CET 2020 Study Guide Exam Questions
With Complete Correct Solutions.
What should you do if a pt is experiencing angina during a treadmill test? - Answer Stop the test, Check
the patient first, then notify the MD (doctor)
What would be a contraindication to a stress test? - Answer an MI (myocardial infarction) or CHF
(congestive heart failure); (anytime you don't want to put stress on the heart)
Where do you attach the electrodes for telemetry/Holter (ambulatory) monitoring? - Answer The chest
Are there hygiene restrictions during Holter monitor testing? - Answer yes (e.g. don't shower)
What type of activities need to be documented in the diary during a Holter monitor? - Answer Any
activity usual & unusual
While doing an EKG you see a flat line tracing, what should you do first? - Answer Assess the patient
What's can cause alternating current (electrical) interference artifacts? - Answer anything electrical
Heart rate changes associated with respiration are described as __________________. - Answer
regularly irregular rhythm
Patient is asymptomatic (not having any symptoms) during a stress test, what should you do? - Answer
Continue the test
The septal wall of the heart is viewed by which leads? - Answer V1, V2
QRS complex width of < 3 small squares. Is this normal conduction? - Answer yes (< 0.12)
, Which waveform represents atrial conduction on an EKG? - Answer p wave
Dyspnea has to do with which vital sign? - Answer Respirations
How do you measure the PR Interval? - Answer beginning of P wave to beginning of QRS complex
With the Bruce protocol stress test, how often do you record pt BP? - Answer every 2.5 to 3 min / EKG
done every 5/10/15 minutes
Which wave differentiates idioventricular rhythm from junctional escape rhythm (both rhythms are slow
and have no P waves)? - Answer QRS
How many electrodes are used for Holter monitoring? - Answer 3-5
Make sure you can identify atrial flutter on a rhythm strip. - Answer ▪︎saw tooth like p waves
▪︎ratio can vary from 2:1 to 3:1 depending on av conduction
▪︎atrial rate is fast 250-300 bpm
▪︎ventricular rate slower due to (protective) refractory period
▪︎ventricular rate is normally regular but can be irregular
▪︎no p-r interval
▪︎no T wave
Report _________________ when pt is doing a stress test. - Answer syncope (fainting) or any unusual
findings
What does a QRS complex width of 0.20 seconds indicate? - Answer delayed ventricular conduction
Which control on the EKG machine increases or decreases the amplitude (voltage) of the tracing? -
Answer gain
