The client who had a synthetic valve replacement a year ago is hospitalized with unstable angina. IV heparin and nitroglycerin infusions were started, but then nitroglycerin was discontinued after the clientÔÇÖs pain resolved. The HCP prescribes to start oral warfarin 5 mg at 1900 hours. Which is the nurseÔÇÖs best action?
Correct answer
A
Rationale
Both heparin and warfarin (Coumadin) are anticoagulants, but their actions are different. Oral warfarin requires 3 to 5 days to reach effective levels. It is usually begun while the client is still on heparin. Warfarin should be given as prescribed for a synthetic valve to prevent thromboembolism.
