The quizzes about Physical Examination of Urine (26 questions)

The concentration of a normal urine specimen can be estimated by which of the following?

Color

Clarity

Foam

Odor

Correct! Wrong!

The normal yellow color of urine is produced by:

Bilirubin

Hemoglobin

Urobilinogen

Urochrome

Correct! Wrong!

A yellow-brown specimen that produces a yellow foam when shaken can be suspected of containing:

Bilirubin

Carrots

Hemoglobin

Rhubarb

Correct! Wrong!

A urine that turns black after standing may contain:

Homogentisic acid

Melanin

Methemoglobin

All of the above

Correct! Wrong!

Specimens that contain intact RBCs can be visually distinguished from those that contain hemoglobin because:

Hemoglobin produces a much brighter red color

Hemoglobin produces a cloudy, pink specimen

RBCs produce a cloudy specimen

RBCs are quickly converted to hemoglobin

Correct! Wrong!

After eating beets purchased at the local farmers’ market, Mrs. Williams notices that her urine is red, but Mr. William’s urine remains yellow. The Williamses should:

Be concerned because red urine always indicates the presence of blood

Not be concerned because all women produce red urine after eating beets

Be concerned because both of them should have red urine if beets are the cause

Not be concerned because only Mrs. Williams is genetically susceptible to producing red urine from beets

Correct! Wrong!

Specimens from patients receiving treatment for urinary tract infections frequently appear:

Clear and red

Viscous and orange

Dilute and pale yellow

Cloudy and red

Correct! Wrong!

Freshly voided normal urine is usually clear; however, if it is alkaline, a white turbidity may be present due to:

Amorphous phosphates and carbonates

Uroerythrin

WBCs

Yeast

Correct! Wrong!

Microscopic examination of a clear urine that produces a pink precipitate after refrigeration will show:

Amorphous urates

Porphyrins

Red blood cells

Triple phosphate crystals

Correct! Wrong!

Under what conditions will a port-wine urine color be observed in a urine specimen?

The patient has eaten Clorets.

Melanin is present.

Urine contains porphyrins.

The patient has a Pseudomonas infection.

Correct! Wrong!

Which of the following specific gravities would be most likely to correlate with a dark yellow urine?

Correct! Wrong!

Urine specific gravity is equally influenced by the presence of glucose and sodium.

True

False

Correct! Wrong!

In what circumstance might a sediment be slightly warmed prior to microscopic examination?

To hemolyze RBCs

To dissolve amorphous urates

To increase the specific gravity

To correct for temperature in determining the specific gravity

Correct! Wrong!

A urine specific gravity measured by refractometer is 1.029, and the temperataure of the urine is 14C. The specific gravity should be reported as:

1.023

1.027

1.029

1.032

Correct! Wrong!

Refractive index compares:

Light velocity in solutions with light velocity in solids

Light velocity in air with light velocity in solutions

Light scattering by air with light scattering by solutions

Light scattering by particles in solution

Correct! Wrong!

Refractometers are calibrated using:

Distilled water and protein

Distilled water and blood

Distilled water and sodium chloride

Distilled water and urea

Correct! Wrong!

A correlation exists between a specific gravity of 1.050 and a:

2 glucose

2 protein

First morning specimen

Radiographic dye infusion

Correct! Wrong!

An alkaline urine turns black upon standing, develops a cloudy white precipitate, and has a specific gravity of 1.012. The major concern about this specimen would be:

Color

Turbidity

Specific gravity

All of the above

Correct! Wrong!

The reading of distilled water by the refractometer is 1.003. You should:

Subtract 1.003 from each specimen reading

Add 1.003 to each specimen reading

Use a new refractometer

Adjust the set screw

Correct! Wrong!

A urine specimen with a specific gravity of 1.008 has been diluted 1:5. The actual specific gravity is:

1.008

1.040

1.055

5.040

Correct! Wrong!

The method for determining a urine specific gravity that is based on the principle that the frequency of a sound wave entering a solution changes in proportion to the density of the solution is:

Colorimetric

Harmonic oscillation densitometry

Refractometry

Urinometry

Correct! Wrong!

A specimen with a specific gravity of 1.005 would be considered:

Isosthenuric

Hyposthenuric

Hypersthenuric

Not urine

Correct! Wrong!

Specific gravity is of more diagnostic value than osmolarity in evaluating renal concentration ability.

True

Correct! Wrong!

A strong odor of ammonia in a urine specimen could indicate:

Ketones

Normal

Phenylketonuria

Urinary tract infection

Correct! Wrong!

The microscopic of a cloudy amber urine is reported as rare WBCs and epithelial cells. What does this suggest?

Urinary tract infection

Dilute random specimen

Precipitated amorphous urates

Possible mix-up of specimen and sediment

Correct! Wrong!

A specimen with a strong ammonia odor and a heavy white precipitate when it arrives in the laboratory may require:

Collection of a fresh specimen

Centrifugation

Dilution for specific gravity

Testing under a hood

Correct! Wrong!
