A Patient Receiving Mechanical Ventilation Is Being Continuously Monitored for Oxygen

question 15

Multiple Choice

A patient receiving mechanical ventilation is being continuously monitored for oxygen saturation measured by pulse oximeter (S_pO₂) for the last 48 hours.When initially applied,the S_pO₂ and the arterial oxygen saturation (S_aO₂) ,as well as the pulse on the pulse oximeter,ECG,and manual pulse,were consistent.During clinical rounds,the respiratory therapist notices that although the probe is appropriately placed and capillary refill is normal,the S_pO₂ reading is down to 90% from 95%.The most appropriate immediate action is to do which of the following?

• A) Replace the probe.
• B) Reposition the patient.
• C) Draw an arterial blood gas.
• D) Move the probe to a different site.
