Which site is NOT listed as an alternative location for a pulse oximeter when finger readings are unreliable?

• A. In The Mouth Clipped To The Cheek
• B. On A Toe
• C. On The Nose
• D. On The Earlobe

Answer: (D)

When finger readings aren’t reliable, clinicians look for alternative sites to place the pulse oximeter so oxygen saturation can still be monitored without disturbing the procedure. In the context of oral sedation monitoring, common alternatives include placing the sensor in the mouth clipped to the cheek, on the toe, or on the nose. These sites are chosen because they can provide stable readings even when the fingers aren’t workable due to access or movement around the mouth and airway. The ear lobe, while a familiar site for many pulse oximeters in other settings, is not listed as an alternative location in this particular context. That makes it the site that isn’t included among the alternatives described here.
