A patient who is being admitted in ICU requires a finger probe pulse oximeter. The priority nursing intervention for this patient is to:
  1. Apply the sensor probe over a finger and cover lightly with gauze to prevent skin injury
  2. Set alarms on the oximeter to at least 100 percent
  3. Enquire if the patient has recently undergone a diagnostic test using intravenous dye
  4. Remove the sensor from the finger between oxygen saturation readings
Explanation
Answer- C - The priority nursing intervention for this patient is to enquire if the patient has recently undergone a diagnostic test using intravenous dye. The pulse oximeter may record inaccurate readings if dye has been used for a diagnostic test. Dyes contain colored substances that tint the blood and give rise to inaccurate readings.
