Question 1

In a healthy immune system,antibodies function to

Accepted Answer

Antibodies bind to antigens and inactivate them, as well as mark them for destruction by other immune cells such as phagocytes and complement proteins. Antibodies do not create macrophages (choice A), engulf foreign particles (choice C), or signal the spleen to produce more leukocytes (choice D).

Question 2

What is a common type of cancer NOT associated with AIDS?

Accepted Answer

Lung cancer is not typically associated with AIDS. While individuals with AIDS may have an increased risk of developing lung cancer due to their weakened immune system, lung cancer is not one of the cancers specifically associated with AIDS. Kaposi's sarcoma, cancer of the lymphatic system, and invasive cervical cancer are all more commonly associated with AIDS.

Question 3

What becomes "deficient" when someone is infected with HIV?

Accepted Answer

HIV stands for Human Immunodeficiency Virus. It attacks and destroys the cells of the immune system, including white blood cells, which are responsible for fighting infections and diseases. As a result, the immune system becomes deficient and unable to protect the body from illnesses, making a person more susceptible to infections and diseases.

Question 4

AIDS is called a syndrome because

Accepted Answer

AIDS is called a syndrome because it is a collection of symptoms and infections that occur together and define the disease. It is not a single infection or disease itself.

Question 5

AIDS

Accepted Answer

AIDS is an acronym for acquired immunodeficiency syndrome.

Question 6

A Lymphocytes include

Accepted Answer

Lymphocytes include B cells and several types of T cells. Antigens and antibodies are related to immune response but not specific to lymphocytes. Macrophages are a type of white blood cell, but not a subtype of lymphocytes.

Question 7

Two years after becoming HIV positive,Gordon suddenly loses a great deal of weight,feels very weak,and has persistent diarrhea.This condition is called

Accepted Answer

Wasting syndrome is a condition that can occur in people with advanced HIV infection. Symptoms include significant weight loss, weakness, and diarrhea that lasts for more than a month. This is caused by the virus attacking the gastrointestinal tract and interfering with nutrient absorption. CMV, leukemia, and lymphoma are all possible complications of HIV infection but do not typically cause the specific symptoms described.

Question 8

Kaposi's sarcoma refers to a cancer of the

Accepted Answer

Kaposi's sarcoma specifically refers to cancer that originates in the cells lining blood vessels, leading to abnormal growths or lesions. It often manifests as purple or red patches on the skin or inside the mouth, but it can also affect other organs such as the lungs or digestive tract if it spreads beyond the blood vessels.

Question 9

Which of the following diseases were observed in healthy young men,essentially triggering research which resulted in identifying HIV/AIDS?

Accepted Answer

Kaposi's sarcoma was observed in healthy young men in the 1980s, which led to the discovery of HIV/AIDS.

Question 10

According to the text,the most profound changes in human sexuality over the past 30 years have occurred as a result of

Accepted Answer

The text indicates that the most profound changes in human sexuality over the past 30 years have been due to HIV, which has significantly impacted sexual behavior and awareness.

Question 11

Charles has been experiencing changes in his moods and,consequently,in his behavior.He has been having difficulty moving around and frequently forgets what he is about to do.What clinical condition associated with AIDS is he suffering from?

Accepted Answer

Charles is exhibiting symptoms of cognitive impairment, which is associated with AIDS dementia. The other options do not specifically describe the symptoms Charles is experiencing.

Question 12

How did scientific awareness of HIV begin?

Accepted Answer

In the early 1980s, doctors began to notice an increase in rare diseases such as Kaposi's sarcoma and pneumocystis pneumonia in healthy young men in major U.S. cities. This led to the eventual identification of HIV as the virus responsible for AIDS.

Question 13

Several months after being told he has tested positive for HIV,Maury begins to develop fluid in his lungs.A treating physician tells Maury that he has the most common opportunistic infection,namely

Accepted Answer

The development of fluid in the lungs several months after testing positive for HIV suggests that Maury's immune system may be compromised. Pneumocystis carinii pneumonia is a common opportunistic infection that affects individuals with weakened immune systems, particularly those with HIV/AIDS. Bacterial pneumonia can occur in anyone, regardless of immune status. Mycobacterium avium intracellulare (MAI) is a bacterial infection that can affect individuals with advanced HIV/AIDS, but it typically affects other areas of the body rather than the lungs. Toxoplasmosis is a parasitic infection that can also affect individuals with HIV/AIDS, but it does not typically lead to fluid in the lungs. Therefore, the best choice is B - pneumocystis carinii pneumonia.

Question 14

Miranda just received the results of her HIV/AIDS screening blood tests and it showed HIV antibodies and a T-cell count below 200.What does this mean?

Accepted Answer

The answer of Miranda just received the results of her...

Question 15

Your friend Dean has been battling HIV for several years.Recently you have noticed purplish blotches appearing on his skin.Most likely,he is dealing with

Accepted Answer

Kaposi's sarcoma is a common opportunistic infection in people with HIV/AIDS and is characterized by purplish blotches on the skin. Mycobacterium avium intracellulare and PCP are also opportunistic infections in people with HIV/AIDS, but they do not typically present with purplish skin lesions. Skin lymphoma is a type of cancer that affects the skin, but it is not commonly associated with HIV/AIDS.

Question 16

Which of the following statements about the leukocyte is FALSE?

Accepted Answer

Platelets are not leukocytes. Platelets are small cell fragments that are important in blood clotting.

Question 17

______________ engulf foreign particles.

Accepted Answer

Macrophages are a type of white blood cell that play a role in the immune system by engulfing and digesting foreign particles, such as bacteria and viruses. Red blood cells are involved in oxygen transport, plasma is the liquid portion of blood that carries nutrients and waste products, and hormones are chemical messengers.

Question 18

To say that AIDS is an acquired disease means that it is

Accepted Answer

AIDS is not inherited, it is acquired through certain behaviors or exposure to the virus. It is not passed down from parents to offspring like some genetic diseases. AIDS is primarily transmitted through unprotected sexual contact, sharing of needles or other injection equipment, or mother-to-child transmission during pregnancy, birth, or breastfeeding. While AIDS is easily transmitted in certain situations, it is not classified as an easily transmitted disease like the flu or common cold.

Question 19

AIDS stands for

Accepted Answer

AIDS stands for Acquired Immune Deficiency Syndrome, which refers to a condition where the immune system is weakened, making individuals more susceptible to infections and diseases.

Question 20

All of the following groups were affected early by the spread of HIV EXCEPT

Accepted Answer

Latinos were not among the earliest groups identified as being affected by the spread of HIV. Initially, the epidemic was most prominently recognized among gay men, hemophiliacs, and Haitians.
