A quantitative assessment of the urobilinogen level is performed on which type of urine specimen?

A technologist performing a microscopic examination on a urine sediment is trying to determine whether he is looking at a large white cell or a renal tubular cell.  He reports 2-4 renal tubular cells based on which criterion?

The presence of which type of cell indicates vaginal contamination in a random urine specimen or an improperly collected midstream clean catch urine specimen?

Whenever the reagent pad shows a negative result for blood and the microscopic examination reveals RBCs, the technologist should suspect the presence of:

The stain most commonly used to enhance visualization of urine sediment is:

The urinalysis of a 70-year-old male who takes an alkaline medication reveals 3+ protein on the reagent test strip and a pH of 9.0.  The technologist should:

A 45-year-old patient who received a kidney transplant 2 months ago presents to the ED with a temperature of 100F, chills, aches, headache, dizziness, oliguria, and a weight gain of 6 pounds since yesterday.  The technologist notes that the predominant WBC in the microscopic examination is:

Postural (orthostatic) proteinuria requires:

The technologist records these results on a urinalysis and Clinitest: glucose 4+ on reagent strip and negative for Clinitest.  The most likely explanation is:

A technologist dips a reagent strip into a urine specimen and then reads it manually, following the manufacturer’s specifications.  After performing the microscopic examination, he notes that the dipstick color on the edge of the reaction pad for ketones is darker than when he had first read it.  The technologist:
