Final answer:
Anti-Embolus hose should be applied when the patient is lying down with legs elevated to improve blood circulation and prevent DVT. The stockings must be fitted smoothly to avoid uneven pressure and restriction of blood flow.
Step-by-step explanation:
When applying Anti-Embolus hose (also known as graduated compression stockings), it is recommended that the patient is in a lying position with legs slightly elevated to reduce venous pressure and facilitate proper circulation. This position helps in the prevention of deep vein thrombosis (DVT) by promoting blood flow. The stockings should be applied smoothly and without wrinkles to ensure even compression and avoid restricting circulation.
