MLT ASCP Practice Questions:
Urinalysis & Body Fluids
(T/F)
When the glucose result on a urine specimen from an little one is bad at the reagent strip, it can
be assumed that the specimen is negative for different reducing materials inclusive of galactose.
- ANS-False
The technique used at the reagent strip is unique for glucose. An additional test, along with
Clinitest, must be used to check for other lowering materials.
A forty one-year-vintage guy is admitted to the sanatorium complaining of a decreased
frequency of urination, a steady bloated feeling, weight benefit, and mild edema of the ankles
and eyes. Urinalysis consequences are as follows:
Color: light yellow
Clarity: clean
pH: five.0
Sp. Gravity 1.010
Glucose: 2+
Ketones: terrible
Protein- 3+
Blood: mild
Bilirubin: poor
Bacteria: bad
Urobilinogen: ordinary
Nitrate: terrible
**A huge quantity of white foam changed into cited.
Microscopic Results:
RBCs: zero-2
WBCs: 0-2
Casts: 2-5 hyaline, zero - 3 fatty casts, zero - 2 waxy casts
Few transitional epithelial cells
Few oval fats bodies
Based at the urinalysis document above, the MOST probable diagnosis is:
A. Acute pyelonephritis
B. Nephrotic syndrome
C. Acute glomerulonephritis
,D. Lipiduria of unknown etiology - ANS-B;
Nephrotic syndrome might satisfactory match the medical symtpoms and laboratory findings.
Nephrotic syndrome is resulting from damage to the kidneys, in particular the basement
membrane of the glomerulus; which causes bizarre excretion of protein and purple blood cells in
the urine. Fats are also present inside the urine in maximum cases. A foamy look of the urine is
a key characteristic of this condition.
Clinical signs consist of:
Swelling
Weight benefit from fluid retention
Poor urge for food
High blood stress
A sixty two-yr-old man drank an unknown liquid in a suicide try, and his urine contained crystals
similar in form to those proven in this image. This man MOST likely ingested:
A. Methanol
B. Isopropanol
C. Ethylene glycol
D. Ethanol
E. Rubbing alcohol - ANS-C;
The crystals which can be seen in the urine are monohydrate calcium oxalate crystals. Oxalic
acid, a byproduct of ethylene glycol metabolism, combines with calcium in the frame to form
monohydrate calcium oxalate crystals, as proven in the accompanying photograph.
A daily urine output which is over 2000 ml/24 hours is referred to as:
A. Anuria
B. Oliguria
C. Polyuria
D. Pyuria
E. Dysuria - ANS-C;
A every day urine output that's over 2000 ml/24 hours is referred to as polyuria. Polyuria is
related to at the least 2.5 liters of urine filtered consistent with day, resulting in profuse urinary
frequency and urination. Polyuria is a key function of diabetes mellitus that isn't under control.
A patient suspected of a urinary tract infection has a negative nitrite test, however bacteria are
gift upon microscopic exam. What can also have caused this discrepant end result? (Choose
ALL accurate answers)
A. The bacteria present aren't nitrate-reducers.
B. The urine specimen can also had been tested too quickly after series.
, C. The urine became no longer held inside the bladder for a enough amount of time for nitrate to
be reduced to nitrite.
D. The urine was in the bladder for more than four hours. - ANS-A & C;
When a urine sample indicates a terrible nitrite take a look at, however micro organism are
present upon microscopic examination, the false-poor result may be due to two possibilities
indexed within the selections above:
The micro organism that is gift isn't always a nitrate-reducer OR the urine changed into within
the bladder for an insufficient quantity of time for nitrate to be decreased to nitrite.
A positive leukocyte esterase check shows the presence in a urine specimen of which of the
following?
A. Lymphocytes
B. Granulocytes
C. Erythrocytes
D. All of the above - ANS-B;
Leukocyte esterase is an enzyme found in maximum granulocytic white blood cells (WBCs).
When the range of granulocytes inside the urine will increase extensively (more than 0-2 in step
with area), this screening test pad turns into positive at the chemical reagent strip.
A technologist is having problem differentiating between red blood cells, oil droplets and yeast
cells on a urine microscopy. Acetic acid need to be brought to the sediment to:
A. Lyse the yeast cells
B. Lyse the crimson blood cells
C. Dissolve the oil droplets
D. Crenate the purple blood cells - ANS-B;
Acetic acid can be introduced to urine samples that allows you to lyse red blood cells and go
away the remaining sediment in tact. This is useful whilst attempting to distinguish between
purple cells, yeast, or fats droplets. Once the red cells are lysed, polarized light can help to
differentiate yeast from oil droplets, as oil or fat droplets will refract with a function maltese cross
shape.
A urine manufacturing of less than four hundred mL/day is:
A. Consistent with normal renal function and water stability
B. Termed isosthenuria
C. Defined as oliguria
D. Associated with diabetes mellitus
E. As a result of mild dehydration - ANS-C;
Oliguria is described because the manufacturing of a reduced quantity of urine. This can be
described as a daily urine production of much less than 400 mL.
