What is characterized by moderate variability in fetal heart rate (FHR)?

• A. Amplitude range of 0-5 BPM
• B. Amplitude range of 6-25 BPM
• C. Amplitude range of 26-50 BPM
• D. Amplitude range of over 50 BPM

Answer: (B)

Moderate variability in fetal heart rate (FHR) is defined by an amplitude range of 6 to 25 beats per minute (BPM). This range indicates that there is a healthy fetal response to stressors, with fluctuations suggesting that the fetus is well-oxygenated and experiencing an appropriate level of autonomic nervous system function. Moderate variability is an important indicator of fetal well-being during labor and can help healthcare providers assess the need for intervention. Variability below 6 BPM typically suggests reduced fetal movement or potential fetal distress, while variability above 25 BPM may indicate hyperactivity or other concerns. Therefore, identifying an amplitude range of 6-25 BPM as moderate variability indicates that the fetal heart is responding adequately to changing conditions, which is essential for fetal health monitoring.
