The nurse knows that which indwelling catheter procedure places the patient at greatest risk for acquiring a urinary tract infection?
a. Emptying the drainage bag every 8 hours or when half full
b. Kinking the catheter tubing to obtain a urine specimen
c. Placing the drainage bag on the side rail of the patient's bed
d. Failing to secure the catheter tubing to the patient's thigh
ANS: C
Placing the drainage bag on the side rail of the bed could allow the bag to be raised above the level of the bladder and urine to flow back into the bladder. The urine in the drainage bag is a medium for bacteria; allowing it to reenter the bladder can cause infection. The drainage bag should be emptied and output recorded every 8 hours or when needed. Urine specimens are obtained by temporarily kinking the tubing; a prolonged kink could lead to bladder distention. Failure to secure the catheter to the patient's thigh places the patient at risk for tissue injury from catheter dislodgment.
