A Patient Who Is Being Admitted in ICU Requires a Finger

A patient who is being admitted in ICU requires a finger probe pulse oximeter. The priority nursing intervention for this patient is to:

A) Apply the sensor probe over a finger and cover lightly with gauze to prevent skin injury
B) Set alarms on the oximeter to at least 100 percent
C) Enquire if the patient has recently undergone a diagnostic test using intravenous dye
D) Remove the sensor from the finger between oxygen saturation readings
