Final answer:
The most common adverse effect of oxytocin (Pitocin) during labor induction is uterine tachysystole, which involves excessive uterine contractions.
Step-by-step explanation:
When talking to the patient about the adverse effects of oxytocin (Pitocin) used to initiate labor contractions, the nurse should understand that the most common adverse effect of the drug includes uterine tachysystole. Oxytocin, an endocrine hormone secreted by the pituitary gland, plays a critical role during childbirth to stimulate uterine contractions. In a positive feedback loop, as contractions increase, more oxytocin is released, which can potentially lead to excessive contractions, known as tachysystole. It is essential for healthcare providers to monitor the frequency and intensity of contractions to manage the risk of tachysystole during labor induction with oxytocin.
