U. R. in TROUBLE!

Background: The big job of the kidney is to maintain(homeostasis), chemical equilibrium, of the body, by filtering the blood that circulates through it. The Kidney converts what's leftover into urine. About 2000 L of blood pass through both kidneys a day, yet only 1.5 -2 L exit. That contains all of the liquid waste that needs to be eliminated.

Scenario:

You are a clinical technician (lab tech). Several urine samples have arrived at the laboratory and the labels have become separated from the samples. You have the patient's names and probable diagnosis on the labels. Design an experiment to match the unknown samples with their owners.

Patient #: Symptoms

Patient #

Potential disorders based on office visit:

Colonel Mustard

Jaundice from liver damage or kidney stones

Mrs. Peacock

Bladder Infection or kidney damage

Professor Plum

Diabetes or kidney damage



Laboratory Tests:

Test

Indicator used to test urine

Normal ranges and other information (your lab group needs to research)

pH

pH paper


protein

Biurets


glucose

glucose test strips


broken blood cells

color


specific gravity

urinometer- or called hydrometers


Bile

shaking test-tube


RBC:

slide examination (preprepared)


salt crystals

slide examination (preprepared)


Prelab:

1. Hypothesis, Null hypothesis, SV, IV, DV, Control

2. Write out the procedures you intend to use.

3. Design a data table.

Lab Analysis: Post Lab Questions and Write up requirements: (30 points) *** if you were absent see below for your make up assignment.

(include a full title for the lab) 1 point

1. Go to Labs Online and read the overview on the kidney, write a paragraph on the function of the kidney and the excretory system. (3 points)

1. Include a data table of the information gathered during the laboratory. Make sure there is only one horizontal line between the column headings and the data. (Hint, make your data table in a spreadsheet like EXCEL). The data table needs a full title. Include any units for the tests done (example, glucose test strip is in mg/dL). (3 points)

2. In your lab group discuss and match the patients to the urine samples. Provide your rationale for matching each urine (1-3) to each patient (A-C) using a table format. (9 points).

Example:

Patient Name:

Urine #

Rationale (urine contains "x" which indicates the disease is most likely....)

1.

2.

3.



2. Using an outside source, i.e.. internet, medical dictionary,  (NOTE: if you copy and paste information you will receive a ZERO on this assignment) use your own words and define all technical vocabulary and reference everything you use. Make sure you remember to avoid all pronouns, make sure if you use the word "this" a noun generally follows; example "This result..."  You will create 3 paragraphs (one for each patient). (12 points – 4 points per paragraph)

A. describe the major symptoms of each diagnosed disease (in sentences).

B.  explain (in your own words and using no pronouns) why the urine lab tests are appropriate and how the test can indicate the presence of one of the conditions/diseases.

C.  explain what are the recommendations for treatment of that condition (in your own words with no pronouns). Also make sure that all scientific terminology is explained after you first use the word.... example "urinalysis (a test of substances found in urine)2 (note the superscript 2 for the reference).

*** If you were absent on the day of the lab do the following alternative assignment, please make sure you label your paper Alternative Assignment for UR in Trouble.

Go to: Labs Online (read the overview, watch the video link on the bottom, press next for the next page, read about diseases, choose three of the diseases).

Write a one page reflection/summary of what you have learned about the 3 diseases (background, symptoms, tests, and treatments). Include any other “reputable web sites” (university, government, educational sites) that you used.
