The patient scheduled for a PET (positron emission tomography) scan of the brain asks if there is any special preparation for the test. The nurse correctly responds with which statement(s)? (Select all that apply.)
a. "There is no special preparation involved with this test since it is noninvasive."
b. "You should avoid any tranquilizers or sedatives the night before and the day of the test."
c. "You will need to sign a consent form for this test to be performed."
d. "You will have two IVs inserted for the examination."
e. "You should wait to empty your bladder once the test is completed."
B, C, D
During a PET scan, radioactive material is given through an intravenous (IV) line and provides differing color in areas of cellular activity. A consent form is required because this is an invasive test, and tranquilizers and sedatives should be avoided because this PET scan is of brain activity. The test requires insertion of two IVs. Obviously, special preparation is indicated, and the patient should empty his bladder before the test begins.
