Final answer:
The nurse should notify the provider if the catheter tubing has multiple red clots, as this could indicate bleeding or clot formation.
Step-by-step explanation:
The nurse should notify the provider for the assessment finding of multiple red clots in the catheter tubing. This could indicate bleeding or clot formation, which may be a sign of a complication following the transurethral resection of the prostate (TURP) surgery. The nurse should closely monitor the client for any signs of excessive bleeding, such as decreased urine output or hypotension.
