Exam 1: Dysrhythmias (NCLEX)
A 20-year-antique has a obligatory electrocardiogram (ECG) before collaborating on a university
football team and is discovered to have sinus bradycardia, price 52. Blood pressure (BP) is
114/fifty four, and the pupil denies any health troubles. What motion via the nurse is maximum
appropriate?
A.Allow the scholar to participate at the soccer team.
B.Refer the scholar to a cardiologist for similarly diagnostic trying out.
C.Tell the student to prevent playing right away if any dyspnea occurs.
D.Obtain greater distinctive information approximately the pupil's family fitness history. - ANS-A
In an aerobically skilled individual, sinus bradycardia is normal. The pupil's regular BP and poor
health history suggest that there is no want for a cardiology referral or for more specified data
about the family's health records. Dyspnea throughout an aerobic pastime which include football
is ordinary.
A customer admitted after using crack cocaine develops ventricular traumatic inflammation.
After determining unresponsiveness, which movement ought to the nurse take subsequent?
A. Defibrillate at 2 hundred J.
B. Establish IV access.
C. Place an oral airway and ventilate.
D. Start cardiopulmonary resuscitation (CPR). - ANS-A
Defibrillating is of precedence earlier than every other resuscitative measures in line with
Advanced Cardiac Life Support protocols.
A customer has frequent bursts of ventricular tachycardia at the cardiac monitor. A nurse is most
worried with this dysrhythmia because:
A) It is uncomfortable for the patron, giving a experience of forthcoming doom.
B) It produces a excessive cardiac output that fast leads to cerebral and myocardial ischemia.
C) It is nearly impossible to transform to a everyday sinus rhythm.
D) It can develop into ventricular fibrillation at any time. - ANS-D
Ventricular tachycardia is a lifestyles-threatening dysrhythmia that outcomes from an irritable
ectopic awareness that takes over as the pacemaker for the heart. The low cardiac output that
results can lead quick to cerebral and myocardial ischemia. Client's frequently enjoy a feeling of
impending demise. Ventricular tachycardia is handled with antidysrhythmic medicines or
magnesium sulfate, cardioversion (consumer awake), or defibrillation (lack of recognition),
Ventricular tachycardia can go to pot into ventricular defibrillation at any time.
, A customer with atrial fibrillation is receiving digoxin (Lanoxin). It is MOST essential for the
nurse to?
A. Record an EKG strip after administration
b. Monitor blood pressure every four hours
c. Maintain correct consumption and output records
d. Measure apical pulse previous to administration - ANS-D
Digitoxin decreases conduction velocity via the AV node and prolongs the refractory period. If
the apical coronary heart price is much less than 60 beats/minute, withhold the drug. The apical
pulse should be all for a stethoscope so that there could be no mistake about what the heart fee
absolutely is.
A client with atrial fibrillation with fast ventricular response has received medicine to sluggish the
ventricular rate. The pulse is now 88. For which additional remedy does the nurse plan?
A. Synchronized cardioversion
b. Electrophysiology research (EPS)
c. Anticoagulation
d. Radiofrequency ablation remedy - ANS-C
A patron's electrocardiogram strip indicates atrial and ventricular costs of eighty complexes in
step with minute. The PR interval is zero.14 2d, and the QRS complicated measures 0.08 2d.
The nurse interprets this rhythm is:
A) Normal sinus rhythm
B) Sinus bradycardia
C) Sinus tachycardia
D) Sinus dysrhythmia - ANS-A
A nurse assesses a client's electrocardiograph tracing and observes that not all QRS complexes
are preceded by using a P wave. How must the nurse interpret this remark?
A. The purchaser has hyperkalemia inflicting irregular QRS complexes.
B. Ventricular tachycardia is overriding the ordinary atrial rhythm.
C. The client's chest leads are not making sufficient touch with the skin.
D. Ventricular and atrial depolarizations are initiated from exceptional websites. - ANS-D
Normal rhythm indicates one P wave preceding each QRS complex, indicating that every one
depolarization is initiated at the sinoatrial node. QRS complexes with out a P wave imply a
specific source of initiation of depolarization. This finding on an electrocardiograph tracing isn't
an indication of hyperkalemia, ventricular tachycardia, or disconnection of leads.
A nurse cares for a purchaser with an intravenous transient pacemaker for bradycardia. The
nurse observes the presence of a pacing spike but no QRS complicated at the client's
electrocardiogram. Which motion have to the nurse take subsequent?
