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. Repositioning the pulse oximetry probe every 2 hours is unnecessary unless there is a concern about skin integrity or the accuracy of the reading. Continuous monitoring generally requires the probe to be in place for longer periods. B. Taping the wire to the palm of the hand is not recommended because it may cause skin irritation or pressure injury. The sensor should be placed on a finger or toe, where blood flow is easily accessible. C. Applying the sensor to the index fingernail is not ideal. Pulse oximetry is most accurate when applied to a finger or toe, but not directly on the nail itself. It should be placed on the skin near the nail. D. Warming the skin prior to probe placement is recommended to ensure better circulation and accurate pulse oximetry readings, especially in children or individuals with poor peripheral circulation.
