fibrin Clot AND Activates Platelets to reinforce
plug)
5. Limitation of Clotting
(Fibrinolysis, TTPA, Plasminogen → Plasmin)
5 major components involved in hemostasis
hypovolemic
Type of shock caused by a large internal hemorrhage would be
Platelet aggregation
(follows platelet activation, binding of fibrinogen)
Which of the following happens as part of primary homeostasis
Activation
During what step of platelet plug formation do platelets change shape
Activation of the RAA system
Cardiac edema is related to ineffective pumping of the heart, but it is even more strongly
influenced by what?
Increased vascular permeability
Jim has an allergic reaction to a new type of sterile gloves used in his lab. thankfully,
only his hands are affected, but they are very swollen. what is the cause of this localized
edema?
Progressive
, At what stage of shock do metabolic problems emerge?
CRP
In the biochemical theory of fat embolism formation, what molecule causes the smaller
fatty acids to accumulate into larger globules?
true
T/F: ischemia causes infarcts
Thrombi
(make up emboli)
Most clinically significant pulmonary embolism is cause by...?
lipid debris
What is found in the core of atherosclerotic plaque?
thin cap, large core
Which of the following would describe a vulnerable atheroma?
Accumulation of lipoproteins in intima
Which occurs FIRST in the development of an atherosclerotic plaque?
Atherosclerosis
__________is a chronic inflammatory response to endothelial injury
- tiny (1-2 mm) hemorrhages into skin, mucous membranes, or serosal surfaces,
- causes include low platelet counts, defective platelet function, and loss of
vascular wall support, vitamin C deficiency
Petechiae
