Final answer:
Leopold's maneuvers are used by practitioners to determine the best location to assess the fetal heart rate (FHR) by palpating the abdomen.
Step-by-step explanation:
Leopold's maneuvers are used by practitioners to determine the best location to assess the fetal heart rate (FHR). These maneuvers involve palpating the abdomen to feel the position, presentation, and engagement of the fetus. By doing this, practitioners can locate the optimal spot to listen to the FHR using a Doppler or a stethoscope.
