IUPUI Biophysical Processes Exam 3
Questions With 100% Verified Answers
Urinary Tract Infection Possible Causes -
correct answer ✅Poor hygiene practices
Catheterization
Intrinsic obstructions - stone, tumor
Urinary impairment - neurogenic bladder
Renal impairment
Menopause in women can be a factor d/t vaginal pH
Acute Appendicitis -
correct answer ✅Inflammation of vermiform appendix
Most common cause of emergent abdominal surgery in children
Avg. age in US of child w/ appendicitis is 10
HIV Life Cycle -
correct answer ✅RNA virus (retrovirus) discovered in 1983
Binds to specific CD4 and chemokine receptors to enter cell
Reverse transcriptase assist to make viral DNA
Viral DNA enters cell nucleus and splices itself into genome
permanently
Viral DNA will direct cell to make HIV
,IUPUI Biophysical Processes Exam 3
Questions With 100% Verified Answers
Replication occurs fast, so often mutations making treatment even
more difficult
HIV Pathophysiology -
correct answer ✅Immune dysfunction mostly from destruction
of CD+ 4 T cells
Normal T cell life span is 100 days, whereas infected cells live only 2
days
Viral activity destroys 1 billion T cells daily
Immune problems start when CD4+ T cell counts drop below 500
cells/microliter
Normal CD4 range is 800-1200 cells/microliter
Modes of Transmission for HIV -
correct answer ✅Sex with infected partner
Exposure to infected blood or blood products
Pregnancy, delivery, or breast feeding
VERY FRAGILE outside the body
Transmission Myths for AIDS -
correct answer ✅Toilet seat
,IUPUI Biophysical Processes Exam 3
Questions With 100% Verified Answers
Swimming
Handshake
Hugging
Kissing
Dirty dishes
Sharing food
Who is at Risk for HIV -
correct answer ✅Received blood transfusion or clotting factors
before 1985
Shared needles, syringes, or other injection equipment
Sexually active, inconsistent/no protection
Babies of mothers who have HIV/AIDS
HIV and IV Drug Use -
correct answer ✅Each infected injecting drug user transmits HIV to
10 other people
1/23 women and 1/36 men IV drug users will be diagnosed with
HIV
Injecting drug users have shorter life expectancy than those who
contract the virus other ways
, IUPUI Biophysical Processes Exam 3
Questions With 100% Verified Answers
Highest Transmission of HIV -
correct answer ✅Male-to-female intercourse
Hollow bore needle for vascular access OR used IM injection
1st two-six months of infection OR 1 year after infection
Risk of transmission via unprotected receptive anal intercourse is
30 times greater than for unprotected receptive vaginal intercourse
Viral Load in the Blood -
correct answer ✅Initial infection - viremia (large viral levels in
blood) for 2-3 weeks
Transmission is more likely when viral load is high
Acute Infection of HIV -
correct answer ✅Weeks 1-3
HIV antibody test positive at 3 weeks to 3 months
FLULIKE symptoms - fever, swollen lymph glands, sore throat,
headache, malaise, muscle joint pain, D, or diffuse rash
Asymptomatic Chronic Infection -
correct answer ✅Generally asymptomatic
