During the collection of a midstream urine specimen, what is done after cleaning the perineal area and starting to void?

  1. Continue voiding into the toilet

  2. Void directly into the specimen container

  3. Stop voiding halfway

  4. Discard the first part of the voiding

The correct answer is: Continue voiding into the toilet

After cleaning the perineal area and starting to void, the individual should continue voiding into the toilet. This allows for a midstream urine specimen to be collected, which ensures that the sample is free from any contaminants from the urethra. Voiding directly into the specimen container (choice B) may result in a contaminated sample. Stopping voiding halfway (choice C) may also result in a contaminated sample as the first part of the urine stream may contain bacteria from the urethra. Discarding the first part of the voiding (choice D) is not necessary and may result in an inadequate sample for testing. Therefore, choice A is the correct option as it ensures a clean and accurate midstream urine specimen is collected.
