A nurse is obtaining an oxygen saturation on a client. Which of the following actions should the nurse take?

A. Waiting only 10 seconds may not allow the pulse oximeter to stabilize; readings typically stabilize within 30–60 seconds. B. Choosing a finger with a capillary refill less than 2 seconds ensures adequate peripheral perfusion, which is necessary for an accurate oxygen saturation reading. C. Placing the sensor on the same extremity as a blood pressure cuff can produce inaccurate readings due to intermittent compression. D. The sensor does not need to be relocated every 8 hours unless there are concerns about skin integrity, pressure, or circulation.
