Question 1
A telemetry monitor reveals a regular rhythm with
a heart rate of 72 beats/minute. The P waves are
upright, identical, and precede every QRS complex.
The PR interval measures 0.16 seconds, and the
QRS complex measures 0.08 seconds. How should
the nurse interpret this rhythm?
A) Sinus Bradycardia
B) Normal Sinus Rhythm
C) First-Degree AV Block
D) Sinus Tachycardia
Answer: B) Normal Sinus Rhythm
Rationale: Normal Sinus Rhythm (NSR) is
,characterized by a regular rate between 60 and 100
beats/minute. All P waves must be uniform, upright,
and present before every QRS complex. The
standard PR interval ranges from 0.12 to 0.20
seconds, and the standard QRS duration is less than
0.12 seconds. This tracing perfectly meets all
normal parameters.
Question 2
The nurse notes a regular cardiac rhythm running
at a rate of 115 beats/minute. The P waves are
uniform and precede every QRS complex with a
stable PR interval of 0.14 seconds. The QRS width is
0.06 seconds. Which rhythm is present?
A) Atrial Flutter
B) Supraventricular Tachycardia
C) Sinus Tachycardia
D) Ventricular Tachycardia
Answer: C) Sinus Tachycardia
Rationale: Sinus Tachycardia originates from the
sinoatrial (SA) node and exhibits all the regular
characteristics of normal sinus rhythm, except the
discharge rate exceeds 100 beats/minute (typically
ranging between 101 and 150 beats/minute). The
,presence of clear, normal P waves rules out atrial
flutter and generic SVT.
Question 3
An adult patient's telemetry strip shows a regular
heart rate of 48 beats/minute. Upright P waves are
present before every QRS complex, the PR interval
is a constant 0.18 seconds, and the QRS complex is
0.08 seconds wide. What is the correct
interpretation?
A) Sinus Bradycardia
B) Junctional Rhythm
C) Second-Degree AV Block Type I
D) Idioventricular Rhythm
Answer: A) Sinus Bradycardia
Rationale: Sinus Bradycardia fulfills all standard
criteria for normal sinus rhythm (upright P waves,
constant PR intervals, narrow QRS), but features a
heart rate falling below 60 beats/minute. Junctional
and ventricular rhythms would lack normal, upright
sinus P waves.
Question 4
A patient’s cardiac monitor exhibits an irregular
rhythm. The P-P intervals vary across the strip,
, lengthening and shortening in sync with the
patient’s respiratory cycle. The P waves, PR
intervals, and QRS complexes are otherwise
normal. Which condition does this reflect?
A) Sinus Arrest
B) Premature Atrial Complexes
C) Atrial Fibrillation
D) Sinus Arrhythmia
Answer: D) Sinus Arrhythmia
Rationale: Sinus Arrhythmia is a normal
physiological variation frequently observed in young
adults and healthy individuals. The sinoatrial node
fires irregularly in relation to respiration, causing
the heart rate to increase during inspiration and
decrease during expiration. The underlying
morphology remains entirely normal.
Question 5
While scanning a telemetry strip, the nurse
observes a rhythm that is fundamentally regular but
interrupted by an early, abnormally shaped P wave.
This early P wave is followed by a normal, narrow
QRS complex and a non-compensatory pause. What
is this ectopic beat?
A) Premature Ventricular Complex (PVC)
