Final answer:
The appropriate intervention for infective endocarditis involves hospitalization for IV antibiotic treatment, not just oral antibiotics, complete bed rest, or anticoagulation therapy.
Step-by-step explanation:
The appropriate treatment intervention for a patient with infective endocarditis is hospitalization for initial intravenous (IV) antibiotics, often requiring a central line for administration. Although oral antibiotics like penicillin have their place in treatment, especially for long-term prophylaxis, they are not the primary intervention for acute infective endocarditis. Bed rest may be recommended during the acute phase of illness, but complete bedrest for the duration of treatment is not typically prescribed. Long-term anticoagulation therapy with heparin is not a standard treatment for infective endocarditis unless specific conditions warrant it, such as the presence of embolic complications.
