A patient for whom the nurse is caring has positron emission tomography (PET) scheduled. In preparation, what should the nurse explain to the patient?
A) The test will temporarily limit blood flow through the brain.
B) An allergy to iodine precludes getting the radio-opaque dye.
C) The patient will need to endure loud noises during the test.
D) The test may result in dizziness or lightheadedness.
Ans: D
Feedback:
Key nursing interventions for PET scan include explaining the test and teaching the patient about inhalation techniques and the sensations (e.g., dizziness, light-headedness, and headache) that may occur. A PET scan does not impede blood flow through the brain. An allergy to iodine precludes the dye for an MRI, and loud noise is heard in an MRI.
