NCLEX-PN Practice Q 81
An 8-year-old admitted with an upper-respiratory infection has an order for O2 saturation via pulse oximeter. To ensure an accurate reading, the nurse should:
A. Place the probe on the child’s abdomen
B. Calibrate the oximeter at the beginning of each shift
C. Apply the probe and wait 15 minutes before obtaining a reading
D. Place the probe on the child’s finger
Correct Answer: D. Place the probe on the child’s finger
Option D: The pulse oximeter should be placed on the child’s finger or earlobe because blood flow to these areas is most accessible for measuring oxygen concentration.
Option A: The probe cannot be secured to the abdomen.
Option B: Pulse oximeter should be recalibrated before application.
Option C: Reading from a pulse oximeter is obtained within seconds, not minutes.
