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

Choice A reason: Limiting movement increases venous stasis, raising deep vein thrombosis risk. Mobility, like walking, promotes venous return, preventing clots. This is incorrect, as the nurse should teach interventions like compression devices to enhance circulation, not restrict movement, which worsens thrombosis risk. Choice B reason: Sequential compression devices promote venous return by applying intermittent pressure, reducing stasis and preventing deep vein thrombosis. This is a standard intervention for immobile patients, making it the correct choice to include in teaching for effective DVT prevention among newly licensed nurses. Choice C reason: Massaging lower extremities risks dislodging clots, increasing embolism risk in patients prone to deep vein thrombosis. Compression devices are safer, making this incorrect, as the nurse should avoid teaching interventions that could cause harm instead of preventing thrombosis. Choice D reason: Checking for Homan’s sign (calf pain on dorsiflexion) is a diagnostic, not preventive, measure for deep vein thrombosis and is unreliable. Preventive interventions like compression devices are prioritized, making this incorrect for teaching, as it does not contribute to DVT prevention strategies.
