Final answer:
The nurse should advocate for regular range-of-motion exercises to maintain circulation and reduce the risk of blood clot formation in postoperative patients.
Step-by-step explanation:
To prevent venous stasis and thrombus formation in a postoperative patient, the nurse should promote regular range-of-motion exercises. This activity helps to keep blood circulating, reduces the risk of blood pooling, and thus, diminishes the chance of clot formation. While prolonged bed rest might intuitively seem like a good recovery practice, it actually increases the risk of venous stasis and deep vein thrombosis (DVT). Use of graduated compression stockings can also support circulation, providing external pressure to assist veins in moving blood back toward the heart. Ensuring mobility and the use of appropriate supportive wear are key preventative strategies for postoperative care.
