Crushing Pot.Chloride 20 meq made by Ethex

My mother's nurses crush this potassium in applesauce or pudding or jelly to facilitate easier swallowing for her.  Some of this still sticks to her lips when she takes it in puddings, etc. Now her lips are quite swollen,almost burnt and bleeding. I believe the condition of her lips is directly related to and/or from crushing this med. Isn't there another form of Potassium that would be easier to swallow and comparable in pricing. She has had a stroke so has some dysphagia and they say it helps her to swallow easier.

Thank you!
