Questions and Answers (100% Pass)
A patient with uncontrolled diabetes mellitus will most likely have:
✓ pale urine with a high specific gravity
While performing an analysis of a baby's urine, the laboratorian notices the
specimen has a "mousy" odor. What substance that is excreted produces this
odor
✓ Phenylpuruvic acid
An ammonia-like odor is characteristically associated with urine from
patients who:
✓ have an infection with Proteus spp.
Urine that develops a port wine color after standing may contain:
✓ porphyrins
Acid urine that contains hemoglobin will darken on standing due to the
formation of

✓ methemoglobin
Irvine from a 50-year-old man was noted to turn dark red on standing. This
change is cause by the presence of
✓ Porphyrins
The clarity of a urine sample should be determined
✓ following thorough mixing of the specimen
Milky urine from a 24 year old woman would most likely contain
✓ many white blood cells
A brown-black urine would most likely contain:

The yellow color of urine is primarily due to
✓ urochrome pigment
Red urine may be due to:

✓ myoglobin
A urine specimen collected on an apparently healthy 25-year-old man
shortly after he finished eating lunch was cloudy but showed normal results
on multiple reagent test strip analysis. The most likely cause of this turbidity is
✓ Phosphates
In what metabolic disease will urine turn dark brown to black upon standing
✓ Alkaptonuria
Urine osmolality is related to:
✓ specific gravity
Urine Specific Gravity is an index of the ability of the kidney to

A patient urine sample has an increased protein and a high specific gravity.
Which of the following would be a more accurate measure of urine
concentration
✓ osmolality
To prepare a solution appropriate for quality control of the refractometer the
laboratory should use
✓ Sodium chloride with a specific gravity 1.022
A urine's specific gravity is directly proportional to its:
✓ dissolved solids
Isosthenuria is associated with a specific gravity which is usually
✓ fixed around 1.010
the fluid leaving the glomerulus has a specific gravity of
✓ 1.010 (pH of 7.4)
