What is the normal pH range for urine?
Answer: 4.5 to 8.0
Normal urine pH ranges from 4.5 to 8.0, with an average of approximately 6.0. Urine pH reflects the kidneys' role in maintaining the body's acid-base balance.
Which urine specimen collection method is used to obtain a sterile urine sample for culture and sensitivity testing?
Answer: Clean-catch midstream specimen
A clean-catch midstream specimen is the preferred non-invasive method for obtaining a urine sample suitable for culture and sensitivity testing, minimizing contamination from skin flora.
On a urine dipstick test, a positive result for nitrites most likely indicates:
Answer: Bacterial infection in the urinary tract
A positive nitrite test on a urine dipstick indicates the presence of gram-negative bacteria that convert urinary nitrates to nitrites, suggesting a urinary tract infection (UTI).
What does specific gravity measure in a urine sample?
Answer: The concentration of solutes compared to pure water
Specific gravity measures the density and concentration of dissolved substances (solutes) in urine relative to pure water, reflecting the kidneys' ability to concentrate or dilute urine.
Which of the following is an abnormal finding when examining urine under a microscope?
Answer: More than 10 bacteria per high power field
More than 10 bacteria per high power field in urine is an abnormal finding suggesting bacteriuria, which may indicate a urinary tract infection.
What is glucosuria and what does it typically indicate?
Answer: The presence of glucose in the urine, typically indicating elevated blood glucose levels
Glucosuria (also spelled glycosuria) is the presence of glucose in the urine, which typically occurs when blood glucose levels exceed the renal threshold of approximately 180 mg/dL.
