General impressions:
- well written and edited
- nice message
- flow and organization are well done

I have just a few minor suggestions:

Jimmy sat back up, and his pulse raced.
You might add a bit more tension by rewording to something like
Again, Jimmy sat up, his pulse racing.

Today, he would see the Mercury capsule that took Alan Shepard into space three years ago, the first American astronaut.
The descriptor is out of place.
Today, he would see the Mercury capsule that took Alan Shepard, the first American astronaut, into space three years ago.

He saw a bathroom attached to the room and stumbled through.
He saw is telling. You don't need to say he saw something and then acted.
He stumbled to the bathroom.

I think you can eliminate the *** after paragraph 5.

She heard sobbing from the bathroom and went to investigate. “Oh, Mr. Griffin.” Her favorite patient was huddled in a corner, shaking.
I'd suggest a bit of reorganization here:
From the bathroom came desperate* sobbing. Nora found her favorite patient huddled in the corner, shaking. "Oh, Mr. Griffin."
*or whatever adjective you feel appropriate.

Kyle joined her in the bathroom and lay the tablet down on top of the closed toilet seat.

Nice job! Keep up the good words.
