Medical Interventions EOC exam with
correct answers
medical intervention - 🔷ANSWERS ✔✔🖊a measure that is taken to improve health or
change the direction of how the disease progresses
What are the main categories of interventions that function to maintain human
health? - 🔷ANSWERS ✔✔🖊preventive, pharmaceutical, and surgical
How do scientists gather evidence during the potential outbreak of an infectious
disease? - 🔷ANSWERS ✔✔🖊Scientists gather potential outbreaks using bioinformatics.
What is bioinformatics? - 🔷ANSWERS ✔✔🖊Bioinformatics is collecting, classifying,
storing,
and analyzing information.
How can DNA sequences be used to identify disease pathogens? - 🔷ANSWERS 🖊
✔✔DNA sequences are ran through a website or BLAST. The DNA is compares the
sequence to the human genome.
What is an antibody? - 🔷ANSWERS ✔✔🖊An antibody is what responds to the immune
response that is the antigen. The primary antibody binds with the specific antigen
during ELISA.
How do antibodies identify and inactivate antigens? - 🔷ANSWERS ✔✔🖊Antibodies
identify the antigens through their immune response. The antigens are inactivated
when they bind together.
How can an ELISA assay be used to detect disease? - 🔷ANSWERS ✔✔🖊An ELISA
assay is used to bind a primary antibodies to a specific antigens. Next, an enzyme-
linked secondary antibodies binds to the primary antibodies. Then, substrates are
added. If the enzyme combines with the substrate, the solution turns blue. This shows
there is a pathogen.

What is bioinformatics? - 🔷ANSWERS 🖊✔✔ Bioinformatics is collecting, classifying, storing, and analyzing information. How can DNA sequences be used to identify disease pathogens? - 🔷ANSWERS 🖊 ✔✔DNA sequences are ran through a website or BLAST. The DNA is compares the sequence to the human genome.

This shows there is a pathogen.

Why is it important for doctors to know the concentration of disease antigen present in a patient's system? - 🔷ANSWERS 🖊✔✔ The doctors need to know the concentration of the disease to know how progressed the disease is and how much of the medical intervention is needed. The doctors can use a solvent to dissolve a solute to form a solution. Then do a serial dilution to get to the point where it will kill the pathogen. What steps do scientists take to diagnose, treat, and prevent future spread of a disease outbreak? - 🔷ANSWERS 🖊✔✔ The scientists would perform ELISA assays and determine the cause of the disease to help prevent the spread of disease and an outbreak. How do antibiotics work to treat bacterial infections? - 🔷ANSWERS 🖊✔✔ Antibiotics kill foreign bacteria in the human body to eliminate contamination from the human body. There are four different kinds of antibiotic and they each do something different to kill the bacteria. Penicillin - 🔷ANSWERS 🖊✔✔ disrupt making the bacterial cell wall Tetracycline - 🔷ANSWERS 🖊✔✔ prevent attachment of RNA to ribosomes, prevents protein production Fluoroquinolone - 🔷ANSWERS 🖊✔✔ separates the DNA strands, prevent DNA replication Sulfonamide - 🔷ANSWERS 🖊✔✔ prevents the production of folic acid, the building block of DNA What methods do bacteria use to share antibiotic resistance? - 🔷ANSWERS 🖊✔✔ There are 3 different ways bacterial cells share resistance :

  • Transformation: when one bacterium take DNA from a dead bacterium
  • Conjugation: "cell sex" bacteria is in direct contact with another and the genetic material is transferred.

What are vaccinations? - 🔷ANSWERS 🖊✔✔ • A vaccination or inoculation is the procedure by which a vaccine is given.

  • A mixture which is given to stimulate the bodies immune system thus creating antibodies. Vaccines warn the body that a disease may come so it can prepare for it. How does a vaccine activate the body's immune system? - 🔷ANSWERS 🖊✔✔ Your immune system is able to recognize foreign invaders by antigens. So in response the body make antibodies to fight the foreign invaders. How have vaccinations impact disease trends in our country? - 🔷ANSWERS 🖊 ✔✔Reduced the number of people that die from epidemics. We don't have thousands of people dying from polio and the common flu.
  • How ever if enough of our community are vaccinated then others will not get sick that's called herd immunity. What are methods used to produce vaccines in the laboratory? - 🔷ANSWERS 🖊 ✔✔There are 6 ways for a vaccine to be made in the laboratory they are, killed, similar pathogen, toxoid, subunit, live attenuated, naked DNA. Killed- Polio Similar pathogen- small pox Toxiod- Tenatus Subunit- Hepatitis B Live Attenuated-Measels Naked DNA- AIDS What is recombinant DNA technology? - 🔷ANSWERS 🖊✔✔ Recombinant DNA technology: Is the combining of two different species' DNA into a host organism to make new genetic combinations. What are the molecular tools used to assemble recombinant DNA? - 🔷ANSWERS 🖊 ✔✔- Plasmids
  • Vectors or in this case bacteria
  • Restriction enzymes
  • DNA ligase
  • Nutrient agar How can recombinant DNA and bacterial cells be used to produce vaccines? - 🔷ANSWERS 🖊✔✔ For example Naked DNA vaccines use genes from the pathogen. Then it goes through PCR, the gene with the vector is added, bacteria is added to allow vector replication. After that it goes through purification. Your immune system will have a reaction and it is less risky because the virus can't replicate. How can engineered plasmids be inserted into bacterial cells? - 🔷ANSWERS 🖊 ✔✔Restriction enzymes cut the plasmid and then inserts the engineered plasmid and is then put back together with DNA ligase which is basically super glue. What is epidemiology? - 🔷ANSWERS 🖊✔✔ deals with the incidence, distribution, and control of disease in a population How can epidemiologists assist with the detection, prevention, and treatment of both chronic and infectious disease? - 🔷ANSWERS 🖊✔✔ Epidemiologist use studies (case- control and cohort)
  • Case-Control Study: Where a group of people with the diseases are compared to people without the disease
  • Cohort Study: A study where a group of people that have been exposed to a disease and people that haven't been exposed are followed to see the determines the incidence of a disease. What is genetic testing? - 🔷ANSWERS 🖊✔✔ A type of testing to see if a person has a genetic disorder or may be a carrier. Genetic engineers use the sequencing of human DNA in order to discover genetic differences, anomalies, or mutations that may prove scientific. What are the duties of a genetic counselor? - 🔷ANSWERS 🖊✔✔ Genetic counselors provide information and support to families who have members with birth defects or
