The nurse is caring for a patient with an indwelling urinary catheter. The nurse is aware that what nursing action helps prevent infection in a patient with an indwelling catheter?
A) Vigorously clean the meatus area daily.
B) Apply powder to the perineal area twice daily.
C) Empty the drainage bag at least every 8 hours.
D) Irrigate the catheter every 8 hours with normal saline.
Ans: C
Feedback: Vigorous cleaning of the meatus while the catheter is in place is discouraged, because the cleaning action can move the catheter, increasing the risk of infection. The spout (or drainage port) of any urinary drainage bag can become contaminated when opened to drain the bag. Bacteria enter the urinary drainage bag, multiply rapidly, and then migrate to the drainage tubing, catheter, and bladder. By keeping the drainage bag lower than the patient's bladder and not allowing urine to flow back into the bladder, this risk is reduced. Irrigation of the catheter opens the closed system, increasing the likelihood of infection.
