The nurse is caring for a patient that suddenly goes into uncontrolled atrial fibrillation. To determine if the patient has an adequate stroke volume, the nurse would assess for


• A pulse deficit is when the apical pulse is greater than the radial pulse. This is due to a low stroke volume in which most of the blood flow is not reaching the periphery.

• Incorrect: A widening pulse pressure would not be expected. Instead, the nurse would assess for a narrow pulse pressure (when the difference between the systolic and diastolic pressures is less than 25% of the systolic value).

• Incorrect: Corrigan's pulse is associated with increased stroke volume and decreased peripheral resistance.

• Incorrect: O'Connor's pulse is not a real condition.
