A patient is connected to a 12-lead ECG monitor and pulse oximeter before an exercise test.The HR displayed by the ECG monitor is 97;the pulse oximeter reads an HR of 141 with an SpO₂ of 85%.Which of the following would be the most appropriate action? A) Move the pulse oximeter sensor to an alternate site. B) Check all ECG lead wires for a good connection. C) Obtain an arterial blood gas sample as quickly as possible. D) Document the readings and proceed with the test.

The pulse oximeter reading of 141 is unlikely to be accurate, as it is much higher than the ECG reading of 97. Moving the pulse oximeter sensor to an alternate site may provide a more accurate reading. Checking the ECG lead wires is also important, but less likely to affect the pulse oximeter reading. Obtaining an arterial blood gas sample is not necessary at this point. Documenting the readings and proceeding with the test without investigating the discrepancy may put the patient at risk.
