Prayed with a patient for the first time today.  Not sure if it was exactly allowed (but don't think it's not allowed either?) but it seemed like she really needed it and she had faith, so I offered.  She was the type of patient who no matter what you tried, you would just be going in circles.  Nothing could really be done for her unless her spirit stopped hurting.  In her case, it was the most important part of her symptoms.
