True or False: A manual conductivity reading should be taken when the machine is in bypass mode.

When assessing whether a manual conductivity reading should be taken while the machine is in bypass mode, it is essential to understand the function of bypass mode. Bypass mode generally means that the dialysis machine is not actively filtering blood; it is bypassing the dialysis process. Since conductivity readings are primarily used to monitor the dialysate composition and ensure that the machine is operating correctly during treatment, taking a manual conductivity reading in bypass mode is not applicable.

In bypass mode, the machine is not functioning in the capacity that would require a conductivity analysis; hence, such readings would not provide useful information regarding the operation of the machine or the safety of the treatment being administered. Therefore, the assertion that a manual conductivity reading should be taken during this mode is false.
