51. The end point of the test ‘clotting time’ is the formation of

52. The following are known pro coagulants, EXCEPT

Thrombomodulin

B. Thrombin

C. Plasminogen-activator-Inhibitors

D. Fibrin

54. The RBCs of patients with Megaloblastic anemia will appear as

Spherical and hyperchromic

Macrocytic

C. Crenated and microcytic

Microcytic and hypochromic

55. The Rh negative person

Will naturally have anti-Rh immunoglobulins

Can receive Rh+ donor blood liberally

Has the D antigen on his red cells

Can donate freely to Rh+ person

None of the above

Actually walang nakahighlight dito sa ratio natin --- pero feeling ko tama yung sagot ko dito

57. This molecule forms covalent bonds between fibrin molecules and strengthens the fibrin mesh

Factor IV

Fibrin stabilizing Factor

Plasminogen

Inhibitor of Tpa

58. This molecule is responsible for maintaining the intravascular oncotic pressure

Alpha globulin

Gamma globulin

Albumin

Beta globulin

59. This type of crossmatching is done when recipient’s red cells are tested against the donor’s plasma

Major

Minor

Yna im not sure about this --- huhu---- tell me ano sagot mo dito ah

60. To maintain blood in a fluid state, the blood vessels need to have

Smooth, undamaged endothelial lining

Glycocalyx that repels platelets and clotting factors

Thrombomodulin

All of the above

61. HAHA -- SELECT ONE LANG DAW EH --- WALANG QUESTIONS

Maternal B cells immediately differentiate to plasma cells upon exposure to the injected immunoglobulin

Maternal MHC-II complexes are up-regulated by the anti-Rh immunoglobulin

. The immunoglobulins attack maternal T-cells so that these T-cells cannot mount an immune response

Fetal red cells are destroyed immediately by the anti-Rh immunoglobulins limiting maternal immune response

62. True of regulation of iron absorption

Decreased apotransferrin secretion in bile follows increased body iron stores

Low body iron stores would prompt reduction in apotransferrin secretion in the bile

The regulation of absorption of intravenous Iron is as effective as that of oral / enteral iron

Hemochromatosis is more commonly observed after oral megadoses of iron supplementation

63. True statement/s about platelets

Platelets attach to the Von Willebrand molecule exposed by endothelial damage via GP IIB-IIIA receptors

Platelets attach to other platelets via GP IB and fibrinogen

The nuclei of platelets respond to activation by transcribing genes for thromboxane

Platelets activate nearby platelets via Platelet Activating Factor (PAF)

65. Which of the following is expected to have the highest hematocrit level?

Iron deficient patients

Patients with emphysema

Patients with renal failure

Thalassemia patient

The following can be found in patients with Liver Cirrhosis
