Final answer:
The client in active labor is exhibiting signs of b) Early decelerations.
Step-by-step explanation:
The client in active labor is exhibiting signs of b) Early decelerations.
Early decelerations are a common finding during labor and are characterized by a gradual decrease and return to baseline of the fetal heart rate (FHR) in response to uterine contractions.
In this case, the FHR is ranging from 115 to 125/min with occasional increases up to 150 to 155/min that last for 25 seconds. This pattern of decelerations is considered normal and is typically caused by head compression during contractions.
