A nurse auscultates the heart of Anne, a 21-year-old female. Anne seeks a consultation for dizziness and easy fatigability. During assessment, the nurse identifies a mid-to-late systolic click followed with mid-to-late systolic murmur at the cardiac apex. The murmur gets louder when Anne stands up. Based on these findings, Anne is most likely considered for which of the following cardiac problems?
  1. Aortic stenosis
  2. Mitral valve prolapse
  3. Pulmonic stenosis
  4. Mitral regurgitation
Explanation
Answer: B - The client is most likely considered for mitral valve prolapse. Mitral valve prolapse is a cardiac condition in which the valve found between the left atrium and left ventricle does not shut down as it should, causing a backflow of blood. Aortic stenosis is manifested by crescendo-decrescendo systolic murmur. Pulmonic stenosis causes wide splitting of the second heart sound. Mitral regurgitation is manifested by high-pitched holosystolic murmur with the first heart sound and extending to the second heart sound.
