Urinalysis and Body Fluids Chapter 1
& 2 Exam |66 Q’s and A”s
OSHA - -This agency regulates safety and will be the one that will come in to
investigate and give fines for all the safety practices you are not following.
- Standard Precautions - -Are currently in force as they cover washing our
hands after glove removal as well as treating all body fluids as infectious.
- Biological Hazards example - -Spilling a bloody urine specimen which gets
on your jeans because you hadn't buttoned your lab coat all the way.
- Best way to protect yourself from a possible aerosol - -Uncapping a tube
behind a shield and placing a Kim Wipe on the stopper when removing it.
- Fomite - -Mosquito
- To protect yourself from biohazards, your gloves should be tucked under
the cuff of your lab coat. - -False
- I am working with a chemical that has a symbol on it containing the colors
red, white, blue and yellow. The numbers given for each color are:
yellow = 0, red = 0, blue = 4 and no special instructions found in the white
box. What type of hazard should I be concerned with while working with this
chemical? - -Chance of respiratory tract damage if it is breathed in.
- I need a dilute HCl solution. I am preparing it from concentrated HCl acid.
How should I go about preparing this safely? - -Always add acid to the water.
- Urea - -This substance makes up approximately 2.5% of the urine
specimen.
- Test results on a urine specimen show it to be colorless with a specific
gravity of 1.035. What condition do you suspect the patient might have? - -
Diabetes Mellitus
- What change will occur with protein present in the urine specimen that sits
for over 2 hours? - -Stay the same
- Hypersthenuric - -A urine specimen that is 1.028
- What type of urine will cells be most likely to lyse in? - -Dilute and alkaline
, - Accepting a urine specimen contaminated with feces could result in what
type of error? - -Pre-Analytical
- Glycolysis - -Glucose has broken down in a specimen
- This is the best specimen to collect if you want to make sure you will
detect the substance you are looking for - -First morning
- Which type of specimen requires that a chain of custody is kept? - -Drug
Screen
- A male patient is collecting 3 specimens to check for prostatitis. The
results are as follows:
Container 1 = 50 WBC
Container 2 = 50 WBC
Container 3 = 50 WBC
What will be your determination from these results? - -We don't know if the
patient has prostatitis as they have a urinary tract infection.
- CDC - -Outbreak
- CLSI - -Guides the labs in the proper safety techniques
- What type of specimens cause biological hazards? - -Blood, Urine, and
Body Fluids
- Examples of the types of infections we fear in lab - -HIV, HCV, HBV
- What most happen for a biological hazard to infect a person? - -Direct
contact. Breaking chain of transmission.
- What do we use to warn others of which substances are biohazards? - -Use
the biohazard symbol
- What do the circles of the biohazard symbol represent? - -Top: Source
Bottom Right: Transmission Route
Bottom Left: Host
- The person who has the infection is called... - -Source
- The person who gets the infection due to a breach in the center of
transmission is called... - -Host
- List ways the host can become infected - -Direct contact
