Questions and CORRECT Answers
YELLOW TO BLUE - CORRECT ANSWER - Bromthymol blue indicator in reagent strip
pH produces a color change from ___ to ___ at pH 6.0-9.0
SODIUM NITROPRUSSIDE - CORRECT ANSWER - Reagent(s) incorporated in the
urine reagent strip for ketones
REFRACTOMETRY - CORRECT ANSWER - This urine specific gravity procedure
measures the velocity and the angle at which the light passes through a solution.
30 - CORRECT ANSWER - The value of clinically significant proteinuria if greater than
or equal to ___ mg/dL
FIRST MORNING SPECIMEN - CORRECT ANSWER - It is the best specimen for
urinalysis.
Bacteria - CORRECT ANSWER - Produces a uniformly dispersed cloudiness in the urine
which does not settle and cannot be filtered out
MOUSY - CORRECT ANSWER - What is the distinct odor of the urine from a patient
with phenylketonuria?
10 - CORRECT ANSWER - Reference value of urine protein should be less than ____
mg/dL.
between 15C and 38C - CORRECT ANSWER - Temperature at which refractometer is
calibrated
