A nurse is caring for a client who is in pulseless ventricular tachycardia (V-Tach). The nurse recognizes the need for which priority intervention?

Immediate Defibrillation

Synchronized Cardioversion

Perform CPR

Repeat electrocardiogram (ECG)

Answer and Explanation

The Correct Answer is A

A. Defibrillation is the priority intervention for pulseless ventricular tachycardia, as it can restore a normal rhythm. It should be performed as soon as possible.
B. Synchronized cardioversion is used for hemodynamically unstable tachyarrhythmias with a pulse, not for pulseless V-Tach.
C. CPR should be initiated if a defibrillator is not immediately available, but defibrillation is the definitive treatment.
D. Repeating an ECG does not address the immediate life-threatening situation.

Correct Answer is D

Explanation

A. Muffled heart sounds are associated with pericardial effusion or tamponade, not infective endocarditis.
B. Palpitations can occur but are not a classic sign of infective endocarditis.
C. Hives suggest an allergic reaction, not endocarditis.
D. Splinter hemorrhages (tiny, red-brown streaks under the nails) are a classic sign of infective endocarditis due to small emboli from the infected heart valves.

A. Complete Heart Block B. Sinus Tachycardia C. Idioventricular Rhythm D. Ventricular Tachycardia

Correct Answer is D

Explanation

A. Complete heart block (third-degree AV block) is characterized by a complete dissociation between atrial and ventricular activity, with P waves and QRS complexes occurring independently of each other.
B. Sinus tachycardia presents with a regular rhythm, a heart rate above 100 beats per minute, and distinct P waves preceding each QRS complex.
C. Idioventricular rhythm occurs when the heart's primary pacemakers fail, leading to a slow ventricular rate (usually 20-40 bpm) with wide QRS complexes and no preceding P waves.
D. Ventricular tachycardia (VT) is a life-threatening arrhythmia characterized by a rapid ventricular rate (typically >100 bpm), wide QRS complexes, and an absence of P waves. VT can be sustained or non-sustained and may require immediate intervention if the patient is unstable.
