Simulated
The nurse is planning a staff development conference about the causes of labor dystocia. It would be correct for the nurse to identify which of the following may cause a delayed progression during labor? Select all that apply.
Correct answer
A, C, E
Rationale
Magnesium sulfate (A) can relax uterine muscles, slowing contractions and causing dystocia. Uterine overdistention (C), such as from polyhydramnios or multiple gestations, can impair effective contractions. Epidural analgesia (E) may reduce maternal pushing efforts and prolong labor. Oxytocin infusion (B) typically augments labor, not delays it. Hypoglycemia (D) is not a direct cause of labor dystocia unless it severely impacts maternal energy levels, which is less common.
