A triple-lumen indwelling urinary catheter is inserted for continuous bladder irrigation following a transurethral resection of the prostate. In addition to balloon inflation, the nurse is aware that the functions of the three lumens include:
A. Continuous inflow and outflow of irrigation solution.
B. Intermittent inflow and continuous outflow of irrigation solution.
C. Continuous inflow and intermittent outflow of irrigation solution.
D. Intermittent flow of irrigation solution and prevention of hemorrhage.
Correct Answer: A. Continuous inflow and outflow of irrigation solution.
When preparing for continuous bladder irrigation, a triple-lumen indwelling urinary catheter is inserted. The three lumens provide for balloon inflation and continuous inflow and outflow of irrigation solution.
Option B: A three-way or triple lumen catheter has three separate openings. One lumen inflates the balloon holding the catheter in place. The second lumen allows for the outflow of urine and the outflow of drainage solution. The third lumen allows for the inflow of irrigating solution (antibacterial rinse) into the bladder.
Option C: Check the inflow and outflow lines periodically for kinks, to make sure the solution is running freely. Measure the outflow volume correctly. Outflow volume should equal or, allowing for urine production, slightly surpass inflow volume. If inflow volume exceeds the outflow volume, suspect bladder rupture or renal damage, and notify the professional nurse immediately.
Option D: Instead of the traditional one-way (or single lumen) catheter for a straight cath, or a two-way for an indwelling, this one has three lumens. This is because the nurse is not only emptying the bladder through one but also infusing normal saline (NS) solution into another. The third lumen is used to inflate a balloon, once the catheter is inside the bladder, to keep it in place.
