Final answer:
The nurse should measure the client's legs with a tape measure to determine the correct size for the antiembolitic stockings. Massaging the legs before applying the stockings is not recommended. The stockings should be left on continuously, only removed when necessary.
Step-by-step explanation:
The nurse should measure the client's legs with a tape measure to determine the correct size for the antiembolitic stockings. This is important because the stockings need to fit properly in order to provide the necessary pressure to prevent blood accumulation and aid in blood flow. Massaging the legs before applying the stockings is not recommended as it can dislodge any existing blood clots. The stockings should also be left on continuously, only removed when necessary for bathing or other reasons.
