Deck 20: Physical Characteristics of Urine

Question 1

Bright orange urine is always indicative of elevated bilirubin levels in the specimen.Completion
Complete each statement.

Answer 1

False
Bright orange urine is more often indicative of medication use, such as Pyridium.

Question 2

List one way that the urinometer and refractometer methods for performing specific gravity measurements are different from one another.

Answer 2

The answers may include the volume of urine needed for the testing procedure and the ease of reading the results.

Question 3

How long may a urine specimen be left at room temperature before it must be analyzed, refrigerated, or preserved?

A)Less than 1 hour
B)Less than 3 hours
C)Less than 8 hours
D)Indefinitely

Answer 3

A
If urine is left at room temperature for more than an hour before testing occurs, the bacteria in the specimen may multiply, causing erroneous results. pH changes may also result, as well as chemical changes. Formed elements in the specimen may disintegrate to the point that they are not recognizable when examined microscopically.

Question 4

Excessive urination is called:

A)Polyuria
B)Nocturia
C)Pyuria
D)Oliguria

Question 5

The specific gravity of a substance is the ratio of the weight of the substance as compared to the weight of saline at the same temperature.

Question 6

If hematuria is present, what color may the urine specimen appear?

A)Orange
B)Green
C)Brown
D)Pink or red

Question 7

Insufficient urine volume may affect the quality of the results achieved during a urinalysis.

Question 8

The term used to describe the presence of pus or white cells in the urine is:

A)Hematuria
B)Pyuria
C)Glycosuria
D)Polyuria

Question 9

An ammonia odor may be evident when a urine specimen is at room temperature for ____than 1 hour.Short Answer

Question 10

Urine ____________describes the transparency of the urine specimen.

Question 11

What is one similarity between all the methods presented in this chapter to measure specific gravity?

A)The amount of urine needed for measurement
B)The supplies necessary for the measurement
C)The units of measurement
D)All of the above

Question 12

A meniscus is a curve in the surface of a liquid substance caused by surface tension between molecules.

Question 13

The intensity of the yellow color observed in a urine specimen will vary with the hydration status of the patient.

Question 14

It is more common for amorphous urates to be present in an acidic urine than it is for amorphous phosphates to be present in acidic urine.

Question 15

If a specific gravity measurement is reported as 1.050, this is considered:

A)An abnormal result
B)A normal result
C)An invalid result
D)A very low result

Question 16

Amorphous phosphates are examples of diffuse _____________that cause the urine specimen to appear cloudy.

Question 17

The urine color considered to be normal is:

A)Brown
B)Dark yellow
C)Red
D)Pink

Question 18

A urine specimen that appears bright (fluorescent) yellow may indicate:

A)Ingestion of beets
B)Ingestion of asparagus
C)Ingestion of multivitamins
D)The presence of red blood cells

Question 19

Urinary incontinence may also be known as ____________urination.
