A nurse is reinforcing teaching about the prevention of deep vein thrombosis (DVT) with a group of newly licensed nurses. Which of the following interventions should the nurse include in the teaching?

A. Massaging the lower extremities can dislodge a clot if present, leading to embolization, and is contraindicated. B. Limiting movement of the lower extremities increases venous stasis and the risk for clot formation; instead, early ambulation and movement are encouraged. C. Sequential compression devices promote venous return and are an evidence-based intervention for the prevention of DVT. D. The Homans' sign is no longer considered a reliable or safe diagnostic tool for DVT; it is not a preventive intervention.
