URINALYSIS: WORKSHEET
The primary objectives of this worksheet are
to report and explain the results of the urinalysis laboratory.
1. Analysis of your own urine sample:
a. What was the pH of your urine?
b. What was the specific gravity of
your urine at the beginning of class?
(Indicate if
you were dehydrated or maximally hydrated before class.)
c. What abnormalities (if any) did you
observe in your urine sample?
2. Analysis of an unknown urine sample:
a. Which unknown did you test?
b. What abnormalities (if any) did you observe
in the unknown sample?
3. Complete the following table, comparing the average specific gravities
and
urine volumes from each of the five
treatment groups.
| Group | Treatment | Average Specific Gravity | Average Urine
Volume (ml) |
|||
| Initial | 1 Hour | 2 Hour | 1 Hour | 2 Hour | ||
| A | Control | |||||
| B | Hydrated | |||||
| C | Isotonic | |||||
| D | Dehydrated | |||||
| E | Maximally
Hydrated |
|||||
4. Select one group which was different from control and briefly
explain the mechanism
by which the urine solute concentration was
altered.
