74. A nurse gets a report that a client will be admitted with an ejection fraction of 58%. Which history and physical finding should the nurse anticipate?

Choices

Choices ⬆ ⬇

1. Inspiratory wheezing in upper lobes, bilaterally.

2. O2 saturation that increases from 90% to 99% when head of bed is lowered to a flat position.

3. Crackles in the lung bases that clear with deep breathing.

4. A client is unable to walk up two flights of stairs without dyspnea.

Question  Hint

Hints ⬆ ⬇

Test-Taking Tip

Know the average ejection fraction (60% to 70%). Select a finding that would be consistent with mild heart failure.

1.  

Answer 1 is correct because bilateral adventitious sounds are heard early in left-sided failure. The ejection fraction is below the normal for a health heart (60% to 70%). Answer 2 is incorrect because the low O2 saturation is related to pulmonary congestion and heart failure. A flat position may aggravate the client's condition. Answer 3 is incorrect because crackles due to heart failure would not clear with deep breathing and coughing. Answer 4 is incorrect because the ejection fraction is on the low side of normal (60% to 70% for a healthy heart). Fatigue would be more common. This degree of activity intolerance would increase as heart failure progressed.
