Ideally, write in the medication log
a. client
b. home health aide
c. physician
d. nurse

I think it's the home health aide, because they can be there to see when and what medicane is given. The client could be too sick to write, and the physician isn't always there. And the nurse sees so many other patients to have enough time. I think it's the home health aide.
