STD Quiz
Questions: 16 · 10 minutes
1. A person with genital herpes has no visible sores. Which statement is accurate?
Transmission can still occur because the virus may shed when no sores are visible.
A negative visual check proves the virus is no longer present.
Transmission is impossible until another sore appears.
The infection can spread only through blood during symptom-free periods.
2. Someone takes an STI test the day after a possible exposure and receives a negative result. Why might follow-up testing still be advised?
Negative results are valid only when symptoms are present.
Every STI test must be repeated monthly for life.
STI tests cannot identify infections before treatment begins.
The infection may still be within a window period when the test cannot reliably detect it.
3. Which is a possible consequence when chlamydia or gonorrhea goes untreated in someone with a uterus and reproductive organs?
Immediate lifelong immunity to the same infection.
Pelvic inflammatory disease, which can contribute to chronic pain, ectopic pregnancy, or infertility.
Guaranteed development of genital warts.
Permanent protection against other bacterial infections.
4. A person takes birth control pills consistently. What protection do the pills provide against STIs?
They prevent most bacterial STIs but not viral ones.
They protect against infections transmitted through genital fluids.
They prevent STIs only when taken at the same time each day.
They help prevent pregnancy but do not protect against STIs.
5. A person has a new sexual partner and wants STI screening but has no symptoms. Which approach is most appropriate?
Discuss sexual activities, exposure sites, timing, vaccination, and risk factors with a clinician so suitable tests can be selected.
Request only a blood test because it detects every STI at every body site.
Wait until symptoms appear because screening without symptoms is inaccurate.
Use an at-home symptom checklist instead of laboratory or clinical testing.
6. Why do many healthcare sources use the term “sexually transmitted infection” (STI) rather than only “sexually transmitted disease” (STD)?
STI describes infections acquired only through intercourse.
The term STI refers only to infections that cannot be treated.
STD refers to bacterial infections, while STI refers to viral infections.
An infection can be present and transmissible without causing symptoms or recognized disease.
7. Which statement correctly compares treatment for bacterial and viral STIs?
All bacterial and viral STIs clear without medical treatment.
Antibiotics cure viral STIs but only control bacterial STIs.
No STI can be treated or medically managed once acquired.
Antibiotics can cure certain bacterial STIs but do not cure viral STIs.
8. After a possible recent exposure to HIV, what is the appropriate action regarding post-exposure prophylaxis (PEP)?
Contact a healthcare service urgently, because PEP must start as soon as possible and no later than 72 hours after exposure.
Begin PEP independently using leftover antibiotics.
Schedule a routine appointment several weeks later because timing does not matter.
Wait for symptoms before asking about PEP.
9. After possible sexual exposure, someone develops severe lower abdominal or pelvic pain with fever and feels very unwell. What is the most appropriate response?
Wait several weeks to see whether the symptoms disappear.
Seek prompt medical assessment, because severe pain and fever can require urgent evaluation.
Use a partner’s leftover antibiotics and seek care only if they fail.
Rely on an online quiz to identify the infection before seeking care.
10. Which statement about symptoms and STI transmission is accurate?
Transmission occurs only while visible symptoms are present.
The absence of symptoms reliably rules out infection after two weeks.
A person without symptoms can still have and transmit an STI.
Only viral STIs can be present without symptoms.
11. A couple uses an external condom correctly for vaginal sex. What is the most accurate conclusion?
It removes the need for STI testing in all circumstances.
It lowers the risk of many STIs, but infections spread through uncovered skin can still be transmitted.
It prevents every STI because all transmission involves semen.
It protects against pregnancy but has no effect on STI transmission.
12. A person completes treatment for a curable STI but has sex with an untreated partner soon afterward. What is an important concern?
Treatment creates permanent immunity, so there is no concern.
The person may acquire the infection again, so partner evaluation and treatment can be important.
Medication stops working whenever a partner has symptoms.
Reinfection is possible only with viral STIs.
13. Someone had an untreated syphilis infection, and the initial sore and later rash disappeared. What does that most likely mean?
The infection was cured by the immune system and cannot return.
The person is no longer infected because symptoms determine test results.
The infection may have entered a stage without symptoms and still requires medical evaluation and treatment.
The infection has changed into a harmless skin condition.
14. Which sexually transmitted infection has a vaccine that is commonly included in immunization programs and helps prevent liver disease?
Genital herpes
Chlamydia
Hepatitis B
HIV
15. Which statement about oral sex and STI transmission is correct?
Oral sex cannot transmit an STI unless ejaculation occurs.
Only HIV can be transmitted through oral sex.
Several STIs can spread through oral sex, and infection may occur in the throat or genital area.
Brushing the teeth immediately afterward prevents transmission.
16. What is the main purpose of HPV vaccination?
To prevent infection from HPV types responsible for many cancers and genital warts.
To treat an existing HPV infection immediately after symptoms appear.
To prevent all sexually transmitted infections with one vaccine.
To replace cervical screening and other recommended preventive care.
