A patient who recently completed a multigated blood pool imaging (MUGA)scan asks what it means that the test showed an ejection fraction of 65%.Which answer by the nurse is most accurate?
A)"This scan shows that your heart was affected by a heart attack at some time in the past, since your ejection fraction is below average."
B)"The ejection fraction shows the effectiveness of the pumping function of the ventricles.A normal ejection fraction is 55% to 65%."
C)"Since the ejection fraction is so low, these results indicate that your heart does not pump as effectively as it should when you are exercising."
D)"Your health-care provider will follow up with you, but your results will require treatment since your ejection fraction was so high."

The ejection fraction is a measure of the effectiveness of the pumping function of the heart. A normal ejection fraction is typically between 55% and 65%. Option A is not accurate since a low ejection fraction does not necessarily indicate a past heart attack. Option C is also not accurate as there is no indication that the patient was exercising during the MUGA scan. Option D is not accurate since a high ejection fraction is actually a good thing and does not require treatment.
