Diagnostic Tests for Seizures
Diagnostic Tests for Seizures ( 5 Questions)
A nurse is caring for a patient who is scheduled for a magnetic resonance imaging (MRI) scan of the brain. Which of the following instructions should the nurse provide to the patient?
Choice A is wrong because it is a correct instruction that the nurse can provide to the patient. The MRI can reveal structural abnormalities or lesions that may cause seizures, such as tumors, strokes, infections, or malformations¹².
Choice B is wrong because it is also a correct instruction that the nurse can provide to the patient. The MRI can detect abnormal patterns or discharges that indicate seizure activity, especially if it is a functional MRI (fMRI) that can measure the metabolic changes in the brain when the patient performs certain tasks¹².
No explanation
Choice D is wrong because it is partly correct and partly incorrect. The MRI can be done in a clinic or hospital, depending on the purpose and duration of the test, but not at home¹³. MRI machines are large and expensive devices that require special facilities and trained staff to operate them¹.
This instruction is incorrect and should not be provided to the patient, because an MRI scan of the brain does not measure the electrical activity of the brain or use electrodes. This is a description of an electroencephalogram (EEG) test, which is a different procedure¹².
