A treatment option for severe combined immune deficiency (SCID) includes

a stem cell transplant

What is the term that refers to vascular lesions caused by dilated blood vessels?

Telangiectasia

Which assessment finding would the nurse expect to document for a client with ataxia-telangiectasis?

Vascular lesions Ataxia-telangiectasis is characterized by loss of muscle coordination and vascular lesions

A nurse is assessing a client with Kaposi's sarcoma. What initial sign does the nurse know to look for during assessment?

Deep purple cutaneous lesions Localized cutaneous lesions may be the first manifestation of this HIV-related malignancy, which appears in 90% of clients as immune function deteriorates. Other symptoms develop over time as the lesions increase in size and spread to other locations

A client with severe combined immunodeficiency is to receive a hematopoietic stem cell transplant. What would the nurse expect to be started?

Immunosuppressive agents For a client undergoing a hematopoietic stem cell transplant, immunosuppression is started to ensure engraftment of depleted bone marrow. Antibiotic therapy may or may not be indicated. Chest physiotherapy would be appropriate for clients with ataxia-telangiectasis who have chronic lung disease

A client that is HIV+ has been diagnosed with Pneumocystis pneumonia caused by P. jiroveci. What medication does the nurse expect that the client will take for the treatment of this infection?

Trimethoprim-sulfamethoxazole To prevent and treat Pneumocystis pneumonia, trimethoprim-sulfamethoxazole (Bactrim, Septra) is prescribed. The other medications are antifungals and used to treat candidiasis

HIV is harbored within which type of cell?

Lymphocyte Because HIV is harbored within lymphocytes, a type of white blood cell, any exposure to infected blood results in significant risk of infection. HIV infection is not harbored in platelets, erythrocytes, or nerve cells

A client taking fosamprenavir reports "getting fat." What is the nurse's best action?

Teach the client about medication side effects The client needs to be aware of the potential for fat redistribution

A nurse is collecting objective data for a client with AIDS. The nurse observes white plaques in the client's oral cavity, on the tongue, and buccal mucosa. What does this finding indicate?

Candidiasis is a yeast infection caused by the Candida albicans microorganisms. It may develop in the oral, pharyngeal, esophageal, or vaginal cavities or in folds of the skin. It is often called thrush when located in the mouth. Inspection of the mouth, throat, or vagina reveals areas of white plaque that may bleed when mobilized with a cotton-tipped swab

A client who has AIDS is being treated in the hospital and admits to having periods of extreme anxiety. What would be the most appropriate nursing intervention?

Teach the client guided imagery Measures such as relaxation and guided imagery may be beneficial because they decrease anxiety, which contributes to weakness and fatigue.

The nurse is admitting a client to the unit with a diagnosis of ataxia-telangiectasia. The nurse would recognize that the client is exhibiting telangiectasia when assessing the presence of what?

Vascular lesions caused by dilated blood vessels

A client is suspected of having an immune system disorder. The health care provider wants to perform a diagnostic test to confirm the diagnosis. What test should the nurse prepare the client for?

Enzyme-linked immunosorbent assay T-cell and B-cell assays (or counts) and the enzyme-linked immunosorbent assay may be performed

When learning about HIV/AIDS, the student should be able to differentiate the two subtypes of virus by which characteristic?

HIV-1 is more prevalent than HIV-2 subtypes Two HIV subtypes have been identified: HIV-1 and HIV-2. HIV-1 mutates easily and frequently, producing multiple substrains that are identified by letters from A through O. HIV-2 is less transmittable, and the interval between initial infection with HIV-2 and development of AIDS is longer. HIV-1 is more prevalent in the United States and in the rest of the world. Western Africa is the primary site of infection with HIV-2

A client is beginning highly active antiretroviral therapy (HAART). The client demonstrates an understanding of the need for follow up when scheduling a return visit for viral load testing at which time?

6 weeks Viral load tests are measured immediately before initiating antiretroviral therapy and then again in 2 to 8 weeks. In most clients, adherence to a regimen of potent antiretroviral agents should result in a large decrease in the viral load by 2 to 8 weeks. Therefore, a return visit at 6 weeks would be in this time frame.

What does the nurse understand will result if the patient has a deficiency in the normal level of complement?

Increased susceptibility to infection The complement system is an integral part of the immune system, and deficiencies in normal levels of complement result in increased susceptibility to infectious diseases and immune-mediated disorders

A client is diagnosed with severe combined immunodeficiency (SCID). What would the nurse expect to integrate into the client's plan of care?

Preparation for bone marrow transplantation

The nurse is aware that the most prevalent cause of immunodeficiency worldwide is

The most prevalent cause of immunodeficiency worldwide is severe malnutrition

The period from infection with HIV to the development of HIV-specific antibodies is known as

primary infection, acute, or stage 1

The nurse is preparing to administer the recommended dose of intravenous gamma-globulin for a 60-kg male client. How many grams will the nurse administer?

30 g The optimal dose is determined by the client's response. In most instances, an IV dose of 200-800 mg/kg of body weight is administered every 3-4 weeks to ensure adequate serum levels of immunoglobulin G (IgG).

A client with AIDS has become forgetful with a limited attention span, decreased ability to concentrate, and delusional thinking. What condition is represented by these symptoms?

AIDS dementia complex (ADC) ADC, a neurologic condition, causes the degeneration of the brain, especially in areas that affect mood, cognition, and motor functions. Such clients exhibit forgetfulness, limited attention span, decreased ability to concentrate, and delusional thinking.

A nurse educator is preparing to discuss immunodeficiency disorders with a group of fellow nurses. What would the nurse identify as the most common secondary immunodeficiency disorder?

AIDS, the most common secondary disorder, is perhaps the best-known secondary immunodeficiency disorder. It results from infection with the human immunodeficiency virus (HIV).

A hospital client is immunocompromised because of stage 3 HIV infection and the physician has ordered a chest radiograph. How should the nurse most safely facilitate the test?

Arrange for a portable x-ray machine to be used A client who is immunocompromised is at an increased risk of contracting nosocomial infections due to suppressed immunity. The safest way the test can be facilitated is to have a portable x-ray machine in the client's room

A client is prescribed didanosine as part of a highly active antiretroviral therapy (HAART). Which instruction would the nurse emphasize with this client?

Be sure to take this drug about 1/2 hour before or 2 hours after you eat Didanosine (Videx) should be taken 30 to 60 minutes before or 2 hours after meals. Other antiretroviral agents, such as abacavir, emtricitabine, or lamivudine can be taken without regard to meals. High-fat meals should be avoided when taking amprenavir. Atazanavir should be taken with food and not with antacids

The nurse practitioner who is monitoring the patient's progression of HIV is aware that the most debilitating gastrointestinal condition found in up to 90% of all AIDS patients is

Chronic diarrhea is believed related to the direct effect of HIV on cells lining the intestine. Although all gastrointestinal manifestations of AIDS can be debilitating, the most devastating is chronic diarrhea. It can cause profound weight loss and severe fluid and electrolyte imbalances

More than 50% of individuals with this disease develop pernicious anemia

Common variable immunodeficiency (CVID) More than 50% of clients with CVID develop pernicious anemia. Pernicious anemia is not associated with the other conditions

Which blood test confirms the presence of antibodies to HIV?

Enzyme immunoassay (EIA) EIA and Western blotting identify and confirm the presence of antibodies to HIV. ESR is an indicator of the presence of inflammation in the body. p24 antigen test is a blood test that measures viral core protein.

A client suspected of having human immunodeficiency virus (HIV) has blood drawn for a screening test. What is the first test generally run to see if a client is, indeed, HIV positive?

Enzyme-linked immunosorbent assay (ELISA) The ELISA test, an initial HIV screening test, is positive when there are sufficient HIV antibodies; it also is positive when there are antibodies from other infectious diseases. If the ELISA is positive twice then the Western Blot test is run

What intervention is a priority when treating a client with HIV/AIDS?

Fluid and electrolyte deficits are a priority in monitoring clients with HIV/AIDS, and assessment of fluid loss and electrolyte imbalance is essential

A healthcare worker has been exposed to the blood of an HIV-positive client and is awaiting the results of an HIV test. In the meantime, what precautions must the healthcare worker take to prevent the spread of infection?

Follow the same sexual precautions as someone who has been diagnosed with AIDS The healthcare worker will be tested for HIV at regular intervals and treated with antiretrovirals depending on the results of the tests or the potential for infection. While awaiting the results, the healthcare worker should follow the same sexual precautions as someone who has been diagnosed with AIDS. The healthcare worker should not limit interactions with either non-HIV-infected or HIV-infected people.

Which condition is an early manifestation of HIV encephalopathy?

Headache Early manifestations of HIV encephalopathy include headache, memory deficits, difficulty concentrating, progressive confusion, psychomotor slowing, apathy, and ataxia. Later stages include hyperreflexia, a vacant stare, and hallucinations

Which substance may be used to lubricate a condom?

K-Y jelly is water-based and will provide lubrication while not damaging the condom. The oils in skin lotion and petroleum jelly, and baby oil, will cause a latex condom to break

Kaposi sarcoma (KS) is diagnosed through

KS is diagnosed by biopsy of the suspected lesions. Prognosis depends on the extent of the tumor, the presence of other symptoms of HIV infection, and the CD4+ count

Which option should the nurse encourage to replace fluid and electrolyte losses in a client with AIDS?

Liquids The nurse should encourage clients with AIDS to consume liquids in order to help replace fluid and electrolyte losses. Gluten and sucrose may increase the complication of malabsorption. Large doses of iron and zinc should be avoided because they can impair immune function

A client is receiving ganciclovir as part of the treatment for cytomegalovirus retinitis. What would the nurse monitor the results of the client's laboratory tests for?

Neutropenia A common reaction to ganciclovir is severe neutropenia. Hypocalcemia and hyperphosphatemia are associated with foscarnet. Ganciclovir is not associated with thrombocytopenia

A female client comes to the clinic and tells the nurse, "I think I have another vaginal infection and I also have some wart-like lesions on my vagina. This is happening quite often." Which nursing action is the priority for this client?

Offer information on human immunodeficiency virus (HIV) testing In women, gynecologic problems may be the focus of the chief complaint for clients who are HIV positive but not yet diagnosed. Abnormal results of Papanicolaou tests, genital warts, pelvic inflammatory disease, and persistent vaginitis may also correlate with HIV infection. Based on this information, the priority nursing action is to offer information on HIV testing to the client

The nurse completes a history and physical assessment on a client with acquired immune deficiency syndrome (AIDS) who was admitted to the hospital with respiratory complications. The nurse knows to assess for what common infection (80% occurrence) in persons with AIDS?

Pneumocystis pneumonia .Pneumocystic pneumonia (PCP) is one of the first and most common opportunistic infections associated with AIDS. It may be present despite the absence of crackles. If untreated, PCP progresses to cause significant pulmonary impairment and respiratory failure

A patient had unprotected sex with an HIV-infected person and arrives in the clinic requesting HIV testing. Results determine a negative HIV antibody test and an increased viral load. What stage does the nurse determine the patient is in?

Primary infection

The nurse's plan of care for a client with stage 3 HIV addresses the diagnosis of Risk for Impaired Skin Integrity Related to candidiasis. What nursing intervention best addresses this risk?

Providing thorough oral care before and after meals Thorough mouth care has the potential to prevent or limit the severity of this infection. Antibiotics are irrelevant because of the fungal etiology. The patient requires adequate food and fluids, but these do not necessarily prevent candidiasis. Skin emollients are not appropriate because candidiasis is usually oral

The nurse is caring for a patient with an immunodeficiency disorder. What cardinal symptoms of immunodeficiency does the nurse recognize while caring for this patient?

Regardless of the underlying cause, the cardinal symptoms of immunodeficiency include chronic or recurrent and severe infections, infections caused by unusual organisms or by organisms that are normal body flora, poor response to standard treatment for infections, and chronic diarrhea

Nursing students are reviewing the pathophysiology of human immunodeficiency virus (HIV). They demonstrate understanding of the information when they state which of the following as the form of the genetic viral material?

Ribonucleic acid (RNA) HIV is a retrovirus that carries its genetic material in the form of RNA rather than DNA. HIV consists of a viral core containing the viral RNA, surrounded by an envelope consisting of protruding glycoproteins

A client in a late stage of acquired immunodeficiency syndrome (AIDS) shows signs of AIDS-related dementia. Which nursing diagnosis takes highest priority?

Risk for injury In a client with AIDS, central nervous system (CNS) deterioration can lead to AIDS-related dementia. This type of dementia impairs cognition and judgment, placing the client at risk for injury

A client with AIDS is admitted to the hospital with severe diarrhea and dehydration. The physician suspects an infection with Cryptosporidium. What type of specimen should be collected to confirm this diagnosis?

Stool specimen for ova and parasites A stool specimen for ova and parasites will give a definitive diagnosis. The organism is spread by the fecal-oral route from contaminated water, food, or human or animal waste. Those infected can lose from 10 to 20 L of fluid per day. Losing this magnitude of fluid quickly leads to dehydration and electrolyte imbalances

The term used to define the amount of virus in the body after the initial immune response subsides is

The amount of virus in the body after the initial immune response subsides is referred to as the viral set point, which results in an equilibrium between HIV levels and the immune response that may be elicited. During the primary infection period, the window period occurs because a person is infected with HIV but negative on the HIV antibody blood test. The period from infection with HIV to the development of antibodies to HIV is known as the primary infection stage. The amount of virus in circulation and the number of infected cells equals the rate of viral clearance

The nurse is gathering data from laboratory studies for a client who has HIV. The clients T4-cell count is 200/mm3, and the client has been diagnosed with Pneumocystis pneumonia. What does this indicate to the nurse?

The client has converted from HIV infection to AIDS AIDS is the end stage of HIV infection. Certain events establish the conversion of HIV infection to AIDS: a markedly decreased T4 cell count from a normal level of 800 to 1200/mm3 and the development of certain cancers and opportunistic infections. The client does not have advanced HIV; they meet the criteria for the development of AIDS. The T4-cell count is not decreasing due to an infection

The nurse receives a phone call at the clinic from the family of a client with AIDS. They state that the client started "acting funny" and reported headache, tiredness, and a stiff neck. Checking the temperature resulted in a fever of 103.2°F. What should the nurse inform the family member?

The client may have cryptococcal meningitis and will need to be evaluated by the health care provider A fungal infection, Cryptococcus neoformans is another common opportunistic infection among clients with AIDS, and it causes neurologic disease. Cryptococcal meningitis is characterized by symptoms such as fever, headache, malaise, stiff neck, nausea, vomiting, mental status changes, and seizures

When a nurse infuses gamma globulin intravenously, the rate should not exceed?

The intravenous infusion should be administered at a slow rate, not to exceed 3 mL/min

A client is scheduled to receive an intravenous immunoglobulin (IVIG) infusion. The client asks the nurse about the infusion's administration and its adverse effects. Which condition should the nurse instruct this client to report immediately?

Tickle in the throat Continually assess the client for adverse reactions; be especially aware of complaints of a tickle or lump in the throat, which could be the precursor to laryngospasm that precedes bronchoconstriction

The balance between the amount of HIV in the body and the immune response is the

Viral set point The balance between the amount of HIV in the body and the immune response is the viral set point. A viral load test measures the quantity of HIV RNA in the blood. The window period is the time from infection with HIV until seroconversion detected on HIV antibody test. Anergy is the loss or weakening of the body's immunity to an irritating agent or antigen

A client with suspected exposure to HIV has been tested with the enzyme-linked immunosorbent assay (ELISA) with positive results twice. The next step for the nurse to explain to the client for confirmation of the diagnosis is to perform a:

Western blot test for confirmation of diagnosis The enzyme-linked immunosorbent assay (ELISA) test, an initial HIV screening test, is positive when there are sufficient HIV antibodies; it also is positive when there are antibodies from other infectious diseases. The test is repeated if results are positive. If results of a second ELISA test are positive, the Western blot is performed.

A client with AIDS has been tested for cytomegalovirus (CMV) with positive titers. What severe complication should the nurse be alert for with cytomegalovirus?

blindness CMV can infect the choroid and retinal layers of the eye, leading to blindness

The nurse assesses a client who is diagnosed with human immunodeficiency virus (HIV) for adverse reactions associated with the prescribed medication, abacavir. The nurse provides emergency intervention when the client exhibits the following symptoms:

dyspnea cough sore throat Antiretroviral therapy (ART) is supported by evidence-based practice guidelines for the treatment of HIV; however, there are certain adverse reactions associated with nucleoside reverse transcriptase inhibitors (NRTIs), a type of ART, that the nurse must monitor for in the provision of client care. A client who is prescribed abacavir is at risk for anaphylaxis; thus, respiratory symptoms, including a sore throat, a cough, and/or dyspnea, require emergency action by the nurse

A client with end-stage acquired immunodeficiency syndrome (AIDS) has profound manifestations of Cryptosporidium infection caused by the protozoa. What client need should in the nurse focus on when planning this client's care?

fluid replacement The protozoal enteric infection caused by Cryptosporidium results in profuse watery diarrhea. Because diarrhea will lead to dehydration, the nurse should focus on fluid replacement

A patient with common variable immunodeficiency (CVID) is extremely fatigued and not feeling well. What lab test does the nurse anticipate the patient will have to detect a common development related to the disease?

B12 level More than 50% of patients with CVID develop pernicious anemia, a condition in which the body cannot make enough red blood cells due to an inability to absorb vitamin B12

The nurse is reviewing the medical record of a client who is positive for human immunodeficiency virus (HIV). The nurse notes that the client is classified as HIV asymptomatic based on which CD4+ T lymphocyte count?

CD4+ T lymphocyte count Greater than 500/mm3 A client is classified as HIV asymptomatic when the CD4+ T lymphocyte count is greater than 500/mm3. A person is considered HIV symptomatic when the CD4+ count is 200 to 499/mm3. A person is considered to have acquired immunodeficiency syndrome (AIDS) when the CD4+ count is less than 200/mm3

When a nurse infuses gamma globulin intravenously, the rate should not exceed

3 mL/min The intravenous infusion should be administered at a slow rate, not to exceed 3 mL/min.

A client with ataxia-telangiectasia is admitted to the unit. The nurse caring for the client would expect to see what included in the treatment regimen?

IV gamma globulin administration Treatment for ataxia-telangiectasia includes IV gamma globulin, antimicrobial therapy, and bone marrow transplantation

What test will the nurse assess to determine the client's response to antiretroviral therapy?

Viral load should be measured at baseline and on a regular basis thereafter because viral load is the most important indicator of response to ART. The other tests are not used in this way

Which microorganism is known to cause retinitis in people with HIV/AIDS?

Cytomegalovirus Cytomegalovirus is a species-specific herpes virus. C. neoformans is a fungus that causes an opportunistic infection in clients with HIV/AIDS

A patient is on highly active antiretroviral therapy (HAART) for the treatment of HIV. What does the nurse know would be an adequate CD4 count to determine the effectiveness of treatment for a patient per year?

50 mm^3 to 150 mm^3 An adequate CD4 response for most patients on HAART is an increase in CD4 count in the range of 50 mm3 to 150 mm3 per year, generally with an accelerated response in the first 3 months

A client with acquired immune deficiency syndrome (AIDS) reports diarrhea after every meal. What is the nurse's best response?

Avoid residue, lactose, fat, and caffeine Diarrhea may subside when the client avoids residue, lactose, fat, and caffeine. Although eating may seem to cause diarrhea, the client must understand that limiting the intake of food to control diarrhea only exacerbates wasting. The client will tolerate a low-fat, high-carbohydrate, soft or liquid diet better than large, high-fat meals. The client should be advised to avoid large doses of iron and zinc because they can impair the functioning of the immune system

Which term means a lack of one or more of the five immunoglobulins?

Hypogammaglobulinemia

When describing the effects of treatment for phagocytic cell disorders, which of the following would the nurse include as being the most successful?

Hematopoietic stem cell transplantation has proven to be a successful curative modality for phagocytic disorders

The nurse is talking with a group of teens about transmission of human immunodeficiency virus (HIV). What body fluids does the nurse inform them will transmit the virus? Select all that apply. semen urine breast milk blood vaginal secretions

semen breast milk blood vaginal secretions There are only four known body fluids through which HIV is transmitted: blood, semen, vaginal secretions, and breast milk. HIV may be present in saliva, tears, and conjunctival secretions, but transmission of HIV through these fluids has not been implicated
