Practice Questions: Questions and
Answers (100% Pass)
The indicator(s) used in the pH test region of the chemical reagent strips for
urine is/are: (Choose ALL correct answers)
A. methyl red
B. methyl blue
C. bromothymol blue
D. bromothymol red
✓ A & C;
✓ The indicator(s) used in the pH test region are methyl red and
bromothymol blue. Typically on most chemical reagent strips for urine
pH, with an increase in urinary pH, the indicators bromothymol blue
and methyl red, changes from orange to green and blue.
Which of the following is not a standard method for measuring the specific
gravity of urine:
A. Urine reagent strips

B. Freezing point depression
C. Refractometry
D. Hydrometry
✓ B;
✓ Osmolality can be measured by freezing point depression, but not
specific gravity as specified in this question. The other methods are
used to measure specific gravity in urine samples.
The normal range for urine pH is:
A. 4.6 to 8.0
B. 5.0 to 6.0
C. 5.5-6.6
D. 7.35-7.45
✓ A;
✓ Normal urine pH varies from 4.6 to 8.0. After meals, urine becomes more
alkaline due to gastric acid secretion (alkaline tide). At night due to
shallow breathing, it becomes more acid. A high meat diet results in a
more acid urine than a vegetarian diet, due to excretion of
phosphates and sulfates.

Which two of the following crystalline elements are found in acid urine:
A. Cystine
B. Triple phosphate
C. Calcium phosphate
D. Tyrosine
✓ A & D;
✓ Crystals and sediment found in acid urine include: cystine, leucine,
calcium oxalate, sodium urate, sulfonamide, tyrosine, uric acid, and
amorphous urates.
False-positive tests for protein on a urine reagent strip may be caused by:
(Choose ALL of the correct answers)
A. Bacterial contamination
B. Urine that has remained at room temperature for an extended period of
time
C. Alkaline medication
D. Ascorbic acid

✓ A-C;
✓ Bacterial contamination, urine that has remained at room temperature
for an extended period of time, and the presence of alkaline
medication are all factors which can cause false positives on the
protein pad of a urine reagent strip.
Bence-Jones proteinuria can be seen in all of the following conditions
except:
A. Amyloidosis
B. Nephrotic syndrome
C. Multiple myeloma
D. Macroglobulinemia
