Final answer:
The nurse should evaluate the patient for signs and symptoms of infection if a temporary percutaneous catheter has been in place for acute kidney injury treatment for 5 days. Option b is correct.
Step-by-step explanation:
If a patient has a temporary percutaneous catheter in place for the treatment of acute kidney injury, and the catheter has been in place for 5 days, the appropriate nursing action would be to evaluate the patient for signs and symptoms of infection. This is essential because venous catheters can be common sites for bloodstream infections.
The World Health Organization notes that there are significant numbers of catheter-related bloodstream infections each year resulting in substantial mortality. It would not be necessary to prepare for a routine dialysis catheter change as this is usually not performed on such a short time scale unless there are specific indications. Teaching the patient that the catheter is for long-term use is incorrect as the patient's catheter is temporary. Lastly, using one of the lumens for fluid administration may not be appropriate if all lumens are dedicated to dialysis treatment.
