In Modified PET, what are the daytime solution strength and the UF status?

• A. 2.5% Overnight & 4.25% Solution During the Day; UF Present
• B. 2.5% Overnight & 4.25% Solution During the Day; Patient Does Not Have UF
• C. 4.25% Overnight & 2.5% Daytime Solution; UF Status Not Specified
• D. 2.5% Overnight Only; Daytime 4.25% Not Used

Answer: (B)

Modified PET uses two dwell conditions to assess how the peritoneal membrane handles fluid removal and solute transport. The daytime portion uses a higher concentration of dextrose (4.25%) to create a strong osmotic gradient that drives ultrafiltration during the day. The UF status is simply whether ultrafiltration actually occurs during that daytime dwell. In this scenario, the daytime strength is 4.25%, and the observation is that ultrafiltration does not occur during the daytime dwell. This is why the correct description is the daytime solution at 4.25% with no UF during that daytime dwell.
