Understanding HIV and Antiretroviral Treatments

What is the initial step in the HIV infection process?

• HIV is destroyed by the immune system

• HIV fuses with the CD4 cell

• HIV becomes inactive

• HIV replicates outside the cell

What is the primary goal of antiretroviral medications?

• To eliminate all infected cells

• To increase the number of CD4 cells

• To reduce the viral load to undetectable levels

• To completely cure HIV

Why is it important to use multiple types of antiretroviral drugs in treatment?

• To prevent the virus from becoming resistant

• To make the treatment more complex

• To reduce side effects

• To increase the cost of treatment

What is the role of fusion inhibitors in HIV treatment?

• They enhance immune response

• They prevent HIV from replicating

• They destroy HIV particles

• They block HIV from entering CD4 cells

How do CCR5 antagonists help in HIV treatment?

• By increasing CD4 cell count

• By destroying HIV particles

• By blocking a protein necessary for HIV entry

• By enhancing the immune system

What is the function of nucleoside reverse transcriptase inhibitors (NRTIs)?

• They integrate viral DNA into host DNA

• They enhance viral replication

• They act as decoy nucleosides to block DNA synthesis

• They destroy viral RNA

How do non-nucleoside reverse transcriptase inhibitors (NNRTIs) work?

• By blocking the enzyme reverse transcriptase

• By enhancing viral replication

• By destroying viral RNA

• By integrating viral DNA into host DNA

What is the role of integrase inhibitors in HIV treatment?

• They increase CD4 cell count

• They destroy viral RNA

• They enhance viral replication

• They prevent viral DNA from integrating into host DNA

What is the function of protease inhibitors in the treatment of HIV?

• They enhance viral replication

• They destroy viral RNA

• They prevent the maturation of viral particles

• They integrate viral DNA into host DNA

What is the overall effect of using a combination of antiretroviral drugs?

• It increases the viral load

• It minimizes HIV replication

• It enhances viral mutation

• It reduces CD4 cell count
