2025 Medical Interventions Final Answers
1.Select the best description of a medical intervention.: Any measure
whose purpose is to improve health or to alter the course of a disease.
2.Polymerase chain reaction consists of cycles. Each cycle has how
many steps?: 3 steps
3.Disease detection using bioinformatics depends upon properly
sequencing the DNA of the pathogen, but sometimes things go wrong in the
lab. If the necessary flourescent markers were not added properly, that
would lead
to which of the following results?: The sequence of nucleotides could not
be determined as the genetic material passed through the laser.
4.In order to obtain quantitative results from an ELISA test, what tool can
be created for comparative analysis and what factor is being analyzed?:
serial dilution, color intensity
5.You are an immunologist who has 3 different patients suspected of
having systemic lupus erythematosus disease. Below are the results of an
ELISA test done on the patients' blood. Which patient has the highest
concentration of antibodies in his or her sample?: Patient C has the
highest concentration of antibodies
6.Carlos has come in feeling tired and sore, but refuses to submit to
molecular testing. He has a class with Maria and Darien and is dating
Jennifer. Just a few days ago Carlos and Jennifer were caught making out in
the hallway. Which of the four diseases does he most likely have?:

, 7.Penicillin is an antibiotic that inhibits enzymes from catalyzing the
synthe- sis of peptidoglycan, so which prokaryotes should be the most
vulnerable to inhibition by penicillin?: gram-positive bacteria
8.In attack of the super bugs E. coli I with chromosomal DNA coding resis-
tance to streptomycin was cultured with E. coli II that contains ampicillin
resistance located on the plasmid DNA. As the cultures grew which of the
following occured?: DNA from E. coli II was passed to E. coli I causing
ampicillin resistance in E. coli I.
9.Imagine that you are sick with pneumonia caused by a bacterial infection.
Your doctor prescribes an antibiotic to be taken every day for eight days.
What do you expect to happen if two doses are skipped?: Weakly resistant
bacteria will die off, some moderately and extremely resistant bacteria
will be killed off, but the infection will remain and you will remain sick or
may even get worse.
10.Does a cochlear implant work the same for all patients?: No. Each
person has to learn how to interpret the signals that their brain
receives.
11. There has been some speculation as to whether or not parents
should have the right to choose to vaccinate their child. All of the following
are examples
of benefits of vaccination EXCEPT: A child's immune system can be
"overloaded" if the child receives multiple vaccines at once.
12.Bacteria that contain the plasmid, but not the eukaryotic gene, would
grow (long question): in all four types of broth
13.Restriction enzymes are found in almost all bacterial species, and their
