Mrs. Franklin, an 81-year-old Alzheimer's patient hospitalized
under your care has been asked to participate in a clinical trial
testing a new drug designed to help improve memory. You were present
when the clinical investigator obtained a signed informed consent
from Mrs. Franklin a few days ago. However, when you visit Mrs.
Franklin today and ask her if she is ready to begin the study tomorrow,
she looks at you blankly and seems to have no idea what you are
What should you do?
