PREPARATION 2026
◉ C. Answer: A client with atrial fibrillation with rapid ventricular
response has received medication to slow the ventricular rate. The
pulse is now 88. For which additional therapy does the nurse plan?
a. Synchronized cardioversion
b. Electrophysiology studies (EPS)
c. Anticoagulation
d. Radiofrequency ablation therapy
◉B
The nurse needs to assess the client to determine stability before
proceeding with further interventions. If the client has a pulse and is
relatively stable, elective cardioversion or antidysrhythmic
medications may be prescribed.. Answer: The nurse is caring for a
client with unstable angina whose cardiac monitor shows
ventricular tachycardia. Which action is appropriate to implement
first?
a. Defibrillate the client at 200 J.
b. Check the client for a pulse.
,c. Cardiovert the client at 50 J.
d. Give the client IV lidocaine.
◉A
Defibrillating is of priority before any other resuscitative measures
according to Advanced Cardiac Life Support protocols.. Answer: A
client admitted after using crack cocaine develops ventricular
fibrillation. After determining unresponsiveness, which action
should the nurse take next?
a. Defibrillate at 200 J.
b. Establish IV access.
c. Place an oral airway and ventilate.
d. Start cardiopulmonary resuscitation (CPR).
◉D
Clients at risk for bradydysrhythmias should avoid bearing down or
straining during a bowel movement; the Valsalva maneuver can
cause bradycardia. Taking a stool softener helps to prevent this..
Answer: In teaching clients at risk for bradydysrhythmias, what
information does the nurse include?
a. "Avoid potassium-containing foods."
b. "Stop smoking and avoid caffeine."
, c. "Take nitroglycerin for a slow heartbeat."
d. "Use a stool softener."
◉C
A P wave is generated by the SA node and represents atrial
depolarization.. Answer: The nurse is determining whether the
client's rhythm strip demonstrates proper firing of the sinoatrial
(SA) node. Which waveform indicates proper function of the SA
node?
a. The QRS complex is present.
b. The PR interval is 0.24 second.
c. A P wave precedes every QRS complex.
d. The ST segment is elevated.
◉ ABE
The Valsalva maneuver stimulates the vagus nerve, causing
bradycardia. Inferior wall MI is a cause of bradycardia and heart
blocks. Calcium channel blockers such as diltiazem may cause
bradycardia.. Answer: The nurse is caring for a client who has
developed a bradycardia. Which possible causes should the nurse
investigate? Select all that apply
a. Bearing down for a bowel movement
