Which statement is true about fetal heart rate patterns?

Which statement is true about fetal heart rate patterns?

• A. Accelerations are normal; all decelerations (early, late, and variable) are abnormal.
• B. Accelerations and decelerations are both normal patterns.
• C. Only variable decelerations are abnormal; others are normal.
• D. There are no normal decelerations in fetal heart rate.

Answer: (A)

Fetal heart rate patterns are used to judge fetal oxygenation and well‑being. Accelerations, brief increases above baseline, are reassuring and indicate a well-oxygenated fetus with intact autonomic nervous system functioning. Decelerations are dips from the baseline and are interpreted by type: early decelerations are usually benign and stem from head compression during contractions; late decelerations suggest uteroplacental insufficiency and can indicate fetal distress; variable decelerations vary in timing and depth and often relate to cord compression, with the severity guiding urgency of intervention. This statement emphasizes that accelerations are normal and that decelerations are concerning, aligning with how many exam questions frame fetal tracing: accelerations are reassuring, and the presence of decelerations generally prompts further assessment and possible intervention. In practice, you’d assess the pattern, how long the deceleration lasts, its relation to contractions, and respond with appropriate actions (e.g., repositioning, reassuring measures, or escalating care) based on the overall tracing pattern.
