Which plays a critical role in HIV and are responsible for the release of cytokines?
- A.
Helper T cells
- B.
Memory Cells
- C.
B Cells
- D.
None of the above
Correct Answer
A. Helper T cellsExplanation
Helper T cells play a critical role in HIV and are responsible for the release of cytokines. Cytokines are small proteins that are involved in cell signaling and immune response regulation. In the context of HIV, helper T cells are specifically targeted and destroyed by the virus, leading to a weakened immune system. These cells are crucial for coordinating the immune response and activating other immune cells, including B cells and cytotoxic T cells, to fight against infections. Therefore, the release of cytokines by helper T cells is essential for the immune system's proper functioning in HIV.Rate this question:
-
- 18.
Memory T cells are produced by the activation of cytotoxic and helper T cells and suppressor T cells dampen the responses of T cells and B cells.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Memory T cells are indeed produced by the activation of cytotoxic and helper T cells. Memory T cells are a type of T cell that are formed during an immune response and are responsible for maintaining immunological memory. They are able to quickly recognize and respond to pathogens that the body has previously encountered. On the other hand, suppressor T cells, also known as regulatory T cells, play a role in dampening the immune response by suppressing the activity of other T cells and B cells. Therefore, the statement that memory T cells are produced by the activation of cytotoxic and helper T cells is true.Rate this question:

B cells come from the bone marrow and differentiate into
- A.
T cells
- B.
Cytotoxic cells
- C.
Plasma cells
- D.
None of the above
Correct Answer
C. Plasma cellsExplanation
B cells are a type of white blood cell that originate in the bone marrow. They have the ability to differentiate into various cell types. In this case, B cells can differentiate into plasma cells. Plasma cells are responsible for producing and secreting antibodies, which play a crucial role in the immune response. Therefore, the correct answer is plasma cells.Rate this question:

B-cells produce antibodies after being stimulated by helper T cells.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
B-cells are a type of white blood cell that plays a crucial role in the immune response. When B-cells encounter a foreign substance, such as a pathogen, they need to be stimulated by helper T cells in order to produce antibodies. Helper T cells recognize the antigen presented by B-cells and release chemical signals that activate the B-cells to differentiate into plasma cells. These plasma cells then produce and secrete antibodies specific to the encountered antigen, aiding in the immune response against the pathogen. Therefore, the statement that B-cells produce antibodies after being stimulated by helper T cells is true.Rate this question:

Which of the following best signifies the transition of HIV to AIDS?
- A.
Ruptured helper T's release more HIV
- B.
Lack of antibodies
- C.
HIV invades and damages helper Ts
Correct Answer
B. Lack of antibodiesExplanation
The transition of HIV to AIDS is best signified by the lack of antibodies. As HIV progresses, it attacks and damages the immune system, particularly the helper T cells. These cells play a crucial role in coordinating the immune response and producing antibodies. As the number of helper T cells decreases, the body's ability to produce antibodies diminishes, leading to a weakened immune system and the development of AIDS. Therefore, the absence of antibodies is a significant indicator of the progression from HIV to AIDS.Rate this question:

HAART therapy must be started if CD4 count drops below 350 or symptoms appear.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
HAART therapy, also known as highly active antiretroviral therapy, is a treatment used for HIV/AIDS. It is recommended to start HAART therapy if the CD4 count drops below 350 or if symptoms of the disease appear. This is because a CD4 count below 350 indicates a weakened immune system, making the individual more susceptible to opportunistic infections. Additionally, the presence of symptoms indicates that the disease is progressing and treatment is necessary to control the virus and prevent further complications. Therefore, the statement "HAART therapy must be started if CD4 count drops below 350 or symptoms appear" is true.Rate this question:
-

Which is not a treatment failure of antiretroviral therapy?
- A.
Patient non-adherence to reginem
- B.
Patient non-tolerance of adverse effects
- C.
All of the above
- D.
None of the above
Correct Answer
D. None of the aboveExplanation
The correct answer is "none of the above". This means that both patient non-adherence to the regimen and patient non-tolerance of adverse effects are considered treatment failures of antiretroviral therapy. In other words, if a patient does not adhere to the prescribed medication schedule or cannot tolerate the side effects, it can be considered a failure of the treatment. Therefore, the statement "none of the above" implies that both options mentioned are treatment failures.Rate this question:

HIV is a retrovirus.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
HIV is indeed a retrovirus. Retroviruses are RNA viruses that are able to convert their RNA genome into DNA using the enzyme reverse transcriptase. This DNA is then integrated into the host cell's genome, allowing the virus to replicate and persist in the body. HIV specifically targets and infects immune cells, leading to the progressive weakening of the immune system and the development of AIDS.Rate this question:

All of the above
- E.
None of the above
Correct Answer
D. All of the aboveExplanation
All of the listed drugs, Abacavir (Ziagen), Didanosine (Videx), and Zidovudine (Retrovir), are NRTIs (nucleoside reverse transcriptase inhibitors). NRTIs are a class of antiretroviral drugs used in the treatment of HIV/AIDS. They work by inhibiting the reverse transcriptase enzyme, which is necessary for the replication of the virus. Therefore, all of the listed drugs are NRTIs and can be used in the treatment of HIV/AIDS.Rate this question:

- A.
Lamivudine (Epivir) PO
- B.
Delavirdine (rescriptor)
- C.
Efavirenz (Sustiva)
- D.
None of the above
Correct Answer
A. Lamivudine (Epivir) POExplanation
Lamivudine (Epivir) is not an NNRTI. NNRTIs, or non-nucleoside reverse transcriptase inhibitors, are a class of antiretroviral drugs used to treat HIV/AIDS. Lamivudine, on the other hand, is a nucleoside reverse transcriptase inhibitor (NRTI). NRTIs work by incorporating themselves into the viral DNA chain, preventing further replication of the virus. NNRTIs, on the other hand, bind directly to the reverse transcriptase enzyme, inhibiting its activity. Therefore, Lamivudine does not belong to the NNRTI class of drugs.Rate this question:

- A.
True
- B.
False
Correct Answer
A. TrueExplanation
During the asymptomatic stage of AIDS, individuals infected with the virus may not show any symptoms for a prolonged period, which can last up to several years. This means that even though they are infected, they may not experience any noticeable signs of the disease. It is important to note that although individuals may not have symptoms during this stage, they can still transmit the virus to others. Regular testing and practicing safe behaviors are crucial to prevent the spread of HIV/AIDS.Rate this question:
