Final answer:
The surgical scrub nurse should prevent DVT by actively flexing leg muscles, changing positions to maintain blood flow, using compression stockings, and taking breaks to walk and stretch.
Step-by-step explanation:
The surgical scrub nurse should take certain actions to prevent personally developing a Deep Vein Thrombosis (DVT). Among the advisable actions, flexing the leg muscles and changing leg positions frequently is a preventive measure against DVT. This activity helps maintain blood flow in the legs and reduces the risk of clot formation. The use of graduated compression stockings is also recommended to exert pressure on the lower legs, which aids in blood flow back to the heart. Additionally, taking breaks during prolonged surgeries to walk and stretch can further decrease the risk of DVT.
