A nurse assesses a client in labor and suspects dysfunctional labor (hypotonic uterine dysfunction). The woman's membranes have ruptured and fetopelvic disproportion is ruled out.Which intervention would the nurse expect to include in the plan of care for this client?

Choice A rationaleEncouraging a hands-and-knees position can help rotate a fetus in an occiput posterior position or relieve back pain during labor. However, in hypotonic uterine dysfunction where contractions are weak and ineffective, this positional change alone is unlikely to augment labor significantly.Choice B rationaleProviding a comfortable environment with dim lighting can reduce anxiety and promote relaxation, which might indirectly support labor progress. However, it does not directly address the issue of weak and ineffective uterine contractions characteristic of hypotonic dysfunction.Choice C rationaleAdministering oxytocin is the typical intervention for hypotonic uterine dysfunction after ruling out fetopelvic disproportion. Oxytocin is a synthetic hormone that stimulates uterine contractions, increasing their frequency, duration, and intensity to facilitate labor progress. It acts on the oxytocin receptors in the uterus, leading to smooth muscle contraction.Choice D rationalePreparing for an amniotomy (artificial rupture of membranes) might be considered to augment labor if the membranes are intact. However, since the woman's membranes have already ruptured, this intervention is not applicable in this situation. Amniotomy can sometimes stimulate or augment labor by releasing prostaglandins.
