The nurse is preparing to take an apical pulse on an assigned client. The nurse places the diaphragm of the stethoscope at which cardiac site?
1. Aortic area
2. Mitral area
3. Tricuspid area
4. Pulmonic area
2
Rationale: The diaphragm of the stethoscope is placed directly over the skin at the mitral area (the fifth intercostal space left midclavicular line) to listen to the apical pulse. S1 (lub) and S2 (dub) should be distinguished. The pulse should be counted for a full minute. Therefore "aortic area," "tricuspid area," and "pulmonic area" are incorrect sites.
