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?

A. The sensor should be applied to a site where it can provide accurate readings, but not specifically to the fingernail. B. Repositioning the probe every 2 hours helps prevent skin irritation and ensures accurate readings. C. Warming the skin prior to probe placement is not necessary and is not standard practice unless the client has circulatory compromise. D. Taping the wire to the palm of the hand is not necessary and may cause discomfort or interfere with accurate readings.
