A client is receiving a postoperative continuous bladder irrigation via a three-way indwelling catheter for a transurethral resection of the prostate (TURP). Twelve hours after the surgery, the practical nurse (PN) is monitoring the urine in the catheter's bedside drainage unit and observes that the drainage is a thick red fluid with clots. What action should the PN implement?

A. Checking for kinks in the drainage tubing might be a part of troubleshooting, but the observed clots and thick red fluid require immediate attention, so informing the charge nurse is the priority. B. Delaying assessment for another hour could potentially exacerbate the issue if there's a problem with the irrigation or if the client's condition worsens. C. Reporting the finding to the charge nurse is crucial as it indicates potential complications such as bleeding or clot formation that need immediate intervention. D. Immediately stopping the irrigation solution without proper assessment and guidance could lead to complications and isn't the initial action warranted in this situation.
