A) Red blood cells
B) Platelets
C) B and T lymphocytes
D) Neutrophils only
Answer: C
,Explanation: Ig therapy influences the activity of B and T lymphocytes, altering immune responses and
providing therapeutic benefits.
Question 6: In the context of immunoglobulin therapy, what does “passive immunization” mean?
A) Stimulating the patient’s own immune response
B) Providing pre-formed antibodies to the patient
C) Vaccinating with a live virus
D) Using chemotherapy to suppress the immune system
Answer: B
Explanation: Passive immunization involves administering pre-formed antibodies, offering immediate
but temporary protection.
Question 7: What is the role of immunoglobulin therapy in autoimmune conditions?
A) To completely cure the disease
B) To modulate the immune system and reduce inflammation
C) To replace all immune cells
D) To stimulate antibody production excessively
Answer: B
Explanation: In autoimmune disorders, Ig therapy helps to modulate the immune response and reduce
harmful inflammation.
Question 8: Which statement accurately reflects the history of Ig therapy?
A) It was first used for organ transplants
B) Its use began with the treatment of diphtheria
C) It has always been used only in immunodeficient patients
D) It was developed solely for cancer patients
Answer: B
Explanation: Ig therapy’s early use was in the treatment of infectious diseases like diphtheria, providing
critical passive immunity.
Question 9: How does immunoglobulin therapy help patients with primary immunodeficiency?
A) By directly increasing the number of T-cells
B) By supplying the antibodies that their body cannot produce
C) By eliminating all pathogens from the body
D) By blocking immune cell receptors
Answer: B
Explanation: In primary immunodeficiency, patients lack adequate antibody production, and Ig therapy
supplies the missing antibodies to protect against infections.
Question 10: What distinguishes immunoglobulin therapy from traditional vaccine administration?
A) It induces long-term immunity
B) It provides immediate passive immunity rather than long-term active immunity
C) It is administered orally
D) It requires repeated dosing for lasting effects
Answer: B
Explanation: Unlike vaccines that induce the body to produce its own antibodies (active immunity),
immunoglobulin therapy provides immediate but temporary passive immunity.
,Question 11: Which of the following is a key benefit of immunoglobulin therapy in managing
autoimmune disorders?
A) Complete suppression of the immune system
B) Rapid reversal of immune-mediated damage
C) Enhancement of T-cell activity
D) Permanent cure of the disease
Answer: B
Explanation: Immunoglobulin therapy can quickly reduce immune-mediated damage by neutralizing
autoantibodies and modulating immune cell functions.
Question 12: What historical milestone is associated with the early use of Ig therapy?
A) The discovery of penicillin
B) The development of blood transfusions
C) The initial use in treating immune deficiencies in the mid-20th century
D) The invention of monoclonal antibodies
Answer: C
Explanation: The mid-20th century marked a significant period when immunoglobulin therapy was first
applied to treat immune deficiencies.
Question 13: Which process is primarily responsible for the purification of immunoglobulin products?
A) Centrifugation and filtration
B) Chromatography and viral inactivation
C) Chemical synthesis
D) Genetic engineering
Answer: B
Explanation: Modern immunoglobulin products are purified using chromatography techniques and viral
inactivation methods to ensure safety and efficacy.
Question 14: Immunoglobulin therapy can be used as adjunctive treatment in which of the following
scenarios?
A) Severe bacterial infections unresponsive to antibiotics
B) Mild seasonal allergies only
C) Exclusively nutritional deficiencies
D) All forms of viral infections
Answer: A
Explanation: In some cases, Ig therapy is used as an adjunct to antibiotics in severe infections,
particularly when the patient is immunocompromised.
Question 15: What is the primary function of antibodies provided in immunoglobulin therapy?
A) To directly kill bacteria
B) To mark pathogens for destruction by the immune system
C) To increase blood clotting
D) To transform into immune cells
Answer: B
Explanation: The antibodies in Ig therapy bind to pathogens, marking them for clearance by other
components of the immune system.
, Question 16: In terms of molecular structure, immunoglobulins are best described as what?
A) Lipids
B) Carbohydrates
C) Proteins with specific antigen-binding sites
D) Nucleic acids
Answer: C
Explanation: Immunoglobulins are proteins that have unique antigen-binding sites, allowing them to
recognize and bind to specific antigens.
Question 17: What role do Fc receptors play in the function of immunoglobulin therapy?
A) They degrade the antibodies
B) They mediate the clearance of immune complexes
C) They produce antibodies
D) They inhibit antibody activity
Answer: B
Explanation: Fc receptors on immune cells bind to the constant region of antibodies, facilitating the
clearance of pathogens and immune complexes.
Question 18: Which of the following is a potential immunomodulatory effect of Ig therapy in
autoimmune diseases?
A) Enhancement of B-cell autoantibody production
B) Inhibition of complement activation
