PLTW Medical Interventions Final Exam ALL
QUESTIONS AND CORRECT ANSWERS ||BRAND NEW
VERSION!!
What is a medical intervention? - ANSWER-Any measure
whose purpose is to improve health or alter the course of
a disease
What are the main categories of interventions that function
to maintain human health? - ANSWER-Treatments,
Diagnostics and Equipment
,How do scientists gather evidence during the potential
outbreak of an infectious disease? - ANSWER-1. Record
patient's symptoms and find similarities with other patients
2. Isolate the bacteria in a lab
3. Go to affected areas and determine the origin of the
disease
4. Identify the disease using DNA sequencing since
pathogens alter certain DNA sequences
What is bioinformatics? - ANSWER-The collection,
classification, storage, and analysis of biochemical and
biological information using computers. (Especially applied
in molecular genetics and genomics)
,How can DNA sequences be used to identify disease
pathogens? - ANSWER-You can observe mutations and
abnormalities that disease pathogens have
What is an antibody? - ANSWER-A blood protein in the
body produced by B-cells (B-Lymphocytes) that fight
against a foreign substance by recognizing a specific part
of it.
How do antibodies identify and inactivate antigens? -
ANSWER-1. Shape recognition
2. Proteins of the antigens are configured to specific
antibodies, so the foreign antigens bind to the specific
antibodies that inactivate them
, How can the ELISA assay be used to detect disease? -
ANSWER-1. Primary antibodies attach to specific antigen
2. Secondary antibody attaches to primary antibody
3. When enzyme substrate is added, color change occurs
Why is it important for doctors to know the concentration
of the disease antigen present in a patient's system? -
ANSWER-Higher concentration = closer to patient zero
Patient Zero - ANSWER-The first person to be infected
with a particular disease
