Specimen collection

Question 1

aseptic technique

Answer 1

method use to prevent contamination from microorganisms

-prevent/risks that you’ll experience with infection

Question 2

aerobic culture

Answer 2

living only in presence of oxygen

Question 3

anaerobic culture

Answer 3

living only in absence of oxygen

Question 4

culture & sensitivity

Answer 4

lab cultivation of micro-organisms in a body fluid or substance placed in a special growth medium, followed by ID of antibiotic agents that can kill pathenogenic microorganisms grown

Question 5

clean-voided (midstream) urine specimen (clean catch)

Answer 5

sample of urine collected after beginning to urinate into the toilet, stopping the stream of urine, then urinating into a sterile collection cup

Question 6

double-voided urine specimen

Answer 6

this refers to a urine specimen which is collected after first emptying the bladder and then waiting until another specimen can be collected. These double-voided urine specimens are more accurate for purposes of glucose testing (urinalysis). If you test a urine specimen that has been held in the bladder for an extended period of time, it will not accurately reflect the glucose content in the bloodstream. A freshly, double voided specimen is preferred.

Question 7

urine culture

Answer 7

A urine culture is a test to find germs (such as bacteria) in the urine that can cause an infection. Urine in the bladder is normally sterile. This means it does not contain any bacteria or other organisms (such as fungi). But bacteria can enter the urethra and cause a urinary tract infection (UTI).

Question 8

urine reagent test strip

Answer 8

a chemically treated band that, when dipped into a urine sample and color changes are observed, yields information about pH, specific gravity, leukocytes or leukocyte esterase, blood, ketones, bilirubin or urobilinogen, and glucose (varying with the type of test strip used)

Question 9

timed urine specimen

Answer 9

At the beginning of the time period, empty your bladder and discard that urine. Note the time. Collect all urine voided for the specified period of time in the container provided. At the end of the time period, empty your bladder and ADD this urine to the container.

Question 10

dysuria

Answer 10

painful and difficult urination

Question 11

hematuria

Answer 11

blood in urine

Question 12

urgency

Answer 12

immediate and strong “desire to void” that is not easily deferred

Question 13

Wound culture

Answer 13

A wound culture is a diagnostic laboratory test in which microorganisms—such as bacteria or fungi from an infected wound, are grown in the laboratory on nutrient-enriched substance called media—then identified.

Question 14

point of care testing

Answer 14

at or near the site or time of patient care, as in point-of-care testing

Question 15

lancet

Answer 15

a sharp, pointed device used to make small incisions or punctures in the skin

Question 16

blood glucose monitoring (glucometer)

Answer 16

a device used to determine the approximate concentration of glucose in the blood

Question 17

guaiac test

Answer 17

a tree resin used as a reagent in the detection of occult (hidden) blood

Question 18

occult blood (stool or gastric)

Answer 18

blood present in small amounts as to be detectable only by specific diagnostic tests

Question 19

melena

Answer 19

black, tarry feces created by the action of intestinal secretions on blood

Question 20

gastric ph

Answer 20

The pH of gastric acid is 1.5 to 3.5 in the human stomach lumen, the acidity being maintained by the proton pump H+/K+ ATPase.

Question 21

sputum specimen

Answer 21

Testing sputum helps clinicians diagnose things like pneumonia, bronchitis, and TB and determine the cause of things like a lung abscess. For the sample to be useful, though, it must come from deep within the lungs. In addition, the specimen must be of sufficient quantity

Question 22

throat culture

Answer 22

diagnostic test that evaluates presence of bacterial or fungal infection in the throat

Question 23

gum specimen

Answer 23

collect by lightly scraping the inside of the patient’s cheek with a sterile swab

Question 24

false-negative or false -positive results

Answer 24

storage conditions , inadequate specimen collection, and some patient factors can lead to false positive or negative results
