Your patient receives peritoneal dialysis (PD) at home. You know that which of the following occurs during the inflow or fill phase?

A. A prescribed volume of dialysate solution is infused through a catheter into the peritoneal space and inflow clamp is closed is correct because the inflow (fill) phase of PD involves introducing a prescribed amount of dialysis solution into the peritoneal cavity through a tenckhoff catheter. Once the solution has entered, the inflow clamp is closed, allowing the patient to proceed to the dwell phase. B. Waste products and fluids are drained from the peritoneal space into the drainage bag is incorrect because this describes the drain phase, which occurs after the dwell phase. During drainage, toxins, excess electrolytes, and fluid move from the blood into the dialysate and are removed from the peritoneal cavity. C. Diffusion and osmosis are occurring between patient's blood and peritoneal cavity is incorrect because this process occurs primarily during the dwell (equilibration) phase, not the inflow phase. During dwell, waste products and excess fluid move from the bloodstream into the dialysate via osmosis and diffusion. D. Access to AV graft is obtained with 2 large bore needles is incorrect because this describes hemodialysis, not peritoneal dialysis. PD uses a catheter in the peritoneal cavity rather than vascular access.
