Unit 7 - Class Acitivities Flashcards
Which substance most easily transmits the human immunodeficiency virus (HIV)?
A.Blood
B.Feces
C.Saliva
D.Urine
A.Blood
The following lesions found on an AIDS patient would be linked to what condition:
A.Kaposi’s Sarcoma
B.Herpes Simplex
C.Varicella
D.ITP
A.Kaposi’s Sarcoma
*an “AIDS defining” illness. This means that when KS occurs in someone infected with HIV, that person officially has AIDS (and is not just HIV-positive).
What is a specific term for a bacterial or other foreign protein that initiates antibody production by the body?
A. peptide
B. MHCII molecule
C. complement
D. antigen
D. antigen
*When macrophages eat bacteria, proteins (antigens) from the bacteria are broken down into short peptide chains and then “displayed” on the macrophage surface attached to MHCII molecules.
Which immune cell is responsible for the quickest release of histamine that causes the red itchy welts associated with allergies?
A. mast cell
B. lymphocyte
C. eosinophil
D. basophil
A. mast cell
*In our skin just outside of the capillaries lurk the mast cells ready and waiting with allergen receptors
What is the term used to describe white blood cells migrating toward bacteria?
A. zeiosis
B. phagocytosis
C. chemotaxis
D. phototaxis
C. chemotaxis
*Chemotaxis is the movement of a cell or organism in response to a chemical stimulus.
Name the process a cell such as a neutrophil or a macrophage uses to ingest (eat) its prey.
A. halitosis
B. chemotaxis
C. botulism
D. phagocytosis
D. phagocytosis
*The term phagocytosis comes from the ancient Greek words phagein (“to devour”) and kytos (“cell”). “Osis” means process. So this is the cellular process of eating
Which of these cell types can play a primary role in attacking and killing cancer cells?
A. red blood cell
B. cytotoxic T cell
C. platelet
D. mast cell
B. cytotoxic T cell
*Cytotoxic T lymphocytes (CTLs) recognize surface markers on target cells in the body. Target cells may be cancer cells or infected cells.
Diseases in which a person immune system attacks the person own normal tissue are called
A.Secondary immune diseases B.Autoimmune diseases C.Antigen shifting diseases D.Primary immune diseases E.Clonal selection diseases
B.Autoimmune diseases
Which of the following are autoimmune diseases?
A.Heart disease B.Hashimoto’s thyroiditis C.Erythroblastosis fetalis D.Systemic lupus erythematosus E.B & D
E.B & D
Which from of unprotected sex is more likely to put you at risk for HIV infection?
A.Oral sex
B.Anal sex
C.Vaginal sex
D.Masturbation
B.Anal sex
- The walls of the anus and rectum are thin and have many blood vessels that can be injured during anal sex. HIV-infected semen can be easily absorbed through these thin walls and into the bloodstream. Injured tissue in the anus and rectum can expose the penis to blood containing HIV.
- Using latex condoms for anal sex lowers HIV risk, but condoms fail more often during anal sex than during vaginal or oral sex. So, protected anal sex is still riskier than protected vaginal or oral sex ( always use water based lubricant)
- How is HIV spread during oral sex? Although oral sex is less risky than anal or vaginal sex, it is possible to get HIV by performing oral sex on an HIV-infected partner. HIV transmission could potentially occur if blood, pre-ejaculation fluid, semen, or vaginal fluids enter open sores or cuts in or around the mouth, such as those caused by canker sores or blisters, vigorous teeth brushing or flossing, or some form of trauma. Using a latex barrier, like a condom or dental dam, reduces your risk of HIV infection
Can I get HIV from body piercing, ear piercing, or tattoo needles?
A.Yes
B.No
A. Yes
Male Circumcision can reduce heterosexually HIV infection in males by approximately 60%
A.True
B.False
A.True
*Medical male circumcision, when safely provided by well-trained health professionals, reduces the risk of heterosexually acquired HIV infection in men by approximately 60%.This is a key intervention in generalized epidemic settings with high HIV prevalence and low male circumcision rates.
A nurse caring for a client with acquired immunodeficiency syndrome is working with a nursing student. She notes the student doesn’t attempt to suction or assist with care of the client. Which action is appropriate?
A.Talk to the student
B.Talk to the charge nurse
C.Address a coworker with the concerns
D.Seek advice from the students instructor
A.Talk to the student
*The nurse should approach the student to determine her feeling and experience in caring for this client. The charge nurse and coworkers aren’t familiar with the student’s abilities but the instructor may be approached if the nurse can’t communicate with the student
A declining AIDS patients significant other is tearful over the client’s condition and lack of improvement, He says he feels powerless and unable to help his friend. Which response by the nurse is the best?
A.Agree with the person
B.Tell him there’s nothing he can do
C.State she understands how he must feel
D.Ask if he would like to help with some comfort measures
D.Ask if he would like to help with some comfort measures
*The significant other expresses a need to help and the nurse can encourage him to do whatever he feels comfortable with, such as putting lubricant on lips, moist cloth on the forehead, or lotion on skin. The nurse may not understand his situation and agreeing with a person doesn’t diminish powerlessness. There are many ways the significant other can help if he wants to.
Which of the following statements about HIV is true?
A.The disease is highly infectious
B.The fatality rate is low if the disease is detected in its early stages
C.Most people who get AIDS die of pneumonia
D.All of the above
E.None of the above
B.The fatality rate is low if the disease is detected in its early stages
