Definition of Electroencephalography
The study of the electrical activity of the brain. The basis for other tests.
Definition of Interpreting Physician
typically, a neurologist who reads the EEG and interprets the results.
A neurologist measures and secures the application of
Electrodes
A neurologist acts as a link between the
Doctor and Patient
A neurologist preforms duties with
Accuracy and Honesty
A neurologist maintains patient
Confidentiality and Safety
Understand the scope of practice and never make a
official reading or report
EEGs are used for assessing conditions like
comas, stroke, tumors, head trauma, and toxic/metabolic disorders
EEGs are utilized in
Surgical Monitoring
The first step in setting up a patient for an EEG involves
Mapping the head
Duties of EEG tech
Measure head, Record EEG, Report findings to IP, and record history
Ethics
Accurate and honest, Patient Confidentiality, Patient safe, scope of care
What is the Primary Purpose of the international 10-20 system of measurement?
To standardize EEG measurements worldwide
Which landmark is defined as the bridge of the nose?
Nasion
During which step do you measure from the left pre-auricular point to the right pre-auricular point across the top of the head?
Step 3: Measure Coronal Plane
How much distance is marked from the Nasion and inion to find FPZ and Oz respectively?
10%
Which Plane measurement involves marking halfway points between Fp1, C3, and O1?
Left Parasagittal Plane
What happens if the electrodes are placed too close together, such as between F4 and C4?
The EEG amplitude is reduced
Why is it important for an EEG technologist to use the correct measuring method?
To ensure consistent interpretation across all EEGs
True or False: Before placing electrodes, the skin must be prepped with an approved skin cleanser
True
True or False: It is recommended to use excessive paste when applying paste-type electrodes to ensure they stay on longer
False
True or False: Collodion is quicker to apply than paste and has no noxious smell
False
True or False: Collodion can be a fire hazard, so it should not be used near ignition sources
True
True or False: Paste-type electrodes are ideal for a long-term monitoring as they stay on very well for extended periods
False
True or False: When prepping the skin, you should rub the entire cross-mark off the ensure proper electrode contact
False
True or False: Collodion application requires the use of forced air to dry the collodion on the electrode
True
True or False: After applying paste-type electrodes, you should cover them with gauze, cotton, or paper tape to secure them
True
True or False: The main concern during electrode application is skin breakdown, which can be prevented by gentle prepping
True
True or False: Acetone, used for removing collodion, should be stored in a fireproof cabinet due to its flammability
True
True or False: Collodion application does not require any special ventilation because it has no strong smell
False
True or False: Proper skin prep includes wiping off any excess prep with a damp washcloth or alcohol wipe
True
