Option I, checking the function of the PCO₂ electrode, will help identify any issues with the electrode that could be causing the high results. Option III, repairing or replacing any failed components, can address any issues with the equipment that could cause high results. Option II, rerunning the control sample a second time, may help to confirm the high results and check for any errors in the first run. Therefore, options I and III are the best choice to address the issue. Option II may not provide a resolution to the issue but can be done as a secondary step.
