Final answer:
During dialysis, a patient's arm and access site must be uncovered for the procedure to be performed effectively and safely, allowing for proper line connection and monitoring for complications.
Step-by-step explanation:
During dialysis, the patient's arm and access site must be uncovered. Dialysis is a lifesaving medical procedure for patients with kidney failure. The process involves an artificial kidney machine that filters waste products such as urea from the patient's blood. A semi-permeable membrane within the dialyser allows waste and excess water to pass through into the dialysate, while keeping larger blood components, such as red and white blood cells, inside the bloodstream.
To ensure the dialysis treatment is delivered effectively and safely, the patient's arm and access site, where blood enters and leaves their body during treatment, have to be exposed. This allows healthcare providers to monitor the access site for any signs of infection or complications and to ensure the lines are connected properly. Dialysis treatments are typically administered under the direct supervision of a registered nurse, focusing on providing tailored dialysis treatments and maintaining sterile procedures.
