The nurse is preparing a teaching plan for a group of well-educated clients who were found to be HIV positive within the last year. The nurse should explain that the human immunodeficiency virus (HIV) acts in which way to suppress the immune system?
Increase in B-lymphocytes and IgM.
Destruction of helper T-cells and CD4 cells.
Deficiency of cytotoxic T cells.
Proliferation of suppressor T-cells.
The Correct Answer is B
Choice A rationale
An increase in B-lymphocytes and IgM is not how HIV suppresses the immune system. B-lymphocytes are responsible for producing antibodies, and IgM is a type of antibody. HIV primarily affects T-lymphocytes, specifically helper T-cells (CD4 cells), rather than B-lymphocytes.
Choice B rationale
The destruction of helper T-cells and CD4 cells is the primary mechanism by which HIV suppresses the immune system. HIV targets and infects these cells, leading to their depletion. Helper T-cells play a crucial role in coordinating the immune response, and their loss results in a weakened immune system, making the body more susceptible to infections and diseases.
Choice C rationale
A deficiency of cytotoxic T cells is not the primary mechanism by which HIV suppresses the immune system. Cytotoxic T cells (CD8 cells) are involved in directly killing infected cells, but the main impact of HIV is on helper T-cells (CD4 cells), which are essential for orchestrating the immune response.
Choice D rationale
The proliferation of suppressor T-cells is not how HIV suppresses the immune system. Suppressor T-cells (regulatory T cells) help regulate and control the immune response, but HIV primarily affects helper T-cells (CD4 cells), leading to their destruction and a weakened immune system.

Correct Answer is A
Explanation
Choice A rationale
Isolating the client from others is the most important action to prevent the spread of COVID-19. This includes isolating the client from other clients, family, and healthcare workers not wearing proper PPE2.
Choice B rationale
Reporting the COVID-19 result to the local health department is important but not the immediate priority. Isolation takes precedence to prevent transmission.
Choice C rationale
Teaching the client to wear a mask, hand wash, and social distance is essential but secondary to immediate isolation.
Choice D rationale
Counseling family members to monitor for symptoms is important but not the immediate priority. Isolation of the client is the first step.
Correct Answer is B
Explanation
Choice A rationale
Providing step-by-step verbal directions may not be effective for clients with Huntington’s disease due to their cognitive impairments, which can include forgetfulness, impaired judgment, and difficulty concentrating.
Choice B rationale
Escorting the client to the cafeteria is the best approach as it ensures the client reaches the destination safely. Clients with Huntington’s disease often have unsteady gait and involuntary movements, making it difficult for them to navigate independently.
Choice C rationale
Orienting the client to the color-coding system may not be effective due to the cognitive impairments associated with Huntington’s disease, such as difficulty concentrating and impaired judgment.
Choice D rationale
Using the hospital map to show the client where the cafeteria is located is not practical for clients with Huntington’s disease due to their cognitive impairments, which can include forgetfulness and difficulty concentrating.
