Question 1

A patient has a Type IV hypersensitivity (delayed-type hypersensitivity) response to an infection. The nurse understands that which two types of cells are necessary for this response?&#10;A) Antigen-presenting cells and mast cells&#10;B) Cytolytic T lymphocytes and target cells&#10;C) Immunoglobulin cells and dendritic cells&#10;D) Infected macrophages and CD4 helper T cells

Accepted Answer

Infected macrophages and CD4 helper T cells

Question 2

A nurse is teaching a nursing student about a specific acquired immunity system. Which statement by the student indicates a need for further teaching?&#10;A) &#34;Cell-mediated immunity and humoral immunity are both types of specific acquired immune responses.&#34;&#10;B) &#34;Each exposure to an antigen causes a faster, more intense response.&#34;&#10;C) &#34;Immune responses occur only after exposure to a foreign substance.&#34;&#10;D) &#34;The skin is a factor in specific acquired immunity.&#34;

Accepted Answer

&#34;The skin is a factor in specific acquired immunity.&#34;

Question 3

A nurse is discussing the role of antibodies in the complement system with a group of nursing students. Which statement by a student is correct?&#10;A) &#34;Antibodies activate the complement cascade by turning on the alternative pathway.&#34;&#10;B) &#34;Antibodies that are free in solution can activate the complement system.&#34;&#10;C) &#34;Antibodies flag target cells to be lysed by membrane attack complexes.&#34;&#10;D) &#34;Antibody receptors are nonspecific to antigenic determinants.&#34;

Accepted Answer

&#34;Antibodies flag target cells to be lysed by membrane attack complexes.&#34;

Question 4

A patient who breast-feeds her infant asks the nurse about the immunity the infant receives from breast milk. What does the nurse tell the patient about immunity through breast-feeding?&#10;A) &#34;The immunity protects the infant from hypersensitivity reactions.&#34;&#10;B) &#34;The immunity provides phagocytes to help the infant fight infections.&#34;&#10;C) &#34;The immunity results from the transfer of IgA through the breast milk.&#34;&#10;D) &#34;The immunity protects the infant from respiratory and gastrointestinal (GI) microbes.&#34;

Accepted Answer

The answer of A patient who breast-feeds her infant asks...

Question 5

Which statement is true about helper T cells?&#10;A) They are useful but are not essential to immune responses.&#10;B) They do not play a role in antibody production.&#10;C) They have highly specific receptors to antigens on their surface.&#10;D) They prevent CD4 molecules from attaching to antigens.

Question 6

Which immune responses can result in harm to the body?&#10;A) Activation of the complement system&#10;B) Autoimmune response&#10;C) IgE binding to mast cells and basophils&#10;D) Opsonization&#10;E) Recognition of MHC molecules as nonself

Question 7

A nurse is reviewing the immune system with a group of nursing students. One student asks about the difference between cell-mediated immunity and humoral immunity. What should the nurse reply?&#10;A) &#34;Humoral immunity does not involve helper T cells in the immune response.&#34;&#10;B) &#34;Humoral immunity does not have a role in hypersensitivity reactions.&#34;&#10;C) &#34;Humoral immunity requires cytolytic T cells that attack antigens directly.&#34;&#10;D) &#34;Humoral immunity uses cells produced by B lymphocytes in the immune response.&#34;

Accepted Answer

Question 8

A nurse is teaching a group of nursing students about immunoglobulins. Which statement by a student indicates a need for further teaching?&#10;A) &#34;IgD provides a first line of defense against microbes entering the body through the lungs.&#34;&#10;B) &#34;IgE plays a role in hypersensitivity reactions and responses to parasites.&#34;&#10;C) &#34;IgG and IgM participate in the complement response to promote target cell lysis.&#34;&#10;D) &#34;Neonatal immunity is the result of IgG crossing the placenta.&#34;

Question 9

A nurse is teaching a group of nursing students about antibodies. The nurse correctly explains that which type of response is triggered when antigens bind to antibodies on mast cells or basophils?&#10;A) Acquired immune response&#10;B) Autoimmune response&#10;C) Hypersensitivity reaction&#10;D) Transplant rejection
