Fetal accelerations are a sign of fetal well-being. Which option best reflects this?

• A. They indicate fetal distress
• B. They indicate fetal well-being
• C. They indicate maternal fever
• D. They indicate dehydration

Answer: (B)

Fetal accelerations show the fetus is well-oxygenated and actively responding to stimuli. When the fetus moves or is stimulated, the autonomic nervous system prompts a brief rise in heart rate above the baseline. This temporary increase demonstrates intact heart rate regulation and adequate placental gas exchange, signaling fetal reserve and well-being. In contrast, patterns of concern are decelerations (especially late or recurrent variable decelerations) that suggest potential hypoxia or uteroplacental insufficiency. Maternal fever points to infection and can affect the fetus, and dehydration can influence perfusion, but neither is a sign of fetal well-being like accelerations are.
