A nurse is assisting in the care of a client who is in active labor. The nurse notes variable decelerations of the FHR. The nurse should identify which of the following as a cause of variable decelerations?

Choice A reason: Fundal consistency is correct, as this finding can indicate the effectiveness of oxytocin in stimulating uterine contraction and preventing postpartum hemorrhage. Oxytocin is a uterotonic agent that can enhance or augment uterine contractility and involution. The nurse should monitor the fundal height, consistency, and position and report any signs of uterine atony or excessive bleeding.

Choice B reason: Fetal heart rate is incorrect, as this finding is not relevant for a client who has already delivered the baby. Fetal heart rate can indicate the fetal well-being and response to labor, but it is not affected by oxytocin administration after birth. The nurse should monitor the newborn's vital signs and appearance and report any signs of distress or infection.

Choice c reason: Urinary output is incorrect, as this finding is not specific for evaluating the effectiveness of oxytocin. Urinary output can indicate the client's renal function and fluid balance, but it can be influenced by many other factors, such as fluid intake, bladder distension, or epidural anesthesia. The nurse should monitor the client's intake and output and report any signs of oliguria or retention.

Choice D reason: Blood pressure is incorrect, as this finding is not specific for evaluating the effectiveness of oxytocin. Blood pressure can indicate the client's hemodynamic status and response to blood loss, but it can be influenced by many other factors, such as pain, anxiety, preeclampsia, or medication. The nurse should monitor the client's vital signs and fluid balance and report any signs of hypotension or hypertension

Choice A reason: Fundus soft, 2 fingerbreadths below the umbilicus is incorrect, as this finding indicates uterine atony and subinvolution. The fundus is the upper part of the uterus that can be palpated through the abdomen after birth. The fundus should be firm and midline to indicate adequate uterine contraction and involution. A soft or boggy fundus can increase the risk of hemorrhage and infection.

Choice B reason: Fundus firm, 1 fingerbreadth below the umbilicus is correct, as this finding indicates normal uterine contraction and involution. The fundus is normally at the level of the umbilicus immediately after birth and then descends about one fingerbreadth per day. A firm and midline fundus can prevent excessive bleeding and promote healing.

Choice C reason: Fundus firm, 4 fingerbreadths above the umbilicus is incorrect, as this finding indicates a higher than expected fundal height for a client who is 24 hr postpartum. The fundus is normally at the level of the umbilicus immediately after birth and then descends about one fingerbreadth per day. A high fundal height can indicate uterine atony, retained placental fragments, or bladder distension.

Choice D reason: Fundus soft, to the right of the umbilicus is incorrect, as this finding indicates uterine atony and bladder distension. The fundus should be firm and midline to indicate adequate uterine contraction and involution. A deviated fundus can indicate bladder distension, which can interfere with uterine contraction and involution and increase the risk of hemorrhage and infection.
