You can be assigned Oxygen Saturation (and report if <95%) either one of the three places on your Kardex: 1. Vital Signs 2. Respiratory Assessment 3. Oxygen Management
This does not mean that you have to take the oxygen saturation multiple times but you can use the oxygen saturation measurement that was taken in the narrative notes for the other section as well.
Now, having said that, this does not excuse you from being a prudent nurse and doing above and beyond what is required. My question is... what is the most accurate form of assessment of patient's response to activity? Fluctuations in O2 sat. That's right. If you wanted to, you can check the O2 sat before the patient gets out of bed, and then right after the activity for the response. The other observations by themselves will suffice too such as dyspnea with ambulation etc... but the most accurate one would by far be O2 saturation.
And don't forget to chart this in your narrative notes if you are assigned either Respiratory assessment or O2 Management - response to activity. O2 Man - FAN SHOP F - Flow rate/route A - Response to activity during the PCS N - Nares/ears tubing intact and not irritating the skin
S - Safety concerns H - Humidification? O - Oxygen status (CCCO - color, cap refill, clubbing, O2 saturation) P - Position (did you help the patient in a position that helps them with oxygen exchange? Raised head of the bed)

T - Tolerate assessment/activity? This is where you will mention whether or not patient had a drop in O2 sat or had dyspnea.
