10 k ohms
According to ACNS Guidelines, the recording must include this minimum patient
information on the recording: (check all that apply) - answertime & date of recording
age
patient name
unique identifier
technologist
According to ACNS Guidelines, the data sheet should not include: indications for
recording, symptoms of events and their frequency, skull defects, medication, date &
details of last seizure, behavioral state pre-medication to induce sleep, sleep deprivation
handedness, time of last meal, other test results modifications to electrode placement,
relevant medical history. - answerFALSE
According to ACNS Guidelines, the technologist's notations should include: (check all
that apply) - answerany movement or clinical seizure activity (or lack there of)
, careful observation of the patient with frequent notations
level of consciousness (awake, drowsy, sleeping, or comatose)
A system for assessing a patient's level of consciousness is called _____. -
answerGlasgow Coma Scale
Documentation of the record includes annotations of which of the following items?
(select all that apply) - answerobservations of clinical signs during any seizures or
documentation of lack there of.
montage changes, activation procedures, and parameter changes such as filters or
sensitivity if this is not automatically noted by the instrument
Explaination of artifacts and indication of how each was corrected
changes in patient status including state of awareness, level of consciousness,
position, behavior, and level of cooperation.
What does HIPAA stand for? - answerHealth Insurance Portability and Accountability
Act
The first-ever federal privacy standards to protect patients' medical records and other
health information provided to health plans, doctors, hospitals and other health care
providers took effect on April 14, 2003 and is called _____. - answerHIPPA
When testing for level of awareness during 3 Hz Spike and Slow wave during HV, the
technologist should _______. - answerprompt the patient during the discharge with a
word to remember and ask them to repeat it later
The information associated with the record should include, as a minimum, (check all
that apply) - answerthe date of the recording
the name or initials of the technologist
the name and age of the patient
an identification number
A Basic Data Sheet, associated with every record, should include (select all that apply) -
answerany relevant additional medical history
the time and date of the last seizure/episode (if any)
indication for the EEG (including description of symptoms or events, and their
frequency)
a list of all medications the patient has been taking (including premedication given to
induce sleep during the EEG
the behavioral state of the patient
presence and location of any skull defects
