In an educational plan for clients taking warfarin, which of the following should be emphasized?

When clients are on warfarin, it is crucial to emphasize the avoidance of nonsteroidal anti-inflammatory drugs (NSAIDs). Warfarin is an anticoagulant that works by inhibiting Vitamin K-dependent clotting factors. The use of NSAIDs can significantly increase the risk of gastrointestinal bleeding, which is a serious concern for individuals on anticoagulants. NSAIDs can also affect platelet function, further complicating the anticoagulant effect of warfarin and potentially leading to adverse bleeding events.

By advising clients to avoid NSAIDs, healthcare providers help minimize the risk of complications associated with anticoagulant therapy. Alternative pain relief methods that do not pose the same risks, such as acetaminophen, may be suggested.

In contrast, taking aspirin can also pose risks, particularly as it also affects platelet aggregation and can increase bleeding risks when taken with warfarin. Increasing vitamin K intake counteracts the effect of warfarin, which is not advisable for patients on this medication that relies on maintaining consistent levels of vitamin K. Lastly, consuming green tea may not enhance medication effectiveness; instead, it could interfere with anticoagulation therapy as it contains vitamin K and other compounds that could potentially affect clotting. Thus, the best approach is to
