Urinalysis and Body Fluids Exam With
Verified Questions and Answers
A patient with uncontrolled diabetes mellitus will most likely have - answer✔✔pale urine with
high specific gravity
-High specific gravity is due to the glucose in the urine. People w/diabetes have polyuria, so the
volume of urine dilutes the urochrome (color), making it pale.

To prep a solution appropriate for quality control of the refractometer, the laboratorian should
use - answer✔✔Sodium Chloride w/Specific Gravity of 1.022
-b/c it is the easiest control (6.5% NaCl)
A urine's specific gravity is directly proportional to its - answer✔✔Dissolved Solids
-dissolved solids (salt, sugar, urea, etc.) contribute to specific gravity
