Scribe Post April 30th

Today In Class:
Stamped UP 13-17
Urinalysis Lab UP 27-38
Went over UP 10-11 and 13-17
Got a study guide ch 21
In this lab we analyzed 4 different urine samples, to compare them to the "ideal urine". By performing different tests on the urine samples, we had to identify what conditions the patients had. For example, glucose in the urine = diabetes.
Physical Characteristics: we observed the urine

Sample     Color             Clarity                                                           Scent            pH
Patient 1=neon yellow        All were clear ex. patient 3 was cloudy    no scent                6
Patient 2=Light Orange                                                                    smokey scent       4
Patient 3=pale yellow                                                                         sour scent         7
Patient 4= Neon-ish yellow                                                              nothing                 7

Benedict's Test (for sugar)- heated the urine samples with Benedict solution
Before heating:           Color after heating                                              Results (+/-)                                      
all were blue/green     All same as before except Patient 1 was red brown         All - except patient 1 is +
Patient 1 has glucose in urine

Biuret Test (for proteins)-added Biuret solution to the urine samples and examined a color change
Initial Colors                                    Final Color                                      Results
(see physical characteristics chart)     All green except Patient 2 is orange     all - except Patient 2 is +
Patient 2 has protein in urine

We did not get to the microscope part

Page 11:
1. I
2. J         the collecting tubule
3. K (proteins are BIG)
4. E
5. J      no sugar in collecting tubule or else its diabetes
6. D     proteins are BIG

Kidney Dialysis

There is salt in dialysis bag, not in cup. After, there is salt in the bag, not in the cup. Color of the bad is red, the water is clear. After the bag is still red, but the water is yellow.

1. The bag is the circulatory system. The salt is the blood cells. The waste from the blood is emptied into the cup, the nephron. The salt, blood cells do not get through because they are too big. There shouldn't be blood in the urine
2. Kidneys are like water treatment plants because they filter the solution and pump it back cleaned.
3. Kidneys also are red blood cells producers, and they regulate blood pressure and calcium levels.
4. Urine can be analyzed to determine the condition of a patient. For ex. glucose in urine means diabetes.
5. The blood stays in the circulatory system in a normal kidney. Ammonia goes into the nephron and is excreted as urea.
6. Land animals are constantly losing water.... ( can anyone add?)
