- Urine from patients with diabetes mellitus has: (increased or decreased)
volume and (increased or decreased) specific gravity - -increased volume,
increased specific gravity
, - A first morning urine is the specimen of choice for routine urinalysis
because - -it is more concentrated, resulting in better detection of
abnormalities
- Total renal blood flow is approximately - -1200 ml/min
- The normal kidney performs all of the following EXCEPT:
(a) regulation of fluid and electrolyte balance
(b) regulation of acid-base balance
(c) plays a role in hormonal function
(d) removes excess protein from the blood - -(d) removes excess protein
from the blood
- The glomerulate filtrate is described as
(a) a protein filtrate of plasma
(b) a glucose and protein containing filtrate of plasma
(c) a plasma filtrate without glucose and protein

filtrate of plasma that does not contain protein
- Glucose starts to spill in the urine when the renal threshold reaches: - -
160-180 mg/dL
- The normal yellow color of urine is produced by - -urochrome
- Freshly voided urine is normally clear; however, if it is alkaline, a white
turbidity may be present due to: - -Amorphous phosphates
- Refractive index compares
(a) light velocity in solution with light velocity in solids
(b) light velocity in air with light velocity in solutions
(c) light scattering by air with light scattering y solutions
(d) light scattering by particles in solution - -(b) light velocity in air with light
velocity in solutions
- An alkaline urine turns black upon standing, develops a cloudy white
precipitate, and has a specific gravity of 1.022. THe major concern about this
specimen would be
(a) color
(b) turbidity
(c) specific gravity
(d) all of the above - -(a) color

office. The doc instructs the pt to go home and rest and to collect a
