3. The nurse clamps the clear drainage tubing below the self-sealing sampling port for 10 to 30 minutes before collecting a urine specimen from an indwelling urinary catheter to allow accumulation of fresh urine. Before releasing the clamp, the nurse attaches a sterile needle to a 20- to 50-ml syringe (to minimize the number of needle sticks into the port), inserts the needle into the sampling port, withdraws 30–60 ml sterile urine, empties urine into the sterile specimen cup, and seals the sterile cup promptly to prevent contaminating the specimen.
1. Sterile gloves are needed for the perineal preparation for a urine specimen.
2. Inserting a needle into the drainage tubing potentially causes a crack or a leak in the tubing because the tubing is not designed for puncturing.
4. The nurse avoids disconnecting any sterile drain unless necessary; for an indwelling urinary catheter, two other methods of obtaining a sterile specimen exist without disconnecting the tubing.
