Question 1

Babies are at risk of getting a herpes infection from their mothers during childbirth, sometimes with fatal consequences. Given that a person exposed to herpes will develop antibodies to the disease, a mother who is most likely to pass the virus to her child is one

Accepted Answer

A mother who had herpes very late in pregnancy is most likely to pass the virus to her child because she may not have developed antibodies yet, increasing the risk of transmission during childbirth.

Question 2

A woman develops a series of small bumps or warts around the opening to her vagina. They are painless, but soon afterward, her boyfriend develops similar warts on his penis. It is likely that this couple is infected by

Accepted Answer

HPV types 6 and 11 are commonly associated with genital warts, which are typically painless and can be transmitted between sexual partners.

Question 3

A doctor would most likely use a Pap test to determine if a person has

Accepted Answer

A Pap test is primarily used to screen for cervical cancer by detecting precancerous or cancerous cells on the cervix.

Question 4

HPV vaccination may have a more dramatic effect on people's health in the developing world than in the United States because

Accepted Answer

In developing countries, access to regular Pap tests, which can detect cervical cancer early, is limited. Therefore, HPV vaccination can significantly reduce the incidence of cervical cancer in these regions.

Question 5

There are approximately 100 kinds of human papillomaviruses (HPV). Two of these, HPV 16 and 18, are responsible for

Accepted Answer

HPV 16 and 18 are known to be high-risk types that are responsible for the majority of cervical cancer cases.

Question 6

A young gay man is diagnosed with the hepatitis A virus. He most likely picked up the virus through

Accepted Answer

The answer of A young gay man is diagnosed with...

Question 7

Dave has recently been diagnosed with hepatitis B. Given current knowledge and statistics related to this disease, Dave's most likely prognosis is that he will

Accepted Answer

Most adults with hepatitis B recover completely and become noninfectious, as the immune system clears the virus. Chronic infection is more common in infants and children.

Question 8

Which statement comparing hepatitis A and hepatitis B is correct?

Accepted Answer

Hepatitis A is an acute infection and does not become chronic, while hepatitis B can lead to chronic infection.

Question 9

A couple is engaging in unprotected sex. The risk of a member of the couple contracting an HIV infection is greatest for

Accepted Answer

The risk of contracting HIV is highest for the receptive partner during anal sex due to the delicate tissue and higher likelihood of tears, which can facilitate the transmission of the virus.

Question 10

A major result of the process of seroconversion during infection with HIV is that a person

Accepted Answer

During seroconversion, the body produces antibodies to HIV, which can lead to a temporary decrease in blood levels of the virus, but the disease is not eliminated.

Question 11

Given that the body is able to produce antibodies against HIV, why do many people still progress from HIV infection to full-blown AIDS?

Accepted Answer

HIV specifically targets and destroys CD4+ T cells, which are crucial for the immune response, including the production and function of antibodies. This compromises the immune system's ability to fight the virus effectively, leading to the progression to AIDS.

Question 12

Refer to the figure.
 The figure illustrates the sites of actions of various antiretroviral drugs used to treat HIV and AIDS. The fusion inhibitor, or entry inhibitor, acts at which point in the HIV replication cycle?

Accepted Answer

The answer of Refer to the figure.
 The figure illustrates...

Question 13

The worldwide AIDS pandemic shows some signs of abating, according to statistics collected between 2000 and 2016. This decline is most likely due to

Accepted Answer

The decline in the AIDS pandemic is primarily attributed to the development and widespread use of new, highly effective antiviral drugs, which have significantly improved the management and treatment of HIV/AIDS.

Question 14

John is a sexually active gay man who has tested HIV-negative. What type of HIV treatment would his doctor most likely recommend for John?

Accepted Answer

Pre-exposure prophylaxis (PrEP) is recommended for individuals who are at high risk of HIV exposure, such as sexually active gay men, to prevent infection before potential exposure.

Question 15

AIDS was first recognized as a new disease when it

Accepted Answer

AIDS was first recognized as a new disease in the late 1970s and early 1980s when it caused outbreaks among gay men in U.S. cities, leading to its identification and the beginning of research into its causes and transmission.

Question 16

Which behavior is most likely to prevent a person from contracting an STI?

Accepted Answer

The answer of Which behavior is most likely to prevent...

Question 17

Which sexual behaviors carry the highest risk for STI transmission?

Accepted Answer

Anal sex and coitus carry the highest risk for STI transmission due to the potential for exchange of bodily fluids and the delicate nature of the tissues involved, which can lead to micro-tears and increased susceptibility to infections.

Question 18

Which condition is not an STI but is sometimes mistaken for herpes?

Accepted Answer

The answer of Which condition is not an STI but...

Question 19

Discuss the history of STIs, including transmission, prevalence, early views of STIs, the beliefs about the morality of those infected, and the resulting individual, social, and political responses to STIs.

Accepted Answer

The answer of Discuss the history of STIs, including transmission,...

Question 20

Provide evidence to support the claim that STIs are still a major problem in the United States.

Accepted Answer

The answer of Provide evidence to support the claim that...
