A nurse is reconciling a client's medications and finds the client is taking warfarin and was just prescribed aspirin by a different provider. What is the priority action?

MEDICATION RECONCILIATION — CATCHING INTERACTIONS: Warfarin (anticoagulant) + aspirin (antiplatelet) = significantly increased bleeding risk; this combination requires provider awareness and may be intentional (some cardiac conditions) or an oversight from separate prescribers.

Priority: Recognize the interaction; notify the provider to confirm intent before administering; do not simply give both without clarification.

Medication reconciliation: Comparing the client's current medications across transitions of care (admission, transfer, discharge) to identify and resolve discrepancies — duplications, omissions, interactions, dosing errors; a National Patient Safety Goal; HIGH-RISK INTERACTIONS to know: anticoagulant + antiplatelet (bleeding); ACE inhibitor + potassium (hyperkalemia); multiple QT-prolonging drugs (dysrhythmia); MAOIs + many drugs/foods.

Involve: pharmacist for complex reconciliation.

Safety culture: Catching these is exactly why reconciliation exists; LPN role: participate in reconciliation, recognize potential interactions, notify the provider, advocate for client safety.
