A client who was discharged 3 days ago after an exploratory laparoscopic biopsy is admitted to the hospital with a warm, tender, reddened, and swollen left lower leg. The nurse is preparing to initiate heparin therapy. Which additional intervention should the nurse include in this client's plan of care?

A. Maintain the client on bedrest: The client’s symptoms are consistent with deep vein thrombosis (DVT). Bedrest with limited movement prevents dislodgment of the clot, which could otherwise travel to the lungs and cause a pulmonary embolism. This is the safest initial intervention while anticoagulation is being started. B. Administer the client's routine daily aspirin: Aspirin has antiplatelet effects but is not the treatment of choice for acute DVT. Starting aspirin with heparin therapy is not recommended, as it increases the risk of bleeding without additional therapeutic benefit. C. Encourage a diet high in iron and ascorbic acid: While iron and vitamin C support red blood cell production, this dietary intervention does not address the acute management of a thrombus. It may be useful in anemia prevention but is not a priority here. D. Encourage the client to dangle the legs frequently: Dangling the legs promotes venous stasis and may worsen the clot or increase the risk of embolization. Clients with DVT should avoid activities that increase venous pooling until cleared by the healthcare provider.
