Final answer:
For the 49-year-old patient with low oxygen saturation, the nursing problem is Impaired Gas Exchange, and the goal is to maintain oxygen saturations above 92% over the next 24 hours.
Step-by-step explanation:
For patient #2 (LV, the 49-year-old male who was found unresponsive with a low oxygen saturation), the nursing problem can be formulated in NANDA format as follows: Impaired Gas Exchange related to decreased oxygen-carrying capacity of the blood secondary to hypoventilation as evidenced by repeated desaturations when removing the oxygen mask, with oxygen saturation dropping to the 70s. The goal for this patient is: The patient will maintain oxygen saturations above 92% at all times over the next 24 hours.
