A patient with suspected urinary tract infection has a urine culture ordered. Which action helps obtain the most accurate clean-catch specimen?
Correct answer: B. Clean the perineum and collect the midstream urine
- A. Collect the first urine passed after waking
- B. Clean the perineum and collect the midstream urine
- C. Insert an indwelling catheter before collecting urine
- D. Collect urine from the drainage bag of a catheter
Explanation
Cleaning the perineum and collecting midstream urine reduces contamination from skin and urethral organisms. The first urine and catheter drainage bag samples are more likely to contain contaminants or colonising bacteria.
