NRSG 550 MODULE 11 ATRIAL DYSRHYTHMIAS IN-CLASS QUESTIONS |
COMPREHENSIVE NURSING STUDY GUIDE, PRACTICE QUESTIONS &
ANSWERS 2026/2027
Which priority assessment finding would the nurse expect to see when caring for a client with sinus
tachycardia? Select all that apply.
A. Anxiety
B. Orthopnea
C. Restlessness
D. Shortness of breath
E. Decreased blood pressure - ✔✔B. Orthopnea
D. Shortness of breath
E. Decreased blood pressure
The priority assessment findings for clients with sinus tachycardia are orthopnea, shortness of breath,
and decreased blood pressure because these assessments can help in identifying the condition of the
client to start treatment. Anxiety and restlessness are observed in clients with sinus tachycardia, but they
are not priorities.
Compare the HR ranges and conduction pathways of:
• Sinus Tachycardia
• Atrial Fibrillation with Rapid Ventricular rate
• Supraventricular Tachycardia - ✔✔The presence of a P wave before each QRS complex indicates a
sinus rhythm; a heart rate greater than 100 regular beats per minute is referred to as tachycardia. Sinus
tachycardia stems from the sinoatrial noted. Atrial fibrillation has no well-defined P-waves, with an
irregularly irregular pattern of ventricular beats. A-fib stems from a path =way in the atrium and not
from the SA note. SVT rates tend to be between 140-180 and sometimes into the 200s, it is a recircuited
conduction coming from the atrial myocardium, not the sinoatrial node. Which action would the nurse
take when a client on a telemetry unit demonstrates a sinus rhythm with an occasional premature atrial
contraction (PAC)?
Which action would the nurse take when a client on a telemetry unit demonstrates a sinus rhythm with
an occasional premature atrial contraction (PAC)?
A. Continue to monitor the client.
B. Activate the Rapid Response Team.
C. Ensure that a defibrillator is available close by.
D. Give lidocaine intravenously as per protocol. - ✔✔A. Continue to monitor the client.
Occasional PACs (premature atrial contractions) are benign and will not affect cardiac output, but the
nurse will continue to monitor the client for increased numbers of PACs or other dysrhythmias.
Activation of the Rapid Response Team is inappropriate because there is no indication that the client is
