Strasinger Chapter 5 "Chemical examination
of urine" UPDATED ACTUAL Questions
and CORRECT Answers
Reagent strips - CORRECT ANSWER - these examine = pH, protein, glucose, ketones,
blood, bilirubin, urobilinogen, nitrite, leukocytes, specific gravity
Reagent strip bottles - CORRECT ANSWER - store these at room temperature
QC is done with positive and negative controls every - CORRECT ANSWER - 24 hrs
Confirmatory testing - CORRECT ANSWER - using different methods to detect the same
substances
pH - CORRECT ANSWER - kidneys and lungs regulate this acid base in the body.
Clinical significance of pH - CORRECT ANSWER - aids in determining disorders of the
metabolic or respiratory origin.
Urinary pH - CORRECT ANSWER - may indicate a disorder resulting from the kidneys
inability to secrete or to reabsorb acid or base.
Urine pH control - CORRECT ANSWER - mainly the diet
pH # - CORRECT ANSWER - fresh urine does not reach above 8.5. This would indicate
improper storage or abnormal conditions. Request new urine sample
Reagent strip reaction - CORRECT ANSWER - methyl red --> bromthymol blue
, Protein in urine - CORRECT ANSWER - the most indicative of renal disease
major serum found in normal urine - CORRECT ANSWER - albumin
Tamm-horsfall protein - CORRECT ANSWER - uromodulin
Uromodulin is produced - CORRECT ANSWER - in the distal convoluted tubule
Clinical significance of protein - CORRECT ANSWER - can help diagnose, prerenal,
renal, and post renal
Prerenal proteinuria - CORRECT ANSWER - caused by conditions affecting the plasma
prior to reaching the kidneys
Bence Jones protein - CORRECT ANSWER - possible multiple myeloma
Renal proteinuria - CORRECT ANSWER - renal disease resulting in glomerular or tubular
damage
glomerular proteinuria - CORRECT ANSWER - resulting damage lets more proteins pass
and eventually RBC's and WBC's
Proteinuria can be associated with... - CORRECT ANSWER - extreme exercise, and also
cause pre-eclampsia during pregnancy
Micro albuminuria - CORRECT ANSWER - can show in those with diabetes mellitus 1&2
orthostatic proteinuria - CORRECT ANSWER - evident in those that are vertical but
disappears when horizontal. Good for morning urine collection
