following tests?
a. Pregnancy testing
b. Culture for possible UTI
c. Qualitative protein determination
d. All are correct
ANS: D

2. Casts in a urine specimen develop in what part of the urinary tract?
a. Urethra
b. Kidney
c. Bladder
d. Ureters

3. If a urine specimen cannot be analyzed within 1 hour, the best course of action is to:
a. discard the specimen and order a recollection.
b. refrigerate the specimen.
c. add a chemical preservative.
d. let it remain at room temperature.

4. A cloudy urine specimen may be the result of which of the following?
a. Glycosuria
b. Ketones
c. Lipids

a. Bleeding in the urinary tract
b. Liver disorder
c. Pseudomonas infection
d. Diabetes

6. Urine suspected of having high levels of which substance should be stored in a dark place
before testing?
a. Sugar
b. Red blood cells
c. Bacteria

7. Which statement is true about the pH of urine?
a. The average pH of freshly voided urine is 9.
b. The urinary pH varies with the diet.
c. The urine pH is alkaline if the patient has bacteriuria.
d. A urine pH below 7 indicates alkalinity.
ANS: C
With gross bacteriuria, the urine pH is alkaline as a result of bacterial conversion of urea to
ammonia.
