Final answer:
The correct instruction is that antiembolism stockings should be snug but not too tight, should be worn on both legs, and typically removed before sleep unless medically advised otherwise.
Step-by-step explanation:
The nurse should include in their teachings that the antiembolism stockings should be pulled up snugly but not too tight. This is to ensure proper blood circulation and prevent blood from accumulating in the legs, which can lead to swelling and increased risk for blood clots. It is also essential to apply the stockings to both legs unless otherwise directed by a healthcare provider, and they should be removed before going to bed unless advised otherwise for specific medical reasons. Antiembolism stockings are also known as graduated compression stockings and they are designed to promote venous return during periods of inactivity, such as long-haul flights or postoperative recovery.
