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

Answer and Explanation

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 A

Explanation

A. Counting the number of QRS complexes in a 6-second strip and multiplying by 10 provides an estimate of the heart rate per minute.
B. Measuring T waves is used to assess repolarization abnormalities, not to determine heart rate.
C. While the monitor provides a heart rate reading, manual calculation is essential for verifying accuracy.
D. P waves indicate atrial activity but are not used to calculate the overall heart rate.

A. Blood pressure reading of 110/70 and heart rate of 90 B. Swelling at the insertion site and cool extremity C. Oozing blood from the puncture site D. The client has not voided since returning to recovery

Correct Answer is B

Explanation

A. A blood pressure of 110/70 and heart rate of 90 is within normal limits and does not indicate an immediate complication.
B. Swelling at the insertion site and a cool extremity suggest arterial occlusion or hematoma formation, which is a serious complication requiring immediate intervention. This may indicate impaired blood flow to the limb.
C. Oozing blood from the site may require monitoring and pressure application but is not as concerning as signs of arterial compromise.
D. Not voiding post-procedure can be due to bedrest or IV contrast, but it is not an urgent concern.
