NURS 301 - Immunology Exam Questions with Correct Answers Graded A+
What are the three functions of the immune system? - Answers Homeostasis, defense, surveillance
What are haptens? What is an example? - Answers Substances within human body that are harmless by
themselves, but can bind to a protein in the body to become an antigen; penicillin allergy
What are the various types of lymphocytes? - Answers B, T (cytotoxic and helper), natural killer cells
What is the function of CD4? - Answers Helps CD8 and NK cells; makes other cells more "robust"
What is CD4? - Answers Helper T cells
What is CD8? - Answers Cytotoxic T cells
What is the function of dendritic cells? - Answers Capture antigens and carry them into the B and T
systems
What are the two types of acquired immunity? - Answers Active and passive
What are the two types of immunity? - Answers Innate and acquired
Which type of immunity exists without prior exposure with an antigen? - Answers Innate
Which components does innate immunity include? - Answers Natural barriers (skin, mucous
membranes), inflammatory response
Does innate immunity have any specificity? - Answers No
Which type of immunity is temporary? - Answers Passive acquired
What is passive acquired immunity? - Answers Process by which the body receives specific antibodies
instead of making them
In which type of immunity does the body receive specific antibodies instead of making them? - Answers
Passive acquired
Does passive acquired immunity produce memory cells? - Answers No
Why is passive acquired immunity temporary? - Answers No memory cells are produced
What are examples of passive acquired immunity? - Answers Immunoglobulin from mother to baby,
injection of serum antibodies, antivenom
Immunoglobulins passed from the mother to the baby through placenta or breast milk is which type of
immunity? - Answers Passive acquired
What is active acquired immunity? - Answers Process that occurs when body responds to the presence
of a pathologic organism and produces antibodies against them
, In which type of immunity does the body respond to the presence of a pathologic organism and produce
antibodies against them? - Answers Active acquired
When does active acquired immunity occur? - Answers Following an invasion of antigen
Which type of immunity follows an invasion of an antigen and results in sensitized antibodies? - Answers
Active acquired
Which type of immunity produces memory cells? - Answers Active acquired
Does active acquired immunity produce memory cells? - Answers Yes
With active acquired immunity, what happens when the body is reinvaded by an organism? - Answers
Responds faster than before
What are examples of active acquired immunity? - Answers Vaccines, having an illness to produce
antibodies against it
Vaccines/immunization is an example of which type of immunity? - Answers Active acquired
What are the two types of immune responses? - Answers Humoral and cell-mediated
Does humoral immunity produce memory cells? - Answers Yes
Does cell-mediated immunity produce memory cells? - Answers Yes
What occurs with humoral immunity? - Answers An antigen invades and causes B cells to divide and
become plasma cells which produce antibodies that travel in the bloodstream to communicate with
other cells
What is the main cell involved in humoral immunity? - Answers B cells that become plasma cells
How longs does the humoral response take after initial exposure? - Answers 4-8 days
How longs does the humoral response take after the 2nd exposure? - Answers 1-3 days
What is the initial immunoglobulin involved in humoral immunity? - Answers IgM
Describe the involvement of immunoglobulins in humoral immunity during the initial exposure and
subsequent exposures - Answers Initial: IgM is high amounts, then IgG
Subsequent: IgM levels stay the same, IgG skyrockets
Which two immunoglobulins are primarily involved in humoral immunity? - Answers IgM and IgG
Is IgM specific? Does it produce memory cells? - Answers No; no
Is IgG specific? Does it produce memory cells? - Answers Yes; yes
