The difference in a rectal temp and an enema is the enema is somewhat bigger, and you are pushing fluid into a vault that you can't see and it could be damaged, perforated, etc. If a patient is constipated to the extreme that they need an enema (oral agents don't work) they should be assess by a nurse (if in an institution) or md if at home, to rule out adverse conditions. If this is done and they warrant an enema that would be the time to administer one not leave it for a cna to do since it is an evasive procedure. But, I must say that I don't feel a cna should do a rectal temp either d/t it is an evasive procedure also.
No, a CNA cannot give enemas or medication. It has to be done by a nurse. With the enema your putting something inside the body that has to be monitored, and with medication CNA does not have the training to know everything about a certain drug.
In the home, if a patient codes during your shift ,CNA must initiate CPR unless there is a no code order?
