I Just Saw My Friend In The Hospital. She Has

I just saw my friend in the hospital. She has been hospitalized for about three weeks or more. She has dementia and is in her mid seventies. She was hospitalized after an episode of aggressive behavior and hitting her head on the ground. She has been on prednisone for a long time for arteritis. They are treating her with Haldol at last three times a day, in addition to other meds. For the past few days she isn’t hardly waking up or coherent. Should we question her treatment.
