Final answer:
The most important information to include in the nurse's discharge teaching for a client prescribed warfarin is to report nose or gum bleeding.
Step-by-step explanation:
When discharging a client with a prescription for warfarin, there are several important pieces of information that should be included in the nurse's discharge teaching. However, the most important information to include is to report nose or gum bleeding. This is because warfarin is an anticoagulant medication, and nose or gum bleeding may indicate that the client's blood is not clotting properly.
Other important information that should be included in the discharge teaching includes using a soft toothbrush to prevent gum bleeding, avoiding eating leafy green vegetables because they contain high levels of vitamin K which can interfere with the effectiveness of warfarin, and being cautious about taking certain medications, such as acetaminophen, without consulting a healthcare provider.
