Generally the camera shows the points of interest. In this case, it's:
Seth wakes up in a well lit basement(sort of corridor) with many windows. He see's a phone across the room, though he's badly wounded he manages to crawl over to it, only to find it is out of power.
This description suggests a shot list that's already in your head.

This is all in you description of the scene, I've just highlighted the important bits of the description and turned them into the shot list (adding framing notes based on the intensity of the moment and the audiences need for relationship with the character/action). As filmmakers, we see scenes in our heads. Just be honest to that... it is the "VISION" that every one talks about filmmakers having. Write down the pictures in your head. Apply that to your location when you get there. On set, change your environment to match your vision...always return it to the state you found it, but move stuff around to suit the pictures in your head.
