To be honest, I wasn't sure I was a cruise person. I live in a crowded city; the last thing I usually want from a holiday is to be confined in a small space. A bigger concern was my repaired tendon, which would certainly be tested by six days of yoga camp.
In Florida, Physician Assistants (PAs) can prescribe, order and dispense mediations. However, PAs are not permitted to prescribe the medicinal drugs listed in the formulary. In order for a PA to prescribe, the supervising physician must delegate such authority to the PA.
CNA 's should not give any medications to the patient , yet, if certified they can assist the patient in self administering the medication. Even when certified, the medication should be pre-measured and given to them by a nurse or doctor. This sounds like the situation you have described and is OK. Medical Assistants, who have more educaiotn than the CNA, can give shots under supervision of an on-duty doctor.
