Bleach in the collecting bottle
,Substances found in urinary sediment that are more easily distinguished by use of
polarized microscope are:
Give this one a try later!
Lipids
Parasites which can be found in urinary sediment include all of the following EXCEPT:
Give this one a try later!
Plasmodium malariae
Plasmodium malariae is the only parasite that is listed that could NOT
potentially be seen in urine sediment. Plasmodium is a blood parasite.
Both Enterobius vermicularis and Trichomonas vaginalis could potentially
arrive in the urine as contaminants from other sources; Enterobius from
fecal contamination and Trichomonas from vaginal secretions. Of the
parasites that are listed, only Schistosoma haematobium is a true urinary
tract parasite.
A urine specimen was collected at 6:00 a.m. and remained at room temperature until it
was received in the laboratory at 3:30 p.m. How may the pH of the specimen be
affected by the extended time at room temperature if bacteria are present in the
specimen?

, The pH may become more alkaline.
Which of the following tests included on a urine reagent strip would never be
reported out as negative?
Give this one a try later!
Urobilinogen
Which of the following cells are considered abnormal and clinically significant on a
CSF differential?
Give this one a try later!
- Blast cells
- Malignant cells
The indicator(s) used in the pH test region of the chemical reagent strips for urine
is/are:
Give this one a try later!
- Methyl red
- Bromothymol blue
, Which of the following statements are TRUE regarding storing and handling of
chemical reagent strips if you are using a manual method (visually reading the reagent
strip)?
Give this one a try later!
- Compare strip to color chart to check for correlating color.
- Handle strips at end away from test area.
Abnormal crystals that can be found in urine include:
Give this one a try later!
- Leucine
- Tyrosine
- Cystine
If the crystals are from solutes that are not normally in the urine, they are
considered "abnormal." Abnormal crystals may indicate an abnormal
metabolic process. Some of these include: Cystine, tyrosine, and leucine.
The image is a Wright-Giemsa stained smear (1000x) of cerebrospinal fluid (CSF). The
arrows point to cells that may indicate which of the following conditions?
