Secondary TNIs for Communicable Disease
Early diagnosis and treatment
Example:
Screening - recognize disease and prevent spread
Tertiary Prevention
Restoration to optimum function
Examples:
- Isolation: to limit new individuals coming into contact with the infection
- Transmission based precautions
- Immune system enhancement
- Provide comfort
HIV Infection Transmission
Transmissible Body Fluid + Point of entry into blood stream = exposure
What are the modes of transmission for HIV?
- Sexual
- Blood and blood products
- Perinatal transmission
What is pretest counseling?
Pretest counseling is an appointment made prior to be tested for HIV. It establishes rapport, assesses risk factors, and teaches prevention, terminology, and other important factors.
When can false negative HIV tests occur?
During the window period
If the results of an HIV test are negative, what does this mean?
- Results are reported as negative
- Assess recent risks and encourage re-testing in 3 weeks, 6 weeks, 3 months
If an EIA test comes back positive, what should be done?
- Repeat the EIA test
- Results have to be confirmed with a Western Bloth or Immunofluorescence
What post-test counseling is important?
- Provide information in writing
- Provide resources
- Teaching
What teaching is helpful for post-test counseling?
- Effective Treatment
- Enhancing Immune System
- Preventing New Infections
- Testing Sexual Partners
What are common reactions to positive HIV test?
