AACN ECG Test 1 Foundation
1. Sinus arrest may be life threatening if atrial activity is not restarted.: True
2. Which of the following is NOT a common cause of third-degree AV block?-
: Hypertrophic obstructive cardiomyopathy
3. All of the following are findings of Second Degree AV BlockType I except:-
: Frequent idioventricular escape beats
4. You recently take over care of Ms. Alrashid, a 34 year old Egyptian womanadmitted to
your unit.Thirty (30) minutes ago she convertsfrom SinusRhythmto atrial tachycardia. What
symptoms are she likely to report when you go in to assess her, and why?: She feels weak and
dizzy because her heart rate is so fast ventricular filling time is decreased.This is likely to be
why she is hypotensive.
5. A rhythm strip that has consistent R-R intervals and P-P intervals is said tobe a regular
rhythm.: True
6. All second degree AV blocks are the result of failure of the impulse gener-ated by the SA
node to reach the AV node.: False
7. Which of the following is the rate for a junctional escape rhythm?: 40 - 60beats per minute
8. Multifocal atrial tachycardia, also known as Wandering Atrial Pacemaker, isidentified by::
Irregular R-R interval and P waves of different shapes
9. In a typical 5 lead configuration where is the white electrode (RA) placed?-
: The white electrode (RA) is placed at the infraclavicular fossa, close to the rightshoulder.
10. Atrial Fibrillation is identified by all of the following except:: B) Normal P-Pinterval
11. In a patient with a Second Degree AV block, you understand that impulsescoming from
the SA node are randomly being blocked at .: A p12. When selecting a lead to monitor which of the following should be pre-sent?: A large,
distinct R wave
13. Using the sequence method, there is an R wave that hits on a dark line, thenext R wave is 4
boxes later.The rate for this strip is:: 75 beats/min
14. The PR interval: (Select all that apply): Includes the P wave and the PRsegment
Is measured from the beginning of the P wave to the beginning of the QRSIs typically 0.12 -
0.20 seconds (120 - 200 msec)
15. What bipolar lead is similar to V1?: Lead MCL1
16. You are caring for a 16 y/o female in the emergency department. She pre-sented with
complaints of chest pain with sudden movement or when taking
a deep breath. The physician asked for her to be placed on a cardiac monitorand to obtain a 12
Lead ECG. She isin sinusrhythm but on closer observationyou notice her HR drops from 80 to
72 during expiration, then increases to 80 again with inspiration.You identify the rhythm as , and yo17. R-R interval helps determine ventricular rates. Atrial rates are determinedusing which of
the following?: P to P interval
18. Mr. Pratz is a 68 y/o male admitted to the hospital with a newly diagnosed
