ANS: A
Gallop rhythms generate low-pitched sounds and are most easily heard with the bell of the steth-oscope. Sounds associated with the mitral valve are accentuated by turning the patient to the left side, which brings the heart closer to the chest wall. The diaphragm of the stethoscope is best to use for the higher-pitched sounds such as S1 and S2.
