What should a client taking warfarin sodium indicate as a need for further teaching?

The client’s statement about taking Ecotrin (enteric-coated aspirin) for headaches indicates a need for further teaching because using aspirin while on warfarin can increase the risk of bleeding. Aspirin has anticoagulant properties and can potentiate the effects of warfarin. This combination can lead to dangerous bleeding complications, which are particularly concerning for patients who are already on anticoagulant therapy.

In contrast, the other statements reflect safe practices and an understanding of the necessary precautions while managing warfarin therapy. Taking medication consistently at the same time each day helps maintain stable blood levels of the anticoagulant. Avoiding alcohol is important, as it can affect how warfarin works and increase the risk of bleeding. Wearing a Medic-Alert bracelet is also a wise decision, as it informs healthcare providers of the client's anticoagulant therapy in case of an emergency, which is crucial for safe care in unexpected situations.
