Which action should a nurse take to prevent infection in a client with an indwelling urinary catheter?

The best action a nurse can take to prevent infection in a client with an indwelling urinary catheter is to check the catheter tubing for kinks or twisting. Proper positioning of the catheter and its tubing is crucial for maintaining the flow of urine and preventing any backflow, which can lead to bacterial growth and increased risk of infection. Ensuring that the tubing is not obstructed helps to maintain an unobstructed drainage pathway, which is vital when preventing urinary tract infections (UTIs).

When the tubing is kinked or twisted, it can cause urine to accumulate and potentially create a breeding ground for bacteria. By regularly assessing the catheter and tubing for any kinks, the nurse can intervene promptly to ensure the drainage system is functioning properly.

Other options, while they may seem beneficial, do not directly address infection prevention as effectively. For instance, replacing the catheter every 3 days can actually increase the risk of introducing new pathogens, as any catheter insertion carries the risk of introducing bacteria. Irrigating the catheter can also increase the risk of infection if not done under sterile conditions, and while cleaning the perineal area is important, using an antiseptic solution daily is not typically necessary and can disrupt the natural flora, potentially leading to infections rather than preventing
