Final answer:
FHR accelerations are a normal fetal response to movement and do not require intervention. Uterine contractions can cause FHR accelerations.
Step-by-step explanation:
Fetal heart rate (FHR) accelerations are a normal fetal response to movement, and no intervention is needed in this case. FHR accelerations indicate that the fetus is healthy and receiving adequate oxygenation.
Maternal dehydration is not a cause of FHR accelerations. Adequate fluid intake is important during pregnancy, but it is not a treatment for FHR accelerations.
Uterine contractions can cause FHR accelerations. These contractions stimulate the release of oxytocin, which stimulates uterine wall contractions and may lead to FHR accelerations.
