MLT 1203 Clinical Microscopy Exam 2 Review Ch 6-10

Which would compromise the proper care of reagent strips?

• Checking the expiration date

• Storing in a clear container

• Preventing exposure to toxic fumes

• Storing with a desiccant

Reagent strip chemical tests may be inaccurate if the specimen is:

• Mixed before delivery

• Tested immediately after refrigeration

• Tested immediately after it is voided

• Collected by catheter

Quality control must be

• Run at the beginning of each shift

• Run only when a new bottle is opened

• Run once a week

• Run using distilled water

The principle of the reagent strip test for pH is:

• A. A double indicator reaction

• B. The protein error of indicators

• C. The diazo reaction

• D. A Greiss reaction

The normal range of urine pH is:

• 4.5 to 6.0

• 5.0 to 7.0

• 4.5 to 8.0

• 4.5 to 9.0

A urine specimen with a pH of 9.0 indicates that the patient should be:

• Tested further for metabolic or respiratory alkalosis

• Changed to a high meat diet to lower the pH

• Placed on medication to lower the pH

• Asked to collect a new specimen

Which of the following is a cause of prerenal proteinuria?

• Prostatitis

• Multiple myeloma

• Preeclampsia

• Diabetes mellitus

15. The protein section of the reagent strip is most sensitive to:

• Albumin

• Globulin

• Hemoglobin

• Myoglobin

To detect the presence of early renal disease, diabetic patients are tested for:

• Bence Jones protein

• Microalbuminuria

• Orthostatic protein

• Glucose and ketones

A possible cause of postrenal proteinuria is:

• Prostatitis

• Multiple myeloma

• Glomerulonephritis

• Posture
