AIDS Quiz
Questions: 16 · 10 minutes
1. Which statement best describes the relationship between HIV and AIDS?
HIV and AIDS are two names for separate infections transmitted in the same ways.
AIDS is the virus, while HIV is the collection of symptoms it causes.
HIV is the virus; AIDS is the most advanced stage of HIV infection when defined clinical criteria are met.
Every person with HIV immediately has AIDS.
2. Which activity does not transmit HIV?
Sharing a toilet seat with someone who has HIV
Having sex involving relevant body fluids without an effective prevention method
Breastfeeding when HIV is not effectively treated
Sharing injection equipment that contains infected blood
3. A person taking HIV treatment has maintained an undetectable viral load as confirmed through ongoing care. What does U=U mean for sexual transmission?
They are cured and no longer need HIV medication or monitoring.
Transmission is prevented only if neither partner has any symptoms.
Their chance of transmission is reduced, but it remains high during every sexual encounter.
They do not sexually transmit HIV while their viral load remains undetectable.
4. Which group of body fluids can transmit HIV under relevant exposure conditions?
Saliva, tears, sweat, and urine
Blood, semen, vaginal or rectal fluids, and breast milk
Saliva, nasal mucus, vomit, and sweat
Tears, saliva, breast milk, and perspiration
5. Under a commonly used clinical definition, which finding can support an AIDS diagnosis in a person with HIV?
Any fever occurring after a possible exposure
A positive rapid screening test without follow-up testing
Fatigue lasting longer than one month, regardless of other findings
A CD4 count below 200 cells/mm³ or a specified AIDS-defining condition
6. A person receives a negative HIV test 10 days after a possible exposure. What is the safest interpretation?
The test may have been taken during its window period, so they should follow professional guidance about repeat testing.
Every type of HIV test is conclusive 10 days after exposure.
The result is conclusive unless flu-like symptoms appear later.
A negative result that early means the exposure could not transmit HIV.
7. A healthcare worker experiences a needlestick involving potentially infectious blood. What is the best immediate response?
Squeeze the wound repeatedly and decide what to do based on how much it bleeds.
Wash the area with soap and water, report the exposure, and obtain prompt evaluation for PEP.
Take one immediate HIV test and consider the matter settled if it is negative.
Wait for symptoms before reporting the incident.
8. What is an opportunistic infection in the context of advanced HIV?
An infection acquired only through the same exposure that transmitted HIV
A mild reaction that shows HIV treatment has started working
A second strain of HIV that always causes immediate symptoms
An infection that occurs more often or becomes more severe when the immune system is weakened
9. What is pre-exposure prophylaxis, commonly called PrEP?
A vaccine given after an HIV test becomes positive
A short antibiotic course used after any sexual contact
Medicine taken by an HIV-negative person to substantially reduce the chance of acquiring HIV
Treatment used only after a person develops AIDS-defining conditions
10. Which approach most effectively reduces the chance of transmitting HIV during pregnancy, birth, or breastfeeding?
Effective antiretroviral treatment with appropriate medical care and viral-load management
Waiting to begin HIV treatment until after delivery
Using antibiotics throughout pregnancy instead of HIV medicine
Monitoring for symptoms in the baby before making a treatment plan
11. A laboratory HIV screening test is reactive. What generally happens next?
Symptoms are reviewed to decide whether the result counts as positive.
The established testing process uses supplemental follow-up testing to confirm and classify the result.
AIDS is diagnosed immediately from the screening result.
The same screening test is repeated years later before any conclusion is considered.
12. Two partners want to use condoms as part of HIV prevention. Which statement is accurate?
Condoms work only when combined with antibiotics.
Condoms are useful only when one partner has visible symptoms.
Correct and consistent condom use reduces HIV transmission risk and can also help prevent other sexually transmitted infections.
Using two external condoms at once provides better protection than using one correctly.
13. Jordan has fatigue and swollen glands and wonders whether these symptoms prove an HIV infection. What is the most accurate response?
The symptoms are nonspecific; appropriate HIV testing, not symptoms alone, is needed to determine status.
Those symptoms confirm HIV if they continue for more than a week.
HIV can be excluded if there is no rash or fever.
Symptoms can identify HIV accurately if the possible exposure date is known.
14. Lee sometimes injects drugs and wants to reduce the chance of acquiring HIV. Which action directly addresses transmission through injection equipment?
Share equipment only when no blood is visible on it.
Take antibiotics after using equipment that another person handled.
Rinse shared equipment with water immediately before use.
Use new, sterile needles and other injection equipment every time and never share them.
15. Sam learns that a condom broke during a possible HIV exposure about 24 hours ago. Which response is most appropriate?
Wait two weeks to see whether acute symptoms develop.
Take an at-home antibody test immediately and rely on that result.
Seek urgent medical advice about PEP, which must be started within 72 hours and works best as soon as possible.
Begin PrEP at the next routine checkup because timing does not matter.
16. What is true of the fever, sore throat, rash, or fatigue that can occur during early HIV infection?
Their exact combination can reliably distinguish HIV from influenza.
They overlap with many other illnesses, and some people with HIV have no early symptoms.
They appear after every HIV infection and always in the same order.
Their absence rules out HIV after a possible exposure.
