A nurse is caring for a client with chest pain who becomes unresponsive. The client is pulseless and apneic. The code team places the client on the monitor, which indicates ventricular fibrillation. What is the next priority action?

Amiodarone administration

Defibrillation

Epinephrine administration

Synchronized Cardioversion

Answer and Explanation

The Correct Answer is B

A. Amiodarone is an antiarrhythmic medication used after defibrillation and CPR in persistent ventricular fibrillation (VF) or ventricular tachycardia (VT). However, it is not the first priority.
B. Defibrillation is the immediate priority in a pulseless client with ventricular fibrillation. Early defibrillation increases the chances of survival. The shock should be delivered as soon as possible.
C. Epinephrine is given after the first defibrillation and CPR cycle, not before.
D. Synchronized cardioversion is inappropriate because it is used for unstable tachyarrhythmias with a pulse, not pulseless VF.

Correct Answer is A

Explanation

A. Stage 1 hypertension is classified as a systolic BP of 130-139 mm Hg or diastolic BP of 80-89 mm Hg. While the readings provided are close, the higher diastolic value of 88 mm Hg falls into the Stage 1 hypertension category.
B. The term prehypertension is outdated and replaced by elevated BP, which refers to systolic 120-129 mm Hg and diastolic <80 mm Hg. The client’s diastolic values are too high for this category.
C. A normal BP is <120/80 mm Hg, and the client’s readings exceed this range.
D. Stage 2 hypertension is ≥140/90 mm Hg, which does not apply to this client.

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.
