The nurse needs to obtain a sterile urine specimen for culture and sensitivity (C&S) from a patient who has an indwelling catheter.The catheter was placed the night before.What must the nurse do to obtain the specimen?

A) Obtain the urine from the drainage bag.
B) Clamp the drainage tubing for 10 to 15 minutes.
C) Draw urine using a 20-mL syringe.
D) Insert the needle into the silicone catheter.

Clamp the drainage tubing with a clamp or rubber band for 30 minutes to permit collection of fresh,sterile urine in the catheter tubing rather than draining into the bag.Do not collect a urine specimen for culture tests from a urine drainage bag unless it is the first urine to drain into a new sterile bag.Draw urine into a 3-mL syringe (for culture),or draw urine into a 20-mL syringe (for routine urinalysis).Proper volume is needed to perform the test.Do not puncture Silastic,silicone,or plastic catheters.These are not self-sealing.
