1. Question: Which cell type is responsible for direct targeting and

destruction of infected cells during an immune response?

Answer: Cytotoxic T cells (CD8+ T cells) are responsible for the direct

targeting and destruction of infected cells. They specifically recognize and

kill cells expressing foreign or abnormal antigens.

Rationale: Understanding the role of cytotoxic T cells is crucial for

nursing students as it helps them comprehend the mechanisms by which

the immune system eliminates pathogens and infected cells.

2. Question: What is the main function of B cells during an immune

response?

Answer: B cells produce antibodies that specifically bind and neutralize

foreign substances (antigens), thereby helping to eliminate pathogens and

prevent future infections.

Rationale: Nursing students should have a solid understanding of B cells

and their role in antibody-mediated immunity, as this is essential

knowledge for managing infectious diseases and administering vaccines.

3. Question: Which molecule plays a key role in presenting antigens to

helper T cells and activating immune responses?

Answer: Major Histocompatibility Complex (MHC) class II molecules are

responsible for presenting antigens to helper T cells, initiating a immune

response.

Rationale: Understanding the role of MHC class II molecules is crucial for

nursing students to comprehend the process of antigen presentation and

subsequent immune activation, which is relevant in diagnosing and

treating immune disorders.
