#1
Which bodily fluid is primarily responsible for HIV transmission?
Blood
ExplanationBlood is the main carrier of HIV, facilitating transmission through direct contact or sharing of contaminated needles.
#2
What does HIV stand for?
Human Immunodeficiency Virus
ExplanationHIV stands for Human Immunodeficiency Virus, the virus that causes AIDS by attacking the body's immune system.
#3
Which population group is most affected by HIV/AIDS globally?
Adolescents and young adults
ExplanationAdolescents and young adults are disproportionately affected by HIV/AIDS globally due to factors such as risky behavior, lack of access to prevention measures, and social stigma.
#4
What is the main function of CD4 cells in the immune system?
Activating T cells
ExplanationCD4 cells play a crucial role in the immune system by activating other immune cells, particularly T cells, to mount an effective response against pathogens, including viruses like HIV.
#5
Which of the following is a common opportunistic infection associated with advanced HIV/AIDS?
Pneumocystis pneumonia
ExplanationPneumocystis pneumonia is a common opportunistic infection that occurs in individuals with advanced HIV/AIDS due to their weakened immune systems, leading to severe respiratory problems.
#6
What is the most effective way to prevent sexual transmission of HIV?
Using condoms consistently and correctly
ExplanationConsistent and correct use of condoms during sexual intercourse is the most effective way to prevent the sexual transmission of HIV, reducing the risk significantly.
#7
Which of the following is NOT a common way HIV can be transmitted?
Mosquito bites
ExplanationHIV cannot be transmitted through mosquito bites as the virus cannot survive in insects' bodies or be transmitted through their bites.
#8
What does AIDS stand for?
Acquired Immune Deficiency Syndrome
ExplanationAIDS stands for Acquired Immune Deficiency Syndrome, a condition caused by HIV where the immune system is severely damaged, making the body susceptible to opportunistic infections and cancers.
#9
Which bodily fluid has the highest concentration of HIV?
Semen
ExplanationSemen has the highest concentration of HIV among bodily fluids, making unprotected sexual intercourse a significant mode of transmission.
#10
What is the term for the period of time between HIV infection and the development of detectable antibodies?
Incubation period
ExplanationThe incubation period refers to the time between HIV infection and the appearance of detectable antibodies in the bloodstream, typically ranging from a few weeks to several months.
#11
Which organ does HIV primarily target and damage in the human body?
Immune system
ExplanationHIV primarily targets and damages the immune system, specifically CD4 cells, weakening the body's ability to fight infections and diseases.
#12
What is the recommended approach for HIV testing in pregnant women?
Testing during prenatal care with repeat testing in the third trimester
ExplanationPregnant women should be tested for HIV during prenatal care with repeat testing in the third trimester to ensure early detection and appropriate interventions to prevent mother-to-child transmission.
#13
Which antiretroviral therapy (ART) medication is often used to prevent HIV transmission from mother to child during childbirth?
AZT (Zidovudine)
ExplanationAZT (Zidovudine) is commonly used in preventing mother-to-child transmission of HIV during childbirth, reducing the risk of transmission to the newborn.
#14
Which HIV test is commonly used for rapid screening but requires confirmation with a second test?
Rapid antibody test
ExplanationRapid antibody tests provide quick results but may yield false positives, requiring confirmation with a second, more specific test to confirm HIV infection.
#15
Which antiretroviral medication is known for its potential side effects like lipodystrophy and metabolic abnormalities?
Lopinavir
ExplanationLopinavir, a protease inhibitor, is associated with side effects such as lipodystrophy (abnormal fat distribution) and metabolic abnormalities, which can affect the long-term health of HIV-positive individuals on treatment.
#16
Which of the following is a common symptom of acute HIV infection?
Rash
ExplanationA rash is a common symptom of acute HIV infection, typically appearing within 2-6 weeks after exposure to the virus, often accompanied by other flu-like symptoms such as fever, sore throat, and fatigue.
#17
Which antiretroviral medication is a protease inhibitor commonly used in HIV treatment regimens?
Lopinavir
ExplanationLopinavir is a protease inhibitor commonly used in combination with other antiretroviral medications as part of HIV treatment regimens to suppress the replication of the virus, reducing HIV-related complications and improving the quality of life for HIV-positive individuals.
