The nurse is preparing to assess the apical pulse. At which location should the nurse listen to obtain an accurate apical pulse on an adult patient?
a. At the fifth intercostal space at the left sternal border
b. At the fifth left intercostal space at the midclavicular line
c. At the second intercostal space at the left midclavicular line
d. At the second right intercostal space at the midclavicular line
B
To auscultate an adult's apical pulse, the nurse places the stethoscope at the left fifth intercostal space at the midclavicular line directly over the point of maximal impulse and the location for auscultating the mitral valve. The fifth left intercostal space at the left sternal border locates the tricuspid valve. The second intercostal space at the left midclavicular line locates the pulmonic valve. The second right intercostal space at the midclavicular line locates the aortic valve.
