Final answer:
The nurse should report the finding of cola-colored urine to the healthcare provider.
Step-by-step explanation:
The nurse should report the finding of cola-colored urine to the healthcare provider.
Warfarin is an anticoagulant drug used to prevent blood clotting in patients with mechanical heart valves. Cola-colored urine can be a sign of hematuria, which is the presence of blood in the urine.
This finding may indicate a potential complication of warfarin therapy, such as bleeding or hemorrhage, and should be reported to the healthcare provider for further evaluation and management.
