Which of the following medications should be held 24-48 hours prior to an electroencephalogram (EEG)?
Correct answer
D
Rationale
Anticonvulsants like Dilantin should be held 24-48 hours before an EEG to prevent interference with the test results. Medications such as tranquilizers, barbiturates, and other sedatives should also be avoided. Lasix, Cardizem, and Lanoxin do not belong to these categories and are not known to interfere with EEG results.
