ATI Immune System Disorders Exam Newest 2026
Questions and Correct Detailed Answers Already
Graded A+
HIV is a - CORRECT ANSWER-retrovirus that is transmitted through blood and
body fluids
HIV target - CORRECT ANSWER-CD4 lymphocytes (AKA T-cells)
HIV integrates *RNA* into host cell DNA through - CORRECT ANSWER-
*reverse transcriptase*, reshaping the host's immune system
progression of HIV infection - CORRECT ANSWER-- manifestations occur within
2 to 4 weeks of infection
- symptoms are similar to those of influenza and can include a rash and a sore
throat
- this stage is marked by a rapid rise in HIV viral load, decreased CD4+ cells, and
increased CD8
- the resolution of clinical manifestations coincide with the decline in viral HIV
copies
- lymphadenopathy persists throughout the disease process
,chronic asymptomatic infection - CORRECT ANSWER-- this stage may be
prolonged and clinically silent (asymptomatic)
- the client may remain asymptomatic for 10 years or more
- anti-HIV antibodies are produced (HIV positive)
- overtime, the virus begins active replication using the host's genetic machinery:
CD4+ cells are destroyed, the viral load increases, dramatic loss of immunity
begins
AIDS - CORRECT ANSWER-- this stage is characterized by life-threatening
opportunistic infections
- this is the end stage of HIV infection. Without tx, death occurs within 5 years
- all people with AIDS have HIV, but not all people with HIV have AIDS
HIV medication - CORRECT ANSWER-Highly active antiretroviral therapy
(HAART) involves using three to four HIV medications in combination with other
antiretroviral medications to reduce medication resistance, adverse effects, and
dosages.
Infusion inhibitors - enfuvirtide (Fuzeon) - CORRECT ANSWER-Blocks the fusion
of HIV with the host cell
, neutrophils increased in relation to - CORRECT ANSWER-acute bacterial
infection, fungal infection
neutrophils decreased in relation to - CORRECT ANSWER-sepsis, radiation
therapy, aplastic anemia, chemotherapy, and influenza
lymphocytes (T cells and B cells) increased in relation to - CORRECT ANSWER--
chronic bacterial or viral infection
- viruses such as mononucleosis, mumps, and measles
- bacteria such as hepatitis
- lymphocytic leukemia, multiple myeloma
lymphocytes (T cells and B cells) decreased in relation to - CORRECT ANSWER-
leukemia, sepsis
T-lymphocytes initiate - CORRECT ANSWER-cell-mediated immunity
B-lymphocytes initiate - CORRECT ANSWER-humoral immunity
