SECTION 1: IMMUNOLOGIC AND BIOLOGIC THERAPIES - Questions 1-10
Q1: TNF Inhibitor Mechanism
The student is reviewing biologic therapies. What is the mechanism of action of infliximab?
A. Monoclonal antibody that binds TNF-alpha and neutralizes its activity
B. Soluble TNF receptor that binds TNF-alpha
C. Interleukin-1 receptor antagonist
D. Inhibitor of T-cell activation
Correct Answer: A
Rationale: Infliximab is a chimeric monoclonal antibody that binds to tumor necrosis factor-alpha
(TNF-α) and neutralizes its pro-inflammatory effects. Etanercept is a soluble TNF receptor fusion
protein. Anakinra is an IL-1 receptor antagonist. Abatacept inhibits T-cell activation. [100% CORRECT]
Q2: TNF Inhibitor Adverse Effect
The student is reviewing biologic therapies. Which serious adverse effect requires screening before
initiating TNF inhibitor therapy?
A. Latent tuberculosis reactivation
B. Hypertension
C. Bradycardia
D. Hyperglycemia
Correct Answer: A
Rationale: TNF inhibitors increase the risk of reactivating latent tuberculosis and other infections.
Patients must be screened for TB with a tuberculin skin test or interferon-gamma release assay
before starting therapy. They can also increase the risk of lymphoma and demyelinating disease.
[100% CORRECT]
Q3: Vaccine Type
The student is reviewing immunizations. Which vaccine is an example of a live attenuated vaccine?
, 2
A. Measles, mumps, rubella (MMR)
B. Hepatitis B
C. Tetanus
D. Influenza (inactivated)
Correct Answer: A
Rationale: MMR is a live attenuated vaccine. Hepatitis B, tetanus, and inactivated influenza are
inactivated or subunit vaccines. Live vaccines are contraindicated in immunocompromised patients.
[100% CORRECT]
Q4: Immunoglobulin Use
The student is reviewing immunologic agents. What is the primary use of intravenous immune
globulin (IVIG)?
A. To provide passive immunity in immunodeficiency or autoimmune conditions
B. To provide active immunity
C. To suppress the immune system
D. To treat bacterial infections
Correct Answer: A
Rationale: IVIG provides passive immunity by supplying antibodies from pooled human plasma. It is
used for primary immunodeficiencies, autoimmune diseases (e.g., ITP, Guillain-Barré), and some
infections. It does not provide active immunity or directly treat bacterial infections. [100% CORRECT]
Q5: Interferon Adverse Effect
The student is reviewing immunomodulators. Which adverse effect is commonly associated with
interferon therapy?
A. Flu-like symptoms
B. Hypertension
C. Bradycardia
D. Hyperglycemia
Correct Answer: A
Rationale: Interferons (e.g., interferon alfa, beta) commonly cause flu-like symptoms such as fever,
chills, myalgia, and fatigue. They can also cause depression, myelosuppression, and hepatotoxicity.
[100% CORRECT]
Q6: Calcineurin Inhibitor Mechanism
The student is reviewing immunosuppressants. What is the mechanism of action of tacrolimus?
A. Inhibits calcineurin, blocking T-cell activation
B. Inhibits purine synthesis
