6) The following results were B
obtained on a urine specimen at
8:00
AM:
pH: 5.5; protein: 2+; glucose: 3+'
ketones: 3+; blood: negative;
bilirubin: positive; nitrite: positive
If this urine specimen was stored
uncapped at 5C without
preservation and retested at 2PM,
which of the following test results
would be changed due to these
storage conditions:
a. glucose
b. ketones
c. protein
d. nitrite
,9) A 24-hour urine from a man D
who
had no evidence of kidney
impairment was sent to the
laboratory for hormone
determination. The volume was
600
mL, but there was some question
as
to the completeness of the 24-hour
collection. The next step would be
to:
a. perform the hormone
determination, since 600 mL is a
normal 24-hour urine volume
b. check the creatinine level; if it is
<1g, do the procedure
c. report the hormone
determination
in mg/dL in case the specimen
was
incomplete
d. check the creatinine level; if it is
>1g, do the procedure
11) eGFR calculated by the MDRD C
formula takes into account the
age,
BUN, age, race, albumin and what
else for its calculations?
a. urea
b. ammonia
c. creatinine
d. cystatin C
, 16) An ammonia-like odor is C
characteristically associated with
urine from patients who:
a. are diabetic
b. have hepatitis
c. have an infection with Proteus
sp
d. have a yeast infection
18) Acid urine that contains C
hemoglobin will darken on
standing
due to the formation of:
a. myoglobin
b. sulfhemoglobin
c. methemoglobin
d. red blood cells
25) A urine specimen collected on D
an apparently healthy 25-year-old
man shortly after he finished
eating
lunch was cloudy but showed
normal
results on a multiple reagent strip
analysis. The most likely cause of
the
turbidity is:
a. fat
b. white blood cells
c. urates
d. phosphates
