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

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

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

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:

A technologist is logging urine color and clarity for specimens being run on the Clinitek analyzer.  He notes an abnormal orange color in one specimen and notices that all the test pads for that specimen were reported as positive.  Upon microscopic examination, the technologist reports a negative result for all cellular and crystal elements.  The next course of action should be:

A 32-year-old woman presents to the ED with fever, oliguria, hematuria, and a rash.  She reports that she has a sinus infection and is currently taking penicillin.  The physician suspects that the patient has acute interstitial nephritis (AIN); she therefore orders which tests to be performed on the patient’s urine specimen?
