Which of the following methods should be used to collect a specimen for urine culture?
  1. Have the client void in a clean container.
  2. Clean the foreskin of the penis of uncircumcised men before specimen collection.
  3. Have the client void into a urinal, and then pour the urine into the specimen container.
  4. Have the client begin the stream of urine in the toilet and catch the urine in a sterile container midstream.
Explanation
Answer: D - Catching urine midstream reduces the amount of contamination by microorganisms at the meat us. Voiding in a urinal doesn’t allow for an uncontaminated specimen because the urinal is not sterile. When cleaning an uncircumcised male, the foreskin should be retracted, and the glans penis should be cleaned to prevent specimen contamination. Voiding in a clean container is done for a random specimen, not a clean-catch specimen for urine culture.
