Final answer:
In hemodialysis, step 1 involves preparing the patient for dialysis by placing a dialysis access, either an arteriovenous fistula or graft. The access allows blood to be removed from the patient's body and returned after filtration.
Step-by-step explanation:
To initiate hemodialysis, several steps need to be taken. Step 1 involves preparing the patient for dialysis by placing a dialysis access, either an arteriovenous fistula or graft. An arteriovenous fistula connects an artery and a vein directly, while a graft uses a synthetic tube to connect the artery and vein. This access allows blood to be removed from the patient's body and returned after filtration. Prior to starting hemodialysis, the access site is prepared and assessed for appropriate blood flow.
