Final answer:
The nurse will measure the calf circumference of both legs to assess the immobile patient for deep vein thromboses (DVTs). Elastic stockings and compression stockings are relevant for preventing vein-related issues, and varicose veins share similar risk factors with DVT.
Step-by-step explanation:
When assessing an immobile patient for deep vein thromboses (DVTs), the nurse will take action b. Measure the calf circumference of both legs. This action helps identify potential swelling that may be indicative of a DVT. Additionally, actions like removing elastic stockings or dorsiflexing the foot can be part of the wider DVT assessment and care, but measuring calf circumference is a direct method for assessing potential DVT.
Elastic stockings are frequently used to prevent blood accumulation in the legs and can provide the necessary pressure to enable veins to send blood back to the heart, particularly during long periods of immobility such as long-haul flights. However, they would be removed to properly measure calf circumference if DVT is suspected. Varicose veins can appear as a result of the accumulation of blood and can become painful; they share a common risk factor with DVT as they both can result from poor circulation in the legs.
Procedures like laser surgery or the wearing of compression stockings can alleviate symptoms of varicose veins, which may also help reduce the risk of developing a thrombus or clot in the veins.
