Medical interventions unit 1.1 questions

which of these is not a medical intervention?

all of these are medical interventions (urine test, bandages, CT scans or also called cat scan)

what is an outbreak?

A sudden rise in the incidence (number of sick people) of a disease

What is a pathogen?

A specific causative agent of a disease, like a virus, bacteria, mold, prion

Which disease is transmitted via a virus?

influenza

Which of these diseases is transmitted via bacteria?

strep throat

Symptoms include chills and a fever, malaise/fatigue, headache, and a stiff neck.

meningitis

A patient comes to the doctor complaining of yellowing of the skin (jaundice) and a skin rash. They report that they've been very tired for several days and have a sore throat that is getting worse. The doctor discovers that the lymph nodes in the armpits are swollen along with the neck lymph nodes. Palpation reveals a tender abdomen and probable enlarged spleen. What is it likely that the patient has?

mononucleosis

A few days ago, a patient felt fine, then rapidly started feeling sick. They first noticed a headache, then a runny nose. For the last few days, they've had a persistent cough, have been very tired, and report a severe headache and overall body soreness. They're running a fever which has reached 104F on occasion, and have frequent chills. What did they catch?

influenza

A child has a low but consistent fever and complains of a sore throat. They've had an upset stomach, and the doctor finds that the lymph nodes are very swollen. When looking at the throat, it is very red and there are some whitish patches. What did the child catch?

strep throat

A patient just generally feels lousy. She's got a runny nose and sore throat, the occasional cough, and her temperature has been hovering around 100F the last few days. She's tired and grumpy and just really, really wants to be able to breathe through her nose again. What did she catch?

common cold

can the disease Sue had be prevented via vaccine?

Yes, and it’s very effective

Why is the PCR used in the process of genetic sequencing?

To make enough copies of the DNA that it can be tested and measured

The gel electrophoresis was used with pieces of DNA of different lengths. What was at the end of each DNA fragment?

A fluorescently tagged nucleotide

What does BLAST do in this lab?

compared the DNA sequence you enter to known DNA sequences

the field of science that combines biology, computers, and information technology to store and analyze genetic data

bioinformatics

Each colored peak on this graph represents

a different nucleotide

What pathogen was identified using BLAST

neisseria meningitidis

an organism’s genes, its genetic material

genome

What sort of BLAST did we use?

nucleotide blast

What disease did they discover Sue had?

Meningitis (meningococcal)

Steps of one PCR cycle in order:

1. denaturing

2. annealing

3. extension/elongation

What letter(s) is/are used to represent an unknown piece of DNA, where nucleotides aren’t clear?

N
