Final answer:
During pregnancy, the separation of the pubic symphysis around 28-30 weeks can lead to unsteadiness and a heightened risk of falls for the pregnant patient.
Step-by-step explanation:
At 28-30 weeks, the pubic symphysis separates, causing the pregnant patient to be unsteady and at an increased risk of falls. The separation of the pubic symphysis during pregnancy occurs as the body readies itself for childbirth, with hormones such as relaxion softening the ligaments to allow the pelvis to expand during delivery. However, this separation can result in pelvic girdle pain and instability, hence increasing the risk of falls for the pregnant patient.
