A strategy for preventing thromboembolism in patients at risk who cannot take anticoagulants is:
a. administration of two aspirin tablets every 4 hours.
b. infusion of thrombolytics.
c. insertion of a vena cava filter.
d. subcutaneous heparin administration every 12 hours.
C
A filter may be inserted as a prevention measure in patients who are at high risk for thromboembolism. Aspirin is not a preventive therapy. Thrombolytics are given to treat, not prevent, pulmonary embolism. Heparin is administered as a prophylaxis in acute care settings. Coumadin is given for long-term prevention in patients at high risk for VTE.
