Which statement about machine temperature checks is accurate?

• A. Temperature is checked only if readings change
• B. Temperature is never checked
• C. Temperature is checked only after treatment ends
• D. Temperature is checked when conductivity and temperature are stable; document prior to tx

Answer: (D)

Temperature checks are part of the pre-treatment verification and should be done when the readings have stabilized. Waiting for both conductivity and temperature to be stable ensures the dialysate is at the correct temperature and composition before starting therapy, and it provides a reliable baseline for comparison during the session. Documenting these pre-treatment values before treatment begins creates an official record and helps detect any changes or alarms that might indicate a malfunction. Checking only after readings change or only after treatment ends would miss early issues and fail to ensure patient safety.
