==Question 10==
Which nursing interventions reduce the risk of catheter associated urinary tract infection? '''Select all that apply.'''
# Keeping the drainage bag below the level of the bladder at all times.
# Reviewing the continued need for the catheter daily and removing it as soon as possible.
# Routinely irrigating the catheter with sterile saline every shift.
# Securing the catheter tubing to the patient's thigh to prevent traction.
# Obtaining urine specimens from the sampling port using aseptic technique.
# Disconnecting the tubing from the bag to allow easier patient transfer.

'''Answer:''' 1, 2, 4, and 5.

''Rationale:'' Duration of catheterization is the strongest single risk factor for catheter associated urinary tract infection, so daily review and early removal matter most. Keeping the bag below the bladder prevents backflow of contaminated urine, securing the tubing prevents urethral trauma, and sampling from the port preserves the closed system. Option 3 is incorrect because routine irrigation is not recommended and breaks the closed system. Option 6 is incorrect for the same reason; the closed drainage system must be maintained, and disconnection introduces organisms directly into the system.
