1. Question
A nurse is assessing an electrocardiogram rhythm strip. The P waves and QRS complexes are regular.
The PR interval is 0.16 second, and QRS complexes measure 0.06 second. The overall heart rate is 64
beats per minute. The nurse assesses the cardiac rhythm as:
Incorrect
Correct Answer: A. Normal sinus rhythm
, Measurements are normal, measuring 0.12 to 0.20 second and 0.4 to 0.10 second,
respectively. Sinus rhythms originate in the SA node. The SA node is located in the right
atrium and is the heart’s natural pacemaker. The normal rate of the SA node is between 60
and 100. On ECG, sinus rhythm is represented by monomorphic P waves before each QRS
complex and is regular.
Option B: Sinus bradycardia is a cardiac rhythm with appropriate cardiac muscle
depolarization initiating from the sinus node generating less than 60 beats per minute
(bpm). The diagnosis of sinus bradycardia requires visualization of an electrocardiogram
showing a normal sinus rhythm at a rate lower than 60 bpm. Option C: Sick sinus
syndrome, also known as sinus node dysfunction (SND), is a disorder of the sinoatrial
(SA) node caused by impaired pacemaker function and impulse transmission producing
a constellation of abnormal rhythms. These include atrial bradyarrhythmias, atrial
tachyarrhythmias and, sometimes, bradycardia alternates with tachycardia often
referred to as “tachy-brady syndrome.”
Option D: First-degree atrioventricular (AV) block is a condition of abnormally slow
conduction through the AV node. It is defined by ECG changes that include a PR
interval of greater than 0.20 without disruption of atrial to ventricular conduction.
2. Question
A nurse notices frequent artifacts on the ECG monitor for a client whose leads are connected by
cable to a console at the bedside. The nurse examines the client to determine the cause. Which of
the following items is unlikely to be responsible for the artifact?
