HARR_6.5 Urinalysis & Body Fluids Problem Solving 100% Accurate!

HARR_6.5 Urinalysis & Body Fluids Problem S Given the following dry reagent strip urinalysis results, select the most appropriate course of action: pH = 8.0 Protein = 1+ Glucose = Neg Blood = Neg Ketone = Neg Nitrite = Neg Bilirubin = Neg A. Report the results, assuming acceptable quality control B. Check pH with a pH meter before reporting C. Perform a turbidimetric protein test, instead of the dipstick protein test, and report D. Request a new specimen - ANSWERSC Highly buffered alkaline urine may cause a false-positive result on the dry reagent strip protein test by titrating the acid buffer on the reagent pad. Protein should be measured by an alternate method that is not subject to positive interference by highly buffered alkaline urine. Given the following urinalysis results, select the most appropriate course of action: pH = 8.0 Protein = Trace Glucose = Neg Ketone = Small Blood = Neg Nitrite = Neg Microscopic findings: RBCS = 0-2/HPF WBCS = 20-50/HPF Bacteria = Large Crystals = Small, CaCO, A. Call for a new specimen because urine was contaminațed in vitro B. Recheck pH because CACO, does not occur at alkaline pH C. No indication of error is present; results indicate a UTI D. Report all results except bacteria because the nitrite test was negative - ANSWERSC A positive nitrite result requires infection with a nitrate-reducing organism, dietary nitrate, and incubation of urine in the bladder. The test is positive in about 70% of UTI cases. Alkaline pH, bacteriuria, and leukocytes point to UTI. SITUATION: A 6-mL pediatric urine sample is processed for routine urinalysis in the usual manner. The sediment is prepared by centrifuging all of the urine remaining after performing the biochemical tests. The following results are obtained: SG = 1.015 Blood = Large Leukocytes = Moderate Protein = 2+ RBCS: 5-10/HPF WBCS: 5-10/HPF Select the most appropriate course of action. A. Report these results; blood and protein correlate with microscopic results B. Report biochemical results only; request a new sample for the microscopic examination C. Request a new sample and report as quantity not sufficient (QNS) D. Recentrifuge the supernatant and repeat the microscopic examination - ANSWERSB This discrepancy between the blood reaction and RBC count resulted from spinning less than 12 mL of urine. When volume is below 12 ml, the sample should be diluted with saline to 12 ml before concentrating. Results are multiplied by the dilution (12 mL/mL urine) to give the correct range. olving 100% Accurate!
