A patient needs to undergo a diagnostic test. He is given a sedative to help him relax for the test. Fifteen minutes after administering the medication, you notice the consent form is not signed. What should you do? What might occur with the diagnostic test? Is there any situation in which a consent form can be signed after a person receives a mind altering/relaxing medication?
