In order to obtain an accurate oxygen saturation reading, on which location will the nurse place the probe?
1. On a spot that the client cannot move
2. On the client's nondominant hand
3. On the client's dominant hand
4. On a site that is well perfused and warm on the client
Correct Answer: 4
The nurse should place the probe on a site that is well perfused and warm because the probe works by measuring blood flowing through the site. The most common site for measuring oxygen saturation is the finger, and the probe can be placed on the dominant or nondominant hand. The client should be asked not to move the finger until the reading is obtained. If the oximeter probe is to remain in place, the position should be changed periodically to avoid injury.
