a pale urine with a high specific gravity - correct answer A patient with uncontrolled diabetes
mellitus will most likely have:
a pale urine with a high specific gravity
b concentrated urine with a high specific gravity
c pale urine with a low specific gravity
d dark urine with a high specific gravity
a phenylpyruvic acid - correct answer While performing an analysis of a baby's urine, the
laboratorian notices the specimen has a "mousy" odor. Of the following substances that may be
excreted in urine, the one that most characteristically produces this odor is:
a phenylpyruvic acid
b acetone
c coliform bacili
d porphyrin
c have an infection with Proteus spp. - correct answer An ammonia-like odor is
characteristically associated with urine from patients who:
a are diabetic
b have hepatitis
c have an infection with Proteus spp.
d have a yeast infection
b porphyrins - correct answer Urine that develops a port wine color after standing may contain:
a melanin
b porphyrins
c bilirubin
,d urobilinogen
c methemoglobin - correct answer Acid urine that contains hemoglobin will darken on standing
due to the formation of:
a myoglobin
b sulfhemoglobin
c methemoglobin
d red blood cells
b porphyrins - correct answer Urine from a 50-year-old man was noted to turn dark red on
standing. This change is caused by:
a glucose
b porphyrins
c urochrome
d creatinine
b following thorough mixing of the specimen - correct answer The clarity of a urine sample
should be determined:
a using glass tubes only; never plastic
b following thorough mixing of the specimen
c after addition of sulfosalicylic acid
d after the specimen cool to room temperature
b many white blood cells - correct answer Milky urine from a 24 year old woman would most
likely contain:
a spermatozoa
b many white blood cells
c red blood cells
,d bilirubin
c melanin - correct answer A brown-black urine would most likely contain:
a bile pigment
b porphyrins
c melanin
d blood cells
a urochrome pigment - correct answer The yellow color of urine is primarily due to:
a urochrome pigment
b methemoglobin
c bilirubin
d homogenistic acid
C. myoglobin - correct answer Red urine may be due to:
A. bilirubin
B. excess urobilin
C. myoglobin
D. homogenistic acid
d phosphates - correct answer A urine specimen collected on an apparently healthy 25 y/o man
shortly after he finished eating lunch was cloudy but showed normal results on a multiple
reagent test strip analysis. The most likely cause of the turbidity is:
a fat
b white blood cells
c urates
d phosphates
, b alkaptonuria - correct answer In which of the following metabolic diseases will urine turn dark
brown to black upon standing?
a phenylketonuria
b alkaptonuria
c maple syrup disease
d aminoaciduria
c specific gravity - correct answer Urine osmolality is related to:
a pH
b filtration
c specific gravity
d volume
b concentrate the urine - correct answer Urine specific gravity is an index of the ability of the
kidney to:
a filter the plasma
b concentrate the urine
c alter the hydrogen ion concentration
d reabsorb sodium ions
A. dissolved particles including ions - correct answer Osmolality is a measure of:
A. dissolved particles including ions
B. undissociated molecules only
C. total salt concentration
D. molecule size
