Dysrhythmias NCLEX Practice Questions
1. The nurse is caring for an older adult client experiencing syncope, gener-
alized weakness, and dyspnea. Which dysrhythmia should the nurse suspect the
client is experiencing? (Select all that apply.)
First-degree AV block
Third-degree AV block
Mobitz I second-degree AV block Mobitz
II second-degree AV block
Sinus arrhythmia <Answer> Third-degree AV
block Mobitz I second-degree AV
block
Mobitz II second-degree AV block
Mobitz I second-degree AV block, Mobitz II second-degree AV block, and
gree AV block can cause syncope, generalized weakness, and dyspnea due to a
decreased cardiac output. Sinus arrhythmia and first-degree AV block do not cause
these clinical manifestations.
2. The nurse is caring for a client who is experiencing torsades de pointes.The
,nurse recognizes this condition as which type of dysrhythmia?
Ventricular tachycardia
Antrioventricular conduction block
Ventricular fibrillation
Junctional dysrhythmia <Answer> Ventricular tachycardia
Torsades de pointes is a type of ventricular tachycardia associated with long-QT
syndrome (a prolongation of the QT segment). Ventricular fibrillation is extreme
rapid, chaotic ventricular depolarization that causes the ventricles to quiver and cease
contracting; the heart does not pump. Junctional rhythms are those that
originate in AV nodal tissue. Antrioventricular conduction blocks are defects that dela
or block transmission of the sinus impulse through the AV node.
, 3. The nurse is caring for a pediatric client diagnosed with an atrial dys-
rhythmia. Assessment findings reveal rapid pulse with frequent episodes of
palpitations and decreased blood pressure. Which diagnosis should the nurse
anticipate?
Sick sinus syndrome
Premature atrial contractions
Wolff-Parkinson-White syndrome
Wandering atrial pacemaker <Answer> Wolff-Parkinson-White syndrome
The client's assessment findings support the diagnosis of Wolff-Parkinson-Whi
syndrome. The client's assessment findings do not support the other diagnoses.
4. The nurse is assessing a client admitted with a suspected stroke.Which
dysrhythmia would support this diagnosis?
Junctional escape rhythm
Mobitz II second-degree block
Torsade de pointes
Atrial fibrillation <Answer> Atrial fibrillation
Atrial fibrillation is characterized by disorganized atrial activity without discrete atrial
