SSM BASIC DYSRHYTHMIA RN EXAM
QUESTIONS & UPDATED CORRECT
ANSWERS
AV Node rate - correct answer ✔✔40-60 bpm
absolute refractory state, the ventricle - correct answer ✔✔would not respond
the primary direction of the mean cardiac vector - correct answer ✔✔Positive
The normal PR interval - correct answer ✔✔0.12-0.20 sec
Monitoring QT interval length is important because prolonged QT will increase the risk of
Torsadse. Select the three medications below that could increase a patient's risk of Torsade
VT/VF by prolonging the QTinterval? - correct answer ✔✔Erythromycin, Amiodarone, Haldol
Stimulation of the SA node by the sympathetic nervous system causes the heart rate to react in
which manner? - correct answer ✔✔Increases
Treatment of sinus tachycardia centers around which objective - correct answer ✔✔finding the
causative etiology for the dysrhythmia
If a temporary pacemaker fails to capture, which of the following steps may help improve the
capture rate? - correct answer ✔✔Make notification of failure to capture, anticipate increasing
the mA
identify the strip - correct answer ✔✔Atrial Fibrillation with ventricular paced beats
, in the strip below identify what is occurrring - correct answer ✔✔Pacemaker failing to sense
(nonsensing) and firing on the T wave
Which of the following rhythms would most likely require the use of an external pacemaker? -
correct answer ✔✔Third degree heart block, pt is dizzy, BP is low, complaining of chest pain.
An 81 year old male is in the unit with the diagnosis of heart failure. His ECG rhythm is irregular
with a narrow QRS. It is unclear if "P" waves are visible. One of the nurses believes the rhythm is
junctional rhythm. Another nurse believes the rhythm is atrial fibrillation. Since you are an
expert in rhythm interpretation, they ask your opinion. Which step would you take to help
clarify the issue? - correct answer ✔✔Change leads on the monitor to observe for "P" waves
13 describe the following strip? - correct answer ✔✔Pacemaker failing to capture (noncapture)
14 your patient with pneumonia is on oral amiodarone for a H/O sustained VT. You measure the
QT interval to be 0.50 up from 0.34 yesterday. You need to administer the first dose of
erythromycin this morning. Select the nursing action you would do before giving the
Erythromycin. - correct answer ✔✔Notify the MD of the QTinterval length before administering
Erythromycin.
15. Pacemaker operation can usually be described by the universal five position pacemaker
code, with the first tjhree letters being used most often (DDD,VVI). Identify the first three
positions in order of their occurence. - correct answer ✔✔Chamber paced, chamber sensed,
mode of response
ectopic beat - correct answer ✔✔originates at a site other than the normal pacemaker
p wave - correct answer ✔✔atrial depolarization
