A nurse is caring for a school-age child who has a new prescription for continuous pulse oximetry monitoring. Which of the following actions should the nurse take?

Choice A reason: Taping the wire to the palm of the hand can be uncomfortable for the child and may interfere with blood flow. Choice B reason: Warming the skin prior to probe placement is not a standard practice for pulse oximetry monitoring. Choice C reason: Applying the sensor to the index fingernail is not a recommended site for pulse oximetry monitoring in children. Choice D reason: Repositioning the probe every 2 hours helps to prevent skin breakdown and ensures accurate readings over time. This is a standard practice in pulse oximetry monitoring.
