A nurse is caring for a client diagnosed with heart failure and atrial fibrillation. The client reports feeling palpitations and shortness of breath. The nurse is aware that clients with atrial fibrillation are at risk for which complication?
Hypertensive crisis
Cardiogenic shock
Embolic cerebral vascular accident
Flash pulmonary edema
The Correct Answer is C
A. Hypertensive crisis is not a direct complication of atrial fibrillation. It is typically caused by uncontrolled hypertension rather than arrhythmias.
B. Cardiogenic shock can occur in severe heart failure but is not a primary complication of atrial fibrillation.
C. Embolic cerebral vascular accident (stroke) is a major risk for clients with atrial fibrillation. The irregular atrial contractions allow blood to pool in the atria, increasing the risk of clot formation. If a clot dislodges, it can travel to the brain and cause a stroke.
D. Flash pulmonary edema is a complication of acute decompensated heart failure but is not directly caused by atrial fibrillation.

C. Benazepril is an angiotensin-converting enzyme (ACE) inhibitor used to treat hypertension rather than causing it.
D. Obstructive sleep apnea (OSA) is a known risk factor for hypertension due to intermittent hypoxia and increased sympathetic nervous system activity, which contribute to elevated blood pressure.
Correct Answer is A
Explanation
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.
