QUESTIONS WITH ACCURATE
SOLUTIONS
1) Hypovolemic shock may be caused by: -- Answer ✔✔ severe
vomiting and diarrhea
2) The intrinsic clotting mechanism is initiated by: -- Answer ✔✔
activation of factor XII by surface contact
3) _____ , released in heart failure, causes increased sodium resorption
in kidneys, leading to increased sodium and _____ retention. --
Answer ✔✔ aldosterone
water
4) Localized edema could be caused by: -- Answer ✔✔ lymphatic
obstruction
5) Diabetics may develop degenerative changes in the vasculature.
Diminished blood supply to the extremities and subsequent
infarction could lead to the development of: -- Answer ✔✔ gangrene
,6) The end result of the clotting (coagulation) mechanism is: -- Answer
✔✔ the formation of insoluble strands of fibrin, which form the
framework of the blood clot
7) Lymphatic obstruction will eventually lead to: -- Answer ✔✔ fibrosis
of the affected area
8) A person or animal in left-sided heart failure may show which of the
following?
a) hepatic congestion
b) shortness of breath and coughing
c) systemic venous congestion -- Answer ✔✔ b) shortness of
breath and coughing
9) Formation of the primary hemostatic plug results from: -- Answer
✔✔ platelet aggregation
10) Small petechial hemorrhages are most likely the result of:
a) low platelet numbers
b) deficiency of coagulation factors
c) DIC -- Answer ✔✔ a) low platelet numbers
11) With vascular injury, platelets are exposed to the extracellular
matrix, which induces platelet adhesion via interactions with: --
Answer ✔✔ von Willebrand factor
12) Emboli originating from deep venous thromboses in the legs will
likely become lodged in the: -- Answer ✔✔ pulmonary circulation
, 13) A large thrombus has developed in the renal artery. If portions of
this thrombus were to break free and embolize, infarcts could occur
in the: -- Answer ✔✔ kidney
14) Shock can lead to disseminated intravascular coagulation
because: -- Answer ✔✔ hypoxic endothelial injury can initiate
microthrombosis
15) Transient arteriolar vasoconstriction in early hemostasis is
primarily due to: -- Answer ✔✔ reflex neurogenic mechanisms
16) A localized area of necrosis resulting from inadequate blood
supply to tissues is termed: -- Answer ✔✔ infarction
17) A common initiating mechanism of disseminated intravascular
coagulation (DIC) is: -- Answer ✔✔ widespread endothelial injury
18) Shock becomes irreversible shock when: -- Answer ✔✔ metabolic
acidosis furthers injury to cells, so they can no longer produce
energy
19) Shock, whatever its cause, is characterized by: -- Answer ✔✔
generalized reduction in tissue perfusion
20) Ischemia refers to: -- Answer ✔✔ a reduction or failure of blood
supply to tissues
