What should the nurse do to ensure an accurate reading of an 8-year-old admitted with an upper-respiratory infection has an order for O2 saturation via pulse oximeter?

Place the probe on the child’s finger

The pulse oximeter should be placed on the childs finger or earlobe because blood flow to these areas is most accessible for measuring oxygen concentration. Placing the probe on the childs abdomen is incorrect because the probe cannot be secured to the abdomen. Recalibrating the oximeter at the beginning of each shift is incorrect because it should be recalibrated before application. Applying the probe and wait 15 minutes before obtaining a reading is incorrect because a reading is obtained within seconds, not minutes.
