Final answer:
To induce labor for a patient at 42 weeks gestation with a favorable cervix and no contractions, synthetic oxytocin (Pitocin) is typically administered through an IV infusion to stimulate uterine contractions and mimic the body's natural labor process.
Step-by-step explanation:
For a patient at 42 weeks gestation who presents with a favorable cervix (4 cm dilated, 100% effaced) but no contractions, the usual course of action would be to induce labor. This is particularly important because the pregnancy is post-term. Induction of labor can be achieved using synthetic oxytocin, known as Pitocin, which is administered through an IV infusion to stimulate uterine contractions. This method is used to mimic the body's natural process where cervical stretching induces uterine contractions in what is known as a positive feedback loop, promoting further cervical dilation and effacement.
The administration of Pitocin is chosen in cases where labor must be restarted and maintained, especially when the patient's cervix is adequately dilated and effaced, indicating readiness for delivery, but the labor is not progressing due to a lack of contractions. It is essential to closely monitor the patient and the fetal well-being during this process to ensure a safe delivery.
