1. A nurse is monitoring a client on telemetry. Which
lead is best for detecting atrial arrhythmias?
A) Lead II
B) Lead V1
C) Lead aVF
D) Lead V5
Answer: B
Rationale: V1 is most sensitive for atrial activity and
distinguishing P waves.
,2. A client’s ECG shows a regular rhythm, rate 80,
upright P wave before each QRS, PR 0.16 sec, QRS
0.08 sec. What is the rhythm?
A) Sinus bradycardia
B) Normal sinus rhythm
C) Sinus tachycardia
D) Atrial flutter
Answer: B
Rationale: Rate 60-100, regular, normal P-QRS-T, PR
0.12-0.20, QRS <0.12.
3. A client develops a sudden onset of palpitations.
ECG shows a narrow-complex tachycardia at 180 bpm,
regular, no visible P waves. What is the most likely
rhythm?
A) Ventricular tachycardia
2
,B) Supraventricular tachycardia (SVT)
C) Atrial fibrillation
D) Sinus tachycardia
Answer: B
Rationale: SVT is a regular narrow-complex tachycardia
with rates 150-250 bpm, often no visible P waves.
4. A client in SVT is unstable with a blood pressure of
80/50 mmHg. What is the priority intervention?
A) Administer adenosine IV
B) Synchronized cardioversion
C) Defibrillation
D) Start CPR
Answer: B
Rationale: Unstable SVT requires immediate
synchronized cardioversion.
3
, 5. A client’s ECG shows chaotic, irregular baseline with
no discernible P waves and an irregularly irregular
ventricular response. What is the rhythm?
A) Atrial flutter
B) Atrial fibrillation
C) Ventricular tachycardia
D) Sinus arrhythmia
Answer: B
Rationale: Atrial fibrillation has no P waves, irregularly
irregular rhythm.
6. A client with atrial fibrillation is on warfarin. The
INR is 1.5. What should the nurse anticipate?
A) Continue current dose
