We have that rule about having to witness the self-administration of any medication here where I work too. It was set up by a pharmacy committee and it is hard and fast/set in stone. HOWEVER, we do get around it a little bit. We require that the CF doctor specify which patients may self-administer. (Honestly, they do not want everyone to self-administer because they want the RT to have time to get to know the patients and it takes time to find those tiny flaws in technique, which we discover while conversing with and administering treatments to our patients). The doctor writes an order stating "OK for patient to self-administer RT medications", or something similar. Then, we go by and see the patient to find out when they plan to do their treatments. We come back around that time and scan the meds into the computer and give them to the patients. Then, we do an opening assessment of breath sounds, pulse, pulse ox, and respiratory rate. After an appropriate amount of time, we come back and do a closing assessment. (This is an exception to our self-administration rule and is only allowed with CF patients). At that time, we dispose of the nebulizer(s) which was/were used for Albuterol, Saline, Budesonide, etc., and either wash and cold sterilize the other nebs or go over the patient's cleaning and sterilization technique to be sure that they are going to be able to adequately clean and sterilize their own equipment.
Unfortunately, the RTs here have a full load plus the CF patients that are on their floor. (We have 2 primary pulmonary floors, so this is where the CF patients will be located.) We send other RTs to help out when they are through with their rounds, but 1st rounds are killer for everyone because all of the Q3, Q4, Q6 and Q12 treatments are due first rounds and you cannot be everywhere at once! Fortunately, most of our CF patients would rather we wait until 2nd rounds (11am) to see them and that is easier.
