d (Measure the total volume of the sample before 1) After receiving a 24 hr. urine for quantitative total protein analysis the
removing an aliquot. To calculate the total protein, technician must first:
measure the protein of an aliquot to learn the mg/dL. a. subculture the urine for bacteria
Then multiply that answer by the number of dL in the b. add the appropriate preservative
24-hour collection.) c. screen for albumin using a dipstick
d. measure the total volume
a (Urobilinogen is degraded by light.) 2) False results in the urobilinogen testing may occur if the urine specimen is:
a. exposed to light
b. adjusted to a neutral pH
c. cooled to room temp
d. collected in a nonsterile container

b (It is common practice to share samples between 3) A clean catch urine is submitted to laboratory for routine urinalysis and
the microbiology department and urinalysis. Ideally, culture. The routine urinalysis is done first, and 3 hrs. later, the specimen is
the culture is set up first to prevent contamination. If sent to the microbiology department for culture. The specimen should:
that is not feasible time wise, the sample should be a. be centrifuged, and the supernatant culture
aliquotted using aseptic technique, and refrigerated b. be rejected due to the time delay
until it can be cultured.) c. not be cultured if no bacteria are seen
d. be processed for culture only if the nitrate is positive
d (Bilirubin is degraded by light. The other analytes 4) Which of the following urine results is most apt to be changed by
will not be affected.) prolonged exposure to light?
a. pH
b. protein
c. ketones
d. bilirubin

c (Evaluate each statement. a is incorrect because 5) Urine samples should be examined within 1 hr. of voiding because:
these cells don't agglutinate. b is partially correct, but a. RBC's, leukocytes and casts agglutinate on standing for several hrs. at
urobilinogen decreases in light. c is true, bacterial room temp
overgrowth does lead to an alkaline urine. d is false, b. urobilinogen increases and bilirubin decreases after prolonged exposure
ketones are produced by fat metabolism in the to light
patient.) c. bacterial contamination will cause alkalinization of the urine
d. ketones will increase due to bacterial and cellular metabolism
b (Storage must inhibit bacterial growth but not kill 7) A urine specimen comes to the laboratory 7 hrs. after it is obtained. It is
the bacteria. Freezing and additives are not acceptable for culture only if the specimen has been stored:
acceptable. The most commonly used method of a. at room temp
preservation is refrigeration.) b. at 4 - 7 C
c. frozen
d. with a preservative additive
