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.

Correct Answer is B
Explanation
A. Lidocaine is used for ventricular arrhythmias, not supraventricular tachycardia (SVT).
B. Adenosine is the first-line treatment for stable SVT, as it temporarily blocks AV node conduction, allowing the heart to reset into a normal rhythm. It is given as a rapid IV push.
C. Atropine increases heart rate and is used for bradycardia, not tachycardia.
D. Epinephrine stimulates the heart and is used for asystole and severe bradycardia, not SVT.
Correct Answer is C
Explanation
A. A prolonged PR interval can be seen in hyperkalemia but is not as characteristic as peaked T waves.
B. A U wave is typically seen in hypokalemia, not hyperkalemia.
C. Peaked T waves are a hallmark ECG finding in hyperkalemia and occur due to increased repolarization speed.
D. ST segment elevation is more commonly associated with myocardial infarction rather than hyperkalemia.
