All of the following systems may be used to measure the specific
gravity of urine: - ANSWERS-Refractometer, harmonic oscillation, or
reagent test strip
All of the following systems may be used to measure the specific
gravity of urine EXCEPT: - ANSWERS-Hydroelectric focusing
What is the best single indicator of renal disease? - ANSWERS-
Proteinuria
All of the following apply to the dipstick test for urine protein
estimation by the dipstick method, based on the protein error of
indicators, EXCEPT which one? - ANSWERS-The color change on
the dipstick is due to the pH change
All of the following apply to the dipstick test for urine protein
estimation by the dipstick method, based on the protein error of
indicators: - ANSWERS-Most of the indicator is in the non-iodized
form, the protein will combine with the non-iodized form of the
indicator, and protein combined with the indicator changes into the
ratio of ionized and non-iodized forms.
Which of the following does NOT apply to urine protein estimation
by the dipstick method? - ANSWERS-Bence-Jones protein interferes
with the measurement of albumin
,All of the following apply to urine protein estimation by the dipstick
method? - ANSWERS-Highly alkaline buffered urine can cause a
false positive result, the principle of the test is the protein error of
indicators, the test is more sensitive to albumin than to globulin.
Which of the following is true of the detection of urinary glucose? -
ANSWERS-Any reducing substance can give a false positive reaction
with the copper reduction method for glucose
The urine dipstick test for occult blood depends on which fact? -
ANSWERS-Hemoglobin can act as a peroxidase
Which of the following statements is NOT true? - ANSWERS-In a
urine culture, 10^2 microorganisms/mL of urine is considered
significant
The following statements about urine cultures are true: - ANSWERS-
A clean catch urine is preferable, in most instances, to a catheterized
specimen, the presence of bacteria in the uncentrifuged specimen of
urine collected under controlled conditions is associated with a
significant colony count, and the presence of bacteriuria can be
recognized by a positive nitrite result.
Red blood cells in the urine may be confused with all of the following
EXCEPT which one? - ANSWERS-Cholesterol crystals
, RBCs in the urine may be confused with the following: - ANSWERS-
Oil droplets, yeast cells, and calcium oxalate crystals
Which statement does NOT apply to WBCs in the urine sediment: -
ANSWERS-WBCs in the urine must be accompanied by proteinuria
The following statements apply to WBCs in the urine sediment: -
ANSWERS-A few WBCs may be present in normal urine, WBCs in
urine appear spherical and granular, an increase in WBCs is
associated with an inflammatory process.
WBCs are frequently seen in patients with urinary tract infections.
What type of WBC is seen most frequently in the urine sediment? -
ANSWERS-Neutrophils
A glitter cell is a term used to describe a specific type of which one of
the following? - ANSWERS-Leukocyte
Vaginal contamination may be responsible for the appearance of
which element in the urine from a female patient? - ANSWERS-
Squamous epithelial cells
The matrix of urinary casts has been identified as which protein? -
ANSWERS-Tamm-Horsfall mucoprotein
Casts are formed primarily in which portion of the kidney? -
ANSWERS-Distal convoluted tubule
