When systematically auscultating a client's anterior breath sounds, the nurse should begin by placing the stethoscope over which location?

A. Sternum. Auscultating directly over the sternum does not provide optimal lung sounds. B. Lung apex. This is the best choice as auscultation should begin at the lung apex to systematically cover all lung fields. C. Clavicle. Auscultating over the clavicle does not provide optimal lung sounds. D. Aortic site. The aortic site is for heart sounds, not lung sounds.
