Module 1: Blood
Q1: Which of the following formed elements is responsible for transporting oxygen and contains
the protein hemoglobin?
A. Leukocytes
B. Thrombocytes
C. Erythrocytes
D. Plasma proteins
Correct Answer: C
Rationale: Erythrocytes, or red blood cells, are the primary carriers of oxygen because they
contain hemoglobin, which binds to oxygen molecules in the lungs.
Q2: A patient has a differential white blood cell count showing elevated levels of neutrophils.
Which physiological process is most likely occurring?
A. A parasitic infection
B. An acute bacterial infection
C. A viral infection
D. An allergic reaction
Correct Answer: B
Rationale: Neutrophils are the first responders to bacterial infections; their numbers typically rise
sharply during the acute phase of such an infection to phagocytose pathogens.
Q3: During hemostasis, vascular spasm occurs immediately after injury. What is the primary
purpose of this vasoconstriction?
A. To allow platelets to adhere more easily
,2
B. To reduce blood loss and give clotting mechanisms time to work
C. To increase blood flow to the area for healing
D. To release tissue factor (Factor III)
Correct Answer: B
Rationale: Vascular spasms constrict the damaged vessel, which immediately decreases blood
flow through the injury site, minimizing blood loss while the platelet plug and coagulation
cascade form.
Q4: Which clotting factor is stabilized by Vitamin K and is essential for the synthesis of several
other clotting factors in the liver?
A. Factor I (Fibrinogen)
B. Factor II (Prothrombin)
C. Factor VIII (Antihemophilic factor)
D. Factor XIII (Fibrin-stabilizing factor)
Correct Answer: B
Rationale: Vitamin K is a necessary cofactor for the liver's production of prothrombin (Factor II)
and other factors (VII, IX, X); without it, clotting time is significantly prolonged.
Q5: A patient with blood type A, Rh-negative receives a transfusion of blood type B, Rh-positive.
What will happen in the patient's body?
A. The anti-A antibodies in the donor blood will attack the recipient's RBCs.
B. The recipient's anti-B antibodies will attack the donor RBCs.
C. The recipient's anti-Rh antibodies will attack the donor RBCs immediately.
D. No reaction will occur because the donor is the universal donor.
Correct Answer: B
Rationale: A person with type A blood naturally has anti-B antibodies; when type B blood is
introduced, these antibodies bind to the foreign B antigens on the donor red blood cells, causing
agglutination and hemolysis.

Q6: Which of the following scenarios describes a positive-feedback mechanism involved in
hemostasis?
A. Fibrinolysis dissolving the clot
B. Platelet releasing chemicals to attract more platelets
C. Constriction of the vessel stopping blood loss
D. The liver producing clotting factors
Correct Answer: B
Rationale: Platelet aggregation is an example of positive feedback; once platelets start to stick,
they release chemical signals like ADP and thromboxane A2 that attract and activate even more
platelets to the site.
Q7: A patient is diagnosed with iron-deficiency anemia. How will this affect the appearance of
their red blood cells under a microscope?
A. They will appear larger than normal (macrocytosis).
B. They will appear smaller than normal and pale (microcytic hypochromic).
C. They will have a sickle shape.
D. They will be fragmented (schistocytes).
Correct Answer: B
Rationale: Iron is essential for hemoglobin synthesis; a deficiency leads to smaller (microcytic)
and paler (hypochromic) red blood cells because there is less hemoglobin to fill the cell.
Q8: Which white blood cell type is characterized by a bilobed nucleus and dark granules that
stain red, and is known to mediate allergic reactions and attack parasitic worms?
A. Basophil
B. Eosinophil
C. Lymphocyte
D. Monocyte
Correct Answer: B
, 4
Rationale: Eosinophils have a distinct bilobed nucleus and red-orange granules; they are crucial
for mounting an immune response against parasitic infections and modulating allergic
inflammation.
Q9: In the intrinsic pathway of coagulation, the process is initiated by:
A. Trauma to the blood vessel wall or exposure to collagen
B. Release of tissue factor (thromboplastin) from damaged tissues
C. Conversion of prothrombin to thrombin
D. Activation of Factor VII
Correct Answer: A
Rationale: The intrinsic pathway is triggered by trauma inside the vascular system, specifically
when blood contacts exposed collagen or negatively charged surfaces beneath the endothelium.
Q10: What is the function of plasmin in the circulatory system?
A. To activate platelets
B. To dissolve fibrin clots
C. To stimulate the bone marrow
D. To produce antibodies
Correct Answer: B
Rationale: Plasmin is an enzyme that acts as a "clot buster," digesting fibrin strands to break
down the clot once tissue repair has begun, a process known as fibrinolysis.
Q11: A patient's chart indicates they are Rh-negative. Why is Rho(D) immune globulin
(RhoGAM) administered during pregnancy?
A. To stimulate the production of anti-Rh antibodies
B. To destroy the mother's existing antibodies
C. To prevent the mother from forming anti-Rh antibodies against fetal RBCs
D. To increase the fetal blood volume
Correct Answer: C
