Question

Quizplus · Accepted Answer

Factors that can impair the results of an electroencephalography (EEG) include recent consumption of coffee (A) and recent smoking (E) because both caffeine and nicotine can stimulate the nervous system, potentially altering the EEG readings. Dirty, oily hair (B) can also interfere with the electrodes' ability to make good contact with the scalp, affecting the quality of the EEG recording. Arrhythmias could potentially affect the interpretation of an EEG due to electrical interference, but they are not mentioned as a common factor in the question. Obesity (D) does not directly affect the EEG results, as EEG measures electrical activity in the brain and is not impacted by body fat.
