The nurse is planning care for a client recovering from orthopedic surgery. Interventions should be included to address which contributing factor to deep vein thrombosis development?

A. Smoking: Although smoking is a risk factor for cardiovascular diseases and can contribute to thrombosis, it is not the most immediate factor in the context of post-surgical immobility. B. Hypertension: While hypertension is a significant cardiovascular risk factor, it is less directly related to deep vein thrombosis compared to immobility. C. Obesity: Obesity can increase the risk of DVT, but immobility, especially after surgery, is a more direct and immediate contributing factor. D. Immobility: Immobility is a critical factor in the development of deep vein thrombosis, particularly in postoperative clients who may be bedridden or have limited mobility.
