Blood Coagulation Abnormalities and Circulatory Disturbances
**ANSWERS IN BOLD**
1. A 5-year-old male child has a bleeding disease that is characterized by areas
of hemorrhage in the joints and muscles after minor injuries. Lab tests reveal
a deficiency of a coagulation factor active in the early phase of blood
coagulation. What is the most likely diagnosis? Hemophilia
2. Many blood coagulation factors are produced in the liver, and their
concentrations in the blood are reduced in patients with liver disease. True
3. Coagulation factors restrict the clotting process to a limited area. False
4. Polymerized fibrin monomer molecules are joined end to end. True
5. Von Willebrand factor is required for platelets to adhere at the site of a
vascular injury. True
6. Petechiae are small pinpoint areas of bleeding in the skin and deeper tissues
resulting from leakage of blood through minute defects in the capillary
endothelium.
7. Estrogen in oral contraceptives may lead to venous and arterial thrombosis
because estrogen stimulates synthesis of coagulation factors.
8. Several tests are helpful when attempting to establish a diagnosis of a
pulmonary embolism or pulmonary infarct. Which of the following test
would not be helpful? Urine analysis
9. In phase 3 of the blood coagulation process, fibrinogen is converted in
fibrin.
10. Blood plasma contains several different proteins, called coagulation factors,
which, when activated, interact to produce a blood clot.
