Final answer:
The nurse must take immediate action when a patient who has undergone TURP has bright red drainage with multiple blood clots, as it indicates active bleeding, potentially requiring urgent medical intervention.
Step-by-step explanation:
The assessment finding that requires immediate action by the nurse for a client who has undergone a transurethral resection of the prostate (TURP) is having bright red drainage with multiple blood clots. This finding is indicative of active bleeding and could signal a postoperative complication that necessitates urgent medical intervention. Management may include assessing the patient's vital signs, notifying the physician, and preparing to administer treatments which might include fluids, blood products, or further surgical intervention to control the bleeding.
Having the urge to void continuously while the catheter is in place and experiencing urinary frequency after catheter removal are common symptoms following a TURP procedure and typically do not warrant immediate action. Passing small blood clots after catheter removal can be expected, but should be monitored for changes in volume and size of the clots.
